Abstract: Clean-energy vehicles are conducive to reducing greenhouse gas emissions and environmental pollution. The environmental assessment of hydrogen fuel cell vehicles (FCV) and natural gas vehicles (NGV) under different fuel production paths can achieve efficient utilization of renewable energy and reduce environmental pollution. This study conducted a life cycle assessment on hydrogen FCV and NGV under different fuel production paths. The results indicated that compared with NGV, hydrogen FCV exhibit better environmental performance. Among the fuel production methods, wind-power-assisted electrolysis of water for hydrogen production exhibits superior environmental performance. The acidification potential, global warming potential, eutrophication potential, and photochemical ozone creation potential indicators of the wind-powered fuel cell vehicles process were 91.44, 73.33, 96.47, and 93.39% lower than those of the coal synthetic natural gas vehicles process, respectively. Subsequently, the environmental impact of the internal structure in the manufacturing process of hydrogen FCV and NGV was investigated. The results showed that the power system accounted for nearly 50% of the environmental impact in the manufacturing process of hydrogen FCV. Furthermore, the influence of the six methods used for fuel production on environmental performance was evaluated through sensitivity analysis. This study provides a reference for the sustainable development of such vehicles.
