聚焦于电动与混合动力船舶的温室气体减排量核算方法及其节能减排的潜力,通过构建核算方法模型,明确定义基准线情景和项目情景,对各年度的基准线排放量、项目排放量、泄漏排放量和项目减排量进行详细计算,深入分析了项目的减排效果、可持续性和环境贡献.结果表明:①减排效果显著,计入期内的合计减排量达到14 781.09 t,平均年减排量达到1 478.11 t;②可持续性较高,项目排放量和项目减排量呈现逐年递减的趋势,同时仍保持在相对较高水平;③环境贡献显著,项目的减排量占基准线排放量的比例每年都在50％以上,最高达到80％以上.研究成果可为温室气体减排量核算提供参考,有助于推动营运船舶领域的绿色低碳发展.
Emission Reduction Calculation Method for Electric and Hybrid Propulsion Vessels:Analysis and Application Scenarios
This study focuses on the method for calculating greenhouse gas emission reductions in electric and hybrid propulsion vessels,as well as the potential and challenges of energy-saving emission reductions.By constructing a calculation model and defining baseline and project scenarios,we performed detailed calculations on annual baseline emissions,project emissions,leakage emissions,and project emission reductions.Additionally,we undertook an in-depth analysis of the emission reduction effect,sustainability,and environmental contribution of the project.The findings of this study indicates:① Substantial emission reduction effect,with a cumulative reduction of 14,781.09 tons during the accounting period and an average annual reduction of 1,478.11 tons.② High level of sustainability.The project emissions and emission reductions follow a decreasing trend while maintaining at relatively high levels.③Notable environmental contributions.The proportion of emission reductions from the project to baseline emissions has been above 50 percent each year,peaking at over 80 percent.The conclusions of this paper offer a practical and viable method for greenhouse gas emission calculations and provide reliable references for promoting the green and low-carbon development in operational vessels.
