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.

Khangri Glacier expedition: Jt team assesses its condition and climate change response
1 2 3 4 5 Itanagar: A comprehensive risk assessment of Rani Lake in Tawang district, identified by the National Disaster Management Authority (NDMA) as a category-B glacial lake with the potential to trigger glacial lake outburst , concluded on Saturday. The assessment was undertaken by a joint team from the Centre for Earth Sciences and Himalayan Studies (CESHS), Itanagar, the National Centre for Polar and Ocean Research (NCPOR), Goa (under the Union ministry of earth science) and the Indian Institute of Technology, Guwahati. The expedition to the Khangri Glacier, in the Gorichen mountain region, started from April 19 and concluded on Saturday, CESHS director (earth sciences) Tana Tage said. Key activities included glacier mass balance measurements at 5,032 meters above sea level (msl) to assess the glacier's condition and its response to climate change, Tage said. The assessment involved a bathymetric survey to determine the lake's depth and volume, coupled with terrain observations, to evaluate the stability of moraines, drainage pathways and potential downstream hazards. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Co-Founder of Google Brain, Andrew Ng, Is Reported To Have Read Every... Blinkist: Andrew Ng's Reading List Undo To ensure continuous climate monitoring, the team also performed maintenance on an Automatic Weather Station (AWS) and successfully retrieved data collected over the winter, Tage said. Furthermore, the team maintained water level sensors and conducted direct measurements of glacier meltwater discharge, enabling an accurate assessment of the total run-off from the glacier system. In a first-of-its-kind initiative, the team also conducted a reconnaissance survey of a cluster of category-B glacial lakes, located at an altitude of 5,300 msl. These lakes, identified by the NDMA, were assessed for their risk potential to inform future hazard mitigation and disaster preparedness strategies. To facilitate future expeditions, the team also identified a suitable site at Mirathang for establishing a long-term high-altitude field research station, Tage said.
