In the form of a study the theoretical conditions for the testing of an integrated overall system "Renewable energy - Hydrogen - Large-scale storage - Use" are investigated in industrial relevant dimensions. For this purpose, water electrolysers as a key technology are investigated in order to identify possible technological risks in the implementation and assessment of these systems. This work will be complemented by work in the field of salt cavern storage and analysis of existing salt caverns as well as accompanying studies on the potential and technological requirements of the electricity supply from renewable energy sources. This serves as the basis for a chemical storage of renewable energy to compensate for the fluctuating yields and thus provides a basis for the availability of hydrogen as an energy carrier and fuel of the future.
Within sub-project 5, we carry out an evaluation of central versus decentralized hydrogen production in Germany. Subject of this sub-project is a study of various options and applications for production and use of renewable hydrogen with an energy system model in order to derive statements about the integration and utilization of technologies (full load), costs, etc., in various scenarios. Germany is modelled embedded in a European energy system in order to take into account effects of a long-distance electricity transmission and exchange within the European electricity network.
