The present invention provides a marine transportation means, which comprises: a liquefied gas storage container including a primary barrier inside which liquefied hydrogen is stored, an insulating space which surrounds the primary barrier and is filled with insulating materials, and a cryogenic heat-blocking layer which is formed on the outside of the insulating space and contains liquefied nitrogen or LNG as a liquefied gas for heat-blocking in an inner space; a fuel cell which produces electricity using liquefied hydrogen boil-off gas generated from liquefied hydrogen stored inside the primary barrier as fuel; and an energy storage system which stores the electricity generated in the fuel cell. According to the present invention, the evaporation rate of liquefied hydrogen stored inside the liquefied hydrogen storage container is significantly reduced, and the boil-off gas generated inside the liquefied hydrogen storage container can be converted into a separate energy source and stored, such that energy loss can be minimized and energy can be efficiently used.
본 발명은 내측에 액화수소가 저장되는 1차 방벽과, 1차 방벽을 둘러싸며 내부에 단열재가 채워지는 단열공간, 그리고 단열공간의 외측에 형성되며 내부 공간에 열차단용 액화가스로서 액화질소 또는 LNG가 수용되는 극저온열차단층을 포함하는 액화가스 저장용기; 1차 방벽 내부에 저장되는 액화수소로부터 발생하는 액화수소 증발가스를 연료로 사용하여 전기를 생산하는 연료전지; 및 연료전지에서 생산된 전기를 저장하는 에너지저장시스템을 포함하는 해상 운송 수단을 제공한다. 본 발명에 의하면, 액화수소 저장용기 내부에 저장되는 액화수소의 증발률이 현저하게 저감되고, 액화수소 저장용기 내부에서 발생하는 증발가스를 별도의 에너지원으로 변환하여 저장하는 것이 가능하므로, 에너지 손실을 최소화하고 효율적으로 이용할 수 있다는 효과가 있다.
