本文比较了天然气（NG）为基础的燃料的温室气体（GHG）排放量与电动汽车（EV）的GHG排放量与天然气发电在中国。生命周期模型用于计算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。与汽油车相比，由天然气发电而不使用二氧化碳捕获和储存（CCS）技术的电动汽车的生命周期温室气体排放量减少了36%-47%。减排潜力的大范围变化是由中国未来可能用于发电的不同发电技术驱动的。当CCS用于发电厂时，与汽油车辆相比，温室气体排放减少量增加到约71%-73%。压缩天然气（CNG）和液化天然气（LNG）燃料与汽油车相比，可以节省约10%的碳。然而，通过费托合成法生产的气转液（GTL）燃料可能会导致生命周期温室气体排放量增加，可能比汽油高3%-15%，但大致相当于石油基柴油。当使用CCS时，从生命周期的角度来看，GTL燃料汽车的温室气体排放与石油基柴油燃料高效混合动力汽车大致相同。
This paper compares the greenhouse gas (GHG) emissions of natural gas (NG)- based fuels to the GHG emissions of electric vehicles (EVs) powered with NG-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. The reduction of life-cycle GHG emissions of EVs charged by electricity generated from NG, without utilizing carbon dioxide capture and storage (CCS) technology can be 36%–47% when compared to gasoline vehicles. The large range change in emissions reduction potential is driven by the different generation technologies that could in the future be used to generate electricity in China. When CCS is employed in power plants, the GHG emission reductions increase to about 71%–73% compared to gasoline vehicles. It is found that compressed NG (CNG) and liquefied NG (LNG) fuels can save about 10% of carbon as compared to gasoline vehicles. However, gas-to-liquid (GTL) fuel made through the Fischer-Tropsch method will likely lead to a life-cycle GHG emissions increase, potentially 3%–15% higher than gasoline, but roughly equal to petroleum-based diesel. When CCS is utilized, the GTL fueled vehicles emit roughly equal GHG emissions to petroleum-based diesel fuel high-efficient hybrid electric vehicle from the life-cycle perspective.
