Liquid hydrogen will be widely used in the future. In recent years, billions of dollars have been invested in liquid hydrogen storage and transportation technology in the automotive industry worldwide. However, the use of liquid hydrogen for passenger cars, city buses and trucks requires the design of on-board liquid hydrogen storage tanks with better safety performance, particularly in the event of collisions or more severe conditions that may be encountered during the driving of the vehicle, which can lead to the on-board liquid hydrogen storage tanks being subjected to great impact, which places extremely high demands on the design of the safety systems of the storage tanks.
The potential safety hazard of the liquid hydrogen storage tank mainly lies in that liquid hydrogen in the storage tank is gasified into gaseous hydrogen, so that the pressure in the tank is increased to generate deformation and even explosion, and the like.
