Energy consumption, emission and economy analysis of fuel cell vehicle in China

Abstract

Abstract Compared with internal combustion engine vehicles and electric vehicles, the advantages of fuel cell vehicles are still in a qualitative stage, and there is no clear quantitative analysis. In this paper, the energy consumption and emission results of twelve different hydrogen paths are calculated through the secondary modeling in GREET, and the total energy consumption and emissions of fuel cell vehicles, internal combustion engine vehicles, and electric vehicles are obtained. The results show that electric vehicles have the lowest energy consumption throughout their life cycle, and fuel cell vehicles are only about 22% higher than electric vehicles. At the same time, based on the analysis of multi-factor environmental indicators such as global warming potential, human toxicity potential, photochemical smog potential, aerosol potential and acidification potential, fuel cell vehicles have the lowest life cycle emissions. Finally, a comparison of the total cost of ownership of the three representative vehicles shows that the cost of fuel cell vehicles is the highest under current production. However, combined with the analysis of the cost reduction space of the main components of the fuel cell system, the results show that when the mileage is higher than 56,000 kilometers, The total cost of ownership of fuel cell vehicles will be lower than internal combustion engine vehicles.
