Vallourec, Baker Hughes team up in green hydrogen

Vallourec has signed an MoU with Baker Hughes focused on advancing hydrogen storage solutions for the green hydrogen market, including green ammonia, sustainable fuels, and green steel manufacturing. It includes the future integration of Vallourec’s Delphy hydrogen storage solution with Baker Hughes compression.

Collaboration will focus on optimizing compression–storage configurations and determining the most efficient operating pressures for each application.

Delphy is capable of storing up to 100 tons of green hydrogen gas vertically, providing a minimal surface footprint. It has been certified by Bureau Veritas and DNV.

Ecopetrol is advancing a green hydrogen plant at its Cartagena refinery, targeting a first-half 2026 in-service date.
