If you then bubble the CO2 laden flue gases through this slaked lime solution (http://en.wikipedia.org/wiki/Calcium_hydroxide) then to quote "It turns milky if carbon dioxide is passed through, due to precipitation of calcium carbonate."
Calcium Carbonate is the white substance that makes up the bulk of sea shells, snail shells and egg shells. It can easily be disposed of by being buried without risk...instead of the silly idea of burying CO2 gas. And in fact it is quite useful in many industrial applications (http://en.wikipedia.org/wiki/Calcium_carbonate#Uses).
This means the waste ash from the burning of the coal can then be re-used to extract the CO2 gas in order to make a commercially useful product.
This is similar to the solution that was created to remove the Sulphur from the coal plant output that was creating acid rain. This is now used to create gypsum (http://en.wikipedia.org/wiki/Flue_gas_desulfurization).

There seems to be a much simpler way to do all this.
The fly/bottom ash that is left over after burning the coal (http://en.wikipedia.org/wiki/Coal_power#Diagram) can contain up to 30% or 40% Calcium Oxide (http://en.wikipedia.org/wiki/Fly_ash). This can be turned into Calcium Hydroxide (slaked lime) by mixing it with water.
