The present invention relates to a storage tank for a cryogenic liquid having a low boiling temperature, which increases liquid storage capacity by enhancing adiabatic efficiency and, more specifically, to a cryogenic liquid storage tank having a dual structure of an inner container (110) and an outer container (120), in which a vacuum is applied to the space between the inner and outer containers, and a heat insulating material is provided on the outer surface of the outer container (120), which makes it possible to: increase heat shield efficiency; decrease a heat insulation space to easily form heat insulation; and reduce the iron plate of the outer container (120). Accordingly, it is possible to significantly reduce the amount of a cryogenic liquid lost by means of gasification while storing or carrying the cryogenic liquid, thereby saving energy required for producing a cryogenic liquid to reduce the emission of CO2, which is a substance regulated for preventing global warming, and reducing the amount of LNG gasified according to the operation of an LNG fuel ship and providing safety. |
