Exploring thoroughly: India’s geothermal policy must be approached with caution

India possesses a considerable geothermal resource, yet its contribution to the overall energy mix is minimal

Introduction: India’s ambitious drive towards renewable energy sources has increasingly brought geothermal power into focus. With significant untapped potential, geothermal energy offers a continuous, baseload power supply, unlike intermittent solar and wind. However, the pursuit of India’s geothermal policy necessitates a cautious and well-informed approach. This article delves into the various dimensions of this policy, highlighting both its promise and the critical considerations for its sustainable and effective implementation.

Understanding Geothermal Energy and India’s Potential:

Geothermal energy harnesses the Earth’s internal heat. This heat manifests in various forms, including hot springs, geysers, and subterranean reservoirs of hot water and steam. India is geologically diverse, with several regions identified as having significant geothermal potential. The Geological Survey of India (GSI) has identified over 300 hot springs, broadly classified into seven geothermal provinces. These include the Himalayan region (Puga and Chumathang in Ladakh), the Sohana Valley (Haryana), the Cambay graben (Gujarat), the West Coast (Maharashtra), the Godavari graben (Telangana and Andhra Pradesh), and the Son-Narmada-Tapti (SNT) graben (Madhya Pradesh). Developing these resources could provide a stable and environmentally friendly energy source, reducing reliance on fossil fuels and contributing to energy security.

Economic and Strategic Dimensions:

From an economic standpoint, geothermal power plants have high upfront capital costs but relatively low operational and maintenance expenses once established. This long-term cost stability can be attractive for grid stability. Strategically, developing indigenous geothermal resources enhances India’s energy independence, a crucial aspect of national security. It also aligns with India’s commitments under international climate agreements, showcasing its leadership in renewable energy adoption. Furthermore, geothermal projects can create local employment opportunities, particularly in remote regions where these resources are often located, fostering regional development.

Technological Challenges and Solutions:

The primary technological challenges in India include exploration risks, drilling difficulties in diverse geological conditions, and the need for advanced reservoir management techniques. Geothermal exploration is capital-intensive and requires sophisticated geological and geophysical surveys to accurately identify viable reservoirs. Drilling deep wells in hard rock formations can be challenging and costly. India needs to invest in R&D to adapt global best practices to its specific geological contexts and develop indigenous expertise in drilling and power plant construction. International collaborations and technology transfer will be crucial in overcoming these hurdles.

Environmental and Social Considerations:

While considered clean, geothermal energy is not entirely without environmental impacts. Issues like the release of greenhouse gases (though significantly lower than fossil fuels), land subsidence, and the disposal of geothermal fluids containing dissolved minerals need careful management. Proper environmental impact assessments (EIAs) and robust regulatory frameworks are essential to mitigate these risks. Socially, land acquisition for drilling and power plant infrastructure can lead to the displacement or disruption of local communities. Transparent compensation mechanisms, community engagement, and benefit-sharing models are critical to ensure social equity and obtain local consent.

Policy and Regulatory Framework:

India’s existing renewable energy policies have largely focused on solar and wind. A dedicated, comprehensive geothermal policy is imperative. This policy should offer clear guidelines for exploration licenses, resource assessment, environmental clearances, and financial incentives. The Ministry of New and Renewable Energy (MNRE) and the Ministry of Power need to collaborate effectively. A robust regulatory body capable of overseeing project development, ensuring environmental compliance, and resolving disputes would be beneficial. Long-term power purchase agreements (PPAs) with attractive tariffs are also crucial to incentivize private sector investment.

Recommendations for Careful Pursuit:

• Phased Approach: Begin with pilot projects in well-identified, high-potential areas to gain experience and refine technologies.
• Robust Resource Assessment: Invest in detailed geological and geophysical surveys to reduce exploration risks.
• Capacity Building: Develop a skilled workforce through specialized training programs and academic courses.
• Environmental Safeguards: Implement stringent EIAs and monitoring mechanisms to address potential environmental impacts.
• Community Engagement: Foster transparent communication and ensure equitable benefits for local communities.
• Financial Incentives: Offer tailored financial incentives, including grants, subsidies, and tax breaks, to de-risk investments.
• International Collaboration: Leverage global expertise and technology through partnerships with countries experienced in geothermal development.

Conclusion:

India’s geothermal potential presents an exciting opportunity to diversify its energy mix and achieve its sustainable development goals. However, as “The Business Standard” cautions, this journey must be undertaken with prudence. A well-crafted policy, backed by scientific rigor, technological advancement, strong environmental safeguards, and inclusive social practices, will be key to unlocking this subterranean power safely and sustainably. Only then can India truly “dig deep” into its geothermal reserves and harness their full potential for a greener, more secure future.
