The Bavarian Energy Prize

And they do exist: innovative energy solutions that have already been implemented and are advancing the energy transition! Most recently, on October 19, 2022, six outstanding projects with a role model function were awarded the Bavarian Energy Prize by the Bavarian Ministry of Economic Affairs. All of the award-winning projects have one thing in common: The solution to our energy and climate crisis lies in the responsible use of energy. In addition to renewable energy generation, energy must above all be used as efficiently as possible. This is achieved in exemplary fashion in the Energy Prize projects through maximum waste heat utilization, intelligent control, energy conversion and the coupling of the electricity, heat and mobility sectors.

AGO GmbH Energie und Anlagen wins the Bavarian Energy Award 2022

AGO GmbH Energy + Systems

Munich, 19.10.2022 - The Bavarian Energy Prize 2022 of the Bavarian State Ministry of Economic Affairs, Regional Development and Energy was awarded today to AGO GmbH Energie + Anlagen. The Kulmbach-based company received the main prize for its newly developed high-temperature heat pump for industrial and municipal heat supply. The prize is awarded to companies in Bavaria that excel in the fields of new energy technologies, renewable energies and energy efficiency.

AGO GmbH Energie + Anlagen from Kulmbach received the award for the world's first high-temperature heat pump called "AGO Calora", which it developed on the basis of the natural substance pair ammonia/water and with which a heat supply of up to 150 °C is possible.
The heat demand in industry and also in district heating supply is often at temperatures well above 100 °C and has so far been covered almost exclusively by burning fossil fuels. Together with Stadtwerke Neuburg an der Donau, AGO therefore built a first demonstration plant last year with a heating capacity of approx. 1 megawatt, in which the heat from a low-temperature heating network is used as a heat source and fed into a hot water network to supply a malting plant at 135 °C. With this successfully patented heat pump solution, a CO2-free heat supply on an industrial scale of approx. 0.5 megawatts to approx. 10 megawatts per heat pump and uniquely high efficiency is possible.
Managing Director Günther Hein, who is responsible for the technical area, is delighted with this award and emphasizes: "The AGO Calora high-temperature heat pump developed by AGO is an important building block for the transformation of municipal and industrial heat supply in Germany, especially in today's world."

BSH site in Dillingen receives Bavarian Energy Award

BSH Hausgeräte GmbH

Dillingen, 20.10.2022 - The BSH site in Dillingen received the Energy Award in the category of energy efficiency in industrial processes and production as well as energy efficiency networks on October 19. Innovations in the core processes of metal processing have enabled the plant to massively reduce its natural gas and electricity consumption.

The BSH site in Dillingen is the largest employer in the region and one of the largest sites of BSH Hausgeräte GmbH worldwide. More than 2,700 employees work here in the development, production and delivery of over 2.5 million dishwashers every year.
The plant is one of the most modern in the world - the site sets standards for resource-saving dishwashers: "We create innovations that enable us to make not only our appliances but also our production more environmentally friendly and sustainable. We always have our sights firmly set on the future and focus on our pioneering role in the industry, including when it comes to environmental protection and Industry 4.0 technologies," explains site manager Claus Köther.

One of these innovations within production has now been honored with the prestigious energy award. Among other things, the plant manufactures the metal inner containers that form the core of the dishwashers. The previous welding process, which was more susceptible to corrosion, always required passivation and washing systems. Passivation is used to protect the containers from corrosion, and the liquids used in the process then have to be washed off afterwards. "We now use laser welding technology and biodegradable lubricants and leak testing agents - this eliminates the need for passivation and washing and the associated use of energy and resources," explains project manager Aytekin Göksen. These two processes were previously two of the site's biggest energy consumers. By eliminating these two work steps, more than 6.6 million kilowatt hours of electricity and gas and 1,650 tons of CO2 can now be saved each year.

The award ceremony was held on October 19 in Munich by the Bavarian Minister of Economic Affairs, Hubert Aiwanger.

Project "Flexible biogas utilization with maximum efficiency"

Reverion GmbH

Project "Flexible biogas utilization with maximum efficiency"

"The Bavarian Ministry of Economic Affairs has been awarding the Bavarian Energy Prize for the most innovative energy projects in Bavaria since 1999. We are therefore extremely pleased to have won this year's award in the "Energy generation - electricity, heat" category for the development of our Reverion power plant technology for flexible biogas utilization with maximum efficiency. This award confirms that we are on the right path to a future with 100% renewable energy." Stephan Herrmann, Managing Director of Reverion.

Reverion technology can double the amount of electricity generated from the same amount of biogas thanks to higher electrical efficiencies. In addition, the same plant can switch to electrolysis mode to produce green hydrogen or methane from electricity. The synthetic, renewable natural gas from Reverion plants can be used for electricity, heat or mobility via the existing natural gas grid. A long-term storage effect is achieved by using the existing gas infrastructure. The existing infrastructure in Germany has a storage capacity of around 400 TWh, 100,000 times the total installed battery storage capacity. These systems are therefore ideally suited to both stabilizing the electricity grid and storing energy on a seasonal basis.

In addition, pure, storable CO2 is captured and enables cost-efficient, negative CO2 emissions for the first time. The technology could reduce CO2 emissions in Bavaria by almost 30% simply by using the biogas already produced.

The technology consists of modular, scalable, standardized container units. These are designed for series production and plug & play installation to easily replace existing gas engines and enable rapid market penetration.

Reverion

As a spin-off of the Technical University of Munich, Reverion has developed and patented a revolutionary container-based power plant for biogas. With a founding team that has more than 30 years of experience in the energy sector and a highly motivated team of more than 25 employees, Reverion is opening up new optimization potential in the biogas market and ushering in a new era of highly flexible, efficient and decentralized energy supply.

Why Bavaria (urgently) needs our solution

As the current geopolitical situation in Europe worsens, the urgency of the energy crisis is increasing. Germany covers 27% of its primary energy consumption with natural gas. 95% of this gas is imported, and 55% of imported gas has so far come from Russia. This means that 15% of Germany's total primary energy consumption is dependent on Russian natural gas.

Currently, German biogas capacity could cover up to a maximum of 22% of Russian gas. With our technology, however, this share can be increased to 44 % without additional land consumption.

Altdorf flex market: Decentralized flexibility in grid-serving real operation

FfE Munich - Bayernwerk Netz GmbH

Munich/Regensburg, 19 October 2022: Bavarian Energy Award 2022 for FfE München and Bayernwerk Netz GmbH in the category "Energy distribution incl. grid services - heat, electricity, gas etc. and storage technologies" for the Altdorfer Flexmarkt project: Decentralized flexibility in real grid-serving operation.

