Pi Green Innovations has commissioned India's first Carbon Capture, Utilization and Sequestration (CCUS) installation based on mineral carbonation, the company announced. The unit operates at the GMR Warora power plant in Maharashtra, marking the entry of mineral carbonation technology into Indian industrial service.

The commissioning, reported by The Tribune, positions the Pune-based emissions-control firm as the first to bring a mineral carbonation CCUS solution to commercial operation in India. The technology captures carbon dioxide from flue gas and reacts it with minerals, converting the CO2 into stable carbonated solids that can be stored or utilized — a chemistry distinct from solvent-based amine capture or geological sequestration routes that dominate CCUS deployments elsewhere.

Mineral carbonation carries a specific appeal for coal-fired power sites such as Warora: the process locks captured carbon into solid mineral form rather than requiring pipeline infrastructure, injection wells, or dedicated geological storage formations, none of which India has yet developed at scale. The approach converts the captured gas into a manufactured product stream, aligning the plant's emissions with utilization rather than pure storage.

The host facility, GMR Warora, is a thermal power station in the Chandrapur district of Maharashtra, one of India's most generation-dense coal corridors. Siting the country's first mineral carbonation CCUS unit at an operating coal plant gives the demonstration a live flue-gas stream and a realistic emissions profile, rather than the synthetic gas streams common to pilot-scale testing.

The commissioning arrives as India's industrial sector faces tightening carbon constraints. The country's Carbon Credit Trading Scheme, under development by the Bureau of Energy Efficiency, will set intensity-based targets for obligated industrial entities, and CCUS installations of this kind could factor into compliance pathways once the mechanism matures. Pi Green has not yet disclosed capture volumes, throughput capacity, or the fate of the carbonated product from the Warora unit.

For Pi Green, a firm better known for air pollution control equipment, the Warora start-up represents a step from particulate filtration into process-level carbon management. First-of-a-kind status in a national market of this size carries commercial weight: India's thermal fleet emits hundreds of millions of tonnes of CO2 annually, and any capture chemistry that works on existing flue gas without major plant retrofit could find a wide addressable market.

What decides what happens next is operating data. The milestone to track is sustained performance at Warora — tonnes of CO2 captured per day, the cost per tonne, and confirmation of a durable utilization route for the carbonated output. Those figures will determine whether India's first mineral carbonation CCUS unit becomes a replicable retrofit template for the country's coal fleet or remains a single-site demonstration.
