Korean Register (KR) has granted the world's first Approval in Principle (AIP) to HD KSOE for its innovative vacuum-insulated system for large-scale liquid hydrogen (LH2) storage tank, marking a major milestone in clean energy transportation.

The groundbreaking system addresses a critical challenge in hydrogen storage by significantly reducing vacuum creation time in large tanks from months to days. This technological advancement is crucial for the large-scale transportation and storage of LH2, which requires extreme cryogenic conditions of -253°C.

In December, HD KSOE successfully conducted validation tests in collaboration with global industry leaders Woodside Energy, Mitsui OSK Lines (MOL), and Hyundai Glovis.  KR evaluated the system's compliance with domestic and international standards, confirming its effectiveness and stability and granting the AIP as a result.

This milestone underscores the growing feasibility of LH2 transportation and its role in the global energy transition. HD KSOE’s breakthrough will strengthen confidence in LH2 as a viable fuel, accelerating its path to commercialization and net-zero targets.

As the maritime sector evolves, KR remains committed to ensuring safety and technological progress in hydrogen shipping. By leveraging its expertise and global partnerships, KR will continue to play a key role in shaping a sustainable future.
