Thermal Energy Storage in Packed Bed Using Layered Sensible and Latent Heat Storage
Energy demand continues to increase with a steadily growing global population. Many researchers are working to find new sources of energy while concurrently developing existing technologies. Renewable energy sources such as solar, wind and ocean currents can be used to extract energy. However, these renewable energy sources have inherently low energy densities and are not continuously available as compared to fossil sources. To compete with this, renewable energy sources such as solar energy can be stored in the form of heat when there is a surplus of energy and subsequently used to continue operation when there is a shortage of solar flux or increase in the demand. Systems such as packed beds can be used to store this energy with thermal energy storage (TES). Advancements in energy storage technologies could significantly increase the reliability of renewable energy sources such as solar energy. In these TES packed bed systems, the thermal exergy efficiency is an important component in any application with a goal of high exergetic efficiencies. Exergetic efficiency can be affected by different parameters such as heat losses and axial thermal dispersion, which will be addressed. This proposal aims to improve the efficiency of TES in an air-alumina packed bed system by studying 1) The effect of cyclic behavior to quantify the performance of the TES system for multiple cycles, 2) The thermal behavior using pipe injection techniques to heat the packed bed layers axially and radially, and 3) The effect of multi-layered solid phase change materials (MLSPCMs) on thermal behavior.
