GTT’s liquid hydrogen containment and handling systems get CLassNK nod

French containment system builder GTT has received approval from Japanese classification society ClassNK for its membrane type containment and cargo handling systems for liquefied hydrogen (LH2) carriers.

The containment system is scalable and can be adapted “to any size of LH2 carrier without major design modifications,” GTT claims.

Hydrogen has a low volumetric energy density. It needs to be stored either in a compressed form at high pressure (350-700 bar) or in a cryogenic form at very low temperatures (−252.8°C) to ensure it does not escape into the atmosphere during transport.

GTT believes that “the ability to transport hydrogen in liquefied form at -253°C is one of the technological challenges,” which need to be overcome “to build a reliable, efficient and competitive hydrogen supply chain.”

“We are convinced that the development of containment systems for the transport of liquid hydrogen is a key element in accelerating the energy transition,” GTT chief executive Philippe Berterottière says.
