The Hydrogen Days kicked off on 1.12.2025 with the specialist event Hydrogen Technologies & Innovations - Bavaria & UKwhich was held in close cooperation with the Zentrum Wasserstoff.Bayern (H2.B).

• Infrastructure as a basic prerequisite: Professor Ulmer from Nuremberg Institute of Technology emphasized the need for large-scale hydrogen infrastructure - from pipelines and filling stations to system integration - especially for hydrogen mobility and heavy road freight transport. The "RealEnergy" project at the Ohm Innovation Center (OIC) at Nuremberg Tech serves as a central real-world laboratory for researching and demonstrating regional H₂ production, storage and use.
• Regional H₂ ecosystems: Dr. Rudi Kaiser and Ralph Troppmann (Robert Bosch GmbH) illustrated the Bosch concept of the "Hydrogen Landscape" using the example of Bamberg, where local generation, storage and test environments are combined with the real operation of the Nuremberg H₂ truck to create a cohesive ecosystem. This interaction demonstrates practical solutions for climate-friendly heavy goods transport along the entire value chain.
• Storage and transportation solutions: Professor Weihrich (University of Augsburg) presented insights into various storage and transportation options such as compressed hydrogen and modular container systems. These technologies are essential for enabling commercial and long-distance H₂ mobility and their flexible integration into existing logistics chains.
• Visit to Hydrogenious (Erlangen): A key highlight was the visit to Hydrogenious, the world's leading technology pioneer for LOHC technology (Liquid Organic Hydrogen Carriers).

The second day was all about research and mobility - with practical insights into innovative hydrogen technologies and their application in industry and vehicle development.

• Visit to ostermeier H2ydrogen Solutions: at OHS, the focus was on local, scalable H₂ systems for electricity, heat and mobility, which are particularly attractive for British companies that require turnkey solutions.
• Research collaborations at TUM offered a comprehensive insight into hydrogen research - from high-temperature fuel cells and test infrastructures (H₂ Living Lab Burghausen) to lightweight fiber composite pressure vessels and the Cryo-Truck project for cryogenic hydrogen logistics in heavy goods transport.
• BMW hydrogen competence center (Garching): At BMW, the participants were given an exclusive insight into the prototype development of the BMW iX5 Hydrogen, which is scheduled to go into series production in 2028. Technological highlight: the iX5 Hydrogen uses a modular vehicle architecture (CLAR platform) that allows both battery electric and fuel cell drives to be realized on the same basis. The electric powertrain is combined with an integrated fuel cell system and H₂ tanks

The final day in Augsburg offered a compact overview of the Innovation Park and the Technology Center Augsburg (TZA) as a platform for technology companies and research.

• Drive technology and integration: The hardware-in-the-loop project for a hydrogen-cooled axial flux motor was presented at the TZA Gersthofen, showing how highly integrated electric motors and hydrogen technology are growing together in drive technology.
• Sustainable power and maritime solutions: Rolls-Royce Solutions presented solutions for critical applications in energy, industry and mobility under the motto "Sustainable power that matters". Under "Moving Big Things to Zero", Everllence showed how heavy-duty applications and large systems, particularly in shipping, can be decarbonized using hydrogen and power-to-X technologies.
• H₂ regional transport you can touch: A visit to the Bayerische Regiobahn maintenance plant in Augsburg and the Mireo Plus H hydrogen test train. Participants received a technical introduction to the fuel cell system, hydrogen tanks and application profiles, experienced refueling at the H₂ filling station and a special trip to Augsburg Central Station.
