Chemical Energy Storage

Against the background of an increasing interconnection of different fields, the conversion of electrical energy into chemical energy plays an important role. For example, Fraunhofer’s researchers are working on relevant power-to-gas procedures, which make it possible to chemically store energy in form of hydrogen or methane.

Power-to-X (including gas)

In view of the increasing sector coupling, concepts for the storage or conversion of energy into other forms of energy become necessary. Power-to-gas technologies can be used to implement long-term storage of renewable energies in the form of hydrogen (through water electrolysis) or methane. Hydrogen has a high energy density and offers possibilities for emission-free energy supply. For example, Fraunhofer researchers have realized a solar-powered hydrogen filling station as a reference project for emission-free mobility. In further projects, concepts for the methanation of wind-H2 and biogas-CO2 including co-electrolysis are being investigated and validated. Power-to-X technologies can also be used to produce chemicals for further material use. For example, Fraunhofer scientists have been working on the electrochemical production of hydrogen peroxide as part of the Fraunhofer lead project "Electricity as a raw material". In further projects, for example, continuous electrochemical processes for obtaining oligo- and polymers from lignin degradation products are investigated.
