基于生命周期法的煤电碳足迹评估
Life-Cycle Carbon Footprint Assessment of Coal-fired Power Generation
摘要
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.关键词
