The researches on ship-based carbon capture,utilization,and sequestration(CCUS)technology conducted in both China and abroad were tracked,and key contents and main research results were sorted out.Based on the advantages and disadvantages of different CCUS technology paths,the application feasibility of current CCUS technology on ships was analyzed.The technical route to carry out CCUS was proposed for the rapidly developing liquefied natural gas ships.The problems existing in current ship-based CCUS technology were summarized,targeted recommendations were put forward,and development direction of key ship-based CCUS technology was discussed.Research results show that the ship-based CCUS technology can significantly reduce emissions in short term and is applicable to the vast majority of carbon-fueled ships,including those in operation and the newly constructed.Foreign countries are actively deploying the ship-based CCUS technology real-ship verification research,but the research in China is mostly at the stage of conceptual design and simulation research.Due to the simple transformation,high technology maturity,and low cost,the chemical absorption method in the post-combustion capture methods is most suitable for the ship-based carbon capture at present.But to solve the problems of high energy consumption and large system sizes,it is necessary to accelerate the exploration of advanced chemical solvents with better performance and more revolutionary capture methods.Liquid storage is currently the most mature storage method,but its safety and economy need improvement.There is an urgent need to accelerate the construction of storage and transportation methods dominated by large CO2 carriers and to promote the construction of CO2 transfer and reception infrastructure at ports and marine platforms.CO2 has great development prospect in oil displacement and gas-freeing in offshore oil-gas fields,seawater desalination,and energy catalytic reforming,but CO2 utilization technology for ships needs to be scaled up and industrialized and requires synergistic development of related industrial technologies.Marine sequestration of liquid CO2 or dry ice is the future development trend,but there is an urgent need to improve relevant standards,laws,and regulations to promote the development of sequestration equipment and technology.It is necessary to explore a set of standardized and systematic carbon emission management modes to promote the mutual matching and promotion of CCUS technology and establish a complete,green,economical,and efficient ship-based CCUS industry chain.4 tabs,11 figs,95 refs.
