A gas treatment system for a ship is disclosed. A gas treatment system for a ship according to an embodiment comprises: a storage tank for accommodating natural gas including liquefied natural gas and natural boil-off gas generated therefrom; a hydrogen production unit which receives the natural gas of the storage tank and reforms the supplied natural gas into synthesis gas containing hydrogen; a re-liquefaction unit for receiving waste gas excluding hydrogen among the synthesis gas produced by the hydrogen production unit and re-liquefying carbon dioxide in the waste gas; a gas supply line for supplying the natural gas of the storage tank to the hydrogen production unit; a first waste gas line for supplying waste gas excluding hydrogen from the synthesis gas produced in the hydrogen production unit to the re-liquefaction unit; and a recovery line for recovering the carbon dioxide reliquefied in the re-liquefaction unit to the storage tank. Therefore, the present invention can re-liquefy the carbon dioxide in the waste gas generated in the process of producing the hydrogen and simultaneously produce the hydrogen in one vessel.
