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 intends to provide a continuous supply of heat over day and night for power generation, to rectify solar irradiance fluctuations in order to meet demand requirements by storing energy as heat.
Thermal energy storage (TES) can be a potential alternative to address the intermittency of solar energy by storing heat during sunshine duration and releasing during the offsun periods. Hence, TES can not only improve the dispatchability of solar energy but also can increase the reliability and effectiveness of CST systems.
Thermal energy storage for CSP plants. Sensible heat storage: defined as storage that exploits the physical properties of a material to store thermal energy at the expense of a temperature rise of the material itself, due to the temperature variation fluid used.
It also includes a summary on the importance of materials requirements at different plants subsystems as receiver, Brayton cycles power units (including sCO 2 cycles) and heat exchangers. Thermal energy storage systems are usually divided into 3 subgroups: sensible heat, latent heat and thermochemical storage.
As a result, TES has been identified as a key enabling technology to increase the current level of solar energy utilization, thus allowing CSP to become highly dispatchable. Thermal energy storage systems for CSP plants have been investigated since the start of XXI century , .
