It’s been a great topic of discussion at ENGIE since 2021, and now it’s here! HyPSTER, the first renewable hydrogen storage demonstrator in a salt cavern, was officially inaugurated on September 15th. This highly anticipated project, supported by the European Union and the Clean Hydrogen Partnership, paves the way for the creation of an industrial sector for renewable hydrogen storage.

The HyPSTER demonstrator was officially inaugurated on September 15th in Etrez, near Bourg-en-Bresse. The ceremony was attended by Catherine MacGregor, CEO of ENGIE, Charlotte Roule, CEO of Storengy, Mirela Altanasiu, Interim Executive Director of the Clean Hydrogen Partnership, Virginie Grinola-Bernard, Mayor of Bresse-Vallons, and numerous elected officials and business leaders.

Located at the Storengy storage site in Etrez, near Bourg-en-Bresse, France, the demonstrator was developed by a consortium of nine European companies and coordinated by Storengy, a subsidiary of ENGIE. It stems from a Research & Development project that confirmed the potential of the salt cavern known as “EZ 53” for hydrogen storage.

HyPSTER, aligning with the pioneering spirit of the flagship project in the Auvergne-Rhône-Alpes region, known as the “Zero Emission Valley” (the largest renewable hydrogen mobility project in France), adds an essential piece to the puzzle: storage.
