This tank is to be installed in the domestic terminal (Ohgishima, Kawasaki), which is planned to be constructed based on a Green Innovation Fund Project named “Liquefied Hydrogen Supply Chain Commercialization Demonstration Project” *1 subsidized by the New Energy and Industrial Technology Development Organization (hereinafter NEDO), designating Japan Suiso Energy, Ltd. (JSE) as a managing company.

Hydrogen is being looked at as an ultimate clean energy which emits no CO2 even when combusted; however, it poses key issues such as technological establishment and infrastructure development of storage facilities under a cryogenic environment of -253°C as well as upsizing of storage facilities intended for commercialization. Recently, by developing our unique structures and insulation system, we have started the construction work of the commercially-sized above-ground flat-bottom cylindrical liquefied hydrogen storage tank for the first time in the world. Therefore, the tank can store a greater amount of liquefied hydrogen compared with conventional above-ground spherical tanks in the vacuum heat insulation system.

Our years-long abundant know-how to manufacture flat-bottom cylindrical LNG storage tanks are incorporated into these tanks, together with our track record of manufacturing, operation and maintenance of spherical liquefied hydrogen storage tanks with a storage capacity of 540 m3 for Tanegashima Space Center, which was managed by NASDA (current JAXA)*2 in the 1980s, as well as the design and manufacturing technologies for a spherical liquefied hydrogen storage tank*3 constructed at Kobe Airport Island in 2020 with the largest storage capacity in Japan of 2,250 m3.

We will contribute to the fulfillment of carbon-neutral societies by expanding our lineup through further upsizing of liquefied hydrogen storage tank and by actively promoting the establishment of a hydrogen supply chain while solving a variety of technical issues.
