ABSTRACTABSTRACT

Indian geothermal provinceshave the capacityto produce 10,600 MW of power-

A figure Which is five times Greaterthan the combined powerbeing produced from non-

conventional Energy Sourcessuchas wind, solarand biomass. But geothermal power

projectshave notseen the Sunlight due the availability of 192 billion tones ofrecoverablecoal Reserves. Indiahasto be depend upon with escalating environmental problems with

coalbased projectsare Increased; India hasto depend upon clean, cheap, ruralbased

and eco-friendly geothermal power in future. Present day industrialistsand (Independent

powerProducers) IPPsare showing keen interests in developing geothermalbased power

projects due to the technicaland logistic problems withthe otherNon-conventional Sources.

The future of geothermal energysectorin Indiaappearsto be brightasthe existing open

economic policy ofthe government, Large incentivesare being given to Non-conventionalsector.

METHODOLOGYMETHODOLOGY

Direct uses of geothermal energy are appropriate for sources below 1500C:

Direct Sources Of Work:

Ground Heat Collectors

Bore hole Heat Exchange

Generation of Electricity is appropriate for sourcesGreater than 150o C.

1. Dry Steam Plants:

First Type of Plants

Underground Steam

Directly turn turbines


7/14

2.Flash Steam Plants:

Most commonly used plants

These systems pull deep, high pressured hot water that reaches temperatures of 3600F

or more to the surface.

This water is transported to low pressure chambers, and the resulting steamdrives the turbines.

The remaining water and steam are then Injected back into the source from

which they were taken

3. Binary- Cycle Power Plant:

This system passes moderately hot geothermal water past a liquid, usually an organic

fluid, that has a lower boiling point.

The resulting steam from the organic liquid drives the turbines.The water temperature needed for the water is lower than that needed in the

Flash Steam Plants (2500F 3600F).

Emission Free.


9/14

Hot Dry Rocks:

It Consists of two wells:

one Injection Well

Two Production well

Working: Pressurized cold water is sent down the injection well where

the hot rocks heat the water up.

Then pressurized water of temperatures greater than 2000F is brought to

the surface and passed near a liquid with a lower boiling temperature, such

as an organic liquid like butane.

The ensuing steam turns the turbines. Then, the cool water is again injected to be heated.

This system does not produce any emissions.

RESULTS AND DISCUSSIONRESULTS AND DISCUSSION

Geo-thermals Positive Attributes:

Extraction Of useful Minerals

Better Global Trading Position

Emission ofGases from the plant

Geothermal Electric plant production

Absence of gaseous emissionRequirement of geothermal plants

Availability of Geothermal Energy:

Near volcanoes, hot springs and fumaroles

Electricity over thirty years.

Estimation OfGeothermal Energy

Production OfGeothermal Energy

Iceland is one of the more countries successful in using geothermal energy:

86% of their space heating uses geothermal energy.

16% of their electricity generation uses geothermal energy


11/14

Harmful Effects of Geothermal Energy:

Increase Of seismic Activity

Drilling operation is noisy

Overall efficiency Is low

Release of H2s gas

Brine can salinities in the soil

CONCLUSIONCONCLUSION

Conserve the energy and use it efficiently.

To create the new energy technologies for the future.

Development Of Renewable Energy Sources.

Usage of solar, wind, geothermal, wave power and hydrogen. Replacing of Cleaner technologies by using fossil fuels

and nuclear energy

Educate the people regarding various aspects of renewable

energy using multimedia.
