The Korean Register (KR) has recently published a guide focusing on the thermal properties of cryogenic insulation materials for the safe storage of cryogenic fuels, including LNG and liquid hydrogen. This release comes in response to the 2023 International Maritime Organization (IMO) Strategy, which targets significant reductions in greenhouse gas (GHG) emissions from ships. The strategy sets ambitious goals of reducing emissions by 20% in 2030, 70% in 2040, and achieving net-zero emissions by around 2050. To meet these targets, the maritime sector is shifting towards not only using LNG but also exploring long-term alternatives like hydrogen and ammonia. KR, in collaboration with various research institutions in South Korea, has been working on developing insulation system technology crucial for utilizing cryogenic low- and zero-carbon fuels. The report elaborates on the insulation systems for liquid hydrogen at extremely low temperatures, emphasizing the importance of environmental considerations in the design process. The aim is to establish stable storage technology for hydrogen on ships, enabling its efficient import and utilization through marine transport. Additionally, this advancement aligns with the Republic of Korea's Hydrogen Economy Roadmap. The collaboration between KR and organizations like the Korea Institute of Machinery & Materials, Pusan National University, and Seoul National University of Science and Technology highlights the collective efforts towards enhancing insulation systems in cryogenic environments. KR's Executive Vice President mentioned that the guide is poised to become a standard for material selection and the development of innovative insulation systems. Furthermore, KR's recent Approval in Principle for an Onboard CO2 Capture System developed by Hanwha Ocean demonstrates a continued commitment to environmentally friendly solutions in the maritime industry.
