Analysis of carbon neutral pathway and carbon price of container ships based on marginal abatement cost
In order to study the carbon neutral path of a container single ship,as well as to analyze the influence of carbon price on the carbon neutral path,this paper takes a proposed 12 000 TEU container ship as the research object,adopts the theoretical assessment method of marginal abatement cost,and carries out the research on the carbon neutral path of a single ship with a combination of technological measures,operational measures and alternative fuels based on a three-type scheme,and analyzes the relationship between marginal abatement cost and carbon price.The results show that:the combination of technical measures and operational measures can achieve about 28.62％emission reduction;most technical and operational measures are cost-effective;with the carbon price increasing to a given value,the later additional costs of methanol and ammonia dual fueled ships is gradually becoming economical;carbon taxes alone cannot achieve carbon neutrality by 2050;ammonia dual fueled ships have the potential to compete commercially with methanol dual fueled ships.