The transformation of the energy system is accompanied by a fundamental change: away from centralized, fossil-based supply structures towards a decentralized, renewable system. This development makes the electricity grids the "backbone of the energy transition". With an exchange platform, the Altdorf Flexmarkt represents a concept for using the flexibility available in the electricity grid. The target group of the practical test, which was carried out in Altdorf in the district of Landshut from October 2019 to the end of 2020, are owners and operators of flex options, i.e. controllable energy generation and consumption systems. With the help of smart metering systems (iMSys), feed-in and consumption peaks can be reduced and the electricity grid can be optimally utilized. "Concepts such as the Altdorf flex market will make it possible to integrate more renewable energy and new consumers into the existing grid in future and avoid grid bottlenecks," says Simon Köppl (FfE), project manager of the Altdorf flex market.
The Altdorf flex market was developed and tested by FfE, an energy industry research institute from Munich, and the grid operator Bayernwerk Netz as part of the C/sells project. The Altdorf flex market integrates small-scale systems such as heat pumps, electric vehicles and PV systems into the grid operators' grid congestion management via market mechanisms. This gives new players the opportunity to participate in the energy transition and also to market their products. The resulting competition leads to cost efficiency in the elimination of grid bottlenecks and to savings in CO2 emissions.
The Altdorf Flexmarkt places great emphasis on the participation of the local population. In addition to information events, the activation of intrinsic motivational reasons, such as actively contributing to the energy transition, are considered important success factors. The inclusion of regional role models also proved to be decisive. In addition to citizen dialogs, the project gained a high profile in the region with the active support of the mayor of Altdorf as a field test participant with a municipal system and aroused interest in participating.
Intelligent metering systems ensure the technical implementation, guaranteeing the secure transmission of measured values and switching commands. Extensive analyses of the reliability, latency times and data volumes of the infrastructure showed that the iMSys infrastructure is suitable for grid-serving applications. The development and demonstration of the Altdorf flex market is considered a key component of future-proof distribution grids. The project has shown that an interplay between science and practice enables the needs-based and scalable implementation of innovations for the energy transition and thus takes the interests of citizens into account.

WUNsiedler Weg Energie: Away from silo thinking, towards sector coupling

SWW Wunsiedel GmbH

The goal of SWW Wunsiedel GmbH is clear: to supply one hundred percent of households and industry with renewable energy from the sun, wind, biomass and residual materials. An intelligent connection of the electricity, heating, mobility and industrial sectors as well as energy producers and consumers is essential for this. SWW won the Bavarian Energy Award in the category "System-compatible sector coupling - electricity, heat, mobility" with its project "The WUNsiedler Way to Energy - Coupling the Sectors".

"Networking is the only way to fully utilize every available resource," says SWW Managing Director Marco Krasser. And that, in turn, is necessary in order to become completely independent of fossil fuels. Coupling the sectors would also ensure the necessary balance between electricity consumption and electricity generation. Furthermore, regional economic cycles increase value creation in the region and thus acceptance among the population.

SWW and its subsidiaries are currently operating or building two large electrical storage facilities, several small electrical storage facilities, heat storage facilities of various sizes including a large heat storage facility and a pellet plant. In addition, WUN H2 GmbH, in which SWW holds a stake, is building an electrolyzer to produce green hydrogen that can be stored in the local natural gas grid. Siemens AG is an important technology partner for this and other projects.

The H2 production plant is exemplary of the overarching goals of the WUNsiedler Weg: if there is too much green electricity available, it will be used for H2 production. If there is too little electricity, for example during a dark doldrums, the hydrogen can be burned in combined heat and power plants. The resulting heat is fed into the local heating network. Surplus electricity from the CHP process is used to operate heat pumps, for example. The waste heat from the electrolyser will also be used, as will the oxygen that is produced alongside the hydrogen. Overall, this results in a very high efficiency of around 90% thanks to sector coupling, which is currently only realized at a few locations in Germany.

Ultimately, a "network of networks" is created across different sectors and levels, explains Krasser. "We are coupling the sectors at one level as well as across the different grid levels." This requires sector-specific storage options and, ultimately, every building and every industrial operation will become a grid-serving power plant.

SWW Wunsiedel GmbH is a subsidiary of the town of Wunsiedel. Its business areas include the supply of electricity, gas, water and heat as well as telecommunications. Subsidiaries include WUN Bioenergie GmbH and WUN Pellet GmbH. Together with Siemens Financial Services and Rießner Gase GmbH, SWW has founded WUN H2 GmbH.

Bavarian Energy Award 2022 in the category "Building as an energy system / building concept"

RAAB Baugesellschaft - Nuremberg Institute of Technology

Project: Herzo Base energy storage buildings - an energy-flexible building and energy concept of tomorrow

Award winners: RAAB Baugesellschaft GmbH & Co KG from Ebensfeld (Upper Franconia) and Nuremberg Institute of Technology / Energy Campus Nuremberg

This pioneering research project impresses with its innovative climate-neutral building and energy concept with regenerative energy technology. State-of-the-art building materials were used in the healthy, environmentally friendly construction method. In Herzogenaurach, a real project has been created with eight PlusEnergy houses, in which efficient synergy effects have been created by combining the buyers to generate and use energy together.

Managing Director Gisela Raab says: "The award will be an incentive for us to continue our commitment to sustainable construction and climate protection. We see the implementation of meaningful and climate-friendly residential projects with community concepts as a goal-oriented approach." RAAB Baugesellschaft mbH & Co KG is a medium-sized family business, founded in 1898 and successfully managed by the fourth and fifth generation.

The energy-efficient approach to the construction project was developed by scientists at Nuremberg Institute of Technology (THN), who found RAAB Baugesellschaft to be a forward-looking partner for a shared, highly topical vision of creating climate-neutral buildings. The project was implemented with industrial partners and the architecture firm Bär Kühhorn from Nuremberg.

The exterior walls were made of highly insulating bricks. The POROTON bricks used were equipped with the high-performance insulating material CALOSTAT from Evonik at the Energie Campus Nürnberg (EnCN). This made it possible to achieve extremely low U-values of 0.13 W/(m²K) for the building envelopes. "We used the brick with the best thermal insulation in the world today and were able to improve the insulation by 28 percent compared to bricks with pure perlite filling," says Prof. Dr. Wolfgang Krcmar from the Faculty of Materials Technology at THN and Chairman of the Scientific Management of EnCN. The exterior wall constructions of all the houses are built differently and are compared with each other in terms of their insulating properties.

