Using Rust To Capture CO2 From Coal Plants

From Technology Review:

Process could capture carbon more cheaply.

Researchers at Ohio State University are developing a novel process for generating electricity from coal that also promises to make capturing carbon-dioxide emissions cheaper. The work is being done with the help of a $5 million grant from the U.S. Department of Energy's new Advanced Research Projects Agency-Energy. The technology has been proven in laboratories; researchers will use the new funds to demonstrate it in a 250-kilowatt, pilot-scale power plant.
