We take a coal price of around 65 / Ton. The cost of coal consumed by 100 MW power plant is ( x 65) 3497 /hr. A 100 MW unit produces 100,000 units of electricity. So the cost of coal per unit of electricity is (3497/100,000) cents per unit. The cost of fuel is the main factor in the cost of a unit of electricity.
The excellent performance of oxycoal combustion power plant has been observed in term of its ability to capture carbon dioxide with 95 % purity and 96 % recovery rate. .
