Rheinmetall Advances Alkaline Electrolysis with New Electrode Technology for Green Hydrogen Production
Rheinmetall has unveiled a new electrode technology for alkaline electrolysis aimed at enhancing green hydrogen production efficiency and reducing costs. Set to begin pilot production next year, the project, part of the E2ngel consortium and backed by Germany's National Hydrogen Strategy, seeks to improve power density and efficiency using noble metal-free catalysts. Series production will take place at the St. Leon-Rot site, featuring a production line for electrodes suitable for multi-megawatt systems.

Rheinmetall has developed a new electrode technology for alkaline electrolysis, crucial for hydrogen production and the energy transition. Preparations for pilot production will commence next year. The project, led by Rheinmetall's subsidiary KS Gleitlager GmbH, was part of the E2ngel consortium, funded under Germany's National Hydrogen Strategy.
The objective is to enhance power density and efficiency using noble metal-free catalysts. The technology aims to reduce green hydrogen production costs by lowering investment and doubling power density or improving efficiency by over 10%.
The consortium includes the German Aerospace Centre (DLR) and McPhy Energy Germany, which validated the technology. Series production will begin at the St. Leon-Rot site, with a production line for electrodes up to two meters, suitable for multi-megawatt systems.
