00:00The geothermal power project is currently being studied in Ladakh and Puga.

00:07In collaboration with Iceland and ONGC, a pilot project of 1 megawatt is currently in drilling mode.

00:19It is the most feasible site for geothermal exploration.

00:26The tectonic setup is very different from that of Uttarakhand.

00:36There is a huge difference in the availability of geothermal resources and subsurface reservoirs in Uttarakhand and Ladakh.

00:48There are three types of geothermal reservoirs in the world.

00:51One is deep source, shallow source and mid-source.

00:56For example, Ladakh is mid-source.

00:59Uttarakhand and Himachal and the north-east portion is shallow source.

01:07Shallow source means it has no connection with the mantle or deep source of energy.

01:14Some geothermal anomalies occur near the subsurface.

01:19Suddenly, the geothermal gradient increases.

01:24Due to the artesian condition, geothermal activity is observed.

01:29There are 30 to 40 such locations in Uttarakhand.

01:34But it is quite difficult to produce electricity from them in the present scenario.

01:41All the fields in Uttarakhand are green fields.

01:45No one has conducted an intense survey to find out how much electricity can be produced from them and what are the possibilities.

01:52In my 10 years of research, I have done reservoir and resource assessment.

01:59The maximum reservoir temperature is between 220 to 140 degrees centigrade.

02:09The maximum depth in Uttarakhand is between 1 to 2 kilometers.

02:15You can establish a pilot project from there.

02:21But how much electricity will be produced?

02:23We cannot tell until an intense survey is conducted and drilling is done.

02:29As you said, Iceland is also a green field.

02:36I was in the Icelandic deep drilling program.

02:41They made 5 wells.

02:43The maximum depth was estimated to be 5 kilometers.

02:4670% of the wells were unsuccessful.

02:50Geothermal is a very difficult business.

02:54Luck also plays a big role in this.

02:56It depends on how much gradient you are getting and how long you are getting it.

03:00A conclusion can be reached only after a thorough study.

03:04A lot of people talk about Jyoti Math.

03:09It has a surface temperature of 90 degrees centigrade.

03:12Maybe they don't know that in 1970, the Geological Survey of India drilled there up to 450 meters.

03:20After drilling from 450 to 550 meters, the temperature they got was 90 degrees centigrade.

03:26We are getting it on the surface today.

03:29Leave alone Yamunotri, where the temperature is 89 degrees centigrade.

03:35That is the natural temperature in the entire Uttarakhand region.

03:38But the temperature we are getting on the surface of Jyoti Math is due to drilling, not due to its natural condition.

03:45After drilling 450 meters, we got this much temperature.

03:49The reservoir depth is 1 to 1.5 kilometers.

03:54When you drill from 1 to 1.5 kilometers, you will get a temperature of 120 to 130 degrees centigrade.

04:00The availability and discharge of water depends on how many megawatt turbines you can run and how much vapor you can make.

04:10You cannot make direct electricity there.

04:13There is a binary power plant where there is another source whose boiling temperature is less than that of water.

04:20In that, we make vapor from propane and other gases.

04:24Then we run that turbine.

04:26It is not possible to produce electricity directly from geothermal energy in India.

04:31It is possible that if we produce electricity from a single source, it will cost a lot.

04:38If we include both solar and geothermal as a hybrid model and make a policy like this,

04:44and adopt it scientifically, we can do a lot for Uttarakhand.

04:51There are two topics.

04:53One is geothermal policy.

04:54We have prepared a policy draft.

04:56We are taking opinions from the relevant departments.

04:59After this, it will be presented to the Minister.

05:03Secondly, you are talking about the MoU with Iceland.

05:08Iceland is the world leader in geothermal energy.

05:1380% of the energy in that country is coming from that source.

05:19In this, there was a proposal from Iceland.

05:23They have a consulting agency called Verkis.

05:26We don't have to fund it.

05:28The government of Iceland will do it.

05:30They will give us a feasibility study of one site.

05:34The MoU has to be signed.

05:36When the MoU was given, since it is another country,

05:40we asked for permission from the external affairs ministry of the 12th government.

05:49They took the MoU from the non-traditional energy ministry,

05:53MOEF, and finally gave us a proposal.

05:57The MoU signing ceremony will be in January.

06:00The ambassador is not here.

06:04He has gone to Iceland.

06:06He will come back around 15th January.

06:09We will meet after that.