The innovative energy concept includes a system integration of several energy generators, a PV system with 88 kWp with east-west orientation, geothermal energy with 2 brine/water heat pumps, 7 deep boreholes as well as thermal and electrical storage (39 kWh batteries). Passive cooling was integrated for room temperature control. The PV-optimized and predictive operation management for charging and discharging the storage units makes targeted use of the central storage technologies in the energy network of the building. This is made possible by a shared energy center for all eight buildings in the basement. Predictive control technology, also taking into account weather data and forecasts and specially developed software, enables sensible, digitally controlled and particularly optimized energy use.

The buildings are evaluated in terms of their energy efficiency over several years. To this end, a large number of sensors were installed in the building envelopes and at key energy-related points to enable measurements of physical parameters while the building is occupied. "The targeted values for an energy-plus building have been achieved and in some cases exceeded," says Prof. Dr. Arno Dentel, Faculty of Mechanical Engineering and Supply Technology at THN and project partner in EnCN. "The residential complex is self-sufficient in the annual balance and feeds more electricity into the grid over the course of the year than it draws from it. This shows how important the interaction between passive thermal insulation and active energy-saving measures is." The scientific part of the project was funded by the Federal Ministry for Economic Affairs and Energy (grant no. 03ET1364A).

The average cost of heating energy for 2021 was 375.00 euros per year per house with 155 m² of living space. The PlusEnergy building complex generates more energy over the year than it consumes.
The healthy homes were sold at competitive prices on the open real estate market. The building is a demonstration object for sustainable construction and a real contribution to the energy transition.

Kurtz GmbH main prize winner of the Bavarian Energy Award 2020

Kurtz GmbH

Award for Kurtz GmbH's radio frequency technology

Kreuzwertheim/Nuremberg, 23.10.2020 - Every two years, the Free State of Bavaria awards the "Bavarian Energy Prize" for outstanding achievements in the field of energy. After beating its competitors in the category "Energy efficiency in industrial processes and production as well as energy efficiency networks", Kurtz GmbH has now also received the main award from eight prize-winning categories during a ceremony with State Minister Hubert Aiwanger at the Ministry of Economic Affairs in Munich. RF-Technologie impressed the expert jury with its project "Chemical-free recycling of EPS material using RF fusion technology". Kurtz Ersa CEO Rainer Kurtz is delighted with the award: "The welding of particle foams using electromagnetic waves is extremely promising and is revolutionizing the production of moulded parts. Winning the main prize is both an honor and an incentive and a welcome component of our ambitious sustainability program."

RF fusion technology saves 90% energy

The plastics industry has been looking for alternative manufacturing processes for years. The fusion of particle foams using highly efficient radio frequency technology is revolutionizing processing in terms of sustainability. Compared to the manufacturing process using steam, up to 90% energy can be saved. By eliminating the steam generation systems previously required, it is possible to significantly improve the CO2 footprint of particle foam manufacturers. The machine is also equipped with an all-electric drive. The use of electromagnetic waves in the radio frequency range enables optimum welding to be achieved. In addition, new materials and even biodegradable materials can be processed. This processing was not technically feasible in standard machines due to the high pressures required. The top advantage of RF fusion technology is that the particle foam material can only be returned to the cycle by mechanical "shredding". The WAVE FOAMER shines with a reusability of up to 100%. With EPS in the previous steam process, only a maximum of 20% of recycled material can be reused.

About Kurtz Ersa

Kurtz Ersa is an owner-managed family business in its 6th generation with headquarters in Spessart and a company history of over 240 years. As a mechanical engineering and technology group with a global presence, it focuses on long-term and sustainable growth. 1,200 employees work every day to advance the technologies and solutions of the Electronics Production Equipment, Molding Machines and Automation divisions.

IGS - Engineering office for energy and environmental technology - Brauerei Aying Franz Inselkammer KG

Bottle washer with high-temperature heat pump in conjunction with a combined heat and power unit

We are very proud that the expert jury has selected us as the winner of the Bavarian Energy Award 2020 in the category "Energy efficiency in industrial processes and production".
The engineering office for energy and environmental technology was founded by Dr. Georg Schu in 1990, i.e. 30 years ago. In the meantime, it has grown into three companies that work closely together. For larger projects, we are also happy to work with reliable and competent project partners. A number of patents have also been registered over the years.
Our activities have always focused on energy consulting, planning energy systems and their implementation. The main sector is breweries here and worldwide, but we are also active in many other sectors.

We share the prize with the Aying brewery for our willingness to use a new, innovative process in practical operation. This was the first time the process was used on an industrial scale. We would like to thank Krones AG and the plant in Flensburg for implementing the process in a new bottle washer.

The cleaning of returnable bottles accounts for a significant proportion of the energy and water requirements of breweries. Heat is extracted from the cooling area of the bottle washer via external heat exchangers and fed to a heat pump.

This drastically reduces the amount of water required to cool the bottles. In addition, waste heat from a combined heat and power plant is added so that the heat output of the heat pump can completely cover the heating requirements of the bottle washer.

The heat pump's electricity requirements are covered by the existing combined heat and power plant. This has significantly increased the running time of the existing combined heat and power plant and thus its economic efficiency.
Compared to the old bottle washer, the new process has reduced water and heat consumption by 87% each.
The development and implementation of the project was funded by the Federal Ministry for the Environment as part of the environmental innovation program. We would like to take this opportunity to express our thanks for this.

We are donating the entire prize money to UNICEF to help feed malnourished children in South Sudan.

ENVER - Freilassing Energy Network

City of Freilassing

The foundation stone for the Freilassing energy network was laid back in 2011/12 with the general refurbishment of two Freilassing schools and the municipal library.

As the energy supply for the new "Badylon" sports and leisure facility with its triple sports hall and indoor swimming pool had to be replanned anyway, the opportunity was taken to investigate and implement an energy network between several municipal buildings.

The Freilassing energy network supplies the Badylon sports and leisure facility, the primary and secondary school, the municipal sewage treatment plant and the youth clubhouse with district heating over a total pipe length of 936 meters. The supply is provided by combined heat and power plants, which are mainly supplied with sewage gas from the sewage treatment plant and run on natural gas as a secondary fuel. In addition, a biomass boiler is used, which can also utilize municipal green waste.

"Parallel to the heating network, an electricity network was set up between the aforementioned municipal buildings. In this form, such an energy generation network is unique," says Freilassing's mayor Markus Hiebl. The electricity is supplied by several photovoltaic systems and the combined heat and power plants in the sewage treatment plant and the heating center. From an energy law perspective, the buildings spread across the town form a separate area that supplies itself entirely with heat and to a large extent with electricity.

The Freilassing energy network is an alternative to large-scale electrical storage systems, which are already being implemented in some municipalities but are still very expensive and resource-intensive to produce. The model implemented in Freilassing can serve as a blueprint for a large number of other Bavarian municipalities that want to make the best possible use of their local renewable resources and reduce their energy costs.

