Northeast's first geothermal well drilled in Dirang, paves way for sustainable energy

1 2 3 4 5 6 Itanagar: The Centre for Earth Sciences and Himalayan Studies ( CESHS ) has successfully drilled the northeast's first geothermal production well at Dirang in Arunachal Pradesh 's West Kameng district, an official said. The successful drilling marks a milestone in the region's quest for sustainable energy and represents a first-of-its-kind initiative in the northeast, CESHS Geosciences Division head Rupankar Rajkhowa said on Monday. He said the achievement follows two years of intensive geochemical and structural surveys of hot springs across western Arunachal Pradesh. Once operational, the geothermal energy will power eco-friendly solutions including fruit, nut, and meat drying, space heating, and controlled-atmosphere storage systems. These are vital technologies for improving agricultural and living conditions in the high-altitude terrain of the state, he said. The project is the result of international scientific collaboration between CESHS, the Norwegian Geotechnical Institute (NGI), Oslo, Norway, the Icelandic geothermal firm Geotropy ehf, and the drilling team from Guwahati Boring Service (GBS). by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Pernas e pés inchados: Experimente isso para ajudar a drenar o fluído do edema aartedoherbalismo Undo Through advanced geochemical analysis, the Dirang region has been identified as a medium-to high-enthalpy geothermal zone. Reservoir temperatures are estimated at 115°C using mixing models, making it highly suitable for direct-use geothermal applications. Structural and geological mapping in the Dirang area revealed quartzite overlying schist at tectonic contacts near the Main Central Thrust (MCT), consistent with extensional normal faults found elsewhere in the higher and lesser Himalayas. These insights have enabled precision drilling to access the geothermal reservoir with minimal environmental impact. This breakthrough project is supported by the Arunachal Pradesh govt and the ministry of earth sciences, Rajkhowa added. With the first production well completed, CESHS plans to scale operations with deeper drilling in Dirang, potentially making it India's first geothermal-powered city for space heating, he said. "This pioneering development paves the way for a new era of clean energy in the Himalayas," said CESHS director Tana Tage. "It demonstrates the potential of geothermal resources in transforming regional livelihoods while ensuring environmental sustainability," he added. The CESHS is an autonomous organisation under the department of science & technology, Arunachal Pradesh govt.
