Using Rust to Capture CO2 from Coal Plants

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.

Chemical looping could be a big improvement over systems for capturing carbon dioxide from conventional power plants. The typical systems reduce the power output of coal plants by as much as 30 percent and, because of the reduced power output and the cost for additional equipment, increase the cost of electricity by 85 percent.