Green Factory - The CO2-neutral factory

Alois Müller GmbH

The Green Factory is a role model for CO2-neutral production in practice: the 18,000 m2 production and office building of the Alois Müller Group at the Ungerhausen site (Allgäu) is virtually energy self-sufficient and boasts a sustainable and energy-flexible concept that can also be implemented for other companies in Germany. The energy comes from a photovoltaic system, a combined heat and power plant and a pellet heating system powered by renewable raw materials. Different storage media compensate for possible fluctuations in generation. To ensure that the climate-friendly energy generated is used in the best possible way, the entire production process is coordinated with electricity generation.

"Our Green Factory is unique in Germany - but it doesn't have to stay that way. On the contrary: the concept of the Green Factory, i.e. the generation of solar power, the demand side management applied, the sector coupling practised and the internal intelligent power grid, the so-called smart grid, can be adapted for almost all companies in Germany," explains Andreas Müller, Managing Director of the Alois Müller Group. Companies that want to see this for themselves can visit the Green Factory. "If required, we can also present all the components with the necessary key figures," Müller continues.

An important prerequisite for climate-neutral production is the analysis of all material and energy flows required for the production steps. An ERP system (ERP for Enterprise Resource Planning) is used to compare the order situation and production data with the regenerative energy data. Production steps are thus adapted to the availability of solar power.
The Green Factory went into operation in summer 2019. Here, the Alois Müller Group manufactures ventilation ducts and supply technology components for plant engineering, such as steel and stainless steel piping systems, containerized energy centers and energy module systems. More than 250 people work on the company premises in production and administration. The Alois Müller Group also operates its own electric charging station at the Ungerhausen site, which is also available to external vehicles, using the electricity it produces itself in the Green Factory.

About Alois Müller
Since 1973, the Alois Müller Group has grown from a traditional family business to a medium-sized, owner-managed company with over 600 employees at twelve locations. Alois Müller specializes in energy and building technology (heating, ventilation, sanitary, refrigeration, electrical) as well as industrial plant engineering. In line with the company motto "Focus on energy", the emphasis in all projects is on innovative, cost- and energy-efficient solutions without compromising user comfort. Regionally connected and nationally active, the group of companies stands for solid craftsmanship and well thought-out solutions. Alois Müller has consistently developed from a traditional craftsman's business into one of the industry's leading technology partners.

heilergeiger architects and urban planners BDA - Alois Goldhofer Foundation

The structural concept for the daycare center developed from the Reggio pedagogy applied in it, which was deliberately chosen by the client, the non-profit Alois Goldhofer Foundation. Here, the reuse of the used and its creative utilization are essential elements. For this reason, the founder's family's old home was reused and its existing structure activated. The three parts of the building were preserved, exposed and placed under a new, translucent shell. The resulting spaces between old and new are an extension of the daycare functions and an element of the sustainable energy concept.

"The new shell made of recyclable polycarbonate is a collector of light and energy. It allows the existing walls to remain uninsulated and, in contrast to the conventional 'insulating sweater', the energy-efficient refurbishment creates new space," say the architects. In the cold seasons, the passive solar energy generated by the façade is used to keep the building warm. In summer, the storage mass of the existing building and a rainwater cistern support the natural cooling of the house.

The energy concept is thus an interplay of space, light, construction and use. By retaining 75% of the existing building as far as possible and thus reducing additional "gray energy", the strengths of the existing building are used for climate protection. The regenerative share of 82% for heating and cooling reduces CO2 consumption, which at 4.98 kg/m²a already corresponds to the 2050 climate target. Accordingly, the energy and ecological concept of the Reggio idea also follows the appreciation and activation of what already exists. Reuse of the existing building, conservation of resources and sustainable energy generation can thus be experienced by the children in the architecture.

Climate protection and the necessary ecological change are socially relevant issues for heilergeiger. That is why planning and building must be sustainable. As architects, they ask the questions:
How do we use existing buildings and conserve resources? How do we reduce CO2 and gain space at the same time? How can climate protection be experienced as a spatial enrichment?

Important component of the energy concept receives award

Stadtwerke Rosenheim GmbH & Co. KG - SolarNext AG

Rosenheim, 22.10.2020 - Stadtwerke Rosenheim and SolarNext AG receive the Bavarian Energy Award 2020 for their innovation project: "Environmentally friendly cooling supply at Bahnhof Nord" in the category "Municipal energy concepts". This award will be presented to Stadtwerke Rosenheim together with its partner SolarNext AG by the Bavarian State Minister for Economic Affairs, Regional Development and Energy, Hubert Aiwanger, at the award ceremony on October 22, 2020 at the Bavarian Ministry of Economic Affairs in Munich.

"We are honored to receive the Bavarian Prize 2020," said Dr. Götz Brühl, Managing Director of Stadtwerke Rosenheim. "The Bavarian Energy Award is an encouragement and incentive for us to continue our efforts and to make our experience available to other municipal utilities."

"We are very proud to have realized such a district concept using our chillii® Cooling Kit in our home region," explains Frank Molter, CEO of SolarNext AG.

Ambitious goals - well-founded concept

Stadtwerke Rosenheim is committed to a sustainable and economically viable energy supply and has been working consistently for years to achieve its ambitious climate protection goals, documented in a well-founded energy concept. The environmentally friendly cooling supply for the Bahnhof Nord district is a further development of the idea of always providing customers with energy-efficient and CO2-minimized cooling. The concept was developed and implemented in collaboration with SolarNext AG from Bernau.

(H)ice(s)-cold cooling is the approach

Instead of using electrically driven compression chillers with relatively high power requirements and F-gases as refrigerants, as is often the case, this project mainly uses thermally driven absorption chillers that work with the natural refrigerant water. Waste heat is used as drive energy, which is available in summer from the waste-to-energy plant also operated by Stadtwerke Rosenheim. This makes better use of available heat. The cooling network has the potential to cover the entire city center of Rosenheim in the future.

Energy efficiency and CO2 savings - not just for Rosenheim

The electricity requirement for the entire absorption refrigeration system (including pumps and recooling plant) is up to 90% lower than for compression refrigeration systems, and CO2 emissions are reduced by around 85% compared to a traditional refrigeration system. A concept which - with appropriate adaptations - can be transferred to other municipal utilities and local authorities. Stadtwerke Rosenheim hopes that this option will be increasingly evaluated in the development of district concepts and integrated solutions, so that in future many other municipalities will be able to cool homes, offices and server rooms (h)ice(s)-cold in hot summer months with this sustainable solution.

