Hydrogen is a clean energy source. It produces zero emissions when burn in the presence of air. Hydrogen (H2) can also be utilized as a fuel in so many applications such as for power production, space, and automobile. In this paper, the technology of hydrogen as a green fuel for the vehicles is described. In this paper, it is assumed that the hydrogen is produced by five different types of electrolyzers using water electrolysis technology. This produced H2 is utilized in five different types of fuel cell electric vehicles having a driving range of 40 km per day. If gasoline vehicles are used for same driving range, CO2 emissions are calculated and CO2 emission savings from fuel cell electric vehicles (FCEVs) are calculated. 130 g CO2 emission per km is assumed for the study. Life cycle fuel cost of vehicles using petrol, diesel, and fuel cell is also estimated for 15 years life. It was found that the life cycle total fuel cost of the vehicles is in the order of Tucson > Petrol > Diesel > Toyota > Mercedes > Hyundai > Honda with maximum cycle cost was of Tucson, and minimum cycle cost was of Honda. Two ways for improving CO2 emission targets are suggested. First one is by considering some percentage (25%, 50%, or 75%) of total number of vehicles are FC vehicles and remaining are conventional vehicles. Second one is by improving the fuel economy of conventional vehicles. If 25%, 50%, or 75% of total number vehicles are FC vehicles and remaining are conventional vehicles, CO2 emissions are predicted. If all the vehicles are conventional vehicles and no FC vehicles are present, then to achieve same targets of CO2, improvement of 133%, 200%, and 400% in fuel economy of conventional vehicles is required.
