Ford Motor has built a drivable prototype of a plug-in hybrid electric vehicle that uses no petroleum fuel and emits only water vapor from its exhaust pipes.
The vehicle, based on the company’s recently launched Edge crossover SUV, called the Edge HySeries.

Ford will build at least one more but has no immediate plans to put the machine into production.
The vehicle runs 25 miles on a fully charged lithium-ion battery pack, which is recharged as needed while underway by a hydrogen fuel cell on the vehicle. Total range, Ford says, is 225 miles.
It’s the second plug-in electric hybrid shown in quick succession by Detroit automakers. General Motors exhibited the Chevrolet Volt plug-in hybrid prototype, a small sedan.
If put into production, plug-in hybrids recharge overnight while plugged into a common household outlet. That would be enough for a day’s driving by most users. If not, onboard recharging systems would kick in while driving.
The striking feature about the Edge HySeries is that its onboard recharger is a hydrogen fuel cell, eliminating the need for a pollution-producing petroleum engine.
GM’s Volt uses a 1-liter gasoline engine to recharge the batteries, a Volt would go 40 miles before the battery needs a charge.
Depending on whose studies are used, most users drive less than 30 or 40 miles a day, so they would seldom need to tap the recharging source in the vehicles. They could simply plug them in at night and be ready to go again in the morning.
