典型电力电缆碳足迹核算与减排分析

Carbon Footprint Accounting and Emission Reduction Analysis of Typical Power Cables

采用全生命周期评价方法,以生产1 m 110 kV 1×800电缆为功能单位,构建了“从摇篮到大门”的电缆生产碳足迹核算模型。调研国内知名企业的电缆生产数据,以此为基础,利用Simapro软件并结合Ecoinvent数据库,对该典型电力电缆开展了碳足迹核算和减排措施分析。结果表明:生产1 m的110 kV 1×800电缆碳足迹为48.92 kgCO2eq,其中原材料生产阶段的铝带生产带来的碳排放量占产品生命周期碳足迹的52.6%,应作为减排的关注重点。为此,可通过采用回收铝来将该阶段的碳排放量降低11kgCO2eq。同时,其他类型原材料自身碳足迹以及电力电缆在生产阶段的电力用能同样也应成为减排重点,进行深入挖掘,以便全面降低该型电缆的碳足迹。

By means of the whole life cycle evaluation,a carbon footprint accounting model of cable production from“cradle to gate”is constructed with the production of 1m 110 kV 1×800 cable as the functional unit.On the basis of the research data of the cable production of well-known domestic enterprises,Simpro software in conjunction with the Ecoinvent database is used to analyze the carbon footprint calculation and emission reduction measures for this typical power cable.The research results show that the carbon footprint of 1m 110 kV 1×800 cable is 48.92 kgCO2eq.In this footprint,the carbon emissions caused by the production of aluminum strip in the production stage of raw materials account for 52.6%of the carbon footprint of the product life cycle,which should be the focus of emission reduction efforts.To this end,carbon emissions at this stage can be reduced by 11 kgCO2eq by using recycled aluminum.At the same time,the carbon footprint of other types of raw materials and the power consumption of power cables in the production stage should also be the focus of emission reduction,and in-depth digging should be carried out in order to comprehensively reduce the carbon footprint of this type of cable.
