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 in an inner space; and an ammonia synthesis facility which produces ammonia by reacting liquefied hydrogen evaporation gas generated from liquefied hydrogen stored inside the primary barrier with liquefied nitrogen boil-off gas generated from the liquefied nitrogen stored inside the cryogenic heat-blocking layer. 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 액화질소가 수용되는 극저온열차단층을 포함하는 액화가스 저장용기; 및 1차 방벽 내부에 저장되는 액화수소로부터 발생하는 액화수소 증발가스와 극저온열차단층 내부에 수용되는 액화질소로부터 발생하는 액화질소 증발가스를 반응시켜 암모니아를 생성하는 암모니아 합성설비를 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.
