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 workover operations aimed at changing the equipment in the salt cavern for equipment that is 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 workover. This operation aims to replace the production elements installed in the well with equipment that is 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.
