Aim is to develop & deploy innovative CCU Test bed in Cement Sector with thrust on Developing CO2 capture + CO2 Utilization integrated unit in an Industrial set up through Public Private Partnership (PPP) funding model.
- Ministry: Department of Science and Technology (DST) under Ministry of Science & Technology.
- The testbeds will showcase innovative processes like-
- Oxygen-enhanced calcination: CO₂ to concrete blocks & olefins (e.g., ethylene, propylene).
- Carbon-negative mineralization: Locks CO₂ into rock.
- Vacuum Swing Adsorption: Separate CO₂ from cement kiln gases and integrate it back into construction materials.
About Carbon Capture and Utilisation (CCU)
- Definition: CCU is a set of technologies that allow for the capture & use of carbon as a feedstock for making essential products such as fuels, chemicals, etc, which are predominantly derived from fossil resources.
- Carbon Capture:
- From industrial (e.g., cement plants) or energy (e.g., biomass power plants) sources: Technologies like membranes, solvent absorption, or adsorption separate CO₂ from flue gases.
- Directly from the air (Direct Air Capture - DAC): Ambient air is drawn through a gas trapping system where CO2 is isolated from the rest of the air and then released to be used or stored.
- Carbon Utilisation: Once captured, CO₂ can be utilised through two main pathways:
- Direct Utilisation & CO₂-to-Products (See image)
