Elogen announces that it has been selected by Storengy as part of the HyPSTER[1] project for the supply of a PEM electrolyser with a power of 1 MW for the Etrez site (Ain – France).

Elogen, a GTT group company, announces that its unique membrane electrolyser technology has been selected by Storengy, as part of the HyPSTER project, to store green hydrogen produced from renewable energies. Elogen will design and produce the 1MW PEM (Proton Exchange Membrane) electrolyser and will install its technology in 2022 at the Etrez site.

HyPSTER is a large-scale green hydrogen storage demonstrator, coordinated by Storengy, the European leader in natural gas storage. The company is surrounded by six other partners with complementary expertise: INERIS, Armines / Polytechnique, INOVYN, ESK, Element Energy, AXELERA.

HyPSTER is the first underground green hydrogen storage project in a saline cavity to be supported by the European Union. It will allow a better assessment of the place of storage in the hydrogen value chain.

The Etrez site, France’s leading natural gas storage site in salt caverns in terms of capacity, will rely on local renewable energies (photovoltaic, hydraulic) to produce green hydrogen. The facility will allow the production of 400 kg of green hydrogen per day. This production will test the storage of green hydrogen at a level of 2 to 3 tonnes initially until the full capacity of the identified salt cavity is used, i.e. 44 tonnes. Experimentation with the storage of hydrogen in a saline cavity and the production of green hydrogen will start in 2023.

Jean-Baptiste Choimet, CEO of Elogen, comments: “TThis 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 player in natural gas storage in Europe[2]. 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.”
