“A Review on the Thermal Energy Storage Unit for Solar Energy Application”

Abstract

With the current high energy demand, relying solely on fossil fuels would undoubtedly lead to crises in the future, particularly for emerging nations. Even while the use of renewable energy sources, such as solar energy, is widespread these days, the issue lies in the economy and law, or social and acceptance. The primary causes of these kinds of problems are the low density of solar radiation on Earth's surface and, when present, its erratic nature according to the season and time of day. Solar energy storage units must be implemented in solar thermal energy applications in order to overcome these kinds of challenges. Unlike other solar energy conversion technologies, solar thermal energy (STE) gives the possibility of storing excess energy produced for later use. This is an assured way to extend operating hours and, consequently, power production capacity.
