摘要
碳足迹是量化碳排放的重要工具,能够为燃煤发电碳减排提供数据支撑.为研究燃煤机组的电力碳足迹及影响因素,基于生命周期法进行了实际案例计算及敏感性分析.碳足迹计算结果显示,300 MW燃煤发电机组的单位上网电量碳足迹为 0.932 kgCO2e/(kW·h),主要排放源为煤炭燃烧,占比约为 79%,其次是煤炭的上游生产和加工,占比约为 20%.碳足迹和碳核查的对比分析结论表明,减碳不仅应从燃煤电厂的常规减碳方式入手,降低上游的煤炭供给阶段排放仍是一种有效方案.
Abstract
Carbon footprint,as an essential tool for quantifying carbon emissions,provides data support for carbon emission reduction in coal-fired power generation.To investigate the electricity carbon footprint of coal-fired units and its influencing factors,actual case calculations and sensitivity analysis were conducted based on the life cycle method.The carbon footprint calculation results indicate that the carbon footprint per unit of grid-connected electricity for a 300 MW coal-fired power generation unit is 0.932 kgCO2e/kW·h.The primary emission source is coal combustion,accounting for approximately 79%,followed by upstream coal production and processing,accounting for approximately 20%.The comparative analysis of carbon footprint and carbon verification concludes that reducing carbon emissions should not only focus on conventional methods in coal-fired power plants,but also consider reducing emissions in the upstream coal supply stage as an effective solution.
