On 20 March 2024, the European consortium met for the official launch of the FrHyGe* project, supported and funded by the European Union through the Clean Hydrogen Partnership. This 43 M€ project aims to validate the underground storage of hydrogen in salt caverns on an industrial scale. The project will allow the deployment of an industrial demonstrator in Manosque, France, as well as the replication study on the Harsefeld site in Germany and more widely at a European scale.
