But what about the energy requirements of this process? I note that the it involves heating the Calcium hydroxide (calcium bicarbonate or Calcium carbonate I would have thought – High School chemistry) to 900 degrees C to drive off the CO2 and regenerate the Calcium hydroxide [Ca(OH0)2]

This is going to require a considerable amount of energy, the generation of which could conceivably involve further CO2 emissions. In order for this to work, you’d need to virtually duplicate the existing power generation infrastructure to supply the energy needed to regenerate the Ca(OH)2.

Whilst technically feasible, how can it work in practice?
