Design and analysis of liquid hydrogen fuel tank for heavy duty truck

This research analyses the codes and standards related to the design of liquid hydrogen fuel tanks for heavy-duty trucks, thereby proposing design principles and procedures. Guidelines for design are given in ISO 13985, and several related standards and codes are analyzed. The procedure consists of three parts: material selection used in the design part based on the initially given requirements, structural analysis of the design load to see structural stability, and thermal analysis to judge the thermal performance of the fuel tank. Because structural analysis and thermal analysis affect each other, iterative analysis is required to satisfy the acceptance criteria. A liquid hydrogen fuel tank for 540 HP grade heavy duty truck was designed following the proposed design and procedure. Structural analysis under eight load combinations ensured that the designed liquid hydrogen fuel tank met the permissible limits of the codes and standards, while thermal analysis estimated the thermal performance.
