燃油与纯电动汽车流通过程中CO2排放分析

CO2 Emission of Fuel and Pure Electric Vehicle in the Process of Circulation

随着社会生产技术的不断进步及汽车保有量的不断增加,环境与能源问题日益凸显。结合国内2016年石油资源的消耗量及国家电网能源结构,对传统燃油车及纯电动汽在流通过程中CO2的排放情况进行计算。研究结果表明:若2016年全年汽车燃油消耗量的一半由电能取代,则需要新增发电量为809.6×10^9kW·h,新增部分电量占2016年全年发电总量的13.18%;为使CO2排放量降至一半,且主要把汽油车替换为电动车,需要新增电动车1.9×10^8辆,新增充电功率为570.06×10^6kW,将对现在的电网负荷提出了更高的要求;相对于传统燃油车电动化,合理减少电网结构中煤炭的使用量对于降低CO2排放有更积极的意义。

With the continuous progress of social production technology and the increasing number of vehicles,the problem of environment and energy has become increasingly prominent.Based on the consumption of oil resources in China in 2016 and the energy structure of the State Grid,the CO2 emission of traditional fuel vehicles and pure electric vehicles in the process of circulation was calculated.If half of the fuel consumption in 2016 was replaced by electricity,a additional power generation of 809.6 bill.kW·h woule be needed,which accounted for 13.18% of the total power generation in 2016.To cut CO2 emissions by half and mainly replace gasoline vehicles with electric vehicles,more than 190 million additional electric vehicles needed to be added and charging power of 570.06×10^6 kW would be increased,which put forward higher requirements for the current grid load.Compared with the electrification of traditional fuel vehicles,reasonable reduction of coal consumption in power grid structure has more positive significance for reducing CO2 emissions.
