GrInHy2.0 - Green Industrial Hydrogen
As part of the "GrInHy2.0" project, Salzgitter AG and its partners are building and operating the world's largest high-temperature electrolyser. By the end of 2022, the electrolyser is expected to produce around 100 tonnes of hydrogen. Together with other sub-projects, the project is expected to make a significant contribution to reducing emissions in steel production.
News (15.12.2023): Research cooperation between Salzgitter AG and Sunfire GmbH enters third round
As part of the "Green Industrial Hydrogen" (GrInHy) research cooperation, the industrial use of high-temperature electrolysis in steel production is being investigated in more detail in Salzgitter. In the GrInHy2.0 project, a SOEC electrolyzer has already been built which, according to Salzgitter AG, has achieved a record efficiency of 84%.
After more than 19,00 operating hours and 190 tons of hydrogen produced, two new test modules with an electrolysis capacity of 540 kW are now being integrated into the existing infrastructure as part of the follow-up project "GrInHy3.0". These are even more robust and efficient, meaning that the plant will produce around 16.5 kilograms of hydrogen per hour in future. The hydrogen produced will be used, among other things, for the direct reduction of iron ore in Salzgitter AG's µDral test plant. Commissioning of the new modules is scheduled for 2024.
The project, which will run until 2027, is being implemented together with the TU Bergakademie Freiberg and is funded by the Federal Ministry for Economic Affairs and Climate Protection. Read more
In the GrInHy2.0 project, a high-temperature electrolyser (HTE) with a nominal output of 720 kWel and a throughput of 200 m³ of hydrogen per hour is being built. By the end of 2022, the electrolyser is expected to run for at least 13,000 hours and produce a total of about 100 tonnes of hydrogen. The plant also uses already available industrial waste heat from Salzgitter AG.
The green hydrogen produced is to be used in direct reduction on the one hand and also for the annealing processes, for which grey hydrogen is currently still used. The three interlocking sub-projects of Salzgitter AG are called SALCOS, WindH2 and GrInHy2.0.
