text: Conversion of a conventional coal-fired power plant is done by injecting the  into ammonium carbonate after which it is then transported and deposited underground (preferably in soil beneath the sea). This injection process however is by far the most expensive. Besides the cost of the equipment and the ammonium carbonate, the coal-fired power plant also needs to use 30% of its generated heat to do the injection (parasitic load). A test-setup has been done in the American Electric Power Mountaineer coal-burning power plant.
  One solution to reduce this thermal loss/parasitic load is to burn the pulverised load with pure oxygen instead of air.
