H₂ is emerging as a major solution for decarbonizing a number of industrial processes and transport. However, its accessibility at an affordable cost remains a crucial challenge. But the unique physical properties of this gas make the task a complex one. To meet some of these challenges, Vallourec has developed a unique H₂ storage solution, presented this at its Aulnoye-Aymeries plant in northern France, in the form of a vertical compressed H₂ gas storage demonstrator.

This modular system, with its small footprint, makes it easy to integrate into demanding industrial environments, and offers a secure solution for large-scale H₂ storage.

“We are here to create the conditions for the success of the H₂ sector. The emerging H₂ market offers excellent growth prospects. It demonstrates the value of our technologies to the new energy sectors and confirms the Group's ambition to be a key player in the energy transition and low-carbon economy within the 2050 timeframe,” said Philippe Guillemot, Vallourec Group Chairman and CEO.

The installation – the first of its kind in the world—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 H₂ value chain and is an enabler for global decarbonization.

“Our vertical H₂ storage solution marks an important milestone for Vallourec. This project offers, reliable, modular and competitive large scale storage capacity. Vallourec offers a unique value proposition for the development of the H₂ economy,” said Ulrika Wising, SVP Energy Transition and member of Vallourec's Executive Committee.

Our solution is an underground system, capable of storing up to 100 tons of H₂ gas under maximum safety conditions. The system is suitable for green H₂ producers, users for industrial applications and heavy mobility.

“Our vertical storage system is made up of steel tubes connected to each other, considerably reducing the footprint. Our solution, underground and vertical, minimizes risks, guaranteeing optimal safety performance, perfectly meeting the constraints of customers with limited space,” said Vincent Designolle, H₂ Director, Vallourec.
