The secret appears to be in the heating of the coal rather than the burning of the coal. This allows for the recycling of the carbon dioxide within a “Coal-Direct Chemical Looping”, (CDCL) system that captures the carbon dioxide. The Department of Energy standards requires a 90% capture rate, at OSU testing there has been a 99% capture rate, far exceeding the EPA standards.
