Japanese shipping company Mitsui O.S.K. Lines (MOL) and Kansai Electric Power Company (KEPCO) have signed a memorandum of understanding (MoU) to collaborate on the joint study of a liquefied hydrogen carrier. The study aims to determine the optimal design and operational requirements for vessels involved in transporting liquefied hydrogen, considering safety measures due to hydrogen's high volatility. Key areas of the study include technical and contractual relationships, supply chain establishment, cargo handling operations, ship/shore compatibility, classification societies, regulatory aspects, and economic analysis. This collaboration is significant as it marks the first agreement in Japan between a shipping company and a power generation company regarding marine transport of liquefied hydrogen. Both MOL and KEPCO are dedicated to exploring the specifics of marine transport of liquefied hydrogen to support the establishment of a hydrogen supply chain and achieve a zero-carbon society. Additionally, MOL previously partnered with Woodside, HD Korea Shipbuilding and Offshore Engineering (HD KSOE), and Hyundai Glovis to study bulk marine transportation of liquid hydrogen. This partnership focused on the technology, safety, construction, operation, and economics of a carrier with 80,000 cbm tank capacity, with the carrier design receiving approval in principle from classification society DNV.
