ITM Power and RWE expand collaboration through new 150 MW electrolyzer deal

September 22, 2025, by Aida Čučuk

UK’s electrolyzer manufacturer ITM Power has entered into a capacity reservation agreement with German energy company RWE for 150 MW of NEPTUNE V units.

The reservation, equivalent to 30 units, reportedly foresees call-offs by 2027. It follows RWE’s operation of ITM’s 4 MW pilot plant and the ongoing delivery of 200 MW of electrolyzers for RWE’s GetH2 Nukleus project in Lingen, Germany.

NEPTUNE V is ITM’s latest generation containerized, green hydrogen plant solution. As disclosed, each unit integrates the balance of plant within a compact containerized design, supporting “rapid deployment, simplified installation, and reliable operation.” According to ITM, NEPTUNE V can be interconnected to form bigger container-based plants.

Dennis Schulz, CEO of ITM Power, said: “We are proud to expand our collaboration with RWE. Building on our strong relationship developed through the joint execution of the GetH2 Nukleus project, this additional 150MW capacity reservation underlines RWE’s confidence in our technology and delivery capability. Repeat business with a global leader in energy is the strongest validation of our strategy, our products, and our people.”
