Japanese companies Kawasaki Heavy Industries, Imabari Shipbuilding, and Japan Marine United Corporation are set to collaborate on a joint study to design and construct liquefied hydrogen carriers. The study will focus on establishing a construction scheme that optimizes the companies' resources for this purpose. Liquefied hydrogen carriers are seen as crucial for enabling the transportation of large volumes of hydrogen, thus supporting the development of a hydrogen supply chain. The partners aim to strengthen their cooperative relationship through this study, with the ultimate goal of commercializing a liquefied hydrogen supply chain to contribute to the realization of a carbon-neutral society. Kawasaki Heavy Industries has been actively engaged in various partnerships related to liquefied hydrogen, including agreements with CB&I, INPEX Corporation, Iwatani Corporation, Toyo Engineering Corporation, JGC Corporation, and Chiyoda Corporation. These collaborations focus on promoting commercial-use liquefied hydrogen supply chains, developing supply chains for hydrogen transport from Australia to Japan, and enhancing front-end engineering design for a liquefied hydrogen supply chain. Overall, the efforts of these Japanese companies highlight a positive sentiment towards hydrogen as they work towards sustainable solutions and the commercialization of hydrogen supply chains.
