To scientifically assess the application potential of carbon neutral fuels in vehicle power systems and support the low-carbon transition of the transportation sector, the paper integrates cutting-edge technological advances and industry research findings to innovatively construct a Fuel Evaluation System (FES) applicable to automotive power systems. Hydrogen, ammonia and methanol are selected as research subjects, while gasoline, diesel and natural gas are taken as comparative samples. A comprehensive assessment is conducted from 4 dimensions: fuel safety, production, storage, transportation and refueling, and technological research reserve. Additionally, a life-cycle carbon emission analysis of the fuels is supplemented. The results indicate that methanol and ammonia are currently the preferred carbon-neutral fuels for near-term promotion and application. Meanwhile, hydrogen fuel exhibits considerable potential and promising prospects, its widespread adoption is currently hindered by significant technical challenges pertaining to storage, transportation, and refueling safety.