Cooling supply is climate-friendly and inexpensive

The supply of cooling is growing in importance, as demand is increasing and cooling can be generated much more efficiently in large central systems than in small systems. This requires the construction of cooling networks that connect the various cooling systems and consumers with each other. In combination with the existing district heating, a combined heat, power and cooling (CHP) system is being created here that can supply the city center with cooling in a very environmentally and climate-friendly, but also inexpensive and reliable way in the long term.

Energy concept 2020 - a prime example of sector coupling

The integration of electricity, heating, cooling and heat storage is a prime example of sector coupling and allows renewable energy from wind and solar power to be used and supplemented very flexibly depending on the situation.

Landshut tax office

The Landshut tax office has been awarded the Bavarian Energy Prize 2020 in the "Initiatives and educational projects" categoryfor its "Energy and environmental management" project. Project manager Willi Forster , together with office manager Elisabeth Fett , was presented with the award by Deputy Prime Minister Hubert Aiwanger at a ceremony at the State Ministry of Economic Affairs, Regional Development and Energy in Munich on October 22, 2020.

It is a great pleasure for Willi Forster that his many years of efforts to consciously use electricity and heat sparingly have helped to initiate an internal energy transition in the Bavarian Finance Administration. The federal government decided on the energy transition in 2011, and in his opinion and that of the head of office, state administrations must set a good example. The Landshut tax office has saved around 50% electricity and over 30% heat per year without any major financial or technical effort. All employees have contributed to this success; junior staff have also been involved in various campaigns, both in the area of energy saving and in the planting of approx.

3,000 square meters of flowering areas in cooperation with the Landshut Landscape Conservation Association. The tax office successfully takes part in the annual "City Cycling" campaign, a photovoltaic system with 83 KWp has been installed on the roof and charging stations for e-mobility are currently being planned.

The "Landshut model" could be applied to all existing state administration buildings in Bavaria. Willi Forster has therefore initiated a series of events with all-day expert discussions at all district governments in Bavaria, which has been successfully carried out by the Institute for Renewable Resources and Energy Transition Carmen e.V. since 2018. In addition to the tax office project, many other aspects of sustainable action in administration are highlighted.

Willi Forster has invested a great deal of personal commitment and passion in the "Landshut model" since 2014, but he says modestly: "As a civil servant of the Free State of Bavaria, I have actually only fulfilled my mandate to use the available resources sparingly."

The energy transition needs supporters

Dr. Arwen Colell

Dr. Arwen Colell was awarded the Bavarian Energy Prize 2020 for her practical dissertation on community energy projects.
This year marks the first time that the Bavarian Energy Prize in the energy research category has been awarded to a social scientist. Arwen Colell is being honored for her doctoral thesis on the social innovative power of citizen-owned energy projects.

At the age of 24, the political scientist founded a cooperative together with like-minded people to bring the electricity grid in her home city of Berlin into the hands of citizens. Drawing on her practical experience with various initiatives, her doctorate at the Technical University of Munich now shows just how much power citizens have to shape the energy transition: with an international comparison of community energy projects in Germany, Scotland and Denmark.

Which social innovations are driving the energy transition? The question of what role citizens play in the energy transition has often focused on material resources - for example, the ability to invest. Social participation has been limited to the question of how acceptance for new technologies can grow. A look at citizen-led projects shows this: Non-material resources are at least as important, sometimes even more important, for the successful implementation of local energy projects. Shared values, knowledge and shared symbols make a significant contribution to the sustainable transformation of the energy system at local level. On the Danish island of Samsø, the population knows that you have to be there for each other when you live out here. Skafning, a Danish word that only exists in the local dialect of the island, means neighborly help and a sense of responsibility. When the entire energy supply was to be converted to 100% renewables within just ten years, a common basis had to be found quickly in order to make infrastructure decisions. As part of the joint project work, the energy transition has now also become part of skafning. The example shows: The energy system is not simply a technical expert topic in these communities, but rather a firmly integrated part of the community.
"Community ownership is crucial to the success of the energy transition," explains Colell and emphasizes: "This is what distinguishes community-owned projects, from the Hebrides to Oldenburg, from the Black Forest to the Kattegat: the ability to link technical infrastructure with community values."

Founder of Battery Dynamics GmbH receives Bavarian Energy Award 2020

Dr. Peter Keil

Munich-based battery researcher and founder Dr. Peter Keil receives the Bavarian Energy Award 2020 in the category "Energy Research - Young Talent Award". He was awarded the prize for his doctoral thesis on the ageing of lithium-ion batteries in electric vehicles, which he wrote as a researcher at the Technical University of Munich.

The jury was impressed by his extensive research, which covered both the operating and stationary phases of an electric vehicle. Dr. Keil developed new analysis methods with which ageing reactions at the positive and negative battery electrodes can be more easily identified and differentiated. His series of measurements enabled him to identify optimal temperature conditions for the lithium-ion batteries during charge-discharge operation and during rest phases. In his doctoral thesis, Dr. Keil shows that regenerative braking does not lead to accelerated battery ageing even at low temperatures. Another focus of his research work is battery charging. Here he provides strategies for optimizing charging in electric vehicles so that battery ageing remains low despite high charging speeds. With his findings, he is helping to ensure that battery management systems can be optimally adjusted to achieve longer battery life in electric vehicles.

"I am particularly pleased that my research results are not gathering dust on bookshelves, but are being taken up by many researchers and developers worldwide," says Dr. Peter Keil, who also draws a link to his current work: "I also regularly use the analysis methods developed in my doctoral thesis in my company to examine the ageing behavior of various batteries in more detail." With his company Battery Dynamics GmbH, founded in 2018, he is now developing special battery test devices to help the industry determine the ageing behavior of their battery systems more quickly and accurately. Battery lifetimes of over 20 years and optimal fast-charging strategies are particularly in demand right now.

Artificial photosynthesis from electrolyzer and bioreactor makes CO2 the raw material for a successful energy transition

Siemens Energy - Evonik

Rheticus is a joint project between Siemens Energy and the specialty chemicals company Evonik that began in 2017. The aim of the cooperation is an efficient and powerful pilot plant that can produce specialty chemicals by coupling electrolysis and fermentation technology - from carbon dioxide (CO2) and water as well as electricity from renewable sources and bacteria. On September 21, Siemens Energy and Evonik commissioned the pilot plant in Marl in the northern Ruhr region, which is funded by the German Federal Ministry of Education and Research (BMBF).

