ENERTRAG has signed a contract with Elogen, a GTT Group company, for the development and production of a 10 MW PEM (Proton Exchange Membrane) electrolyser in December 2022. Elogen will install its technology near Magdeburg (Germany) in 2024. The project is one of many green hydrogen projects currently being developed by ENERTRAG in North and Middle Germany.

The Elogen electrolyser will produce up to four tonnes of green hydrogen per day, the electrical energy needed for electrolysis coming exclusively from renewable sources.

The electrolyser will enable the power system to compensate for wind and solar fluctuations. The green hydrogen produced will contribute to decarbonising heavy industry and long-distance trucking, to producing electricity in the event of “dark-doldrums” and, in the medium term, to supplying the 100% hydrogen pipelines of the gas transmission system operator ONTRAS.[1]

Jean-Baptiste Choimet, Managing Director of Elogen, declares: " We are particularly proud that the Elogen membrane electrolysis technology has been chosen for its performance by ENERTRAG, a leading European player in innovative renewable energy solutions. This is also an important step for Elogen since this contract concerns an electrolyser with a capacity of 10 MW, confirming the scaling-up of our technology for larger projects.”

Manuela Blaicher, Head of PtX Project Development at ENERTRAG SE, states: “ENERTRAG is very proud to announce this step towards a 10 MW electrolysis capacity in Germany with many possibilities of deployment, both in industry and in the mobility sector. With this reference plant, we will produce hydrogen from renewable energies on an industrial scale.” 

 “Dark doldrums” (from the German “Dunkelflaute”) is a period during which there is neither wind nor sun, making it impossible or very limited the production of solar or wind energy.[1]
