Founded in 2010, Sunfire GmbH develops, produces and operates steam-electrolysers (SOEC) and high-temperature fuel cells (SOFC).


Steam-electrolysers split steam into hydrogen and oxygen using renewable electricity. The resulting hydrogen can be used for hydrogen mobility and in industrial applications without any further processing. Additionally, Sunfire owns proprietory knowhow in the conversion of hydrogen and carbon dioxide to e-Fuels and e-Gas.


High-temperature fuel cells from Sunfire can be used to produce power and heat particularly efficiently based on cogeneration. Decentral cogeneration at the lower end of the power output range is seen as an energy concept of the future as it allows power and heat to be generated on demand exactly where it is needed.
