What does Carbon Clean do?

Carbon Clean, founded in 2009 by CEO Aniruddha Sharma, develops point-source carbon capture solutions for hard-to-abate industries including steel, cement, and oil and gas. Its flagship product is the CycloneCC C1 series, a columnless modular unit designed to capture up to 100,000 tonnes of CO₂ per year while reducing the physical footprint and capital cost associated with conventional carbon capture plant.
