HD Korea Shipbuilding & Offshore Engineering (HD KSOE) has achieved ABS approval in principle (AIP) for a tank design facilitating large-scale hydrogen transport and storage. The vacuum insulation system developed by HD KSOE streamlines the process of creating a vacuum in large tanks, crucial for efficient transportation. This technology allows for the maintenance of a vacuum state at -253℃, ensuring the secure and loss-free transport of significant quantities of liquid hydrogen. ABS conducted design reviews according to class and statutory requirements, underscoring the importance of safety protocols. The ABS Senior Vice President highlighted hydrogen's pivotal role in decarbonization, emphasizing its versatility as fuel, feedstock, and energy storage. Key industry players such as Woodside Energy, MOL, and Hyundai Glovis are actively engaged in joint development efforts with HD KSOE for an 80,000 cbm liquid hydrogen carrier, showcasing industry collaboration towards sustainable energy solutions. The global validation test represents a significant step towards commercializing the transportation of liquefied hydrogen, with stakeholders stressing the importance of scaling up tank size to advance the technology. ABS, renowned for its expertise in gas carriers classification, is at the forefront of advocating for comprehensive decarbonization and sustainability solutions in the maritime sector, further promoting the utilization of hydrogen for a greener future.
