In a joint paper, the four Kopernikus projects—Ariadne, ENSURE, P2X, and SynErgie—show how research and technology can support climate neutrality by 2045.

According to the four Kopernikus projects—Ariadne, ENSURE, P2X, and SynErgie—Germany’s energy transition can lead to climate neutrality by 2045. Prerequisites for this include the accelerated expansion of renewable energy, the electrification of applications, a high-performance infrastructure, greater flexibility on the demand side, and the targeted use of CO2-free molecules. The projects reached this conclusion in a joint brief that synthesizes research findings from approximately ten years of energy transition research.

The Kopernikus projects are funded by the Federal Ministry of Research and examine various aspects of the energy system’s transformation. While the Ariadne project primarily analyzes macroeconomic and political transformation pathways, Ensure focuses on energy infrastructure, Synergie on industrial flexibility, and P2X on the production of synthetic energy carriers.

Three Elements for Cost Efficiency

According to the researchers, three elements form the basis for cost-effective climate neutrality: the decarbonization of electricity generation, the electrification of end-use sectors, and the use of green molecules in areas that cannot be directly electrified. These include, in particular, certain sectors of industry as well as air and maritime transportation.

Accordingly, the expansion of renewable energy remains the central prerequisite for the transformation. At the same time, the integration of additional electricity must be supported by the expansion of transmission and distribution grids, as well as through storage and Power-to-X facilities.

Rethinking Infrastructure

The Kopernikus Ensure project highlights the importance of innovative infrastructure planning in the paper. According to the researchers, a method was developed, among other things, that allows for the joint planning of electricity, natural gas, and hydrogen networks. This would optimize the use of power-to-gas plants and enable a more accurate assessment of future infrastructure needs.

In addition, Ensure examined the future role of various technologies in district heating. According to the project, both combined heat and power plants using climate-neutral fuels and large-scale heat pumps play an important role in decarbonized heating networks. To test new technologies in realistic simulation environments before their deployment, the researchers developed a so-called co-demonstration platform on which the grid compatibility and system impacts of new solutions can be assessed.

Industry Can Become More Flexible

The Synergie project sees significant potential for greater flexibility on the demand side. According to a survey of 31 companies, relevant options for load shifting are already available today. The companies reported flexibility potential of 1.7 billion kWh per year for load increase and 3.5 billion kWh per year for load reduction.

This potential could grow significantly by 2045. The researchers estimate that the increasing electrification of industrial process heat and the use of so-called bivalent technologies could increase flexibility to up to 25 billion kWh per year. However, this would require corresponding grid expansion and an appropriate regulatory framework.

Procuring Green Molecules

The P2X project focuses on supplying applications that cannot be electrified. The researchers analyzed production facilities for synthetic kerosene, methanol, and ammonia in Germany, Chile, and South Africa. Their analysis revealed that production costs do not depend solely on the availability of renewable energy.

According to the study, the costs of hydrogen and the investment risk, in particular, influence economic viability. To scale up the production of green molecules to the required extent, the project estimates that international sustainability standards and uniform regulatory guidelines are necessary. Only then can global markets for Power-to-X products emerge and investment security be established.

Synergy Enables Climate Neutrality

In the authors’ view, synthesizing the various research findings demonstrates that climate neutrality cannot be achieved through individual technologies alone. The pace of emissions reduction must nearly double compared to previous decades. Therefore, the synergy between renewable electricity generation, grid infrastructure, flexibility, sector coupling, and climate-neutral energy sources is crucial.
