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.
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.
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.
Philippe Guillemot, Chairman of the Board of Directors and CEO of Vallourec, commented: “We are delighted to expand our collaboration with H2V in the high-growth field of green hydrogen. This memorandum of understanding demonstrates Vallourec’s determination to use its expertise to help build a cutting-edge hydrogen industry. It confirms the Group’s ambition to become a key player in the transition to a low-carbon economy.”
“The pooling of our expertise is an excellent signal for carbon reduction in the Marseille Fos industrial port basin,” said Alexis Martinez, Managing Director of H2V. “I am delighted with the future potential of this agreement, which is designed to address electricity supply constraints. Being able to stockpile hydrogen with Delphy will enable us to implement a more flexible supply system.”
