About Sunfire

Published on 19 June 2020

​Sunfire GmbH, founded in 2010, develops and produces high-temperature electrolysers (SOEC) and high-temperature fuel cells based on solid oxide cell technology (SOFC). The company employs more than 170 people and is the world market leader for commercial SOEC. High-temperature electrolysis generates valuable hydrogen from steam powered by renewable electricity. The use of steam instead of liquid water for electrolysis significantly increases the efficiency of the process and is specifically well suited for industrial application where process heat is available. The technology holds promise to make the entire transport sector and many industrial processes, which today depend on oil, gas or coal, sustainable and CO2-neutral. Further information at
