Production of concentrated CO2 and electricity from a hydrocarbon feedstock by introducing an air feed stream and a methane fuel feed stream to an autothermal reactor (ATR) to produce synthesis gas, withdrawing a synthesis gas stream from the ATR and heat exchanging with a water stream to produce steam and heat exchanging the synthesis gas stream with a process stream to produce superheated steam. If necessary, steam is introduced to the synthesis gas stream before passing to a shift converter where synthesis gas reacts with steam to generate additional CO2 and H2. A shift converted gas stream is withdrawn from the shift converter and heat exchanged with a process stream to produce superheated steam. The shift converted gas stream is passed to a CO2 separation unit to separate a concentrated CO2 stream from a H2 stream, and the H2 stream is combusted in a gas turbine to produce electricity.
