Houston Community News >> Chinese Company Starts Small Hydrogen Powered Car

7/24/2006 China-- It's a dream that's been pursued for years by governments, energy companies and automakers so far without success: Mass-producing affordable hydrogen-powered cars that spew just clean water from their tailpipes.

So Shanghai's Horizon Fuel Cell Technologies decided to start small. Really small. This month, it will begin sales of a tiny hydrogen fuel-cell car, complete with its own miniature solar-powered refueling station. The toy is a step toward introducing the technology to the public and making it commercially viable.

"Public awareness and education are the first steps toward commercialization," said Horizon founder Taras Wankewycz, 32. "We want to make sure this technology gets adapted globally."

Automakers and energy companies view hydrogen fuel cells as a promising technology that could wean the world from its addiction to crude oil. But it's expensive and technological hurdles remain despite billions of dollars that have been poured into research.

There's the cost and challenge of building fuel cells that convert hydrogen to electricity, and the question of how to cleanly generate the gas and distribute it to yet-to-be built fueling stations. Though prototype hydrogen cars exist, they're far from practical or affordable.

Horizon's H-Racer and fueling station solve those problems on a very small scale. The price: $80 for the set.
The toy's fuel cell, like those envisioned for real cars, relies on an electrochemical reaction to generate the current that powers the gadget's electric motor. Unlike a gas-powered internal combustion engine, the only byproducts are electricity, heat and water.

The fuel is supplied by its alarm clock-sized refueling station. A small electric current, generated by the solar cells, extracts hydrogen from water. (A battery backup is available for cloudy days.)

When the vehicle is hooked up to the refueling station, a balloon inside the 6-inch long car slowly fills.

With the flip of a switch, the car takes off and runs for 4 minutes on a full tank. The gas never ignites -- and any would-be re-creators of the Hindenburg disaster are likely to be disappointed by the toy's negligible amount of the gas.

Horizon has bigger plans for the technology. Wankewycz said it's working on ways to make fuel cells more efficient, so that they can be used to power cell phones and laptop computers, and eventually vehicles and households. Still, what works for a toy isn't close to being ready for full-size cars. For one, it's extremely expensive, said Daniel Nocera, a Massachusetts Institute of Technology chemistry professor and one of the world's leading researchers in exploring how sunlight can be used to extract hydrogen from water.

"Technologies exist to split water with solar cells," he said. "It's just not market-viable yet. ... To say that it's going to be upscaled or commercialized for an energy society, that's a leap of faith for me."

Still, he admires Horizon's raising awareness about alternative energies through a toy.

Wankewycz, who was born in France but raised in California, says the company has raised about $5.5 million from venture capitalist investors since it was founded in 2003. Horizon's revenues in 2005 were $170,000 but are forecast to exceed $3 million this year, the company said.

Bigger fuel cell companies like Canada's Ballard Power Systems are working with governments in Europe, the United States and large Chinese cities like Beijing and Shanghai to build fuel-cell demonstration programs for buses and other public transport.

Horizon envisions neighborhood systems of small shops providing refills for small hydrogen canisters to families, much as they now sell tanks of liquid petroleum gas or propane for stoves and heaters. The canisters could be used to power scooters or small, electric cars suitable for short jaunts, Wankewycz said.

Horizon also is selling thousands of educational science kits that retail for about $50, and it's marketing fuel cell stacks for research purposes. It also hopes to commercialize its fuel cell technology for short-term emergency use, such as powering cell phones in a disaster.
