“Green hydrogen is produced from stochastic renewable energy sources, meaning when the wind is blowing or when the sun is shining. For hydrogen to be able to play its role in the greening of industry, a steady feed of hydrogen can only be ensured if hydrogen can be stored in large quantities.  The underground storage of hydrogen in natural cavities or in man-made salt caverns could provide such a large-scale buffer. The Fuel Cells and Hydrogen Joint Undertaking, as per the priorities set by the European Commission and European Industry and Researchers, has published a topic on the “Cyclic testing of renewable hydrogen storage in a small salt cavern”. The successful HYPSTER project will thus be implementing green H2 production at industrial scale and storage facility in France in order to assess its technical and economic viability.”





No, HyPSTER is not a new fashion trend. It stands for Hydrogen Pilot STorage for large Ecosystem Replication.

HyPSTER is the first EU supported project for large scale green hydrogen underground storage in salt caverns. The demonstration facility will be located in Etrez, France.

Officially launched in January 2021, the project aims to use salt cavern storage to connect hydrogen projection by electrolysis to industrial and mobility uses. It will also test the technical and economic reproducibility of the process to other sites throughout Europe.

To learn more about HyPSTER, visit the dedicated website.





Is Hypster a project that can be replicated in Europe, or even in the world?

HyPSTER project will pave the way to the green hydrogen storage. The demonstration thru an industrial-scale operation of cyclic H2 storage in salt caverns will support the emergence of the hydrogen energy economy in Europe in line with overall Hydrogen Europe road-mapping.

ESK is located in Germany, do you have remarked differences between the German and French Hydrogen Startegy?

On the first view, both strategies look very similar. Both mention targets of 5 – 6.5 GW electrolyzer capacity until 2030 and a budget of 7 bn Euro. However, the French strategy clearly allocates to which sectors the hydrogen should go, instead, the German strategy is more specific on the source of the required electricity. But the most important fact is, that both countries as well as several other European neighbors now actually have a hydrogen strategy and, that all are committed to boost the hydrogen economy and build a common infrastructure.

Do you have already work on European Projects involving hydrogen?

Yes, we have already worked on :

  •          PRETZEL: Novel modular stack design for high pressure PEM water electrolyzer technology with wide operation range and reduced cost
  •          PEGASUS: PEMFC based on platinum Group metAl free StrUctured cathodeS 

In the next newsletter, you will discover Element Energy, Ineris, Inovyn & Axelera.





In this section, you will find market information (legal framework, EU H2 Strategy…).

  • HYDROGEN ACT : This report has been published in April 2021 by Hydrogen Europe and draw the first legal framework but intend to focus on infrastructure and market aspects. Learn more here.
  • First Edition: European Observatory for Renewable and Low Carbon Hydrogen. You can download the study completed by SIA Partners. This Observatory analysed 12 European countries, focusing 8 different topics, surrounding renewable and low carbon hydrogen, from the upstream to the downstream. Learn more here.

















This section will be to share the different press articles about the project.
