1. A method for generating energy, the method comprising:
partially combusting a hydrocarbon fuel and providing a hot combustion gas stream, the combustion gas stream comprising hydrogen (H2), carbon dioxide (CO2) water and carbon monoxide (CO);
at least partially separating the water from the combustion gas stream and providing CO/CO2/H2 streams;
at least partially separating the hydrogen from the combustion gas stream to provide a CO/CO2 stream and a hydrogen stream;
at least partially separating the CO from the CO/CO2 stream and providing a CO stream;
completely combusting at least a portion of the CO stream and providing a source of CO2 working fluid; and
introducing said source of CO2 working fluid to at least one expander unit for receiving and expanding the source of CO2 working fluid; the at least one expander unit coupled to at least one turbine configured to generate energy.
