Energy Storage System—Applications and Case Study

This paper presents the application and business case study of Compressed air energy storage (CAES) system. To achieve low carbon emission, India is moving towards renewable energy sources and constantly reducing the carbon footprints. Transport ministry is also intending for India to move towards 100% electric cars by 2030. As per energy generation report, in year 2009–10 the power generation of India was short by 10% of the required power and by year 2018–19, this figure has dropped to 0.6%. India is targeting for installation of 175GW of Solar, wind and hybrid power plants by year 2022. It’s expected that in the coming years, India will be generating surplus power. In such scenario, a technology to store the energy can play a major role for Indian grid. Energy storage system can provide flexibility needed to better integrate the unreliable power generated by various energy sources and meet the flexible power demand. Technology in storage system is continuously upgrading and various modes of energy storage systems have developed in the recent time. Many pilot energy storage projects are successfully executed in the world. Asia is being considered as the hub for investment in energy storage market. In this paper, application, case studies and environmental impacts of CAES technologies shall be covered.
