NTPC and IIT Bombay Drill Carbon Dioxide Storage Well
In a significant advancement for carbon capture and storage (CCS) technology in India, NTPC Ltd and the Indian Institute of Technology (IIT) Bombay have successfully drilled the country’s first underground carbon dioxide (CO₂) storage evaluation well. This initiative is part of a broader effort to assess the feasibility of long-term CO₂ storage, aimed at reducing greenhouse gas emissions and combating climate change.
Project Overview
The project commenced in November 2022 under the supervision of NITI Aayog, India’s policy think tank. It focuses on evaluating coal seams and sandstone reservoirs for their potential to store CO₂ as part of India’s climate strategy. The initiative is crucial for the country’s goal of achieving net-zero emissions by 2070.
Research Collaboration
This groundbreaking project is a collaborative effort between NTPC’s research arm, NETRA (NTPC Energy Technology Research Alliance), and the Department of Earth Sciences at IIT Bombay. Together, these institutions have developed India’s first geological storage atlas for methane-rich coalfields, which serves as a scientific foundation for future CCS deployment.
Drilling Operations
The drilling operations took place at Pakri Barwadih in Jharkhand, a region known for its coal reserves. The first well was successfully drilled in September 2025, reaching a depth of 1,200 meters. This depth was chosen to study the subsurface geological characteristics that are critical for determining the viability of CO₂ storage. Following the completion of the first well, a second well was drilled on December 21, 2025, further contributing to the geological assessment of the area.
Significance of the Project
The successful drilling of these wells marks a key milestone in India’s indigenous CCS efforts. It paves the way for scalable carbon mitigation strategies in both the power and industrial sectors. The project not only contributes to the understanding of CO₂ storage in India but also aligns with global efforts to reduce carbon emissions and address climate change.
Future Implications
The implications of this project extend beyond immediate geological assessments. By establishing a framework for CO₂ storage, NTPC and IIT Bombay are setting the stage for future research and development in carbon capture technologies. This initiative could lead to the implementation of large-scale CCS projects across India, significantly contributing to the country’s climate goals.
Challenges Ahead
While the successful drilling of the CO₂ storage wells is a promising development, several challenges remain. These include:
- Regulatory Framework: Establishing a clear regulatory framework for CCS projects is essential to ensure safety and environmental protection.
- Public Awareness: Increasing public awareness and acceptance of CCS technologies is crucial for their successful implementation.
- Investment and Funding: Securing adequate funding for research and development in CCS technologies is necessary to advance these initiatives.
Conclusion
The collaboration between NTPC and IIT Bombay in drilling the first CO₂ storage evaluation well represents a significant step forward in India’s efforts to combat climate change. As the country works towards its net-zero emissions target, the insights gained from this project will be invaluable in shaping future carbon capture and storage initiatives. The success of this initiative could serve as a model for similar projects worldwide, highlighting the importance of research partnerships in addressing global environmental challenges.
