2. What is Geothermal Energy?
 Geothermal energy is the thermal
energy produced and stored in the
center of the Earth.
 Higher temperature at the earth’s inner
core due to radioactive decay of
materials.
 Utilize temperature of the earth’s core.
(Temperature difference)

3. Geothermal Reservoirs
 Reservoirs can be suspected in the
areas where we find:
 Geyser
 Boiling mud pot
 Volcano
 Hot springs

4. Ring of Fire
 The Ring of Fire is a major area in the
basin of the Pacific Ocean where many
earthquakes and volcanic eruptions
occur.
 Over 20 countries
 San Andreas Fault
 United states
(Greatest geothermal energy Production)

5. Formation of Geothermal Energy

6. Applications
 Domestic usage:
• Ironing
• Hot bath
• Heating in individual housing
• Hot water pools
• Air conditioning

7. Applications
 Heat production (via heat pump or direct heat exchange)
 Power production (via steam turbine)
 Stimulated Geothermal Systems technology (SGS) (Energy extracted by the
formation of rocks) [Future]

8. Geothermal Powerplant
 Utilizing geothermal energy to
generate electricity.
 Manifested in 1904 in Italy.
 First successful large scale geothermal
powerplant - Geysers, California(1960)
 USA produced 3450 MW in 2015.

9. Power Generation
 Three cycles which power plant uses
to produce power.
1. Dry steam cycle
2. Flash steam cycle
3. Binary cycle

10. Geothermal Energy in India
 Exploration started at 1970
 GSI (Geological survey of India)
Total 350 locations identified.
Ladakh, Himalayas, Cambay, etc.
 Estimated potential = 10000 MW

11. Advantages
 Environmental Friendly
 Provide constant power
 No fuels required
 Number of applications

12. Disadvantages
 Heat must be taken care properly
 Cost of powering the pump
 Specific locations
 Surface stability
(Geothermal powerplant in Switzerland
triggered 3.4 Richter earthquake)
