Abstract (en)

[origin: WO2010138677A2] In an embodiment of the present disclosure, an energy storage device is presented. The energy storage device includes a porous material that adsorbs air and a compressor. The compressor converts mechanical energy into pressurized air and heat, and the pressurized air is cooled and adsorbed by the porous material. The temperature of the porous material is controlled so that the pressure over it remains essentially constant during the storage and discharge processes. The cooling of the porous material during the storage process, and the heating of the porous material during the discharge process, is assisted by a heat pump which may be either a vapor- compression heat pump, an absorption heat pump, or an adsorption heat pump. The energy storage device also includes a tank used to store the pressurized and adsorbed air and a motor. The motor is driven to recover the energy stored as compressed and adsorbed air by allowing the air to desorb and expand while driving the motor.
