摘要： A system comprising two or more thermal stores, a single store for pressurised air and a means of collecting relatively low-grade heat offers the potential for an energy storage system that achieves two desirable aims at the same time: (i) the total exergy that may be released when a given pressurised air store is discharged is maximised and (ii) the ratio between the exergy extracted and the work invested in compressing the air via a multi-stage compressor is also increased by exploiting some source of low-grade heat to augment the thermal content of several thermal stores. The system comprises a compressed air energy storage system which tends, in any one fill-empty cycle of the pressurised air store, to pump heat upwards in temperature from lower-grade stores to the highest-grade thermal store as well as a thermal capture subsystem that can augment the heat content of the lower-grade thermal stores. Some provision is also present whereby other fluid can be introduced into the expansion process in addition to the air that was compressed via the multi-stage compressor facility.

摘要： A compressed air energy storage power generation device 2 equipped with: a compressor 10 mechanically connected to a motor 30; a first pressure storage tank 12 storing compressed air from the compressor 10; an expansion device 14 driven by compressed air from the tank 12; a generator 28 mechanically connected to the expansion device 14; a first heat exchanger 18 that exchanges heat between a heat medium and the compressed air supplied from the compressor 10 to the tank 12; a second heat exchanger 22 that exchanges heat between the heat medium and the compressed air supplied from the tank 12 to the expansion device 14; a pressure sensor 13 that detects the state of charge (SOC) of the tank 12; SOC adjustment units 17, 34a, 34b, and 34c that adjusts the SOC; and a control device 40. The control device 40 controls the SOC adjustment units 17, 34a, 34b, and 34c such that the detected SOC is within an optimal SOC range while satisfying the requested power. Thus, in this compressed air energy storage power generation device 2 the SOC is controlled so as to be within an optimal SOC range, so the operating efficiency can be improved.

摘要： A heat pump 2 includes an electric motor 6 driven by input electric power, a first compressor 8 mechanically connected to the electric motor 6 and compresses air, a first heat exchanger 14 performing heat exchange between compressed air produced by the first compressor 8 and water, and a first hot water outlet 38 through which the water heated by heat exchange in the first heat exchanger 14 is taken out. Thus, in the air refrigerant heat pump 2, it is possible to use only air and water to supply heating by applying part of compressed air energy storage technology to the heat pump.

摘要： A compressed air energy storage power generation device 2 includes a compressor 6, a pressure accumulator tank 8, and an expander 10. The compressor 6 compresses air by being driven with renewable energy. The pressure accumulator tank 8 stores the air compressed by the compressor 6. The expander 10 is driven by the compressed air. A power generator 36 is mechanically connected to the expander 10 and generates electric power, which is to be supplied to a demander. The compressed air energy storage power generation device 2 includes: first heat exchanges 16 for recovering compression heat; temperature sensors 29a to 29c that measure the temperatures of the heat media having the temperature increased by the first heat exchangers 16; high-temperature heat medium tanks 19 and 20, each of which individually stores the heat medium depending on the temperature thereof; second heat exchangers 22 for heating compressed air; a low-temperature heat medium tank 21 that stores the heat medium having the temperature decreased in the second heat exchanger 22; and a control unit 40 that switches high-temperature heat storage switching valves 31a and 31b to thereby supply the heat medium from the first heat exchangers 16 to either of the high-temperature heat medium tanks 19 and 20. Thus, the compressed air energy storage power generation device 2 can prevent the high-temperature heat medium from mixing with the low-temperature heat medium.

摘要： Energy is stored by injecting fluid into a hydraulic fracture in the earth and producing the fluid back while recovering power and/or desalinating water. The method is particularly adapted to storage of large amounts of energy such as in grid-scale electric energy systems. The hydraulic fracture may be formed and treated with resin so as to limit fluid loss and to increase propagation pressure. The fluid may be water containing a dissolved salt or fresh water and a portion or all of the water may be desalinated using pressure in the water when it is produced.

摘要： 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.