Together with a bioreactor (fermenter) from Evonik, the world's first CO electrolyzer from Siemens Energy forms the technology platform on the basis of which both companies can realize an artificial photosynthesis process. This is structured as follows: In a first step, carbon dioxide and water are converted into carbon monoxide (CO) and hydrogen (H2) using electricity by means of electrolysis. Special microorganisms convert the CO-containing gases into chemicals from the resulting synthesis gas. With electrolysis technology and fermentation technology, Siemens Energy and Evonik are each contributing their core competencies to this form of artificial photosynthesis. Plants do a very similar thing in natural photosynthesis: They use chlorophyll, enzymes and sunlight to produce glucose - a vital and energy-rich nutrient. Another advantage of Rheticus is that the technology helps to reduce carbon dioxide pollution in the atmosphere, as CO2 is used as a raw material.

In summary, the Rheticus project uses electrolysis and fermentation technology to combine electrochemical, chemical and biological steps in such a way that electrical energy is used to turn CO2 and water into usable chemicals such as butanol and hexanol, which are used as raw materials in the food and chemical industries, among others.

"I am not only very happy about the award, but also extremely proud of all the colleagues from Siemens Energy and Evonik involved in the project. The entire team has been doing groundbreaking pioneering work since 2017, based on an apparently simple approach: namely to turn one of the main drivers of global warming - carbon dioxide - into a raw material and catalyst for the energy transition," says Karl-Josef Kuhn, Head of Power2X Research at Siemens Energy.

"The truly trusting and always constructive collaboration in our joint research project has made this success possible," says Thomas Haas, who is responsible for Rheticus at Evonik. He continues: "The innovative technology has the potential to contribute to the success of the energy transition. We use CO2 as a raw material to produce valuable chemicals through artificial photosynthesis and at the same time close the carbon cycle."

The project, which is funded by the BMBF with around 6.3 million euros, will run until 2021 and undoubtedly has the potential to make a decisive contribution to the success of the energy transition.

"The Rheticus project is a prime example of how climate protection and economic opportunities can go hand in hand: Innovative thinking, courage and a spirit of research are the key here. With Rheticus, we are demonstrating how the technology of artificial photosynthesis can contribute to the success of the energy transition. Together with all those involved, I am delighted that the achievements of the Rheticus project for a climate-friendly chemical industry have now been recognized with the Bavarian Energy Award. I join in this recognition and warmly congratulate the project, which is being funded by the BMBF with around 6.3 million euros," said Federal Research Minister Anja Karliczek.

The project will run until 2021 and undoubtedly has the potential to make a decisive contribution to the success of the energy transition.

Bavaria's new Minister of Economic Affairs and Energy Hubert Aiwanger presented the Bavarian Energy Award 2018 at the Germanisches Nationalmuseum on November 15, 2018. We congratulate the main prize winner, ÜZ Mainfranken, and eight category prize winners for outstanding creative achievements in efficient energy generation and use.

ÜZ - Giving renewable energy a value!

ÜZ Mainfranken, Lülsfeld

The most fundamental challenge in converting our fossil energy supply to a decentralized, emission-free energy supply is to synchronize the supply of renewable electricity and energy consumption. It is becoming increasingly important to provide renewable energy for the heating and mobility sectors and to combine it with storage technologies in order to further develop the energy transition in a sustainable manner.

ÜZ Mainfranken is a regional energy cooperative that has been involved in the expansion of renewable electricity generation on a daily basis for many years. The challenge of seeing the electricity transition as an opportunity and pushing for a greenhouse gas-free energy transition has been consistently pursued in recent years according to the motto: "Giving renewable energy a value." ÜZ therefore sees its role as a regional player as ensuring that renewable, emission-free electricity is put to long-term use and thus retains its value. Together with local authorities, it is developing the thermal development of new construction areas; the use of near-surface geothermal energy with geothermal probes for each building plot, the use of heat pumps with combined storage. A customized distribution and tariff system completes the concept. This initiative fulfils the cooperative's mission to establish an optimized, efficient energy solution through joint enterprise. "With ÜZ's all-round carefree package of information, application, test drilling, joint implementation of the heating systems with subsequent multi-year monitoring, building owners receive a sustainable heat supply for decades to come," says Gerd Bock, Managing Director of ÜZ, summarizing the benefits of the project for customers. The system also benefits from the use of surplus solar energy, special tariffs and the connection of storage capacities in the electricity distribution grid.

About ÜZ:

Currently, 160 employees work in the business areas of electricity and fiber optic networks, sales, heating projects and energy services for an area of almost 1,000 km² with around 127,000 inhabitants between the Main and Steigerwald rivers. 6,350 renewable plants feed into the distribution grid, which is over 4,000 km long.

Highly efficient CHP system network with cooling and steam generation

Ponnath DIE MEISTERMETZGER GmbH, Kemnath

The innovative energy network at Ponnath's headquarters in Kemnath i.d. Oberpfalz was awarded the prize. The project demonstrates in an exemplary manner how a highly efficient supply of electricity, heat, steam and freezing cold can be achieved through combined heat, power and cooling in food production.

At the heart of the plant is a natural gas cogeneration unit with an electrical output of almost 1300 kilowatts. The special feature of the energy network is that heat can be extracted very flexibly from this combined heat and power plant at different temperature levels: on the one hand as steam for production and as heat for heating, and on the other hand converted into cold down to -10 °C. This can be used via a specially developed absorption system. This is achieved using a specially developed absorption refrigeration system with an ammonia-water mixture as the working medium, which is driven by the waste heat from the combined heat and power plant and can provide temperatures down to below freezing. In addition, the combined heat and power plant enables emergency power operation so that the plant's supply can be restored within a few minutes in the event of a power failure and the cold chain for the food can be maintained.
With overall efficiency levels of up to 95%, the system is highly efficient. Compared to the state of the art, this results in primary energy savings of around 30%, which corresponds to a reduction in CO2 emissions of around 1800 tons per year.
"With the energy network, we are making the energy supply of our main plant fit for the future and taking our responsibility for the resource-saving use of energy seriously," says Managing Director Michael Ponnath.

Ponnath DIE MEISTERMETZGER - tradition since 1692
Ponnath DIE MEISTERMETZGER is one of the most modern and important German manufacturers of sausage, ham and aspic specialties and produces at six specialized locations in Germany and Bohemia.
Now in its twelfth generation, the family business is still managed by the founding family itself, making it the oldest family-run company in the butcher's trade in Germany. The company headquarters in Kemnath, Upper Palatinate, specializes in the production of cooked sausage and sausages.

LINDA - Local island grid supply and accelerated grid restoration with decentralized generation plants in the event of large-scale power outages

LEW Verteilnetz GmbH, Augsburg, and project partners

LINDA project awarded Bavarian Energy Prize:
LEW Verteilnetz and partners have developed a concept for emergency power supply with decentralized generation plants - establishment of a stable stand-alone grid with renewable energies

The LINDA project (local island grid supply and accelerated grid restoration with decentralized generation plants in the event of large-scale power outages) has won the Bavarian Energy Award 2018 in the category "Energy generation - electricity, heat". The concept of LEW Verteilnetz GmbH (LVN) and its project partners from industry and science opens up decentralized power generation plants from renewable energies for the emergency power supply of critical infrastructures. LVN is donating the prize money of €2,000 in equal parts to Augsburg University of Applied Sciences and the Technical University of Munich.

