In terms of fuel cost per 1km (i.e. the daily economy of driving a vehicle), a diesel vehicle costs 62% of a gasoline vehicle (equivalent class), whereas FCEV and electric vehicles cost 54% and 36% respectively. In other words, FCEV are more economical than vehicles powered by conventional internal combustion engines, but they are less so than electric vehicles.
One thing to remember is that the hydrogen energy sector is still in its infant stage. When it starts to enjoy the benefits of scale economy on the supply side, more advanced transportation and production technology for hydrogen emerge on the market, and the increased number of market participants drive hydrogen prices down, FCEV will become much more economically feasible.
