Sunfire Delivers the Worlds Largest High Temperature Electrolyser to Salzgitter Flachstahl

Sunfire has now delivered the world’s most powerful high-temperature electrolyser (HTE) for energy-efficient hydrogen generation to Salzgitter Flachstahl GmbH.

As part of the GrInHy2.0 project, high-temperature electrolysis with a nominal electrical output of 720 kilowatts is being used in an industrial environment for the first time. GrInHy2.0 is a further step of Salzgitter AG towards a CO 2 low-carbon steel production in the innovation project SALCOS® – SA lzgitter L ow CO 2 – S teelmaking. By the end of 2022, the electrolyser should be in operation for at least 13,000 hours and produce at least 100 tons of green hydrogen from green electricity.

“In the course of the recently adopted hydrogen strategies of the European Union and Germany, the necessity of large-scale electrolysers for steel production has also been made clear by politicians. Green steel requires green hydrogen and GrInHy2.0 shows the great potential of the energy carrier for energy-intensive industries. New and low-CO 2 production routes are currently being developed intensively in the steel industry . We look forward to being part of it together with our partners. The technology is ready for the production of hydrogen on an industrial scale and we are ready to significantly increase our production capacity for this ”, says Nils Aldag, Managing Director, Sunfire GmbH.

As a pioneer, Salzgitter Flachstahl GmbH and Sunfire started the GrInHy project back in 2016. In cooperation with the partners Paul Wurth SA, Tenova SpA, the French research center CEA and Salzgitter Mannesmann Forschung GmbH, GrInHy2.0 is now seamlessly linked to the successful first project.

Dr. Benedikt Ritterbach, Managing Director of Salzgitter Mannesmann Forschung GmbH and responsible for research and development in the Salzgitter Group: “Green hydrogen is a central component on our path towards CO 2-poor steel production. With the integration of this world’s most powerful system into large-scale industrial processes, we are breaking new ground in energy-efficient hydrogen generation. GrInHy2.0 will provide us with further information on the industrial demonstration operation of a high-temperature electrolyser. ”

The project is funded by the Fuel Cells and Hydrogen 2 Joint Undertaking (JU) under grant agreement No. 826350. The JU receives support from the European Union’s Horizon 2020 research and innovation program, Hydrogen Europe and Hydrogen Europe Research.

About Sunfire
Sunfire GmbH, founded in 2010, develops and produces high-temperature electrolysers (SOEC) and high-temperature fuel cells based on solid oxide technology (SOFC). The company employs more than 170 people and is the world leader in commercial SOEC. High-temperature electrolysis generates valuable hydrogen from steam and renewable energy. The use of steam instead of liquid water in the electrolysis increases the efficiency of the process considerably and is particularly suitable for industrial applications in which process heat is available. The technology promises to make the entire transport sector and many industrial processes that today depend on oil, gas or coal sustainable and CO 2-to make neutral. More information at:  www.sunfire.de
