    摘要: A system and method for thermoelectric energy storage is described. A thermoelectric energy storage system (22, 36) having a heat exchanger (30) which contains a thermal storage medium, and a working fluid circuit for circulating a working fluid through the heat exchanger (30) for heat transfer with the thermal storage medium. The working fluid undergoes transcritical cooling during the charging and transcritical heating during the discharging cycle as it exchanges heat with the thermal storage medium. Improved roundtrip efficiency is achieved through minimising the maximum temperature difference (”Tmax) between the working fluid and the thermal storage medium during operating cycles.

    摘要: An energy storage apparatus includes a first circuit containing a first phase change material, second circuit containing a second phase change material, and a heat pump having a cold side heat exchanger thermally coupled to the first circuit and a hot side heat exchanger thermally coupled to the second circuit. The apparatus is operable in a charging mode, a storage mode, and a discharge mode. In the charging mode the heat pump is energized to cool the first phase change material and heat the second phase change material. In the storage mode the first phase change material is stored in a first storage vessel and the second phase change material is stored as a pressurized vapor in a second storage vessel. In the discharge mode vaporized first phase change material is expanded by a first expander, or the vaporized second phase change material is expanded by a second expander.

    摘要: In an energy storage and recovery system,working fluid from a first vessel is compressed by power machinery and passes, via a regenerator, into a second vessel, where it is forced to condense, the temperature and pressure of the saturated working liquid/vapour mixture continuously rising during storage. The stored energy is recovered by the vapour returning through the regenerator and power machinery where it expands to produce work before condensing back into the first vessel. The regenerator comprises a gas permeable, solid thermal storage medium which, during storage, stores superheat and some latent heat from the vapour passing through it in respective downstream regions that exhibit continuously increasing temperature profiles during storage and a small temperature difference with the surrounding vapour, thereby minimising irreversible losses during the thermal energy transfers.

    摘要: A system and method for thermoelectric energy storage is described. The system has a charging cycle (10) for providing thermal energy to a hot thermal storage arrangement (18, 20, 22) and an evaporative ice storage arrangement (24) and a discharging cycle (30) for generating electricity by retrieving the thermal energy. The evaporative ice storage arrangement (24) comprises a heat exchanger (14, 36), an ice slurry storage tank (26), a vacuum evaporation chamber (28) and a slurry heat exchanger (40). The evaporative ice storage arrangement (24) of the present invention functions as a dedicated cold storage for the thermoelectric energy storage system. The cold storage is realized by producing an ice-water mixture during charging of the storage, and using the stored ice-water mixture to condense the working fluid during the discharge cycle (30). Use of this sub-triple-point evaporation arrangement functions to increase the round-trip efficiency of the TEES system through minimising the maximum temperature difference between the working fluid and the thermal storage medium during operating cycles.
