本文对中国煤制油（CTL）燃料的温室气体排放与煤电驱动的电动汽车（EV）的温室气体排放进行了比较。生命周期模型用于考虑整个燃料循环和使用阶段的排放，以及车辆循环和电池制造排放。研究发现，与石油汽油汽车相比，在不使用二氧化碳捕获和储存（CCS）技术的情况下，使用煤炭发电的电动汽车的生命周期温室气体排放量可减少3%至36%。巨大的减排潜力是由许多不同的发电技术驱动的，这些技术现在和将来可能用于中国发电。当发电厂采用 CCS 时，与石油汽油汽车相比，温室气体排放量减少 60-70%。然而，使用煤炭生产液体运输燃料（CTL 燃料）可能会导致生命周期温室气体排放量显着增加，可能比石油基汽油高出 30-140%。当 CTL 工厂采用 CCS 时，从生命周期的角度来看，CTL 燃料车辆排放的温室气体排放量与石油基汽油车辆大致相同。作者得出的结论是，中国需要制定政策，以加速电动汽车充电的电池技术和基础设施改进、加强能源效率管理以及CCS等低碳技术的部署。
This paper compares the GHG emissions of coal-to-liquid (CTL) fuels to the GHG emissions of electric vehicles (EVs) powered with coal-to-electricity in China. A life cycle model is used to account for full fuel cycle and use-phase emissions, as well as vehicle cycle and battery manufacturing emissions. It is found that the reduction of life cycle GHG emissions of EVs charged by electricity generated from coal, without utilizing carbon dioxide capture and storage (CCS) technology can be 3–36% when compared to petroleum-based gasoline car. The large range in emissions reduction potential is driven by the many different power generation technologies that are and could in the future be used to generate electricity in China. When CCS is employed in power plants, the GHG emission reductions increase to 60–70% compared to petroleum-based gasoline car. However, the use of coal to produce liquid transportation fuels (CTL fuels) will likely lead to significantly increased life cycle GHG emissions, potentially 30–140% higher than petroleum-based gasoline. When CCS is utilized in the CTL plant, the CTL fueled vehicles emit roughly equal GHG emissions to petroleum-based gasoline vehicles from the life cycle perspective. The authors conclude that policies are therefore needed in China in order to accelerate battery technology and infrastructural improvements for EV charging, increased energy efficiency management, and deployment of low-carbon technologies such as CCS.
