A new scientific journal article demonstrates how combining diverse renewable energy sources and locations can significantly reduce costs of producing green hydrogen under temporal matching requirements.

It is still unclear exactly how much hydrogen will be needed in the future. However, the planned core network could supply the load centers in most demand scenarios of existing energy system studies, according to a recent analysis by the EWI.

Together with the Forum for Future Energies, the EWI organized the first “Berlin Science Talk on the Energy Industry”. In keynote speeches and a panel discussion, experts addressed the question “How are electricity prices developing?”

The operation of renewable energy plants is subsidized in Germany. As part of the EEG medium-term forecast, the EWI examines how much renewable electricity can be expected in the coming years – and how much its funding could cost.

Low-carbon hydrogen plays a central role in German climate neutrality scenarios. However, the EWI shows that the currently projected costs could lead to a theoretical financing gap of several billion euros.

The latest edition of the EWI Insights series focused on the most economical heating solution in a climate-neutral energy system and the costs of distribution network infrastructures for heat supply.

Hydrogen storage is intended to contribute to the energy supply in the future. On behalf of RWE Gas Storage West, the Institute of Energy Economics has analyzed how high the storage requirements could be in Germany and Europe by 2050.

The cost of hydrogen imports is influenced by financing and transportation options. Hydrogen storage also plays a crucial role in a climate-neutral energy system. This was the subject of the latest EWI-Insights.

System-serving electrolysers can support the energy system and save costs as well as resources. An EWI report shows that such electrolysers could be located in all parts of Germany.
