HD Korea Shipbuilding & Offshore Engineering (HD KSOE) has achieved ABS approval in principle (AIP) for a tank design that revolutionizes large-scale hydrogen transport and storage. The newly developed vacuum insulation system by HD KSOE significantly reduces the time required to establish a vacuum in extensive tanks, a crucial factor for safe transportation. This technology allows for the preservation of a vacuum state at -253℃, ensuring secure and loss-free conveyance of substantial liquid hydrogen volumes. ABS conducted comprehensive design reviews that comply with class and statutory regulations. The Senior Vice President and Chief Technology Officer of ABS, Patrick Ryan, highlighted the pivotal role of hydrogen in decarbonization and the necessity for advanced systems to support extensive liquid hydrogen storage and shipping. Dr. Byeongyong Yoo, Vice President of HD KSOE, emphasized the company's commitment to developing technological solutions for large-scale energy transportation, including LNG, LPG, and now hydrogen. Global energy and shipping giants like Woodside Energy, Mitsui O.S.K. Lines (MOL), and Hyundai Glovis participated in the validation test and are actively engaged in the collaborative creation of an 80,000 cbm liquid hydrogen carrier. Industry leaders from these companies lauded the milestone achievement, expressing confidence in the efficient design and construction of liquid hydrogen vessels. This technological advancement signifies a significant step forward in the energy transition and decarbonization efforts, showcasing dedication to innovation and collaboration for a sustainable future.