"We designed and implemented the LINDA project in close and good cooperation with Augsburg University of Applied Sciences and the Technical University of Munich," says LEW Board Member Dr. Markus Litpher. "It is an example of successful cooperation between business and science. Everyone has contributed their strengths to create real added value together. The findings from the project will take us another step forward on the road to the energy future."

Securing the emergency power supply with renewables

Background to the project: A prolonged, widespread power outage can have serious consequences in our modern society. In the LINDA project, LEW Verteilnetz GmbH (LVN) and its project partners from industry and science have proven that decentralized generation plants, such as photovoltaic systems, hydroelectric power plants or biogas plants, can be used for emergency power supply in the event of a blackout. The project partners have developed a concept for this and successfully tested it in practice in the most extensive stand-alone grid trials in Germany to date: In up to three municipalities, up to 1,100 households, 185 photovoltaic systems as well as two hydropower plants and a biogas plant were integrated into a self-sufficient stand-alone grid. "Stable stand-alone grid operation was possible at all times during the field tests," says Dr. Georg Kerber, project manager at LVN. "The aim now is to further develop the LINDA concept in order to integrate it into emergency concepts and grid restoration plans.

Power-to-gas in practice

Stadtwerk Haßfurt GmbH and Greenpeace Energy eG, Hamburg

A look into the future of energy:
Bavarian Energy Award for power-to-gas plant in Hassfurt

Haßfurt, 15.11.2018 - Windgas Haßfurt GmbH has been awarded the Bavarian Energy Prize in the "Energy distribution and storage" category for its practical use of pioneering power-to-gas technology. The award recognizes the knowledge that the joint venture between Städtische Betriebe Haßfurt GmbH and the Hamburg-based green energy cooperative Greenpeace Energy is gathering for the storage of renewable energy. "We are delighted to receive this award," says Nils Müller, CEO of Greenpeace Energy, "it honors a technology that is indispensable for a successful energy transition."
Since October 2016, an electrolyser in Hassfurt has been converting surplus energy from renewable power plants in the municipal power grid into environmentally friendly hydrogen. This so-called "wind gas" is fed into the gas grid for proWindgas customers of Greenpeace Energy.
The more electricity is generated from wind and solar power plants in the future as part of the energy transition, the greater the resulting electricity surpluses will be. These can be fed into the gas grid in large quantities as wind gas, where they can be stored over long periods of time and converted back into electricity when needed. In this way, phases of up to three months without wind and sunshine can be bridged. Only wind gas technology, which uses the existing gas grid including underground storage facilities, offers the necessary storage capacity. "Windgas makes the energy transition secure even with 100% renewables," emphasizes Nils Müller.
The fast-reacting 1.25 MW electrolyser of the latest generation from Siemens also stabilizes the power grid, where generation and consumption must always be in balance. To do this, it increases or decreases its output within seconds in order to compensate for frequency fluctuations in the grid and thus prevent blackouts, for example.

 

With "Windgas Haßfurt GmbH & Co. KG", the municipal supplier and the nationwide green energy provider are also testing how high the proportion of hydrogen in the gas grid can be. A nearby malthouse is taking part in the test, generating electricity and heat with part of the gas mixture in its CHP units. "We are doing pioneering work here in Haßfurt," says Norbert Zösch, Managing Director of Städtische Betriebe Haßfurt GmbH. "Without the commitment of local authorities, the energy transition will hardly be successful. We hope our example will find many imitators."

e% - Energy-efficient residential construction in Ansbach

Joseph Foundation Bamberg, Deppisch Architects and Engineering Office M. Vogt, Freising

Energy-efficient and affordable living space in Ansbach

The church housing company Joseph-Stiftung from Bamberg has received the Bavarian Energy Award 2018 in the "Buildings" category for its rental housing complex in Herbartstraße in Ansbach, which was built in 2013 using timber construction.
The multi-award-winning ensemble offers high energy efficiency and quality of life with affordable rents.
"We are delighted that our residential complex in Ansbach has received the Bavarian Energy Award 2018. This award shows that high energy efficiency, affordable costs and special qualities of use can be combined very well," says Technical Director Reinhard Zingler.
The project was developed as part of the "e% - energy-efficient residential construction" model project of the Bavarian State Ministry of the Interior, Building and Transport's Supreme Building Authority. The aim was to find energy-efficient, contemporary and cost-optimized solutions with high architectural and urban planning standards. The Joseph Foundation (client) achieved this in close cooperation with the architectural firm Deppisch and the engineering firm Vogt (supply technology), both from Freising. The 37 residential units of the barrier-free residential complex are subsidized according to income.

The typology of the four-sided courtyard forms a quiet, semi-public square with the building entrances. Functions such as building services, bicycle and drying rooms are located around this inner courtyard. This made it possible to dispense with the construction of basement levels and at the same time promote neighborly interaction.

The compact structures were built using a simple timber frame construction with an optimized proportion of windows, thus achieving very good energy efficiency values during construction and operation. The interior stairwells, which are naturally lit via domed ceilings, are unheated and allow for different apartment layouts, each oriented to two sides.
Easy-to-operate systems such as the exhaust air system with overflow openings in the windows, heat supply via the central pellet heating system and photovoltaics for the general electricity supply contribute to the sustainability of the residential complex as robust and durable elements.

The Joseph Foundation was founded in 1948 as a church housing company by the then Archbishop of Bamberg. It is committed to fundamental Christian values. The purpose of the foundation is to improve housing provision in an appropriate and socially acceptable way. The company pursues a sustainable business model and is active in the areas of construction and construction management, property development and real estate management. The company's own housing portfolio comprises around 5,500 residential units in the Nuremberg metropolitan region and the Regensburg and Dresden conurbations.

Berchtesgadener Land energy utilization plan

District of Berchtesgadener Land, Bad Reichenhall

The district of Berchtesgadener Land has been awarded the Bavarian Energy Prize 2018 in the "Municipal Energy Concepts" category for the Berchtesgadener Land Energy Use Plan.

Together with all of the district's municipalities, the district of Berchtesgadener Land is committed to sustainable economic development and has been working consistently for years to implement its ambitious climate protection goals.

