Hydrogen storage: H2V and Vallourec sign partnership agreement

Vallourec, a world leader in premium tubular solutions, and H2V, a subsidiary of the SAMFI-Invest group, have signed a partnership agreement at the Hyvolution trade show.

This partnership targets closer co-operation between the two players, with a view to drawing on each other’s technical skills, market knowledge and development capabilities in future projects. This includes investigating the potential integration of the Delphy storage solution, developed by Vallourec, with the green hydrogen production and use projects developed by H2V in Marseille Fos. H2V has been a French pioneer in the mass production of green hydrogen since 2016.

This agreement follows Vallourec’s entry into the hydrogen storage market with the launch of Delphy, its first large-scale vertical solution. Delphy consists of an underground system capable of storing up to 100 tonnes of gaseous hydrogen under maximum safety conditions. The system is designed for green hydrogen producers and users for industrial applications and heavy mobility. Delphy enables users to streamline their costs and offer high supply safety levels. This solution establishes Vallourec as a key player in the hydrogen value chain andrepresents a driving force for carbon reduction worldwide.

Over the past two years, Vallourec has been developing Vallourec^® New Energies, its portfolio of solutions designed to support energy transition, including geothermal, hydrogen storage, carbon sequestration, solar and biomass markets.

With an estimated workforce of over 50 in 2026, H2V has a commercial portfolio of projects which will scale up to 1.8 GW of capacity in 2030 and more than 3 GW in 2040, based mainly in France, Belgium, and the United Kingdom.
