Under a new memorandum of understanding, the companies will look to combine Vallourec’s Delphy hydrogen storage solution with Baker Hughes’ compression systems.

The partnership will focus on optimising compression-storage configurations, while establishing the most efficient operating pressures for each hydrogen application.

They say a potential combined solution could help reduce the total cost of ownership of clean hydrogen solutions.

The Delphy system stores gaseous hydrogen in pipe assemblies under the surface at depths of up to 100 metres. Vallourec says the solution can store up to 100 tonnes of hydrogen gas and has been certified by Bureau Veritas and DNV.

The company said the system could help overcome space constraints in industrial sites.

Vallourec is already operating a demonstrator of the technology in northern France.

Baker Hughes manufactures hydrogen compression systems for small-scale uses like refuelling stations, up to large petrochemical installations.

Vallourec CEO, Philippe Guillemot, said the firm’s capabilities were “highly complementary” to Baker Hughes’ compression technologies.

Baker Hughes has been increasing its activity in hydrogen technologies. In the past couple of years, the firm has announced plans to acquire cryogenics specialist Chart Industries, work with Australian high-pressure storage firm Provaris, and more various others.

The company already has technology in its arsenal related to green, blue and turquoise hydrogen production, liquefaction, compression, refuelling, and ammonia production – as well as upstream processes like power generation and water desalination.
