If the Californians have a “Hydrogen Highway“, which includes self-service hydrogen pumps, and if hydrogen internal combusion engines are possible, what are we waiting for and why are we talking about fuel cells?
Wikipedia refers to claims of 20% extra power… And surely the conversion effort would more or less that for LPG… Surely we could reduce our consumption of non-renewables faster if we used the cars we already have? And can fuel cells run on ethanol? Why not tri-fuel cars (petrol, ethanol, hydrogen)?
Safety perhaps? But the Californians seem to have satisfied themselves that hydrogen can be made safe for public use.
