DNV Awards Approval in Principle to KSOE for Innovative Hydrogen Tank Technology

Ulsan, 20th Jan. 2025: DNV has granted an Approval in Principle (AiP) to HD Korea Shipbuilding & Offshore Engineering (HD KSOE) for their groundbreaking vacuum-insulated large-scale liquefied hydrogen tank technology. This advancement is a significant step towards practical storage solutions for liquefied hydrogen (LH2), essential for decarbonizing industries such as transportation, shipping, and power generation.

HD KSOE’s innovative method significantly reduces the time needed to create a vacuum, making larger tanks viable. This solution was successfully tested using a large chamber, marking HD KSOE as the first shipbuilder to demonstrate this approach’s viability.

Representatives from Woodside Energy, Mitsui O.S.K. Lines (MOL), Hyundai Glovis, and DNV observed the testing. Jason Crusan, VP Energy Solutions at Woodside Energy, highlighted the achievement’s importance in designing and constructing liquid hydrogen ships efficiently. Jotaro Tamura, Senior Management Executive Officer at MOL, and Chi O, Kwon, Vice President of Hyundai Glovis, emphasized the milestone’s significance in the commercialization of liquefied hydrogen transport.

Dr. Byeongyong Yoo, Vice President at HD KSOE, expressed the company’s dedication to providing technological solutions for large-scale energy shipping, including LNG, LPG, Ammonia, CO2, and now hydrogen. Vidar Dolonen, DNV Regional Manager for Korea and Japan, praised the collaboration with HD KSOE as a crucial step towards realizing a global hydrogen economy.

HD KSOE is also collaborating with Woodside Energy to develop 80,000-cubic-meter liquefied hydrogen carriers equipped with these large hydrogen tanks, aiming to create an integrated maritime transportation value chain for large-scale liquid hydrogen
