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.

    본 발명의 일 실시예에 의해 액화수소 운반선이 제공된다. 본 발명의 일 실시예에 따른 액화수소 운반선은, 선체와, 선체에 설치되며 액화천연가스를 저장하는 연료탱크와, 선체에 설치되며 액화수소를 저장하는 적어도 하나의 화물탱크와, 연료탱크로부터 공급되는 액화천연가스를 연소하여 동력을 생성하는 연소기관과, 연소기관에서 배출되는 배기가스에 이산화탄소를 흡수하는 흡수제를 분사하여 이산화탄소를 제거하는 흡수탑과, 흡수탑으로부터 이산화탄소가 흡수된 흡수제를 공급받아 흡수제로부터 이산화탄소를 분리하는 재생탑을 포함하는 이산화탄소포집장치, 및 연료탱크에 저장된 액화천연가스와 화물탱크에 저장된 액화수소 중 적어도 하나가 자연 증발하여 생성된 증발가스를 공급받아 스팀을 생성하는 보일러를 포함하되, 재생탑은 보일러에서 생성된 스팀을 이용하여 흡수제로부터 이산화탄소를 분리할 수 있다.
