Outline
With the popularization of electrification of passenger cars, its powertrain has also developed from a single Internal Combustion Engine (ICE) to a hybrid power, pure electric and hydrogen fuel cell power and hydrogen ICE power. In the Life Cycle Assessment (LCA) mode, the vehicles matched different powertrains will produce different quantity of CO2. According to the CO2 composition and preparation methods of electric energy and hydrogen energy in China, the CO2 emission for the consumption of unit electric power and unit hydrogen is calculated separately, and the actual CO2 emission value of passenger cars of different models and different powertrains is calculated. According to the calculation results, under LCA mode, (1) pure electric powertrain can reduce CO2 emissions by 48%~57% compared with a single ICE powertrain at normal temperature; (2) CO2 emission can be reduced by 31%~44% at low temperature; (3) under the current mode of hydrogen production, storage and transportation, the CO2 emission of hydrogen fuel cell power is 10% lower than that of Hybrid Electric Vehicle, and is 1.5~1.6 times that of pure electric vehicle.
