fuelcellsworks, Industry Highlight: “HyPSTER”, the First Green H2 Storage Demonstrator
  • Large-scale green H2 storage demonstrator supported by the European Union

HyPSTER is the first underground green hydrogen storage project in a salt cavity supported by the European Union. The demonstrator will be set up in France (in Ain). The project with a total budget of 13 million euros has just obtained a subsidy from the Fuel Cells and Hydrogen Joint Undertaking (FCH 2 JU) of 5 million euros.

At the start of 2021, the project is starting with a basement and surface engineering study which precedes an experimentation phase in real conditions. This project will make it possible to better identify the place of storage in the hydrogen value chain. Ultimately, this demonstrator aims to support the development of the hydrogen economy in Europe.

HyPSTER stands for Hydrogen Pilot STorage for large Ecosystem Replication

Storage, a strategic link in the green hydrogen sector

An essential link in the development of underground green hydrogen storage in Europe , this demonstrator is fully in line with the economic decarbonisation trajectory and the European recovery plan, by integrating one of the links in the value chain of hydrogen still untested: storage. Its objective: to test the production and storage of green hydrogen in a salt cavity on an industrial scale and the techno-economic replicability of this process on other sites in Europe.

HyPSTER marks a new step towards an exit from fossil fuels in favor of carbon-free renewable energies.

For the production of green hydrogen, the Etrez site will rely on local renewable energies (photovoltaic, hydraulic) and a 1 MW electrolyser . Ultimately, the installation will allow the production of 400 kg of hydrogen per day (the equivalent of the consumption of 16 hydrogen buses *).

This production will make it possible to test the storage of green hydrogen at a level of 2 to 3 tonnes initially until the total capacity of the identified salt cavity is used, i.e. 44 tonnes (the equivalent of the daily consumption of 1,760 hydrogen buses *).

Be, a site ideally located at the crossroads of production, storage and uses

The Etrez storage site, located north-west of Bourg-en-Bresse (01) on the European North-South corridor, is the leading French site for the storage of natural gas in salt caverns in terms of capacity.

The area where the site is located is particularly dynamic for the development of the uses of green hydrogen thanks to large-scale projects such as the Zero Emission Valley (ZEV Project) in the Auvergne-Rhône-Alpes region, the construction of hydrogen production units and distribution stations in the Burgundy Franche Comté region or the chemical valley with the presence of many manufacturers.

Focus on hydrogen:

Hydrogen from a renewable production chain has a key place in the energy transition.

It can serve different uses:

– in industry (chemicals, electronics, glass, metallurgy, etc.), this hydrogen can be used to produce different materials, but also for energy uses (steam for example), and thus decarbonize the production chain  ;

– for transport and mobility, it replaces traditional fuels while having the advantage of generating no emissions, of having a long range and a very short refueling time.

Thanks to green hydrogen, renewable energy sources can now benefit sectors that are difficult to decarbonise.
