The 17 potential sites explored in Gujarat by the researchers areDholera,Unai, Gandhar, Chabsar, Ghogha, Harsani, Kawi, Khedpada, Khar, Maktapur, Warha, Mithapur, Tuwa, Tulsishyam, Savarkundla, Lasundra and Lalpur.
The sites were chosen based on geophysical surveys of gravity, Magnetism, seismic activity and magneto-telluric surveys. In the majority of the cases, hot water springs are surface manifestation of .
The atlas was created by theCentre of Excellencefor Geothermal Energy (CEGE) at PDEU, and is in the final stage before it is submitted to the State Government for further exploration.
CEGE is already working at Dholera and Unai. At Unai, the team has found the hottest well in Gujarat with a surface temperature of 70 degrees celsius. The Centre of Excellence is also working on projects to showcase the capacity of geothermal energy for food drying and balneology (the medicinal effects of hot water springs).
