A liquid energy storage system where the thermodynamic relationship for lost work is characterized by: Wlost=TOIntegral(T1−T2)/(T1×T2)dH, where To is the ambient temperature and T1, and T2 are the temperatures of the hot and cold streams, respectively, all temperatures are absolute temperatures, and H represents the enthalpy or heat content of the fluids in the heat exchange process.
