Since its gasification process allows for the separation and capture of CO2 before combustion, the gas is still in a relatively concentrated and pressurized form. Pulverized coal plants can only capture CO2 after combustion, when it is far more diluted and harder to separate, increasing the costs of implementing CCS.

Integrated coal gasification combined cycle (IGCC) plants are an example of the hydrogen route. Coal is gasified to form synthesis gas ( syngas) of CO and H 2. The gas then undergoes the watergas shift, where the CO is reacted with steam to form CO 2 and H 2. The CO 2 is then removed, with the hydrogen being sent to a gas turbine combined cycle.

Mankind is currently in the process of altering the chemistry of the global atmosphere. Atmospheric CO 2 concentrations have been increasing as a direct result of human activities such as deforestation and the burning of fossil fuels (, coal and oil). Over the past 150 years, CO 2 concentrations in the atmosphere have increased by as much as 30% (from 280 to 370 ppm; Figure 1).

Pre combustion process is related to the treatment of synthesis gas (syngas) composed principally of CO and hydrogen [6].Precombustion rate is premised on the production of syngas, removal of CO 2 and combustion of H 2 [7].In some ways it is oxymoron because CO 2 is obviously not normally available for capture prior to combustion, as CO 2 is a product of coal combustion, not a natural precursor.

CO 2 capture. In the precombustion capture process, fuel reacts with O 2 and H 2 O. During the reaction, the carbon in the fuel is converted to CO 2 and CO, and simultaneously, H 2 is produced. After the watergas shift (WGS) reaction, CO is converted into CO 2, and the main components in the mixed gas (namely, syngas) are approximately 6080% H 2 and 2040% CO 2 [21].
