One solution is liquid hydrogen storage systems, where hydrogen is stored at cryogenic temperatures in liquid form. However, despite extensive research, an analytical framework for assessment of liquid storage systems in UAVs is still lacking. They considered a standard liquid hydrogen storage tank, consisting of inner and outer vessels, pipes, and supporters, made using SUS316L steel. "Our findings establish new standards for comprehensive safety assessment of liquid hydrogen storage tanks in UAV applications," notes Mr. Heo.
