In accordance with one embodiment of the present invention, provided is a liquefied hydrogen carrier. In accordance with one embodiment of the present invention, the liquefied hydrogen carrier includes: a hull; a fuel tank installed on the hull and storing liquefied natural gas; at least one cargo tank installed on the hull and storing liquefied hydrogen; a combustion engine generating power by combusting the liquefied natural gas supplied from the fuel tank and intake air cooled by an air cooler; a boiler generating steam by receiving at least one of first boil-off gas generated by the spontaneous vaporization of the liquefied natural gas in the fuel tank and second boil-off gas generated by the spontaneous vaporization of the liquefied hydrogen in the cargo tank; and an absorptive cooler cooling a working fluid circulating through the air cooler by using steam as a heat source. Therefore, the present invention is capable of lowering a fuel consumption rate through an improvement in combustion efficiency.
