Milestone for Green Hydrogen: SOEC Pilot Plant Opens in Arnstadt

On May 27, 2025, Fraunhofer IKTS and thyssenkrupp nucera inaugurated Germany’s first pilot production facility for SOEC (Solid Oxide Electrolysis Cell) stacks in Arnstadt. This high-temperature electrolysis technology enables highly efficient green hydrogen production—crucial for decarbonizing energy-intensive industries. With an annual capacity of 8 MW, the plant marks a key step from research to industrial-scale application. The opening ceremony welcomed prominent figures from politics, science, and industry, including Thuringia’s Minister-President Mario Voigt. This strategic partnership strengthens Germany’s hydrogen technology ecosystem and highlights Thuringia’s role as a hub for future-oriented innovation.

The pilot plant for the high-temperature electrolysis stack technology (SOEC) developed by Fraunhofer IKTS was opened at the “Erfurter Kreuz” in Arnstadt.