The Berchtesgadener Land energy utilization plan is the central instrument for the implementation of energy-saving measures and the development of a sustainable local energy supply. Where can heat be saved and in which areas is a heating network worthwhile? Which roofs are suitable for the use of solar energy and at which locations are there opportunities to expand hydropower? In order to find answers to these questions, the district, together with all the towns, markets and municipalities, developed an innovative tool in the form of the energy use plan, which sets new standards throughout Bavaria with its level of detail thanks to the building-specific energy model.

"We are all pulling together here," says District Administrator Georg Grabner with regard to the cooperation with the municipalities and clarifies: "One year after completion of the project, more than 30 projects from the energy use plan with a total project volume of several million euros are already being planned or implemented."

The energy use plan is not only aimed at local authorities, but also at private homeowners and commercial enterprises in the district. "With the building-specific information, we can support anyone who is planning an energy-efficient renovation or would like to use renewable energies for their own building," emphasizes Climate Protection Manager Manuel Münch.

The KEiM (Keep Energy in Mind) energy-saving program at Nuremberg schools

Building Construction Office of the City of Nuremberg / Municipal Energy Management and Institute for Education and School Psychology / Nuremberg Environmental Station

The KEiM (Keep Energy in Mind) energy-saving program has been taking place at Nuremberg schools for over 18 years. It has become an integral part of the city of Nuremberg's climate protection activities. Now it has been awarded the Bavarian Energy Prize 2018 in the "Initiatives/Educational Projects" category. Dr. Christian Büttner from the Institute of Education and School Psychology emphasized at the award ceremony: "The KEiM projects of the Nuremberg schools clearly show that everyone can make a contribution to climate protection, from an early age." "And it can even be a lot of fun," adds Rainer Knaupp from Municipal Energy Management.

The KEiM program, initiated in 1999, involves close cooperation between the Nuremberg Environmental Station, affiliated with the Institute for Education and School Psychology, and the Municipal Energy Management - part of the Building Construction Office. Thanks to the involvement of two municipal institutions, the program receives a great deal of support from the city administration.

The aim of the program is to sensitize schoolchildren of all ages to saving electricity, heating energy and water. An important part of the program is the annual energy-saving competition. All Nuremberg schools can submit a project for this. These projects range from calendars with energy-saving tips to theater plays or film clips on the subject to entire "electricity-free" project days. The introduction of energy sheriffs can also have a particularly strong impact on children and has a major effect on energy savings: Among other things, this involves pupils systematically making sure that lights are switched off when not needed, that ventilation is only provided by shocks and not by tilting, and that no appliances are in stand-by mode. Towards the end of the school year, a jury evaluates all submitted projects. Prize money of up to 2,500 euros is up for grabs.

The energy-saving projects are initiated at the schools by the KEiM teachers. They integrate the topic of energy saving into lessons and school life and bring the program to life with their pupils.

These efforts by Nuremberg's schools lead to average savings of around 1,750 tons of CO2 per year - a great result for climate protection in the city of Nuremberg.

Company portrait:

Municipal Energy Management is part of the City of Nuremberg's Building Department. It is responsible for the energy controlling of all municipal properties, carries out optimization measures, accompanies the energy and building physics quality assurance for new construction projects and renovation measures, supports the installation of renewable energies and holds seminars on current topics in the energy sector, for example. With twelve employees, all areas of technical building services and building physics are covered on an interdisciplinary basis.

Chamber of Industry and Commerce for Munich and Upper Bavaria

Minister of Economic Affairs recognizes successful qualification project for trainees

Munich - Since 2014, around 250 trainees have acted as "energy scouts" in their Upper Bavarian training companies to promote the more economical use of resources. Yesterday, the Chamber of Industry and Commerce for Munich and Upper Bavaria received the Bavarian Energy Award in the Education Projects category in Nuremberg.

In the project, the IHK for Munich and Upper Bavaria trains trainees to become "energy scouts" who systematically look for, calculate, implement and document potential savings in the company. This saves the companies hard cash. The trainees also get to know their company better and gain valuable experience in teamwork and project management. "Energy Scouts" have already successfully completed projects in almost 100 companies in Upper Bavaria. Most of these projects involve more efficient and economical lighting, heating and compressed air systems, pumps or refrigeration technology. However, employee handbooks on saving energy or the installation of solar cells are also among the project results. The participating companies range from small and medium-sized enterprises to large corporations. Practically all sectors are represented, from industrial companies to retailers and restaurants.

The "Energy Scouts" project was developed by the IHKs in Germany as part of the nationwide SME initiative for energy transition and climate protection and was funded by the Federal Ministry of Economics and the Federal Ministry for the Environment during the pilot phase. This was so successful in Upper Bavaria that the companies themselves have been financing the trainees' qualification courses at the IHK Academy since 2016. Other Bavarian IHKs now also offer energy scout training courses as part of their program.

Dr.-Ing. Florian Samweber, Technical University of Munich

PhD entitled: Systematic comparison of grid-optimizing measures for integrating electric heat generators and vehicles into low-voltage grids

Bavaria has played a leading role worldwide in the field of innovative mobility and heat supply for many decades. Zero (local) emissions are currently at the center of political debate and are the goal of international agreements. In order to maintain a leading position in the future, the electricity grid infrastructure in Bavaria must be prepared for the electrification of mobility (see Figure 2) and space heating.

Florian Samweber has developed and applied a method that makes it possible to compare innovative approaches to grid optimization from a holistic perspective. This allows potential grid bottlenecks to be reduced at an early stage. The central motivation of his dissertation is a systematic comparison of grid-optimizing measures for integrating electric heat generators and vehicles into low-voltage grids.

A holistic evaluation of grid-optimizing measures requires a highly specialized simulation model with individual parameterization of all available grid-optimizing measures. With the "GridSim" simulation model, which was further developed as part of the work, it is possible to carry out various evaluations of individual assessment dimensions.
The constant exchange with various distribution grid operators ensures a high level of practical relevance in the work. In addition to the informal exchange, the use of real grid data can also be mentioned in particular.

The grid-optimizing measures "conventional grid expansion", "longitudinal controllers" and "controllable local grid transformers" perform best in the analysis of the technical evaluation dimensions in a large number of type grids. While grid-oriented measures can contribute in particular to the integration of photovoltaic generation into the energy system, from a technical point of view they are only suitable to a very limited extent for reducing the need for grid expansion resulting from increasing electrification.

The dissertation was only possible in its final form through the use of the findings from the "MONA 2030" project led by Mr. Samweber (see also www.ffe.de/mona). This was funded by the Federal Ministry for Economic Affairs and Energy and supported financially and in terms of content by 16 grid operators, energy suppliers and an automobile manufacturer. In the MONA project, a large number of scientific staff and students worked on the detailed evaluation of electricity grids.
