According to Salzgitter, the electrolyzer has a rated electrical output of 720 kW and is expected to have produced at least 100 tons of green hydrogen from renewable electricity by the end of 2022. 

The new equipment is part of the GrInHy2.0 project, which aims to develop a carbon-neutral, hydrogen-based steelmaking process.

The effort brings together Salzgitter, hydrogen electrolyzer manufacturer Sunfire, which built the Salzgitter electrolyzer, and steel industry partners Paul Wurth S.A. and Tenova SpA. 

“Green steel requires green hydrogen and the implementation of GrInHy2.0 showcases the great potential of this energy carrier for energy-intensive industries,” Nils Aldag, managing director of Sunfire GmbH, said in a statement.
