product: hydrogen scooter
context: just about everybody agrees that, to contribute to reducing air pollution, we would be better off using hydrogen instead of gas for fuel. For starters, hydrogen makes water vapour instead of carbon monoxide when it's burned. But building a safe, efficient hydrogen vehicle is another matter…
product: ‘AQWON’, the first hydrogen powered zero-emission-scooter worldwide, was officially presented at the Hannover Messe Industrie (German fair) in 2003. This 2-stroke scooter has received technical approval from the German TÜV*. AQWON’s top speed is about 50 km/h (30mph), power is 2,6 kWh and weight is minimal.
how it works: the biggest challenge was building a fuel tank that could safely store the hydrogen. The scooter’s inventor solved this problem by developing a 50 bar pressure tank to store the hydrogen safely. In case of an accident, the tank freezes and no fire or explosion occurs. Anybody, without any special skills, can fill up the tank within 3 to 4 minutes, without being in any danger. A pressure sensor transmits data to a computer chip, which then accumulates and sends the necessary information regarding the proper hydrogen mixture to the injection jet. This refilling process is possible through a newly developed system consisting of pressure tanks and a hydrogen generator. The whole system works with solar power and water to produce hydrogen for your personal use.
other producers: the good news is that after the German pioneers, other producers have been developing their own zero-emission scoters. Here below are a few examples:
Thanks to all these efforts, green ‘scootering’ is already more than a dream!
- In August 2004, Honda developed its fuel cell scooter [www.hydrogennow.org/HNews/PressReleases/
Honda/HondaFC_Scooter.htm] and is now planning to refine the new vehicle’s design to make it even lighter and more compact.
- In November 2004, Samsung Engineering announced the successful test ride of a hydrogen-powered motorcycle [www.fuelcellsworks.com/Supppage1542.html]. The scooter can run for up to 140 kilometres on 6 litres of hydrogen fuel. The newly developed technology uses a water-based solution of sodium borohydride, made from sodium borate, to produce hydrogen gas. On 6 litres of hydrogen fuel, the vehicle can travel three times farther than a scooter powered by a nickel-cadmium cell. The downside is that there are only about 300 million tons of sodium borate worldwide, located mostly in Tibet, and that annual global production of sodium borohydride stands at 10,000 tons.
- In January 2005, as part of India's hydrogen energy programme, Indian scientists built a hydrogen motorcycle, which will soon be tested in Delhi. Scientists are working in the area of fuel cells in which hydrogen and oxygen combine to produce electricity and water.
