A Review of High Temperature Combined Sensible-Latent Heat Storage Systems

In order to wean ourselves from non-renewable energy sources, it is important to increase our focus on renewable forms of energy. One of the most abundant and easily available non-renewable forms of energy is the solar energy. Though solar energy is abundantly available, it availability is intermittent in nature. Energy consumption is not constant. It varies based on the demand. In most of the cases, renewable energy sources do not have the capacity to meet peak load demands. This problem can be solved by storing energy and using it later. Thermal energy storage systems came a long way in fulfilling our ever growing energy demands. Based on the method of storage, the thermal energy storage systems can be broadly classified as sensible heat storage, latent heat storage, and thermo-chemical heat storage. Each method of storage has its own advantages and disadvantages. In order to offset the drawbacks of the individual storage systems and to get maximum efficiency out of a thermal energy storage system, hybrid storage systems comprising two different storage systems are used. The objective of this review is to study the details of combined sensible-latent heat storage systems and highlight their advantages, limitations, applications, heat storage materials and heat transfer fluid (HTF) used, and the potential of these combined systems to offset the limitations posed by individual storage systems. In this study, combined sensible-latent heat storage systems pertaining to high temperature applications are presented. Keywords - energy storage, hybrid storage system, sensible-latent.
