Having been selected by Storengy for its technology, Elogen’s electrolyser will see the Etrez, France site produce 400kg of green hydrogen daily.

The production will test the storage of green hydrogen at a level of two to three tonnes initially until the full capacity of the identified salt cavity is used.

Experimentation with the storage of hydrogen in a saline cavity and the production of green hydrogen will start in 2023. Elogen will install its technology in 2022.

Jean-Baptiste Choimet, CEO of Elogen, said, “This new contract represents an important step for Elogen as it positions us in storage, which is a strategic link in the hydrogen value chain.

“Storengy’s choice of electrolysis technology developed by Elogen thus demonstrates the relevance and performance of membrane technology for producing hydrogen from renewable energies and consolidates our collaboration with this major play in natural gas storage in Europe.

“The HyPSTER demonstrator will play a key role in supporting the development of the green hydrogen economy in Europe and we are particularly proud to associate our innovative technology with this major project.”
