Salzgitter Flachstahl receives “world’s most powerful” electrolyser

The “world’s most powerful” high-temperature electrolyser has been delivered to Salzgitter Flachstahl GmbH to assist with energy-efficient hydrogen production.

Operating as part of the GrInHy2.0 project, Sunfire’s electrolyser which boasts an electrical output of 720kw will be operational for approximately 13,000 hours by the end of 2022, producing at least 100 tonnes of green hydrogen from renewable electricity.

GrInHy2.0 is another step by Salzgitter AG towards low CO2 steel production within the framework of the innovation project SALCOS® – Salzgitter Low CO2 Steelmaking.
