| The fuel-cell and Hydrogen-based propulsion | |
|
While electrical and hybrid cars are slowly replacing conventional models, the next generation of fuel-cell vehicles (FCV) are under development by leading car manufactures. These will be based on fuel-cell technology and hydrogen propulsion, and the result is cars emitting no CO2.
|
|
| How it works | |
|
A fuel-cell is effectively a battery. The electrical energy is generated by a chemical process combining hydrogen (4H2) and oxygen (O2). The result is electricity and water. The technology produces no carbon dioxide, which contributes to global warming. |

| When can I have one? | |
|
All the leading car manufactures are working on prototype models. Mercedes is testing fuel-cell buses in China, while UPS is working with American partners to test a small delivery van.

|
| Any drawbacks or problems? | |
| Yes, the technical components making up a hydrogen fuel-cell need to be reduced and improved further to ensure vehicles can store enough hydrogen for a 300 miles journey. In addition, not may petrol stations sell Hydrogen. Honda is testing a hydrogen refuelling station, which generated hydrogen from sunshine and water. But do not expect to see one near you in the short term. |

An FCV will have no large engine to content with. This means a quiet drive, while perfect balancing and handling is achieved. In addition, improved fuel economy and drivability is expected. Fuel-cell efficiency (~60%) is expected to be more than double that of a conventional vehicle.
