Clean coal

From Freepedia

Main article: Coal

Clean coal is coal chemically washed of minerals and impurities, sometimes gasified, burned and the resulting flue gases treated with steam and reburned so as to make the carbon dioxide in the flue gas economically recoverable. The carbon dioxide will then be sequestered by some means (several are being explored - see Carbon dioxide sink).

The primary example of clean coal is the proposed US FutureGen plant - a zero-emissions coal-fired power plant.
