A concept for removing CO2 from a natural gas fired combined cycle power plant is presented. The removal of CO2 is achieved using natural gas reforming combined with a water gas shift reaction of the synthesis gas and a high-pressure absorption of CO2. This concept implies removal of the carbon from the fuel prior to combustion in the gas turbine.
