Energy source of the future

Innovative technology with a wide range of applications

Everyone is talking about hydrogen – produced in a climate-friendly way, hydrogen can help reduce CO2 emissions in industry or the transport sector. For example. As an innovative technology, there are various possible uses: as a raw material for industrial processes (e.g. ammonia and steel), in generating power with very high shares of wind and solar power, and in the production of alternative aviation fuels.

How does hydrogen fit into the overall picture, and how can it contribute to achieving climate goals? What does a regulatory framework, which makes sensible use of hydrogen’s potential, look like? There are still many open questions. Here, Ariadne provides an overview of the potential role of hydrogen for the energy transition. From the supply potential of green hydrogen to the costs, from useful fields of application to uncertainties and risks, from the security strategy for hydrogen imports to necessary infrastructure.

Get started despite uncertainties – cornerstones of an adaptable hydrogen strategy

Green hydrogen and e-fuels are undoubtedly necessary for Germany’s path towards climate neutrality in 2045. However, unlike renewable electricity from wind and solar, we have not yet made any practical use of these energy sources. Therefore, the debate is still based on very different estimates as to when and what quantities of hydrogen will be available, and at what prices. In new Ariadne paper experts from six institutes now present key points for an adaptable hydrogen strategy.
