Abstract: A compressed air energy storage module including an integrated thermal energy storage and recovery apparatus is provided. The compressed air energy storage module contains no moving parts and is constructed onsite, underground and out-of-sight. The compressed air energy storage module comprises a first regenerative heat exchanger including a first tank filled with a first particulate material that stores thermal energy and adsorbs air, and a second regenerative heat exchanger including a second tank filled with a second particulate material that stores thermal energy. A first end of the first tank is connected to a first end of the second tank via a first piping system. A second end of the first tank is connected to a second end of the second tank via a second piping system. The first piping system and the second piping system form a circular path for the air to circulate through the first and second regenerative heat exchangers.

Abstract: 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 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.
