[0002] Ships are generally large in size and require large power plants to drive them. Therefore, the power plants consume more fuel, which produces more carbon dioxide after burning. Excessive carbon dioxide will lead to the greenhouse effect. Therefore, in order to reduce carbon dioxide emissions, existing large ships are generally equipped with carbon capture systems, which store the captured carbon dioxide in storage tanks, and then process the stored carbon dioxide uniformly after the ship goes ashore.
