摘要： An electrothermal energy storage and discharge system is provided including a charging cycle and a discharging cycle. The charging cycle includes a refrigeration unit and a thermal unit, and the discharging cycle includes a power unit. The refrigeration unit is driven by an excess electric power and is configured to generate a cold energy storage having a solid carbon dioxide. The thermal unit is driven by a thermal energy and is configured to generate a hot energy storage and/or provide a hot source. The power unit operates between the cold energy storage and at least one of the hot energy storage and hot source so as to retrieve the energy by producing a high pressure carbon dioxide and a hot supercritical carbon dioxide, and generating an electric energy using the hot supercritical carbon dioxide.

摘要： A regenerative closed loop thermodynamic power generation cycle system is presented. The system includes a high-pressure expander to deliver an exhaust stream. A conduit is fluidly coupled to the high-pressure expander, which is configured to split the exhaust stream from the high-pressure expander into a first exhaust stream and a second exhaust stream. The system further includes a first low-pressure expander and a second low-pressure expander. The first low-pressure expander is coupled to a pressurization device through a turbocompressor shaft, and fluidly coupled to receive the first exhaust stream. The second low-pressure expander is coupled to the high-pressure expander and an electrical generator through a turbogenerator shaft, and fluidly coupled to receive the second exhaust stream. A method for operating the regenerative closed loop thermodynamic power generation cycle system is also presented.

摘要： A power plant may include a magnetohydrodynamic (MHD) generator having an MHD exhaust that is cooled using a compressor exit flow to a temperature at which the MHD exhaust can be fed to at least one stage of a gas turbine. The heated compressor exit flow may be used to feed a combustor for the MHD generator. In an alternative embodiment, the gas turbine exhaust may be used in a heat recovery steam generator for a steam turbine system, and then fed back to a compressor for the combustor to the MHD generator. In another embodiment, a power plant may include a compressor exit flow feeding a combustor for an MHD generator and an MHD exhaust may be mixed with a compressor pre-exit, extraction flow for feeding to at least one stage of a gas turbine.

摘要： A method for operating a closed loop regenerative thermodynamic power generation cycle system is presented. The method includes supplying a high-temperature working fluid stream at a first pressure P1 to an expander, and extracting a partially expanded high temperature working fluid stream from the expander at a second pressure P2. Each of the first pressure P1 and the second pressure P2, are higher than a critical pressure of the working fluid; and the second pressure P2 is lower than P1. The method further includes regeneratively supplying the extracted high temperature working fluid stream at the second pressure P2 to a low temperature working fluid stream at the first pressure P1. A closed loop regenerative thermodynamic power generation cycle system is also presented.
