The aim of the research cluster "High Temperature Co-Electrolysis for Synthesis Gas Generation" (FC-A3) is the conversion of carbon dioxide and water vapor with electricity from renewable energy sources to synthesis gas (power-to-syngas). The research and development of co-electrolysis technology in transient operation will provide tailor-made synthesis gas compositions for the subsequent production of fuels and industrial raw materials.

The big advantage of high-temperature co-electrolysis is the possibility to produce tailor-made synthesis gas compositions without downstream process steps. In addition, the high-temperature electrolysis has a comparatively low energy consumption. In the case that the heat demand can be covered by waste heat from upstream or downstream processes, the efficiency of the co-electrolysis process even increases to values greater than 100%.
