In the spirit of the COP 30 Presidency’s call for a global mutirão – a collective effort to mobilize climate action – the Business Council for Sustainable Energy (BCSE) will lead a business delegation to COP 30 in Belém, Brazil that will bring forward credible solutions, partnerships, investments, and ideas to accelerate the energy transition and decarbonize agriculture, buildings, industry, and transportation. This case study is part of BCSE’s Granary of Solutions to deliver emissions reductions, increase resilience, and meet energy transition goals worldwide.
Highlights:
- New CO2 Battery technology is being deployed in Karnataka, India
- The long duration energy storage technology returns 75% of the energy it absorbs during its charge and lasts for 30+ years
- The project strengthens India’s local supply chain through domestic sourcing and avoids use of rare critical minerals
Case Study:
India’s largest power producer, National Thermal Power Corporation (NTPC), will deploy Energy Dome’s CO2 Battery technology at the Kudgi Super Thermal Power Station in Karnataka.
The CO2 Battery stores energy through adiabatic compression of carbon dioxide gas, which is liquefied when charging the battery and evaporated during discharge in a patented thermomechanical process. Heat created by the compression process is stored and used to expand the CO2 gas, which is driven through a turbine to generate electricity in a closed-loop cycle.
“This is a landmark development in the domain of long duration energy storage (LDES),” said Shri. Gurdeep Singh, Chairman and Managing Director of NTPC. “NTPC is proud to be in the technology forefront and set up the CO2 Battery at NTPC Kudgi. With several advantages viz very long lifetime, no need of critical minerals, [… and] very high depth of discharge, successful demonstration of this technology shall open new vistas in the field of electrical energy storage.”
