South Korea's top shipbuilders and steelmakers, in collaboration with the Korean Register, have formed a strategic R&D alliance to secure leadership in the emerging market for liquefied hydrogen (LH2) carriers. The memorandum of understanding (MOU) signed by HD Korea Shipbuilding & Offshore Engineering, Samsung Heavy Industries, Hanwha Ocean, POSCO, Hyundai Steel, and the Korean Register focuses on standardizing material testing for liquefied hydrogen ships. The primary goal of the alliance is to tackle the technical hurdles of transporting hydrogen, which requires extreme cooling and compression. Core technologies such as 'liquefied hydrogen cargo holds' are crucial for safely storing hydrogen at ultra-low temperatures. By researching material properties for external impacts and promoting international standardization, the alliance aims to advance South Korea's competitiveness in liquefied hydrogen carriers. This initiative follows challenges faced by the Korean shipbuilding industry, emphasizing the need to overcome design flaws and achieve technological independence. By partnering with the steel industry, the alliance aims to enhance South Korea's technological edge in LH2 carriers. The collaboration highlights the importance of research and verification at ultra-low temperatures to ensure material toughness. The stakeholders stress the objective of securing leadership in hydrogen carriers using domestic technology, aiming to set new standards in the global market. By developing liquefied hydrogen cargo holds independently, South Korea plans to dominate the next-generation hydrogen carrier market and play a key role in the sustainable energy transition. The alliance's current focus includes sharing experimental results, enhancing technological competitiveness, and ensuring safety for LH2 carriers. South Korea's proactive stance in cleaner energy solutions could have far-reaching environmental and economic benefits, potentially fostering innovation and job creation in the industry.
