Thermal energy storage – overview and specific insight into
Characterization of thermal energy storage in molten salts requires data of salt properties in the liquid phase. For sensible storage media the storage capacity is directly proportional to the heat capacity which therefore is an essential parameter. Several data exist which are summarized in the following.
Performance improvement of liquid air energy storage:
Liquid air energy storage (LAES) is a promising energy storage system with the main advantage of being geographically unconstrained. The efficiency of LAES could be improved by utilizing compression heat and integration with other systems. As an effective heat recovery process, the Stirling engine (SE) is introduced to the LAES system.

The fluid currently used for energy storage in the concentration solar power plants is the binary mixture 60% NaNO 3 + 40% KNO 3, called solar salt. The use of this mixture has made possible the building of commercial plants that reach until 15 hours of energy storage (SENER and Torresol Energy, 2014). This mixture was chosen because it is
Energy Storage
Compressed air energy storage works similarly, but by pressurizing air instead of water. Another technology being developed is called thermal energy storage, which stores energy as heat in an inexpensive medium such as rocks, liquid salt or cheap elements. Each form of energy storage has its own challenges and advantages.
