Soon, power from ancient rocks- Dr Ritesh Arya

CHANDIGARH: For the hill state of Himachal Pradesh looking for energy solutions, the future lies in the rocks buried beneath thousands of metres.

A drilling project in the cold desert of Ladakh in Chumathang area by the Geological Survey of India and DRDO on the sites identified by team of scientists from Norway Iceland lead by Dr Ritesh Arya during Agneyodgara Indor Puga Geothermal Expedition of 2011 has warmed the prospect of harnessing energy from millions of years old molten rocks.                                                                     http://articles.timesofindia.indiatimes.com/2012-02-05/goa/31026765_1_alternative-energy-renewable-energy-geothermal-energy


In the future, metros like Delhi, Mumbai, Chennai and Hyderabad too might be exploring the heat generated from the rocks buried in the earth to light up houses.

The Indian Army in Ladakh is already working towards growing vegetables in greenhouses warmed with geothermal energy in inhospitable terrain of Himalyas, where temperatures routinely dip to over minus 20 degrees Celsius. Not just this, the heat derived from the rocks will be used to warm houses and community buildings like schools.

Ritesh Arya, hydrogeologist and the man behind the country’s first geothermal energy project, has floated the idea globally. The man who made a record that went into the Guinness Book of World Records, by finding water at the highest altitude of over 14,000 feet, will be presenting the Agneyodgara  model at the World Future Energy Summit, scheduled to be held in Abu Dhabi next week.

“Apart from Himalayas we have identified Delhi, Mumbai, Chennai and Hyderabad as potential geothermal energy sites because of the geotectonic zones these cities fall in. They have granite rocks which means there was some volcanic activity here in the past. We hope to get temperatures of 200 to 300 degrees centigrade if we drill four to five kilometres deep into the earth,” says Ritesh Arya.

A project has been done in collaboration with the government of Norway that allocated 1.5 million krones to explore and tap geothermal energy in Himalaya.


The team compromising of scientists fromNorway,Icealnd and Indian Institutes and Universitires led by Dr Ritesh Arya had identified Chumathang,Puga,Manikaran,Tatapani as not only potential geothermal sites for power generation but also promotion of tourism activities. (Indian Norwegian venture proposes geothermal development in 3 locations in India – Dr Ritesh Arya)    http://thinkgeoenergy.com/archives/10096

“In Delhi the rocks are 500-600 million years old, in Mumbai, the rock belt is 50-60 million years old, while Chennai has the oldest rocks dating back to nearly a billion years. 10000MWe is the known geothermal potential of India but if Agneyodagra sites concept of developing Lava Energy at shallow depths proposed by Arya are developed then potential can run into giga watts from over 400 sites in the country,” says Arya, who presented his findings of providing SAFE,FREE, sustainable renewable Energy for all by 2050 in United Nations International Sustainable Energy Convention in Geneva early 2012 and was ranked among the top 10 innovators by Guardian. http://www.guardian.co.uk/environment/blog/2011/jan/19/top-10-renewable-energy-companies

The geothermal energy model being mooted is simple. “Drill deep into the earth, like now it is being done for oil. At about 4 km depth, the temperatures would be 200 to 300 degree centigrade. Pour the entire sewerage water of the city into these borewells, which will generate steam that in turn will rotate turbines and generate electricity,” says Arya, giving the urban model of geothermal energy.ergy.p
