Solar Thermal Energy Storage Technology: Current Trends

Energy security has major three measures: physical accessibility, economic affordability and environmental acceptability. For regions with an abundance of solar energy, solar thermal energy storage technology offers tremendous potential for ensuring energy security, minimizing carbon footprints, and reaching sustainable development goals. Global energy demand soared because of the economy’s recovery from the COVID-19 pandemic. By mitigating the adverse effects of solar energy uncertainties, solar thermal energy storage provides an opportunity to make the power plants economically competitive and reliable during operation. Solar thermal power plant technology is still in the early stages of market introduction, with about six gigawatts of installed capacity globally in 2020 compared to PV technology. In a developing economy, the potential for cost reduction through invention, mass production, and growing competitiveness is far from being exhausted. The objective of this review paper is to access the progress of solar thermal energy technology in India compared to world and its potential to accomplish the clean energy goals.
