The GrInHy2.0 high-temperature electrolyser is the largest of its kind in the world. At the end of 2020, it was successfully tested in an industrial environment for the first time. Bart Biebuyck, Executive Director of the EU funding agency “Fuel Cells and Hydrogen Joint Undertaking”, visited Salzgitter on July 14, 2021 to find out more about the GrInHy2.0 electrolyser and the current project status. GrInHy2.0 started in 2019 as a follow-up project to the successfully completed GrInHy project, Green Industrial Hydrogen. With green hydrogen, produced by steam from waste heat sources and renewable electricity using high-temperature electrolysis, steel can be produced without CO 2 in the long term Emissions are produced. The project is part of the future decarbonisation of the steel industry. Members of the consortium are the project partners Salzgitter Flachstahl, Salzgitter Mannesmann Research, Sunfire, Paul Wurth, Tenova and the French research institute CEA. The Dresden electrolysis company Sunfire developed and produced the high-temperature electrolyser. Based on the innovative solid oxide cell technology, the system uses waste heat that is already available from industry and runs at a temperature of 850 degree C. This makes the electrolyser considerably more efficient than other technologies available on the market - it requires significantly less electricity to produce one kilogram of green hydrogen.The GrInHy2.0 electrolyser is part of the SALCOS transformation project to CO 2- poor steel manufacturing. A large part of the infrastructure required for the installation of the electrolysis system was already in place, from the waste heat to the hydrogen pipeline and the green electricity supply. In December 2020, the electrolyser successfully produced hydrogen for the first time, a major milestone in the project. Since then, the green hydrogen has been fed directly into the hydrogen gas network of the steelworks. As of now, 15 tons of green hydrogen have already been used in the annealing processes and galvanizing plants of SZFG for steel refinement.
