Thanks Brother Mac for keeping this clean coal story on the front burner where it needs to be . (One report that I read claimed that this process prevented 99% of emissions from escaping.)  It adds only a minimal cost to coal burning.

'In chemical looping, coal doesn’t react with air. Instead, it’s exposed to oxygen-bearing materials such as iron oxide. The coal reacts with these materials, and the energy bound up in coal breaks the bond between the oxygen and the iron. The reaction produces nearly pure carbon dioxide gas and iron metal (along with the mineral wüstite). Electricity is generated when the iron is moved out of the reaction chamber and is essentially burned—that is, allowed to react with oxygen in air. This releases heat to produce steam.

This rather convoluted process has at least two advantages. It produces a pure stream of carbon dioxide that’s easy to capture and ready to be stored underground. And the burning of iron in air also takes place at lower temperatures that don’t produce nitrogen oxide.'
