Sugar could power hydrogen fuel cars says VTU researcher

Sugary carbohydrates could be used to produce low-cost hydrogen to power fuel cells ...

"A car with an approximately 12-gallon tank could hold 27 kilograms (kg) of starch, which is the equivalent of 4 kg of hydrogen," explains VTU. "The range would be more than 300 miles... [with] one kg of starch will produce the same energy output as 1.12 kg (0.38 gallons) of gasoline."

"It is environmentally friendly, energy efficient, requires no special infrastructure, and is extremely safe. We have killed three birds with one stone," said Zhang. "We have hydrogen production with a mild reaction and low cost. We have hydrogen storage and transport in the form of starch or syrups. And no special infrastructure is needed."

"What is more important, the energy conversion efficiency from the sugar-hydrogen-fuel cell system is extremely high â€“ greater than three times higher than a sugar-ethanol-internal combustion engine,"Zhang said. "It means that if about 30 percent of transportation fuel can be replaced by ethanol from biomass as the DOE proposed, the same amount of biomass will be sufficient to provide 100 percent of vehicle transportation fuel through this technology."[/b]
