In a significant step towards decarbonising the maritime industry , Lloyd’s Register (LR) has granted Approval in Principle (AiP) to the large-scale vacuum-insulated liquid hydrogen (LH₂) tank system developed by HD Korea Shipbuilding & Offshore Engineering Co., Ltd. (HD KSOE).
The challenge of liquid hydrogen in the maritime industry
Liquid hydrogen , which is stored at extremely low temperatures (-253°C), presents complex technological challenges, especially in its large-scale transportation. HD KSOE’s innovative design has managed to overcome one of the main barriers: vacuum insulation in large-scale tanks.
This system improves the scale of storage and significantly reduces the time required to reach vacuum in large tanks, optimizing the manufacturing process in shipyards.
Technological advances and international collaboration
The development of this system has been made possible thanks to the collaboration between several leading companies in the energy and maritime industry. Companies such as Woodside Energy , Mitsui OSK Lines (MOL) and Hyundai Glovis actively participated in the validation of the design.
Through rigorous design evaluations and performance testing, the companies have confirmed the effectiveness of the vacuum system developed by HD KSOE , positioning this advancement as a benchmark for future applications in the hydrogen industry.
Implications for the energy transition
This achievement represents an important step towards the commercialisation of liquid hydrogen and a crucial breakthrough for large-scale hydrogen transport , one of the biggest challenges facing the maritime industry on its path to decarbonisation. New technological solutions contribute significantly to global net-zero emissions goals, boosting the development of hydrogen projects in the energy sector.
Sung-Gu Park, President of LR North East Asia, highlighted that this AiP, in addition to reinforcing LR’s commitment to maritime innovation, also sets a new benchmark in the hydrogen industry.
