Revolutionizing the Maritime Hydrogen Landscape
Lloyd’s Register (LR) has granted an Approval in Principle (AiP) to HD Korea Shipbuilding & Offshore Engineering Co., Ltd. (HD KSOE) for an innovative vacuum-insulated liquid hydrogen (LH2) tank system. This recognition comes after successful testing of a large-scale vacuum chamber, marking a significant milestone in maritime hydrogen technology.
The newly developed vacuum insulation system is tailored to address critical challenges in the hydrogen industry, particularly focusing on the effective storage and transportation of liquefied hydrogen at a chilling temperature of -253°C. With this advanced technology, the large tanks resemble that of thermos flasks, an achievable feat previously untested on such a large scale in maritime applications.
Notably, while NASA’s largest LH2 tank has a capacity of 5,000 m³, maritime applications require tanks that can hold over four times that volume. HD KSOE’s revolutionary design offers an efficient solution by significantly reducing the time taken to achieve vacuum conditions in larger tanks.
Industry collaborations with prominent entities like Woodside Energy and Mitsui OSK Lines aided in the design and validation process. The collective efforts have led to groundbreaking results, garnering support from international classification societies. This innovative development is seen as a significant leap towards achieving sustainable solutions and decarbonization in the maritime sector.
