MODELLING AND ANALYSIS OF SAND BATTERY SYSTEM

Abstract

Energy is a basic necessity shared by all living things on the planet, much like water, food, and shelter. The main source of producing usable kinds of energy is fossil fuels. In light of this, the main cause of ozone depletion and global-warming are the fossil fuels. The search for energy sources that are independent of fossil fuels and have a smaller impact on global warming has been reignited by the recent rise in awareness of it. Renewable-Energy Sources (RES) like wind and solar and hydropower are more accessible when compared to fossil fuel alternatives. It is appropriate to use thermal energy from the sun for both heating purpose and cooling purpose. Low temperature heating processes like household heating of water, household and industrial heating of areas and spaces, heating of swimming pool, ventilation operations, and some manufacturing processes and industrial processes are among the main applications for solar technologies. This research aims to investigate the possibility of using Indian desert sand as a material for energy storage in a high-temperature TESs. Sand has the potential to be a novel and environmentally friendly storage medium with low maintenance and operating costs. The Thermal Energy Storage Element will store thermally charged sand. It will need to be stored for a particular amount of time after achieving the right temperature in the sand to assess its efficiency. The remaining heat will then be released and absorbed by the oil, and it will employ a Peltier Element to produce electricity. The experiments are divided into three sections : Charging Phase, Storing Phase, and Discharging Phase, but the simulation has been performed only for the charging part. Certain design constraints are addressed, as well as several methods for improving system functionality for future optimization.
