Clean Coal: Burning Coal Without Releasing CO2

"Wattsupwiththat" is reporting:

For 203 continuous hours, they operated a scaled-down version of a power plant combustion system with a unique experimental design–one that chemically converts coal to heat while capturing 99 percent of the carbon dioxide produced in the reaction. 

This new technology, called coal-direct chemical looping, was pioneered by Liang-Shih Fan, professor of chemical and biomolecular engineering and director of Ohio State’s Clean Coal Research Laboratory. (Fan is a Distinguished University Professor and a 2012 Innovator of the Year.)

My understanding is that the world has an almost "endless" supply of coal based on current consumption. "Endless" defined as about 100 years, I suppose.  With some countries moving away from coal, "endless" might be even longer.
