schwit1 (797399) writes "The clean coal technique was developed by scientists at Ohio State University, with just $5 million in funding from the federal government, and took 15 years to achieve. The process removes 99 percent of the pollution from coal.
Retrofitting existing power plants with the new process would be costly, but it would cut billions of tons of pollution. The process, called “coal-direct chemical looping,” has been proven in a small scale lab at OSU. The next step is to take it to a larger test facility in Alabama. The technology generated 25 kilowatts of thermal energy in current tests; the Alabama site will generate 250 kilowatts."
