DNV has awarded Approval in Principle (AiP) to Hyundai Heavy Industries' (HHI) unit, KSOE, for their innovative vacuum-insulated large-scale liquefied hydrogen tank technology. This recognition highlights the importance of developing cost-effective and safe large-scale liquid hydrogen storage to fulfill the potential of hydrogen in decarbonizing industries like transportation, shipping, and power generation. By significantly reducing the time required for vacuum insulation in large tanks, HD KSOE has made substantial progress in making liquid hydrogen ships a reality. Industry leaders have praised this achievement, acknowledging the significance of large-scale hydrogen storage in accelerating the adoption of hydrogen as a key component of the energy transition. The verification test conducted by HD KSOE, with the participation of Woodside Energy, MOL, Hyundai Glovis, and DNV representatives, marks a crucial milestone in the study of transporting liquefied hydrogen. The successful demonstration of tank scale-up signifies a major step towards commercialization and showcases the dedication and innovation of HD KSOE in the field. Vidar Dolonen, DNV Regional Manager for Korea and Japan, emphasized that the award of AiP represents a significant advancement in the journey towards a global hydrogen economy. The collaboration between HD KSOE and Woodside Energy aims to develop 80,000-cubic-meter liquefied hydrogen carriers with large hydrogen tanks, contributing to the establishment of an integrated maritime transportation value chain for large-scale liquid hydrogen. Driven by the goal of achieving net-zero emissions, the focus on technological solutions for energy shipping, including hydrogen, reflects a collective effort to drive the energy transition and meet sustainability targets. This collaborative approach between industry leaders underscores the commitment to a cleaner energy future and paves the way for safer and more efficient hydrogen transport methods.
