摘　　要：先进压缩空气储能系统是一种具有广泛应用前景的储能技术,对其展开全生命周期能耗及二氧化碳排放研究,对促进储能技术发展和政策制定有指导意义。本工作以10 MW先进压缩空气储能系统为研究对象,建立了压缩空气储能系统的全生命周期模型,基于实际机组、国家标准及相关文献等对生命周期各阶段进行清单分析,获得了压缩空气储能系统的全生命周期能耗、能效及二氧化碳排放,并进行了敏感性分析。研究结果表明,系统全生命周期度电能耗和度电二氧化碳排放量分别为5.653 MJ和36.73 g,净能量效率为63.68%;运行阶段的能耗和二氧化碳排放占比最大,分别为99.16%和90.49%;系统运行效率、系统寿命及发电时间都是全生命周期二氧化碳排放的重要影响因素,而全生命周期能耗对系统运行效率的敏感性较大。Advanced adiabatic compressed air energy storage technology has broad application prospects,as its life-cycle energy consumption and carbon dioxide emission research are of guiding significance for promoting energy storage technology development and policy formulation.A 10-MW advanced adiabatic compressed air energy storage system was the research object;a life cycle assessment model of the compressed air energy storage system was established;a life cycle inventory of each stage was conducted based on the actual unit,national standards,and reference literature;and the life-cycle energy consumption and carbon emissions of the system were analyzed.The research results showed that the life-cycle energy consumption and the life-cycle carbon emissions per kilowatt-hour of electricity generation were 5.65 MJ and 36.73 g,and the life-cycle net energy efficiency was 63.7%,from which energy consumption and carbon emissions accounted for the largest proportions in the operation phase,99.2%and 90.5%,respectively;the heat storage,compression,and expansion systems accounted for a significantly high proportion of carbon emissions.Sensitivity analysis showed that system operating efficiency,system life,and gas storage time are important factors affecting life-cycle carbon emissions and that life-cycle energy consumption is more sensitive to system operation efficiency.
