ISR conducts surveys using 3D MT technology to set up India’s first geothermal power plant.
Q. Institute of Seismological Research has commenced surveys using 3-D MT imaging technology to set up India’s first geothermal plant through heat stored beneath the earth’s surface. What does MT stand for?- Published on 13 Oct 15a. Mettallotelluric
b. Magentotelluric
c. Statotelluric
d. None of the above
ANSWER: Magentotelluric
Institute of Seismological Research has commenced with surveys using latest 3-D magentotelluric imaging technology. The aim is to find spots for establishing the first geothermal power plant in India employing heat stored below the surface of the earth. Breakthrough is expected to lay the foundation of the geothermal power plant in Gujarat which will be the first of its kind in the country. Institute has also pioneered 3-D MT imaging of crust to locate optimal spots. So far, crustal structures and geological faults were being mapped in Kutch. Geothermal energy is stored beneath the surface of the earth in the form of heat which can generate power, as temperature below the earth will be as high as 100 to 150 degree C. Normal thermal power plants use coal or gas to generate steam and heat water, running the turbines. Pre heated water will be stored beneath the earth so that one does not have to rely on alternate energy sources. Currently, the focus is on locating spots where water with at least 80 degree C temperature can be obtained. This would be optimal for geothermal power plants.
