Abstract
A liquefied hydrogen storage tank is provided in a storage facility storing a large amount of hydrogen in a liquefied state or a vehicle transporting liquefied hydrogen and a liquefied hydrogen storage tank. The liquefied hydrogen storage tank is a storage container storing liquefied hydrogen. The liquefied hydrogen storage tank includes an inner space including a lower space in which liquefied hydrogen is stored and an upper space in which a gas is stored and further includes a heat inflow prevention unit disposed in the upper space or at an interface between the upper space and the lower space and preventing inflow of thermal energy into the lower space through the upper space. The temperature of the liquefied hydrogen storage tank is controlled, the generation rate of boil-off gas from liquefied hydrogen is controlled, and the liquefied hydrogen storage tank is maintained at a low pressure.
