Fuel Cells Powered by Hydrogen from Sewage

Posted on October 15, 2008

Researchers at the Oregon State University College of Engineering have discovered an efficient way to produce hydrogen from different types of biowaste, including municipal sewage. The process uses 75% less energy than the traditional water electrolysis method of producing hydrogen, and can be done at a much lower cost, making it a good candidate for hydrogen fuel production. In the lab, researchers are already close to the Department of Energy's goal of $2 to $3 per gasoline gallon equivalent for hydrogen fuel. The university describes the process like this: In these systems, naturall...
