Due to increased population, lot of emissions and pollutions are taking places in power sector, telecommunication sector, automobile sector etc. Hence there is need to reduce Green-house emission and other pollutions in various sectors by reducing/removing our dependency on fossil fuels. Renewable energy sources is gaining lot of attraction in power sector. The power networks faces lot of challenges in transmission and distribution to meet daily demands. In order to meet these challenges energy storage system plays very important role. Energy storage system is playing very important role in automobile industry & telecommunications green technology also to reduce pollution and green-house effect. Lead acid battery is most widely used in India due to its well-known chemistry, infrastructure low price and efficiency. The real disadvantage in lead acid battery is that it easily sulfates because of improper charging and discharging. This sulfation is more dominant in stationary applications. This paper basically focuses on various types of energy storage systems, their viability for particular applications, cost and life. Paper also focuses on the various techniques used to reduce sulfation in lead acid battery application and improving its life by reducing sulfation by artificial intelligence. © 2016 IEEE.
