Honda’s FCX hatchback uses hydrogen to generate electricity that powers the vehicle. “We are the only manufacturer that has this car,” says Honda. “There are 20 driving around, mainly in America and Japan. It is not a concept, it is a real certified car and it makes sense to bring it to Britain.” 

The ideal family would be one that typifies British car users, driving the vehicle to work, on shopping trips and on holiday. Honda is reluctant to go into detail because it has not made a final decision and may yet conclude the project is too costly. But if the plan goes ahead it is expected that the chosen household would be provided with its own refuelling station; possibly Honda’s home energy station, which uses natural gas to generate hydrogen.
