Nucera Acquires Danish High-Pressure Electrolysis Assets

Thyssenkrupp Nucera strengthens its hydrogen market position by acquiring strategic technology assets from Green Hydrogen Systems. The Dortmund-based company takes over patents and a fully equipped test center in Denmark. The deal closes in late summer 2025.

Dortmund-based technology company Thyssenkrupp Nucera is expanding strategically in the hydrogen market: On June 20, the group announced the acquisition of core technology assets from insolvent Danish specialist Green Hydrogen Systems (GHS). The acquisition package includes valuable intellectual property and a fully operational test center at the Danish Skive site, complete with prototype.

"This acquisition underscores our clear commitment to the green energy transition and consolidates our technology leadership in hydrogen," emphasizes Nucera CEO Dr. Werner Ponikwar. Financing comes entirely from cash reserves, with the purchase price remaining confidential.

High-Pressure Technology as Competitive Edge

Central to the takeover is GHS' innovative high-pressure electrolysis technology, operating at pressures up to 35 bar. "This approach offers significant advantages for industrial customers who typically require pressurized hydrogen," explains CEO Ponikwar. The technology reduces or eliminates the need for downstream compression of produced hydrogen.

The acquired test center in Skive serves as a springboard for accelerated development cycles. Nucera plans to integrate the gained insights directly into the next generation of alkaline water electrolyzers.

"The transaction fits seamlessly into our long-term technology roadmap and rests on solid financial foundations," adds CFO Dr. Stefan Hahn.

SOEC Series Production Already Launched

Parallel to alkaline electrolysis (AWE), Nucera is pushing the commercialization of high-temperature electrolysis. In late May, together with Fraunhofer IKTS, it launched pilot production for SOEC stacks (Solid Oxide Electrolysis Cell) in Arnstadt. The facility targets 8 megawatts annual capacity and gathers experience for large-scale industrial expansion.

SOEC systems operate at high temperatures and reduce energy consumption by 20 to 30 percent compared to conventional processes. Nucera is systematically expanding its portfolio of AEL electrolyzers, which will benefit from GHS know-how in the future. The company references over 600 completed electrolysis projects with more than 10 GW total capacity.
