액화수소 인수기지의 국내외 안전기준 분석과 한국형 도입 방향

초록

As the global hydrogen economy accelerates to achieve carbon neutrality, the necessity for liquefied hydrogen (LH2) receiving terminals for large-scale, long-distance transport and storage is becoming increasingly prominent. LH2 offers exceptionally high storage and transport efficiency by reducing its volume to 1/800 compared to gaseous hydrogen; however, it necessitates advanced safety technologies and boil-off gas (BOG) management due to its cryogenic state (-253°C). Currently, South Korea lacks both design and operational experience regarding LH2 receiving terminals, and its safety standards remain in their infancy. This study systematically analyzed international safety standards, such as NFPA and ISO, and overseas cases, including the Hy touch Kobe terminal in Japan, to com- pare and review them against the domestic KGS Code. The results indicate that while domestic standards are more stringent than international ones in certain aspects, they lack detailed regulations for terminal-specific requirements, such as large-capacity storage tanks, ship-to-shore unloading, and the dynamic behavior of BOG. Based on these findings, this study proposes a three-stage roadmap and identifies technical and institutional tasks for the im- plementation of a Korean-style liquefied hydrogen receiving terminal.
