IIT Madras pilots geothermal power project using abandoned oil and gas wells
On April 25, 2026, the Indian Institute of Technology (IIT) Madras announced an innovative project aimed at generating electricity from abandoned oil and gas wells through geothermal energy. This groundbreaking initiative is set to take place at an Oil and Natural Gas Corporation (ONGC) site located in Ankleshwar, near Surat, Gujarat.
Project Overview
The geothermal power project is funded by the Ministry of New and Renewable Energy with an investment of ₹15.5 crore. The primary objective of this pilot project is to produce up to 450 kilowatts (kW) of continuous power over a span of two years. This initiative is expected to contribute significantly to the renewable energy landscape in India.
Leadership and Coordination
The project is spearheaded by Rajesh Nair, who serves as the Faculty Coordinator for the IIT Madras Green Hydrogen and Hydrocarbons Tech Consortium, within the Department of Ocean Engineering. Under his leadership, the project aims to explore the potential of utilizing existing infrastructure to harness geothermal energy efficiently.
Geothermal Energy: A Sustainable Solution
Geothermal energy is derived from the heat stored beneath the Earth’s surface. It is a sustainable and eco-friendly source of energy that can be harnessed for electricity generation and direct heating applications. The use of abandoned oil and gas wells for geothermal energy production presents a dual benefit: it repurposes existing infrastructure while reducing the environmental impact associated with drilling new wells.
Benefits of Geothermal Energy
- Renewable Resource: Geothermal energy is a renewable resource that can provide a continuous supply of energy, unlike fossil fuels.
- Low Emissions: It produces minimal greenhouse gas emissions compared to traditional energy sources, contributing to climate change mitigation.
- Base Load Power: Geothermal power plants can provide a stable and reliable source of electricity, making them ideal for base load power generation.
- Reduced Land Footprint: Utilizing existing wells minimizes the need for new land development and reduces habitat disruption.
Implementation Strategy
The implementation of this geothermal project involves several key steps:
- Site Assessment: Conducting a thorough assessment of the abandoned oil and gas wells to determine their suitability for geothermal energy extraction.
- Technology Selection: Identifying and selecting appropriate technologies for harnessing geothermal energy effectively.
- Infrastructure Development: Developing the necessary infrastructure to support the geothermal power generation process.
- Monitoring and Evaluation: Establishing a robust monitoring system to evaluate the performance and efficiency of the geothermal power plant.
Challenges and Considerations
While the project holds great promise, several challenges must be addressed to ensure its success:
- Technical Challenges: Adapting existing oil and gas wells for geothermal energy extraction may require innovative engineering solutions.
- Regulatory Hurdles: Navigating regulatory frameworks and obtaining necessary approvals can be time-consuming and complex.
- Financial Viability: Ensuring the financial sustainability of the project through effective cost management and securing additional funding may be necessary.
Future Prospects
The successful implementation of this geothermal power project could pave the way for similar initiatives across India and beyond. By demonstrating the viability of using abandoned wells for renewable energy production, IIT Madras is setting a precedent for sustainable energy practices.
Furthermore, this project aligns with India’s broader goals of increasing the share of renewable energy in its energy mix and reducing dependence on fossil fuels. As the world grapples with climate change and the need for sustainable energy solutions, initiatives like this offer a glimpse into a cleaner and more sustainable future.
Conclusion
The geothermal power project at IIT Madras represents a significant step towards innovative energy solutions that leverage existing resources. By utilizing abandoned oil and gas wells, this initiative not only aims to generate renewable energy but also addresses environmental concerns associated with fossil fuel extraction. As the project progresses, it will be crucial to monitor its outcomes and share insights that could benefit similar efforts globally.
