Vallourec Achieves Milestone in Hydrogen Storage with Delphy Qualification

Vallourec, a leader in premium seamless tubular solutions, has secured qualification for its hydrogen storage solution, Delphy, from DNV. Delphy is the world's first vertical gaseous hydrogen storage solution, capable of storing between 1 to 100 tons. Its design, extending up to 100 meters underground, is tailored for challenging industrial environments.

The project, launched in 2022, involved a team of approximately thirty experts. Vallourec's rigorous development, testing, and validation processes have culminated in this validation, ensuring safety and reliability. Vallourec has already engaged in collaborations with H2V and NextChem Tech, with around 50 projects being explored in France and internationally.

The increasing demand for storage solutions, driven by regulatory requirements and the flexible nature of green hydrogen production, is expected to benefit from Delphy's capabilities. Vallourec's achievement positions it strongly in the hydrogen market and supports global decarbonization efforts.
