The Ministry of Industry in South Korea, driven by the goal of enhancing transport efficiency, has initiated the development of liquefied hydrogen carriers. These carriers, by liquefying gaseous hydrogen to -253°C, reduce its volume significantly, offering a promising solution for future transportation needs. The government aims to commercialize these carriers and has formed a promotion team to advance this innovative technology. Japan, with the world's first liquefied hydrogen carrier Suiso Frontier, has already made strides in this sector. The strategic approach involves securing core technologies, demonstration projects, and fostering a strong public-private cooperation system. The Ministry plans to invest a substantial amount to build the world's largest demonstration ship by 2027. Through collaboration with shipbuilding companies, universities, and researchers, South Korea is forging ahead in the development of liquefied hydrogen carriers. With 43 R&D projects involving 101 organizations in progress, the focus is on creating a cooperative ecosystem to drive advancements in this technology. The government's proactive involvement and support aim to establish these innovations as global standards and ensure South Korea's leadership in this high-tech and high-risk sector of large-scale liquefied hydrogen carriers.
