基于能源结构与电力结构的乘用车全周期CO2排放研究

Investigation on Vehicle Lifecycle CO2 Emission Based on Energy Structure and Electricity Power Structure

基于能源结构与电力结构,研究了某型号轿车的汽油车、PHEV、EV等3款车全周期(从油井到车轮)CO2排放与尾气中CO2排放。研究结果表明:基于能源结构与电力结构现状,中国发电每生产1 kW·h的电所产生的CO2为733 g;汽油车全周期所产生的CO2为37.1g/km。全周期内,汽油车、PHEV、EV的CO2排放分别为219 g/km、161 g/km、163 g/km;汽油车、PHEV、EV的尾气中CO2排放分别为139 g/km,31 g/km,0。

The lifecycle CO2 emission(well to wheel)and tailpipe emission of gasoline-fueled vehicle,PHEV,and EV from a particular band were studied basing on the energy structure and power structure.Results show that,based on current energy and power structure in China,733 g/(kW·h)CO2 emission is from power generation process,and 37.1 g/km CO2 emission is from gasoline vehicle during its life cycle.For the selected car model with gasoline version,PHEV and EV,the lifecycle CO2 emission is 219 g/km,161 g/km and 163 g/km,respectively;and the tailpipe CO2 emission is 139 g/km,31 g/km and 0 respectively.
