Compressed CO2 may be the answer to affordable long
The good thing about compressed CO2 energy storage systems (CCESS) is that they can be built within the renewable energy parks," Singh said at the India Energy Week in
Among the different ES technologies, compressed air energy storage (CAES) can store tens to hundreds of MW of power capacity for long-term applications and utility-scale. The increasing need for large-scale ES has led to the rising interest and development of CAES projects.
Current long-term energy storage is mainly provided by Pumped-Storage Hydroelectricity (PSH). Compressed Air Energy Storage (CAES) has appeared for decades as a credible alternative but its poor energy efficiency, the need of fossil fuels and the use of existing underground cavities as storage reservoirs have limited its development.
New compressed air energy storage concept improves the profitability of existing simple cycle, combined cycle, wind energy, and landfill gas power plants.

For long-term, we currently has pumped storage systems, but they are location based. The good thing about compressed CO2 energy storage systems (CCESS) is that they can be built within the renewable energy parks," Singh said at the India Energy Week in New Delhi.
Total CAES capacity in India. Total electricity demand in India is estimated at 10 9 MWh annually, therefore the total underground CAES energy storage capacity potential stands at approximately 10 times greater than annual demand if all available land were utilised for this underground storage of air.
Unlike BESS, compressed CO2 energy storage systems do not need critical minerals such as lithium and cobalt. CESS uses only water, steel, and CO2. As per Energy Dome, the cost of the CESS can be as low as $50 per MWh. Discover the latest Business News, Budget 2025 News, Sensex, and Nifty updates.
