Work Detail |
The project will be executed on a turnkey basis at NTPCs Kudgi plant in Karnataka, India. India’s NTPC (previously the National Thermal Power Corporation) has launched its first 160 megawatt hours (MWh) CO2 battery energy storage project, to be developed by Triveni Turbine and its energy partner Energy Dome. The project will be executed on a turnkey basis at NTPC’s Kudgi plant in Karnataka, India. The initiative aligns with NTPC’s strategy to diversify its energy portfolio and increase renewable power generation. The adoption of CO2 battery technology also supports India’s “Make in India” and “Atmanirbhar” (self-sufficiency) policies, offering opportunities for the domestic industrial supply chain and potential global exports. Energy Dome founder and CEO Claudio Spadacini stated: “The best projects are those that create win-win opportunities. Our collaboration with Triveni Turbines and NTPC to deploy the CO2 battery achieves this by advancing NTPC’s decarbonisation goals and round-the-clock power delivery while strengthening India’s local supply chain through domestic sourcing. “This project not only demonstrates the potential of sustainable innovation but also establishes a key global reference for our transformative technology, contributing to a cleaner and more resilient energy future.” Energy Dome’s technology employs a closed thermodynamic cycle that charges by drawing carbon dioxide from a dome gasholder. The carbon dioxide is stored under pressure and dispatched by evaporating. The gas then expands through a turbine generating electricity before returning to the gasholder. NTPC chairman and managing director Gurdeep Singh stated: “This is a landmark development in the domain of long-duration energy storage. NTPC is proud to be in the technology forefront and set up the CO2 battery at NTPC Kudgi”. He went on to say that “with several advantages viz very long lifetime (more than 25 years), no need of critical minerals viz lithium, cobalt, topography agnostic, minimal performance degradation – unlike BESS [battery energy storage systems] where intricate electrochemistry is involved, very high depth of discharge (100%) – successful demonstration of this technology shall open new vistas in the field of electrical energy storage.” |
