In various embodiments, efficiency of energy storage and recovery systems employing compressed air and liquid heat exchange is improved via control of the system operation and/or the properties of the heat-exchange liquid.
1. A method for improving efficiency of a compressed-gas energy storage and recovery system, the method comprising: within a cylinder assembly, compressing gas from a first pressure to a second pressure larger than the first pressure, thereby storing energy;during the compression, introducing a heat-transfer fluid into the cylinder assembly to exchange heat with the gas, thereby increasing efficiency of the energy storage, a portion of the gas dissolving into the heat-transfer fluid;exhausting from the cylinder assembly gas at the second pressure, at lea...
