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.

A system and method for providing dry cooling of a coolant in a directed energy system, having a plurality of heat exchangers which depolymerize and polymerize a polymer. Specifically, the depolymerization process is endothermic and draws heat from a source liquid in a first heat exchanger, and the polymerization process is exothermic and expels heat from a second heat exchanger. Additional heat exchangers and holding tanks may be incorporated in the system and method. Pumps having adjustable volumetric flow may be incorporated and provide customized cooling and energy draw.

This application provides an integrated power generation system with thermal energy and pressure storage cycles comprising a heat and pressure storage unit connected to a heat source, the heat source absorbs and transmits thermal energy to the unit to heat and pressurize a first working substance and convert it to a gaseous state; a first power generation device receives the high-temperature and high-pressure first working substance released from the unit and converts the fluid kinetic energy of the first working substance into electrical energy; a heat storage tank receives the first working substance flowing through the first power generation device for heat exchange and storage of thermal energy; and a cooling tank receives the first working substance from the heat storage tank to enable the first working substance and undergoes a phase change into a liquid state and then transmits it to the unit to complete a cycle.

Cryogenic energy storage systems, and particularly methods for capturing cold energy and re-using that captured cold energy, are disclosed. The systems allow cold thermal energy from the power recovery process of a cryogenic energy storage system to be captured effectively, to be stored, and to be effectively utilised. The captured cold energy could be reused in any co-located process, for example to enhance the efficiency of production of the cryogen, to enhance the efficiency of production of liquid natural gas, and/or to provide refrigeration. The systems are such that the cold energy can be stored at very low pressures, cold energy can be recovered from various components of the system, and/or cold energy can be stored in more than one thermal store.
