  • THERMAL ENERGY STORAGE DEVICE AND SYSTEM
    Publication number: 20230341192
    Abstract: A thermal energy storage device may include a heat storage medium, one or more thermosyphons, a discharging plenum chamber, and a discharging plenum chamber. The one or more thermosyphons may include an evaporative section configured to charge the thermal energy storage device, a condensing section configured to discharge the thermal energy storage device, and a heat transfer section extending between the evaporative section and the condensing section and fluidically coupled to the evaporative section and the condensing section. At least a portion of the heat transfer section may be disposed in the solid heat storage medium. At least a portion of the evaporative section and the condensing section may be disposed outside the solid heat storage medium.

  • ENCAPSULATED PHASE CHANGE APPARATUS FOR THERMAL ENERGY STORAGE
    Publication number: 20110259544
    Abstract: Provided are apparatus and methods for storing thermal energy. For example, an apparatus including comprising at least one phase change material, and a capsule containing the at least one phase change material. The capsule may be permanently or temporarily sealed to contain the encapsulation material. The encapsulation material includes at least one material that is chemically and physically distinct from the phase change material. The encapsulation material and phase change material are selected to store and discharge thermal energy at temperatures of greater than 400° C. without capsule failure.
