Assessment of Role of Energy Storage Technologies for Renewable Energy Deployment in India
This technical assessment report outlines India’s clean energy future, and the challenges that the system will face from constrained transmission and distribution capacity, unmet energy demand, low energy access in rural areas, and a continuing dependence on coal-based generation. The report argues that the increase of renewable energy (RE) sources, abundant in India, will help solve these challenges. RE development, supported by the government of India, will depend somewhat on the future of RE storage — ranked one of the 12 most important technologies of the future by consulting firm McKinsey.
In India, storage is a component of the country’s energy strategy, which also includes Smart Grid and Electric Vehicle initiatives. According to the report, storage provides benefits including time shifting, grid stabilization, shaving of peak demand, improved generation efficiency, and improved utilization of transmission capacity.
The report presents energy storage technologies, analysis of their costs, performance, and maturity levels. It concludes that storage systems including lithium-ion batteries, ultra batteries, reversible hydrogen fuel cells, and underground thermal, are of particular interest to India
Excerpt from the report:
The analysis shows that storage technologies that can be implemented at cost levels of less than USD 500 per kW and less than USD 0.10 per kWh/discharge cycle (electrical storage) have a huge potential for application in India.
The key areas where storage applications can play a key role to enhance RE deployment:
- Grid integration of RE projects (solar, wind)
- Rural micro-grids
- Energy management systems for large users, integrating onsite RE projects (residential, commercial, industrial complexes)
