Sensible heat thermal energy storage (SHTES) has been proven to reduce CSP capital costs, and as a result, several new installations have implemented SHTES. The disadvantages of SHTES include the large quantities of salt medium required to store the thermal energy, the two correspondingly large storage tanks, as well as the risk of solidification of the salt if the temperature within the storage tanks drops below the salt's freezing point (Mills, 2004). Latent heat thermal energy storage (LHTES) is of particular interest because it stores thermal energy through solid-liquid phase changes and, when compounds with a high heat of fusion are used, it requires less storage medium relative to SHTES, reducing capital and construction costs.
