ah kind of sportbike'ish:
The ENV H2 motorcycle uses CORE cell technology, which contains the hydrogen and battery components in one unit and is removable from the motorcycle. The Intelligent Energy ENV, with its 6kW, 48 volt motor and 1kw fuel cell, has a top speed of 50 mph and a range of 100 miles. The speed and range are expected to be increased by the time the ENV reaches its production version.
In order to reach peak acceleration, power is drawn from both the fuel cell and battery pack as needed. The ENV also uses disc brakes and a belt drive system for better control and traction. According to Intelligent Energy, the ENV is one of the first hydrogen motorcycles designed from the ground up rather than relying on previous technology.
The Intelligent Energy ENV will most likely be the first H2 vehicle to be mass-marketed to the public. It is expected to sell for $6,000 to $8,500 when it rolls out in the latter part of 2006. The British company has also decided to move their headquarters to California, which has 16 hydrogen refueling stations throughout the state (and is expected to have 100 stations by the year 2010) in order to be closer to their target market.
