Energy storage systems – research for the energy transition

With the continuously rising share of renewable energies in the energy supply system, storage systems for electrical and thermal energy are becoming ever more important. If electricity is converted before it is stored, for example into hydrogen or other chemical energy sources, this energy can then be used in other energy industry-related sectors and thus for the much-needed coupling of the various sectors, all in addition to re-electrification of stored energy.

To date, however, only few storage technologies have reached the necessary technical maturity at a competitive cost level. The Federal Ministry for Economic Affairs and Energy and the Federal Ministry of Education and Research have recognised the research and development needs in the area of energy storage technology and are developing tailored promotional activities as part of the 6th Energy Research Programme of the Federal Government. With the Energy Storage Funding Initiative, both ministries have been supporting innovations for a wide range of storage technologies since 2011. But development is ongoing: the two ministries are pursuing new storage concepts and are further advancing existing technological developments also beyond the Energy Storage Funding Initiative.
