Provided in an embodiment of the present invention is a liquefied hydrogen carrier. The liquefied hydrogen carrier according to an embodiment of the present invention can comprise: a hull; a fuel tank which is installed in the hull to store liquefied natural gas; a combustion engine which generates power by combusting the liquefied natural gas supplied from the fuel tank or evaporated gas produced when the liquefied natural gas is vaporized; a first fuel supply pipe which connects the fuel tank and the combustion engine; at least one cargo tank which is installed in the hull to store liquefied hydrogen; a fuel cell which generates electricity by receiving hydrogen gas produced when the liquefied hydrogen from the cargo tank is vaporized; a second fuel supply pipe which connects the cargo tank and the fuel cell; a plurality of cofferdams which are formed to be spaced between the fuel tank and the cargo tank, and between the cargo tanks; a heat exchange line which forms a closed-loop independent cycle such that a heat medium circulates within and which passes through each of the plurality of cofferdams; and a heating unit which is installed on the heat exchange line and heats the heat medium passing through the cofferdam. Therefore, the liquefied hydrogen carrier can save energy consumed in heating the heat medium.
