Ohio State University researchers say a breakfast byproduct could play a role in a new way of powering cars.

The researchers say they've found that eggshells can help produce hydrogen for fuel cells that mix the gas with oxygen to create energy for running a vehicle. Instead of exhaust, all that's emitted is water vapor.

The current process for obtaining hydrogen also produces carbon dioxide, a greenhouse gas. Ohio State engineering professor L.S. Fan says his team has found that when eggshells are added to the process, they absorb the carbon dioxide.

He says they would need to be buried afterward to keep the gas out of the atmosphere.

Fan says using eggshells also would save egg processors money now spent to dump their eggshells in landfills.
