"Honda has unveiled its FCX fuel cell concept car at the Tokyo show (see this previous article for more background info). This car has a home refueling unit that also supplies electricity and hot water for the home. The 'home energy station' generates hydrogen from natural gas supplied to households, according to Honda. The system refines natural gas to provide the vehicle with hydrogen, which is mixed with oxygen to power the car. It can also supply electricity to the home and recover heat during power generation for domestic water heating. The FCX also boasts the lowest floor platform in the world by accommodating a motor, hydrogen tank and other components vertically."
