Cooling coal emissions to result in less carbon dioxide

Refrigerating coal emissions would reduce the amount of dangerous chemicals in the air. According to research by a team of physicists from University of Oregon, it would reduce carbon dioxide emissions in particular by 90%.

The associated “energy penalty” would raise electricity use by about a quarter. This would be offset by significant benefits, such as a 38% reduction of cost to society through reduced health-care and climate-change costs thanks to cleaner air.

Cryogenic treatment would involve cooling machinery potentially the size of a football stadium. Carbon dioxide would be captured in its solid state, warmed, compressed into gas and then moved by pipeline to dedicated storage facilities hundreds of miles away.
