Sunfire GmbH has delivered a steam electrolysis moduel to Salzgitter Flachstahl GmbH, in the context of the Horizon 2020 project ‘Green Industrial Hydrogen via reversible high-temperature electrolysis’ (GrInHy).
With an input power of 150 kWel the module produces 40 Nm3 per hour of hydrogen (H2). It can also be reversed into fuel cell mode with an output power of 30 kWel.
A particular feature of Sunfire technology is the high electrical efficiency of more than 80% with reference to the lower calorific value of H2. The steam required is provided in the form of waste heat from the processes of the smelting plant at Salzgitter Flachstahl and supplied to the steam electrolysis unit.
