HD KSOE has received the world's first Approval in Principle from KR for its innovative vacuum-insulated large-scale liquid hydrogen tank system. This advancement in clean energy transportation technology comes after successful validation tests, showcasing the system's feasibility and cutting-edge design. The extreme cryogenic conditions required for storing liquid hydrogen at -253°C have long posed challenges, but HD KSOE's solution aims to revolutionize this aspect. By dramatically reducing the time needed to create a vacuum in large tanks, the process has been shortened from several months to just a few days. Collaboration with global hydrogen industry leaders like Woodside Energy, MOL, and Hyundai Glovis further validated the system's effectiveness and stability. KR's evaluation confirmed compliance with standards, highlighting the potential of the hydrogen industry. The industry experts' remarks emphasize the significance of this achievement in enabling efficient design and construction of liquid hydrogen ships while paving the way for commercialization. This milestone sets a strong foundation for future advancements in the field, driving the energy transition and supporting net-zero goals.
