HD KSOE’s liquefied hydrogen system gets DNV nod

The concept design of the liquified hydrogen system "comprises propulsion system, tank & insulation system and cargo handling system”, a DNV spokesperson told ENGINE.

Classification society DNV has approved in principle a hydrogen system developed by South Korea’s HD Korea Shipbuilding & Offshore Engineering (HD KSOE) and its subsidiaries HD Hyundai Heavy Industry (HD HHI) and Hyundai Mipo Dockyard (HMD).

The new system is a key component of HD KSOE’s liquefied hydrogen carrier prototype.

“One of the core technologies HD KSOE is focusing on is a large containment system that includes the hydrogen DF (dual-fuel) engine and a new insulation system that enables scale-up of containment system,” the DNV spokesperson added.

The hydrogen system has been conceptualised to use boil-off gas from hydrogen stored onboard the vessel to power hydrogen dual-fuel engines and fuel cells, DNV said in a statement. It will be installed on HD KSOE's proposed liquefied hydrogen carrier to enable large-scale hydrogen storage and transportation. 

The new system is a step towards resolving challenges related to efficient transportation of hydrogen by ships, DNV said.

HD KSOE and its subsidiaries have partnered with Australian oil and gas firm Woodside Energy, industrial cryogenic specialist Cryostar and gas infrastructure developer Linde Engineering to commercialise the liquefied hydrogen carrier by 2030.
