Vallourec unveils hydrogen storage solution: “Delphy”

Vallourec inaugurates its vertical compressed gas hydrogen storage demonstrator in Aulnoye-Aymeries, northern France. The compact footprint of this modular system makes it easy to integrate into demanding industrial environments and delivers a secure large-scale hydrogen storage solution. 

The installation is based on tubes and connections with extensively-proven sealing technology and corrosion resistance. It demonstrates the validity of Vallourec’s innovative concept, establishes Vallourec as a key player in the hydrogen value chain and is an enabler for global decarbonisation. The solution is an underground system, capable of storing up to 100 tonnes of hydrogen gas under maximum safety conditions. The system is suitable for green hydrogen producers, users for industrial applications and heavy mobility. 

To support the commercial development of this storage solution, Vallourec is launching it under a new brand name “Delphy”. 

This hydrogen storage technology is part of the wider Vallourec® New Energies offering, designed to support the energy transition, including geothermal, carbon sequestration, solar and biomass segments. New Energies’ offerings could contribute between 10% and 15% of Vallourec’s EBITDA by 2030.
