基于IMO温室气体减排的某船队减碳路线

Research on Fleet Carbon Reduction Route Based on IMO GHG Reduction Strategy

为应对温室气体变化,国际海事组织(IMO)提出2030年较2008年碳强度降低40%,2050年实现国际航运温室气体净零排放的减排战略,国际航行船舶需采取适当措施满足IMO减碳要求;同时中国提出“3060双碳目标”,2030年前CO_(2)排放达到峰值,2060年前实现碳中和。利用某船队减碳分析模型,以某航运公司船队为研究对象,分析不同燃料路径。评估结果表明,以绿氨和绿甲醇为主要燃料的路径,同时考虑碳捕捉,可实现碳中和。研究提出了适用于目标船队的减碳路线,对国内船队碳减排具有实际指导意义。

To address the challenges posed by GHG,IMO proposed a carbon reduction strategy of reducing carbon intensity by 40%in 2030 compared with 2008,reducing carbon intensity by 70%in 2050 compared with 2008,and reducing greenhouse gases by 50%.International navigation ships need to take appropriate measures to meet the IMO's carbon reduction requirements.At same time,China proposed that carbon dioxide emissions should reach the peak by 2030 and achieve the“2060 double carbon target”of carbon neutrality by 2060.In this paper,using the fleet carbon reduction analysis model,taking the fleet of a shipping company as the research object,the different fuel routes were analyzed.The evaluation results showed that carbon neutrality can be achieved by using green ammonia and green methanol as the main fuels while considering carbon capture.The study put forward the carbon reduction route suitable for the target fleet,which has practical guiding significance for the carbon reduction of domestic fleet.
