About ONGC Carbon Capture Pilot projects
- ONGC is currently spearheading its first full-scale Carbon Capture and Storage (CCS) pilot project at the Gandhar oilfield in Gujarat.
- This innovative project involves:
- The project involves capturing CO₂ from nearby industries in Dahej and ONGC’s Hazira plant.
- The captured CO₂ will be transported to Gandhar and injected underground through two abandoned onshore wells at about 100 tonnes per day.
- Aim: The project also aims to test using CO2 to enhance oil recovery ( EOR), turning a potentially harmful greenhouse gas into a productive resource, they said.
