An Introduction to CO2 Separation and Capture.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 water-gas 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.
