GEOTHERMAL ENERGY

Discuss the potential of geothermal energy in India and the challenges associated with its development.

Model Answer

Introduction

Geothermal energy uses the Earth’s internal heat to generate power and provide direct heating/cooling. It is renewable, low-carbon and available round the clock.

Potential

  • 6 GW theoretical potential → significant untapped resource.
  • 381 hot springs mapped across 10 geothermal provinces.
  • Puga Valley, Ladakh → first two geothermal wells commissioned.
  • Applications → electricity + heating/cooling + agriculture + aquaculture + geo-tourism.

Challenges

  • High exploration and drilling costs → commercial viability concerns.
  • Limited domestic expertise → reservoir management and advanced technology gaps.
  • Difficult terrain → infrastructure and accessibility issues.
  • Environmental risks → induced seismicity, water management and disposal of geothermal fluids.
  • Low deployment → commercial-scale projects still limited.

Government Initiatives

  • National Policy on Geothermal Energy, 2025 → framework for exploration and development.
  • R&D support → indigenous geothermal technologies and pilot projects.
  • GSHPs, EGS and AGS → expand applications and resource potential.
  • Abandoned oil/gas wells → potential geothermal reuse.
  • International cooperation → Australia, Iceland and Saudi Arabia.

Way Forward

  • Resource mapping → exploratory drilling → pilot projects → commercial deployment.
  • Promote PPP and risk-sharing mechanisms → reduce investment risks.
  • Develop indigenous drilling and reservoir technologies → lower costs.
  • Integrate geothermal with solar and other renewables → improve energy reliability.

Conclusion

Geothermal energy can complement solar and wind by providing reliable, indigenous clean energy → strengthening India’s energy security and supporting the Net Zero 2070 goal.
