摘要采用生命周期评价方法,核算我国典型风力发电及储能系统碳足迹,以揭示其不同生命周期阶段的碳减排潜力.结果表明,我国风力发电及储能系统的碳足迹为8.44gCO₂/(kW·h),其中组件制造阶段的碳足迹贡献最大,为6.25gCO₂/(kW·h),占整个系统碳足迹的74.05%.而系统建设、运营维护和废弃处理处置阶段的碳足迹分别为1.04,1.91,-0.74gCO₂/(kW·h).通过系统边界调整分析,发现在原有的发电系统上增加储能系统可以降低系统的总电力碳足迹.

Abstract：Based on the methodology of life cycle assessment (LCA), the carbon footprint of the typical wind power system with generation and electricity storage (WPSGES) in China was calculated, so as to identify the reduction potential of carbon emission from life cycle stages. The results showed that the carbon footprint of WPSGES was 8.44gCO₂/(kW·h), which mainly came from the manufacturing process by 6.25gCO₂/(kW·h)(74.05%). Such processes as construction, operation, and end of life only contributed 1.04, 1.91 and -0.74gCO₂/(kW·h), respectively. It was also confirmed that expanding the system boundary, including power generation and storage, could reduce gross carbon footprint of WPSGES.
