摘要
通过应用全生命周期分析方法,本文对各种代用燃料的CO2排放和有害排放进行了全面分析,为未来大规模推广会造成的环境影响给出量化评估结果。研究表明,煤基代用燃料CO2排放和有害排放都较高;电动汽车能减少油箱到车轮阶段的CO2和有害排放,但发电过程中大量使用煤炭又会造成大量的环境污染;汽油车温室气体排放量高,柴油车有害气体排放量大,在短期如果没有法规的限制和技术进步将会进一步影响环境;燃料电池是最清洁的能源形势,无论WTT阶段和TTW阶段,CO2和有害气体排放都很少。
Because of the shortage of petroleum and worsen of environment,the petroleum fuel faced the energy and environment challenge.The demand of alternative fuel increased rapidly.Although the using of alternative fuels on vehicle was carried on but the environment assessments of them were not studied yet.Based on life cycle assessment method,this paper gave the details of CO2 and harmful emissions of alternative fuels and supplied the data for the future application.The results told that coal-based fuels released the highest CO2 and harmful emissions both.Electrical vehicle gave no emissions during the using period,but the origin of electric released a lot of emission because of the using of coal.The emission of fuel cell vehicle was considerable low either the production period and using period.
