ENERGY TRANSFER USING HIGH-PRESSURE VESSEL

Disclosed techniques include energy transfer using high-pressure vessels. Liquid is pumped into a high-pressure vessel to pressurize a gas. The gas can include air. Liquid is sprayed into the high-pressure vessel to cool the gas. Heat exchange is performed to cool the liquid before spraying the liquid into the high-pressure vessel. The spraying liquid into the top and the bottom of the high-pressure vessel is accomplished using nozzles in a top portion and nozzles in a bottom portion of the high-pressure vessel. The pressurized gas is transferred into a storage reservoir. The storage reservoir can include an underground cavern or aquifer. Gas from the storage reservoir is delivered to drive a turbine to recover stored energy. The extracting gas from the storage reservoir is accomplished using an additional high-pressure vessel. Heat exchange is performed to warm the liquid before spraying the liquid into the additional high-pressure vessel.
