Horizon Fuel Cell Technologies is readying an electric bike that gets its energy from a rather than a rechargeable battery, according to Taras Wankewycz, co-founder and vice president of Horizon. The company is talking with government officials in both countries to get these bikes out in 2007, he added.
"About 10 millionin China get sold every year and the lead acid batteries get discarded all the time," Wankewycz said.
The company is also trying to prime interest for hydrogen-powered fishing boats, mini-cars, golf caddies and toys.
Rather than try to develop hydrogen cars, Horizon is attempting to keep the idea of hydrogen power alive by showing how fuel cells can power smaller items.
Horizon's H-racer, a hydrogen-powered remote-controlled car for hobbyists, for instance, comes with a solar panel that harvests electricity that gets utilized to split water to create hydrogen.
"The reason it works is that people can refill it," Wankewycz said. "We think big but we start small. We want to see the larger applications but we are realistic about when they are going to hit."
Even hydrogen proponents admit it's somewhat easy to come up with reasons the hydrogen economy may never come to pass. Hydrogen can be expensive to make, and production can , a greenhouse gas.is possible, but these methods remain expensive for generating large volumes of gas. Hydrogen power also is not as efficient as simply using solar power to recharge batteries.
Hydrogen, however, does have this over batteries: it takes only a few minutes to refill a gas cylinder or a tank in a hydrogen car, according to, among others, U.C. Berkeley researcher Tim Lipman. A battery, particularly a large automotive battery for an electric car, can take hours to recharge. Batteries are also expensive and need to be replaced at some point, thereby creating toxic waste. (Hydrogen fuel cells and batteries essentially perform the same task--they generate electrons for an electric engine--but harvest and deliver those electrons in a different manner.)
Until some of these problems can be ironed out, Horizon is trying to zero in on scenarios that can skirt the difficulties. One application Horizon has hopes for is powerboats. Switzerland has banned gas engine boats in many of its lakes. "You can only sail or use a battery," he said. Horizon has created, and has been testing, a hydrogen-powered trolling motor in that country. It's silent and can pull a boat forward at a low speed, two things fishermen want.
Docks typically also sell propane and other gases, so getting hydrogen in the mix should be somewhat feasible.
