Hypster - First renewable hydrogen storage demonstrator entered in operational phase
Products


Information
HyPSTER aims to test and validate the role of hydrogen storage in the hydrogen value chain, in order to replicate it on a large scale and support the deployment of the hydrogen industry in Europe.
The project includes a hydrogen storage demonstrator and a renewable hydrogen production components.
2024: several injections of green hydrogen were carried out in a salt cavern at Storengy's Etrez-Bresse Vallons site, confirming the hydrogen-tightness of the well and cavern in successive stages.
2025: for around 3 months, a hundred simulations of hydrogen injection and withdrawal cycles will be carried out using brine injection and withdrawal, to assess the impact of these cycles on the stability of the salt cavern.
These tests are crucial to confirm the feasibility of large-scale hydrogen storage in a salt cavern.
At the same time, the hydrogen production platform will be commissioned.
The renewable hydrogen will be produced from renewable electricity using a 1 MW electrolyser based on PEM technology.
