NTPC Ltd. Will collaborate with Triveni turbine and the Italian energy dome to install a 160 MWH CO2 battery in the Kudgi Super Thermal Power Station in India.
NTPC LTD, the largest integrated power generation company in India, has launched a CO2 battery energy storage project in his Kudgi Super Thermal Power Station in Bijapur District, Karnataka.
Netra, the R&D division of NTPC, will supervise the project in collaboration with Triveni Turbine and Italian CO2 battery technology company Energy Dome.
NTPC Kudgi will host a CO2 battery with a 160 MWh of energy storage capacity. The project will support the NTPC strategy to take over long-term energy storage (LDES) technologies for cost-effective, 24-hour green power as it expands its capacity of renewable energy.
The CO2 battery technology from Energy Dome does not use lithium or rare-earth elements. Instead, it relies on directly available components of established supply chains, in accordance with the ‘Make in India’ of the Indian government and ‘Atmanirbhar Bharat’ initiatives.
In contrast to electrochemical storage systems for batteries, the CO2 battery works on specialized electromechanical turbo machines. It follows a “closed brayton -thermodynamic cycle”, with anhydrous CO2 as process fluid. The system stores and gives up electricity by shifting CO2 between vapor and liquid situations.
“With various advantages, including a very long service life (> 25 years), no need for critical minerals such as lithium and cobalt, topography agnostic, minimal performancegradation in contrast to bess where complicated electrochemistry is involved, and a very high depth of discharge (100 %), Successful demonstration of this technology will open new vistas in the field of storage of electrical energy, ”said Gurdeep Singh, chairman and director of NTPC.
CEO of Energy Dome, CEO Claudacini, said that the CO2 battery will further promote the Doxbonization objectives of NTPC and the 24-hour (RTC) power episode, while the local supply chain of India is reinforced by domestic purchasing.
