Thermal Energy Storage (TES) has been a key technology in energy systems for conserving energy and increasing energy efficiency by addressing the discrepancy between energy supply and demand. TES involves storage of high- or low-temperature thermal energy in the form of sensible heat, latent heat, or through thermochemical reactions or processes.
An overview of major strategies for thermal energy storage is shown in Fig. 1. Sensible heat storage is based on storing thermal energy by heating or cooling a liquid or solid medium (e.g. water, sand, molten salts, rocks), with water being the most widely used because of its relatively high heat capacity, low cost, and being benign .
Solid-liquid PCMs commonly used for thermal energy storage include organic PCMs (paraffins) and Inorganic PCMs (salt hydrates), or various mixtures thereof (eutectics). Various strategies are often used to enhance the performance of SL-PCMs for thermal storage applications by addressing their inherent drawbacks.
Solid-solid phase change materials (SS-PCMs) for thermal energy storage have received increasing interest because of their high energy-storage density and inherent advantages over solid-liquid counterparts (e.g., leakage free, no need for encapsulation, less phase segregation and smaller volume variation).
Therefore, one key factor for thermal energy to play a role in electricity storage is to improve thermal-cycle efficiency, which is possible by adopting a high-efficiency ABCC power system that is adapted from a conventional GTCC.
A novel standalone particle TES system is evaluated for electric energy storage. The system stores low-price, off-peak electricity as thermal energy for later dispatch to produce high-value, peak-demand electricity. The TES system uses particle-storage media at 1200°C to drive a high-efficiency combined cycle to obtain a high roundtrip efficiency.
