Adani Sanghipuram Carbon Capture Project

On June 22, 2026, Ambuja Cements (part of the Adani Group) and Leilac Limited (a UK-headquartered subsidiary of Australian clean technology company Calix Limited) announced a strategic partnership to develop a commercial-scale carbon capture and hybrid electric heating demonstration project at Ambuja Cements' 6.6 MTPA Sanghi cement plant at Sanghipuram in the Kutch district of Gujarat, India. The project will integrate Leilac's calciner-based direct separation carbon capture technology, which isolates the process CO₂ released during limestone calcination from combustion flue gases, together with a hybrid electric heating system that allows the calciner to be heated by renewable electricity. The initial scope is a commercial demonstration at the Sanghi plant; subject to successful demonstration, the parties have stated the project could be scaled up 7x to 8x to capture more than 1 million tonnes of CO₂ per year, which would position it as one of the world's largest industrial-scale low-carbon cement projects. Project capex, schedule, the downstream pathway for captured CO₂ (storage or utilization), and offtake structure have not yet been publicly disclosed.
