Abstract: The shipping industry, as a major emitter of greenhouse gases, has increasingly highlighted the urgency of carbon reduction. A series of mandatory policies and regulations on carbon emissions in the international shipping industry have gradually entered into the mandatory implementation stage in order to reduce carbon emissions in the shipping industry. The shipping industry is therefore facing enormous pressure on carbon reduction. The current study reviews and summarizes the shipping carbon emission policies and regulations issued by the International Maritime Organization (IMO), and compares the feasibility and applicability of various carbon reduction technologies in the shipping industry from both policy and technical aspects. The carbon capture technology is a direct and effective technology for the current shipping industry to address the carbon emission regulations. Based on the state-of-art of the carbon capture technology for ship exhaust gas, the challenges faced by the ocean-going ships in using carbon capture technology are analyzed from the technical requirements, operating costs and energy consumption, combined with the operation characteristics and exhaust emission characteristics of the ocean-going ships. The suggestions and measures are provided for appropriate marine carbon capture technology. The development direction of the carbon capture technology for the exhaust emissions of the ocean-going vessels is prospected based on the historical data. This study can provide references for the formulation of the carbon emission policies for China's shipping industry and the development and application of the ship carbon reduction technologies.

Key words: shipping industry, international maritime organization (IMO), carbon emission policies, ocean-going vessels, carbon capture

摘要: 航运业作为温室气体排放的主要来源之一,碳减排的迫切性日益凸显。为降低碳排放,一系列国际航运业碳排放的政策法规已逐步进入到强制执行阶段,航运业面临着巨大的压力。文章通过对国际海事组织颁布的航运碳排放政策法规体系进行梳理与总结,从政策层面和技术层面对比研究各种碳减排技术在船舶领域中的可行性与适用性。碳捕集技术是当前航运业应对碳排放法规的1种直接有效的技术,文中基于船舶尾气碳捕集技术发展现状,结合远洋船舶运行特点和尾气排放特性,从技术要求、运行成本、能源消耗等方面分析远洋船舶使用碳捕集技术所面临的挑战,提出船用碳捕集适用技术的建议及措施,并结合历史数据,对远洋船舶尾气碳捕集技术的发展方向进行展望,为我国航运碳排放政策制定及船舶碳减排技术的发展和应用提供参考。
