Vallourec has signed a memorandum of understanding (MOU) with Baker Hughes to collaborate on the development of hydrogen storage solutions for the green hydrogen market.
The agreement aims to establish long-term cooperation across the industrial green hydrogen value chain, including green ammonia, sustainable fuels and green steel production, as well as applications in the clean power sector such as data centres. As part of the MOU, Vallourec’s Delphy underground hydrogen storage solution is expected to be integrated with Baker Hughes’ compression technologies.
The collaboration will focus on optimizing compression-storage configurations, defining efficient operating pressures for different applications, and helping customers reduce total cost of ownership while improving competitiveness.
Delphy is Vallourec’s market-ready underground hydrogen storage system, capable of storing up to 100 tons of green hydrogen in a vertical configuration. The solution is designed for high-pressure operation with a limited surface footprint and has been certified by Bureau Veritas and DNV. Vallourec said the partnership with Baker Hughes strengthens its position in the emerging green hydrogen value chain.
Headquartered in Meudon, France, Vallourec operates in more than 20 countries, with key production hubs in the US and Brazil. The company is a global leader in premium seamless tubular solutions for the oil and gas industry, with an annual production capacity of 2.1 mln tons.
