In all embodiments, the present invention utiliZes at least one poWergeneratingcycleproducingCO2 containingemissions andWithatleastonepoWergeneratingcycleusingsupercriti cal carbon dioxide “ScCO2” as a Working ?uid. BACKGROUND OF THE INVENTION [0002] Energyef?ciencyhasimportantimpactonbotheco nomics of operating costs and carbon dioxide “CO2” emis sions. The production of fuels from biomass often has byproducts consisting of carbon dioxide, and in most cases the carbon dioxide is at an exergy level su?icient to yield poWergeneration.One suchsourceofcarbondioxideisthe catalytic conversion of cellulosic biomass into liquid and/or gaseous fuels.Another source ofcarbon dioxide isthe com bustionexhaustofhightemperatureindustrialprocessesand/ orpoWergenerationcycles(a.k.a.topcycle).

SUMMARY OF THE INVENTION [0005] Thepresentinventionpreferredembodimentrelates to the decoupling of the high pressure side of a Waste heat driven poWer generation cycle from the loW pressure side. The utiliZation of a high pressure side storage system and a loW pressure side storage system combined With an onsite CO2 source resulting directly from either combustion exhaust or secondary process byproduct. The onsite CO2 source enables the high pressure side “high-side” to have its ScCO2 Working ?uid to be sourced from either or both the high-sidestoragetankasabufferedCO2 source(inpartor entirely such as in a compressed air energy storage), or entirely/in part from pressure increasing device (e.g., tur bocompressor, turbopump, compressor, or pump) having its source of the loW pressure side “loW-side” of the ScCO2 poWergeneratingcycle.TheabilitytoventCO2 fromeither orboththehigh-sideandloW-sideatanypointofoperationis physically enabled, but more importantly economically enabledbyutiliZingCO2 fromthesecondaryprocess.
