The TKK Report 2026 reiterated the demonstration-stage plan toward 2027 for a large liquefied hydrogen tank, including a test tank approximately one-tenth the size of the actual tank. - FY2026AdvancedAnnual report
「The Company plans to construct a bench-scale test tank in fiscal 2026 and complete demonstration testing in fiscal 2027.」
Development of the large liquefied hydrogen tank has advanced to a plan to construct a bench-scale test tank approximately one-tenth the size of the full-scale unit in fiscal 2026 and complete demonstration testing in fiscal 2027. - FY2026-H1AdvancedAnnual report
「This responds to the organizational change effective 1 April 2025, under which the Next-Generation Energy Development Business will be dissolved as part of a reorganization and transferred to the Next-Generation Energy Development Center, an organization directly under the Representative Director and President, to accelerate research and development of large liquefied hydrogen tanks in anticipation of a future hydrogen society. This will create an environment for faster development-related decision-making and enable the Company to establish manufacturing technologies for large liquefied hydrogen tanks.」
To accelerate research and development of large liquefied hydrogen tanks, the organization has advanced to the stage of transferring to the Next-Generation Energy Development Center, with the aim of enabling faster decision-making and establishing manufacturing technologies. - FY2023AdvancedAnnual report
「This fiscal year is the final year of the NEDO Hydrogen Society Construction Technology Development Project, in which the Company has participated since fiscal 2019. The Company achieved the three stated objectives: (1) establishing a vacuum evacuation system, (2) establishing a method for calculating heat input to the bottom of the inner tank, and (3) establishing a welding procedure using SUS316L welding materials. This establishes the basic elemental technologies for large liquefied hydrogen tanks.」
In the final year of the NEDO project, the Company achieved the three objectives of vacuum evacuation, heat-input calculation and SUS316L welding procedures, establishing the basic elemental technologies for large liquefied hydrogen tanks. - FY2021AdvancedAnnual report
「In the NEDO Hydrogen Society Construction Technology Development Project, in which the Company has participated since fiscal 2019, research and development is under way to establish (1) a vacuum evacuation system, (2) a method for calculating heat input to the bottom of the inner tank, and (3) a welding procedure using SUS316L welding materials. Favorable results have been obtained to date.」
Development of the large liquid hydrogen tank has progressed toward establishing specific technologies for vacuum evacuation, heat-input calculation and SUS316L welding procedures, with favorable results obtained. - FY2018AdvancedAnnual report
「Strength verification and thermal insulation performance tests are currently being conducted on the proposed insulation structures for the main sections, including the sides, bottom, roof and anchor straps. The results have been generally favorable, and preliminary design is under way. The Company plans to make an industry presentation next fiscal year.」
Development of the liquid hydrogen tank has produced generally favorable results in tests of the main sections and has advanced to the preliminary design stage, with an industry presentation planned for the following fiscal year. - FY2017AdvancedAnnual report
「The materials and structure for the main insulation sections, a key development item, have now been selected and determined, and strength verification and thermal insulation performance tests are under way. The Company plans to complete the various tests and conduct preliminary design by the next fiscal year.」
Development of the 10,000-cubic-meter-class liquid hydrogen tank has advanced to the specific stages of determining the main materials and structure, conducting tests, completing the tests and carrying out preliminary design by the following fiscal year. - FY2016First statedAnnual report
「The Company began joint development with Tokyo Institute of Technology (Tokodai) aimed at constructing the world’s largest liquid hydrogen tank. The objective over the next 3 years is to enable construction of a tank in the 10,000-cubic-meter class, far exceeding the world’s current largest capacity. The Company is developing a large, flat-bottomed, cylindrical, vertical liquid hydrogen tank of the same type as LNG tanks, for which it has extensive experience, with the aim of constructing a full-scale unit.」
The Company has provided specific details of the joint development with Tokodai, including a 3-year period, a tank in the 10,000-cubic-meter class, and the application of LNG tank technology.
