Researchers say they have produced hydrogen from ethanol in a prototype reactor small enough and efficient enough to heat small homes and power cars.
The development could help open the way for cleaner-burning technology at home and on the road.
Current methods of producing hydrogen from ethanol require large refineries and copious amounts of fossil fuels, the University of Minnesota researchers said.
The reactor is a relatively tiny 2-foot-high apparatus of tubes and wires that creates hydrogen from corn-based ethanol. A fuel cell, which acts like a battery, then generates power.
"This points to a way to make renewable hydrogen that may be economical and available," said Lanny Schmidt, a chemical engineer who led the study. The work was outlined in Friday's issue of the journal Science.
