Consumer hydrogen cars in five years?

That's what officials at Ford are predicting, anyway. The new cars will use internal combustion hydrogen engines- not as clean as pure fuel cell cars, but much cheaper to develop and build. Said spokesman John Laptez. "The technology is there at a sufficient level, in the three-to-five-year window, if all things were perfect, we could reasonably think this is a solution we could draw on. We're not really talking about invention, that's the thing. We know how to manufacture this kind of technology in high volumes."

But the 'all things perfect' requirement is a bit tricky- to make a run at the hydrogen market, fuel storage limitations must be solved, public fear of hydrogen allayed, filling stations set up, and gas prices must remain high.

Hydrogen combustion vehicles still produce minute amounts of harmful emissions, but drastically less than a gasoline vehicle. But the biggest benefit to hydrogen combustion is its cost and availability. They can therefore help to bridge the gap between fossil fuels and the holy grail of enviro transportation, the hydrogen fuel cell.
