KR grants first AIP to HD KSOE for its pioneering vacuum-insulated liquid hydrogen tank, advancing clean energy transport technology.
Korean Register (KR) has granted the world's first Approval in Principle (AIP) to HD KSOE for its groundbreaking vacuum-insulated large-scale liquid hydrogen tank system, representing a major milestone in clean energy transportation technology. This recognition follows the successful completion of validation tests, which confirmed the system’s innovative design and feasibility.
The transition to a hydrogen-based society requires advanced technologies for the large-scale transport and storage of hydrogen. However, the extremely low temperatures needed to store liquid hydrogen at –253°C have historically posed significant challenges.
HD KSOE has independently developed a vacuum-insulated liquid hydrogen tank system that overcomes these obstacles with state-of-the-art solutions. This innovative design drastically reduces the time needed to create a vacuum in large tanks, cutting the process from several months to just a few days.
In December, HD KSOE partnered with prominent global hydrogen industry players, including Woodside Energy, Mitsui OSK Lines (MOL), and Hyundai Glovis, to conduct comprehensive validation tests. These trials marked a significant breakthrough as the first successful demonstration of scalable liquid hydrogen tanks while significantly reducing vacuum processing time.
KR thoroughly evaluated the system for compliance with both domestic and international standards, confirming its safety and reliability, and subsequently awarded the AIP.
