The World Energy Network research program of the Japanese New Sunshine Project was divided into 3 phases[1] during the period 1993 to 2002, its goal was to study the distribution of liquid hydrogen with hydrogen tankers[2] based on the LNG carrier technology of self-supporting tank designs such as the prismatic and spherical tank.
[4] The "Suiso Frontier" collected a cargo of liquid hydrogen from the port of Hastings in Victoria, Australia on 28 January 2022 and arrived back in Kobe, Japan at the end of February, 2022 with the cargo.
[6] In November 2022, Approval in Principle (AiP) was granted by Nippon Kaiji Kyokai (ClassNK) for Kawasaki Heavy Industries's dual fuel generator engine using hydrogen gas as fuel, which will be installed on a 160,000 m3 liquefied hydrogen carrier developed by Kawasaki.
Kawasaki intends to conduct a demonstration test of this engine after installing it on a large-scale liquefied hydrogen carrier which is planned to be commercialized in the mid-2020s.
[4][7] In June 2023, Kawasaki Heavy Industries announced its completion of technological development for a cargo containment system (CCS) to be used in large liquefied hydrogen carriers.
