Abstract: A gas turbine system includes an exhaust gas processing system that includes an exhaust stack having a first inlet and a first outlet. The first inlet is fluidly coupled to a second outlet of a cooler configured to direct the exhaust gas to the exhaust gas processing system via a first conduit extending between the exhaust stack and the cooler. The first conduit includes a first end configured to be directly coupled to the second outlet of the cooler and a second end configured to be directly coupled to the first inlet of the exhaust stack. The exhaust gas processing system also includes a carbon capture system disposed within the exhaust stack and configured to receive a carbon dioxide (CO2) lean solvent, to remove CO2 from the exhaust gas, to generate a CO2-rich solvent comprising the CO2 removed from the exhaust gas, and to generate a treated exhaust gas.

Abstract: Some embodiments are directed to a hybrid combustion turbine power plant including a conventional gas turbine, integrated via a fluid connection allowing air injection or extraction, with an adiabatic compressed air energy storage system (ACAES) including a direct TES (thermal energy store) and, downstream thereof, a supplementary compressor and pressure reducing device disposed in alternative pathways between the direct TES and compressed air store. The ACAES discharges air into the gas turbine via the fluid connection at a desired mass flow rate through the pressure reducing device, and charges with air via the supplementary compressor at a lower mass flow rate over a longer period of time, trickle charging allowing the use of a low power supplementary compressor. The use of a direct TES (40) efficiently returns the heat of compression. Alternatively, variable mass flow, reversible power machinery and a second TES may be provided downstream of the direct TES.

Abstract: A fuel oxidizer system is operated in a first operating mode. In the first operating mode, a mixture that includes fuel from a fuel source is compressed in a compressor of the fuel oxidizer system; the fuel of the compressed mixture is oxidized in a reaction chamber of the fuel oxidizer system; and the oxidized fuel is expanded to generate rotational kinetic energy. The fuel oxidizer system is operated in a second operating mode. In the second operating mode, fuel from the fuel source is directed to bypass the compressor, and the fuel that bypassed the compressor is oxidized in the reaction chamber.

Abstract: Cryogenic energy storage systems, and particularly methods for capturing cold energy and re-using that captured cold energy, are disclosed. The systems allow cold thermal energy from the power recovery process of a cryogenic energy storage system to be captured effectively, to be stored, and to be effectively utilized. The captured cold energy could be reused in any co-located process, for example to enhance the efficiency of production of the cryogen, to enhance the efficiency of production of liquid natural gas, and/or to provide refrigeration. The systems are such that the cold energy can be stored at very low pressures, cold energy can be recovered from various components of the system, and/or cold energy can be stored in more than one thermal store.

Abstract: The invention is directed to a process to obtain a compressed gas starting from a starting gas having a lower pressure by performing the following steps: (i) increasing the pressure and temperature of a gas having an intermediate pressure by means of indirect heat exchange against a fluid having a higher temperature to obtain a gas high in pressure and temperature, (ii) obtaining part of the gas high in temperature and pressure as the compressed gas, (iii) using another part of the gas high in temperature and pressure as a driving gas to increase the pressure of the starting gas in one or more stages to obtain the gas having an intermediate pressure for use in step (i). The invention is also directed to a configuration wherein the process can be performed and directed to a process to generate energy using the process.
