The present invention provides a liquefied hydrogen storage container and a marine transportation means including the same. The liquefied hydrogen storage container comprises: a primary barrier which performs primary airtightness while directly contacting liquefied hydrogen stored therein; an insulating space which is formed of at least one layer on the outside of the primary barrier and filled with an insulating material therein; 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; and a final insulation layer which is formed on the outside of the cryogenic heat-blocking layer. The level of the heat-blocking liquefied gas is maintained to be higher than the uppermost layer of a structure dividing the insulating space. According to the present invention, the evaporation rate of liquefied hydrogen is significantly reduced, thereby minimizing energy loss during maritime transportation of hydrogen.
본 발명은 내부에 저장되는 액화수소와 직접 접하면서 1차적인 기밀을 수행하는 1차 방벽; 1차 방벽의 외측에 적어도 1개 이상의 층으로 형성되며 내부에 단열재가 채워지는 단열공간; 단열공간의 외측에 형성되며 내부 공간에 열차단용 액화가스로서 액화질소 또는 LNG가 수용되는 극저온열차단층; 및 극저온열차단층의 외측에 형성되는 최종단열층을 포함하고, 상기 열차단용 액화가스는 단열공간을 구획하는 구조물의 최상부층보다 수위가 높게 유지되는 것을 특징으로 하는 액화수소 저장용기 및 이를 포함하는 해상 운송 수단을 제공한다. 본 발명에 의하면, 액화수소의 증발률이 현저하게 저감되어 수소의 해상 운송시 에너지 손실을 최소화할 수 있다는 효과가 있다.
