According to one embodiment of the present invention, a liquefied hydrogen carrier is provided. The liquefied hydrogen carrier, according to one embodiment of the present invention, comprises: a hull; a fuel tank installed in the hull and storing liquefied natural gas; at least one cargo tank installed in the hull and storing liquefied hydrogen; a combustion engine for generating power by burning the liquefied natural gas supplied from the fuel tank; a carbon dioxide capture device including an absorption tower which removes carbon dioxide by injecting an absorbent for absorbing carbon dioxide into exhaust gas discharged from the combustion engine, and a regeneration tower which receives, from the absorption tower, the absorbent in which carbon dioxide has been absorbed and separating the carbon dioxide from the absorbent; and a boiler for generating steam by receiving boil-off gas generated by spontaneous evaporation of at least one of the liquefied natural gas stored in the fuel tank and the liquefied hydrogen stored in the cargo tank. The regeneration tower may separate the carbon dioxide from the absorbent by using the steam generated by the boiler. Therefore, boil-off gas can be efficiently treated.
