摘要
为了分析电动汽车和氢动力汽车在中国的应用前景,使用从油井到车轮的生命周期评价方法,对以煤基原料提供动力的电动汽车和氢动力汽车的循环的生命周期化石能消耗和温室气体排放进行了对比。结果表明:从全生命周期的角度看,未采用CO2捕集与封存技术时,电动汽车在生命周期化石能消费和温室气体排放方面优势明显。随着CCS技术的大规模商业化,氢动力汽车的全生命周期温室气体排放将优于电动汽车,但这需要以生命周期化石能消费的增加为代价,中国政府有必要加大对电动汽车的关注。
The potential for using electric and hydrogen powered vehicles in China was analysed in this paper. The fossil energy consumption and green house gases （GHG） emissions of these two kinds of vehicles based on coal feedstock were compared based on life cycle analysis method. The results show that the electric vehicles have significant advantages over hydrogen vehicles both in well-to-wheel fossil energy consumption and in green house gases emissions if COz capture and sequestration （CCS） is not widely applied. Since CCS become widely commercialized, hydrogen powered vehicles then have an advantage in well-to-wheel GHGs at the sacrifice of fossil energy consumption. Therefore, the Chinese government should pay more attention to the development of electric vehicles.
