... ABSTRACT The required thickness of a large aboveground liquefied hydrogen tank was estimated for SUS304L and high-Ni steel. For a 230,000 m 3 tank with atmospheric insulation and 0.2 MPa internal hydrogen gas pressure, the required plate thickness was 47 mm for SUS304L and 28 mm for high-Ni...

.... These approaches, while informative, often result in designs that are suboptimal in terms of material usage. A recurring observation is the excessive use of structural steel compared to estimates derived from reference models. This discrepancy not only indicates potential inefficiencies but also underscores a gap...
