HyPSTER goes into work-over

A decisive stage for the first hydrogen storage demonstrator

The implementation of HyPSTER, the first green hydrogen storage demonstrator in a salt cavern located in Etrez, near Lyon (France), is progressing.

Since 4 March 2023 and until mid-April, site operator Storengy has been carrying out work-over operations aimed at changing the equipment in the salt cavern for equipment compatible with hydrogen.

HyPSTER is the first salt cavern hydrogen storage demonstrator supported by the Clean Hydrogen Partnership and is currently being developed in Etrez. With a total budget of €13 million, it aims to better identify the position of storage in the hydrogen value chain to support the development of the hydrogen sector in Europe.

The implementation of this project, launched in January 2021, is progressing with the well work-over. This operation aims to replace the production elements installed in the well with equipment compatible with hydrogen. This operation is at the heart of the HyPSTER project, as the new equipment will enable tests to be completed to confirm the salt cavern’s ability to store hydrogen produced by intermittent renewable energy sources.

As an operator of industrial sites, Storengy designs solutions for the storage of natural gas and hydrogen and the production of renewable gases, but also ensures their implementation in the field. This new key step is being carried out in collaboration with various trades, such as Arverne - the drilling contractor, Schlumberger - the completion supplier, Vallourec - the pipe supplier and Technip FMC - the wellhead supplier.       

Zoom on the HyPSTER project, an essential link in the development of the renewable hydrogen sector:

This demonstrator studying the underground storage of renewable hydrogen sets the stage for the creation of an industrial-scale hydrogen sector and its technical and commercial reproducibility at other sites in Europe. It is a further step towards flexible and large-scale supply of renewable, low-carbon energy.

About the project:

This project benefits from financing through the Fuel Cells and Hydrogen 2 Joint Undertaking (now Clean Hydrogen Partnership) under the grant agreement no. 101006751. This public-private partnership has received the support of the Horizon 2020 research and innovation programme by the European Union, Hydrogen Europe and Hydrogen Europe Research.
