Sheffield-based green hydrogen and energy storage firm ITM Power said it signed its first contract to sell a NEPTUNE V containerised electrolyser plant to Guttroff GmbH, a private German company that provides solutions for technical and medical gases, welding supplies, and engineering.

ITM Power designs and manufactures electrolysers based on proton exchange membrane (PEM) technology to produce green hydrogen, the only net zero energy gas, using renewable electricity and water.

“Launched in May this year and ideally suited for mid-sized projects, NEPTUNE V utilises ITM’s leading and proven TRIDENT stack technology,” said the Sheffield firm.

“NEPTUNE V is our full-scope 5MW containerised electrolyser plant. It provides reliable, flexible, and highly efficient hydrogen production capacity and the industry’s smallest footprint per MW.

“In July 2024, Guttroff received €5m of funding from Bavaria’s Ministry of Economic Affairs and Energy as part of the Bavarian electrolyser subsidy program to start the domestic production of green hydrogen in the area.

“The electrolyser will provide green hydrogen to a planned refuelling station.”

ITM Power CEO Dennis Schulz said: “We are delighted to have been chosen by Guttroff, a renowned gases company, to provide our best-in-class technology for their first green hydrogen project.

“Since its launch just a few months ago, NEPTUNE V has been very well received by customers, and we are excited about the level of interest”.
