Won’t the cost of hydrogen be greater than that of gasoline?
If we use current electrolysis technology, the cost of hydrogen is estimated to be about 70% greater than the cost of gasoline. ($2.5/kg, where 1kg=energy in 1 gallon of gasoline) With new technologies, however, such as high temperature steam decomposition, the costs are expected to become comparable. Furthermore, as the supply of gasoline becomes more limited, the price of gasoline will only increase beyond current levels. In the past year, the price of oil has increase for $25/barrel to over $50/barrel.
