Hydrogen Explosion
BLEVE of hydrogen storage tank could occur when a liquid hydrogen container collides, or hydrogen overflows into the vacuum layer when the internal wall of a storage tank fails under fatigue. Because of the damage to the insulation layer, the temperature in the tank rises suddenly and the liquid hydrogen in the container will be overheated.
