  • HEAT TRANSFER FLUIDS COMPOSITIONS
    Publication number: 20190161665
    Abstract: There is provided heat transfer fluids comprising at least one organic fluid, such as an oil and at least one phase change material such as a molten salt that exhibit advantageous heat storage capacities and viscosity properties for heat transfer in such systems as compressed air energy storage systems.
    Type: Application
    Filed: October 22, 2018
    Publication date: May 30, 2019
    Inventor: Abdelfettah BANNARI
  • COMPRESSED AIR ENERGY STORAGE AND RECOVERY
    Publication number: 20190003384
    Abstract: A compressed air system energy storage and recovery system has a compressed air tank structured to store compressed air above 200 bars, a heat storage unit containing a heat transfer fluid and having a latent heat storage material, and a heat exchanger. The heat exchanger extracts heat from compressed ambient air above 200 bars for storage and to heat compressed air from the tank above 200 bars prior to expansion and use to recover energy in the air motor. Efficiency of energy storage and heat exchange is improved using pressures above 200 bars.
