Review - Optimization and Property Enhancement Methods of Sand based Energy Storage

Increasing environmental concern around the world makes researchers to work for the development of cost effective storage systems for storing excess or waste energy available in industry and nature. Most of the commercialized electrochemical storage systems are using harmful chemical compounds, which are creating hazard to environment and mankind during their disposal. Moreover, those systems are economically expensive and having limited operation time. Hence, it is necessary to develop energy storage system operates on eco-friendly and cost effective storage material. In this review article, usage of sand in energy sector has been analyzed from its properties, applications, limitations, performance enhancement methods and scope of future research.
