Thermal storage plays a crucial role in solar systems as it bridges the gap between resource availability and energy demand, thereby enhancing the economic viability of the system and ensuring energy continuity during periods of usage.
Thermal energy storage provides a workable solution to the reduced or curtailed production when sun sets or is blocked by clouds (as in PV systems). The solar energy can be stored for hours or even days and the heat exchanged before being used to generate electricity .
A seasonal solar thermal storage system stores energy during the hot summer months and uses it during colder winter weather. Solar thermal energy is captured by solar collectors and stored in different ways.
Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes.
Solar thermal storage (STS) refers to the accumulation of energy collected by a given solar field for its later use.
The efficiency of a solar thermal system can be enhanced by coupling the storage tanks of solar thermal energy and PCM based latent heat storage technology. High efficiency can also be achieved by bridging the gap between demand of hot water and availability of solar radiations.
A comparative assessment of various thermal energy storage methods is also presented. Sensible heat storage involves storing thermal energy within the storage medium by increasing temperature without undergoing any phase transformation, whereas latent heat storage involves storing thermal energy within the material during the transition phase.
