Economic Research On Clean Energy Application In Yangtze River Ships Under The ’Carbon Peak And Carbon Neutralization’ Target

The Yangtze River is known as a golden waterway with the largest freight volume in the world.The Yangtze River Economic Belt not only plays an extremely important role in Chinese regional development patterns,but also globally influential.Shipping in the Yangtze River provides strong support for the development of the Yangtze River Economic Belt,functioning as the ‘main artery’ of its economic and social development,and the ‘backbone’ of its comprehensive transportation system.Under the ‘Carbon Peak and Carbon Neutralization’ Target,the application of green technology on the ships operating in the Yangtze River should be strengthened to promote the highquality development of the Yangtze River shipping and the basin economy.Clean energy is the main measurement applied as a green technology for ships to reduce carbon emissions,and it is also the main starting point for the shipping industry to achieve the ‘Carbon Peak and Carbon Neutralization’ Target.Evaluating the economy of applying clean energy to ships in the Yangtze River is of great significance,since it is the main factor restricting the real application.Currently,China has officially launched a unified national carbon emission trading market,and this carbon trading mechanism to be fully implemented brings new opportunities and challenges to the shipping industry in the Yangtze River.Economic analysis that includes the carbon trading mechanism is more suitable for the future development of the Yangtze River shipping.The composition and quantification of the operating cost after the implementation of the carbon trading mechanism and the application of clean energy,as well as the comprehensive economic evaluation,are the key issues to be solved urgently for ships in the Yangtze River,and there are no mature results that can be cited.It is worth noting that the fuel cost of ships in the Yangtze River accounts for about 50%of operating costs,and the ship energy consumption is an important parameter that affects fuel costs and ship economy.The existing energy consumption quantification model usually uses the whole process average method,but actually,the operating condition of a ship changes rapidly for the reason that the navigation environment of the Yangtze River trunk line varies greatly in different seasons and different sections.So,the whole process average method is not suitable for ships in the Yangtze River.Aiming at the complex navigation environment of the Yangtze River,this paper introduces the carbon trading mechanism to deconstruct the operating costs of ships powered by clean energy in the Yangtze River.A quantitative model for the energy consumption of ships in the Yangtze River is built based on the key parameters of fuel cost,which accounts for a large proportion of operating costs.Finally,a comprehensive economic evaluation method for the application of clean energy for ships in the Yangtze River is proposed and examined.This study can provide support for the application of clean energy for ships in the Yangtze River,and facilitate the implementation of the‘Carbon Peak and Carbon Neutralization’ Target.This paper first expounds on the purpose and significance of this study,analyzes the research status at home and abroad,defines the main research content,and determines the research technology route.Then,this paper analyzes the application environment and restrictive factors of clean energy for ships in the Yangtze River and concludes that the economy is the main restrictive factor for the application of clean energy.Afterwards,a novel idea and method for economic analysis of clean energy applications in Yangtze River ships with the introduction of a carbon trading mechanism are proposed to adapt future development,that is deconstructing the operating costs of ships in the Yangtze River after applying clean energy through research and analysis and determine the economic comprehensive evaluation index to construct the economic comprehensive evaluation model of AHP-EWM-VIKOR.Next,according to the complex navigation environment and the constantly changing ship operating conditions of the Yangtze River,a quantitative model of ship fuel cost is constructed by theoretically analyzing ship operation strategies and actual navigation data based on the Matlab/Simulink simulation platform.The effectiveness of this model is verified.Finally,a comprehensive economic evaluation of different clean energy application solutions for the typical representative ship of the Yangtze River 7500-ton bulk carriers is committed to integrating above study.The research results can provide a reference for the application of clean energy for ships in the Yangtze River.
