Salzgitter has announced a record efficiency for its GrInHy2.0 hydrogen project, which is funded by the European Union. The German steel producer said the project has demonstrated “the world's largest high-temperature electrolyzer,” manufactured by German electrolysis specialist Sunfire. Based on solid oxide electrolysis cell (SOEC) technology, the electrolyzer runs at an operating temperature of 850 C and uses waste heat from Salzgitter's steel production processes. “For the first time, the electrolyzer produced 200 Nm3 of green hydrogen per hour. We are also able to prove an electrical efficiency of 84% el,LHV. This is a level of efficiency that no one else has achieved before. By comparison, other electrolysis technologies, such as Alkaline or PEM, only reach efficiencies of around 60% el,LHV,” said Simon Kroop, a project leader for Salzgitter Mannesmann Forschung.
