Abstract

To meet the International Maritime Organization (IMO) target of 20% reduction of CO2 emissions from marine activities by 2020, application of Carbon Capture and Storage (CCS) on ships is considered as an effective way to mitigate CO2 emissions while other low carbon shipping technologies are being developed. Literature reviews on CCS methods for onshore applications indicate that the current CCS technologies could not be implemented on boards directly due to various limitations on ships. A novel chemical CO2 absorption and solidification method for CO2 storage on-board is proposed, presented and analyzed. Technical feasibility with explanation of principles and cost assessment are carried out for a case ship with a comparison to a conventional CCS method. The paper also presents results obtained from laboratory experiment including factors that affect the absorption. Theoretical study and laboratory experiment illustrate the proposed CO2 solidification method is a promising, cost effective and feasible method for CO2 emissions reduction on ships.
