Abstract
In this paper, the technical and economic feasibility of Solid Oxide Fuel Cell-Battery Hybrid Vehicles is studied based on Iran conditions and compared against Polymer Electrolyte Fuel Cell (PEFC) Vehicles, Battery Electric Vehicles (BEV) and Gasoline Vehicles. Existence of enormous resources of natural gas and its extensive distribution and transmission lines in Iran are a great opportunity to develop SOFC-Battery hybrid vehicles fueled by natural gas. In this paper, energy consumption and greenhouse gas emissions and life cycle cost were analyzed. We ranked different vehicles in 2021 and forecast their ranking for 2030, which is crucial for policymaking and technology support. The results show the well to wheel energy consumption of SOFC-Battery hybrid vehicle per km in 2021 is nearly same as PEFC FCEVs and 1060 kJ and 560 kJ less than gasoline and battery electric vehicle respectively. The well to wheel emission of SOFC FCEVs in 2021 is a little less than PEFC FCEV and 50% and 28% lower, respectively than gasoline vehicle and BEV. It is expected that the life cycle cost per km on a charge of SOFC hybrid vehicles with equal driving range will be the best choice in 2030 with 23.9 cents per km.
