摘要
为了探究蓄能式水电碳减排效果,以辽宁庄河抽水蓄能电站为案例,基于生命周期评价理论,采用过程分析和投入产出混合分析法,对该抽水蓄能电站全生命周期碳排放量进行了分组计算,并估算了上下水库在蓄水前后温室气体通量的差异.结果显示,该抽水蓄能电站全生命周期碳排放总量为209.4774万tCO_(2)e,其中运营阶段占59%,建设阶段占41%,碳排放因子为43.46gCO_(2)e/(kW·h),约为火电碳排放的1/33~1/25,平均每年可产生的减碳效益约0.88亿元.本文定量论证了蓄能式水电是清洁能源,大力发展抽水蓄能电站能够有效节能减排,为抽水蓄能电站低碳建设提供了数据支撑.
In order to explore the effectiveness of carbon reduction in energy storage hydropower,the Zhuanghe pumped storage power station in Liaoning Province was taken as a case study.Based on the life cycle assessment theory,process analysis and input-output mixed analysis were used to group calculate the carbon emissions throughout the entire life cycle of the pumped storage power station,and the differences in greenhouse gas fluxes between the upper and lower reservoirs before and after water storage were estimated.The results show that the total life-cycle carbon emissions of this pumped storage power plant is 2,094,774tCO_(2)e,of which the operation phase accounts for 59%and the construction phase accounts for 41%,with a carbon emissions factor of 43.46gCO_(2)e/(kW·h),which is about 1/33~1/25 of the carbon emissions of thermal power,and the average annual carbon reduction benefit can be about 88million yuan.This paper quantitatively demonstrates that storage hydropower is a clean energy source,and that vigorous development of pumped storage power plants can effectively save energy and reduce emissions,and provides data support for the low-carbon construction of pumped storage power plants.
