- Abstract
In order to store hydrogen in a liquid state at −253 °C, a double-structured tank trailer with inner and outer vessels is essential for maintaining insulation through a vacuum. While the smaller support of the inner vessel reduces heat loss, it raises concerns regarding its susceptibility to external factors like driving conditions. This study focuses on ensuring the safety of the tank trailer through design and analysis. Inner vessel thickness was determined using the membrane stress theory, verified per KGS guidelines. Structural safety of the 2.5-ton trailer was assessed following ASME Sec. VIII Div. 2 guidelines, simulating full hydrogen charge and adhering to CGA-H3. ASME BPVC XII specifications were applied, and a redesign mitigated stress concentration issues considering driving conditions. Following these steps, successful design and safety verification of the 2.5-ton trailer were achieved.
