The government has selected Tamil Nadu as one of five sites in India to host a pioneering carbon capture and utilisation (CCU) testbed, aiming to significantly reduce CO₂ emissions in the cement industry. This sector currently contributes nearly 7–8% of India’s industrial carbon footprint. The initiative supports India’s broader 2070 net-zero target and highlights the government’s commitment to clean energy innovation.
Ultratech Reddipalayam Plant at the Core
The CCU testbed will be set up at Ultratech Cement’s Reddipalayam plant in Ariyalur district. The project receives technical backing from IIT Madras and BITS Pilani, Goa campus. Part of a national programme led by the Department of Science and Technology (DST), the effort seeks to validate breakthrough CCU technologies that can transform captured CO₂ into value-added products such as synthetic fuels, urea, soda ash, food-grade CO₂, and concrete aggregates.
Testing Advanced Oxygen-Enriched Combustion
At Reddipalayam, researchers will trial an oxygen-enriched combustion system capable of capturing up to two tons of CO₂ per day. They will then mineralise the captured carbon using concrete blocks, fines, and sludge, demonstrating scalable pathways to reuse emissions within industrial processes.
Collaborative Effort Across India
The Tamil Nadu facility is part of a wider initiative that includes CCU testbeds in Chittorgarh (Rajasthan), Sundergarh and Rajganjpur (Odisha), and Kurnool (Andhra Pradesh). Each site is developing distinct CCU technologies in collaboration with leading academic institutions and industry partners. Together, they are creating a network of innovation aimed at decarbonising heavy industries.
Paving the Way for a Low-Carbon Future
By integrating research, industry expertise, and policy support, the CCU programme demonstrates how carbon capture can move from concept to commercial reality. As reported by projectstoday.com, Tamil Nadu is leading the effort to host this testbed. This positions the state at the forefront of India’s carbon reduction strategy. This move brings the country closer to its climate goals while unlocking new avenues for sustainable industrial growth.
