Ambuja Cements, part of the Adani Group, has partnered with UK-based clean tech firm Leilac to build one of the world's largest commercial-scale low-carbon cement production facilities at Sanghipuram in Kutch, Gujarat. The project aims to integrate Leilac's carbon capture and hybrid electric heating technology to reduce process emissions and eventually eliminate coal use. If successful, the plant could be scaled up to capture over one million tonnes of CO2 annually. The initiative supports Ambuja Cements' SBTi-validated net zero target for 2050. The company is also expanding its captive renewable energy capacity to nearly 1 GW to power the electrification of cement manufacturing. This collaboration could improve the economics of carbon capture and provide a replicable model for the global cement industry, which accounts for roughly 8% of global CO2 emissions.

Cement is a hard sector to decarbonize because most emissions come from the chemical process, not just fuel. If Leilac's tech can really cut coal to zero and capture process CO2 at scale, this could be a big deal for India's industrial emissions.

The 1 million tonne CO2 capture target is ambitious. But the article doesn't mention capture cost per tonne or what happens to the captured CO2. Utilization pathways matter for the economics.

They mention nearly 1 GW of captive green power. That's a lot of solar or wind. Would be curious to know if they have firm storage to back up the electric heating, or if they plan to run the capture intermittently.

SBTi validation is good, but net zero by 2050 is still 24 years away. The real test is whether this demo plant actually gets built and scaled within 5 to 7 years. Policy support like carbon credits or tax breaks will decide if it's replicable.

If they can really eliminate coal in cement production, that's a massive shift for India's industrial energy use. But hybrid electric heating at scale is unproven. Hope they share real performance data once operational.
