At some point in the near future, fuel cell technology being developed for automobiles could be used to power our homes.

Another possibility that comes from such a system is the homeowner's ability to power the house from a fuel-cell vehicle. The fuel cell in a typical fuel-cell vehicle would have an output power from 25 kW to more than 100 kW. Because the average home only uses between 2 and 10 kW of electricity, it would be possible to "plug" the car into the home to provide power from the fuel cell using the hydrogen stored on the vehicle.
