A geothermal reservoir is a powerfulsource of energy

Geothermal reservoirs can

reach temperatures of 370 C.

(more than 3 times boiling).

Generation Of Electricity


13/29


14/29

Dry Steam Power Plants

The steam goes directly to a

turbine, which drives a

generator that produces

electricity.

This is the oldest type of

geothermal power plant.

The steam eliminates the

need to burn fossil fuels to

run the turbine.

Today after 90 years, the Lardello field is still producing


16/29

Flash Steam Powerplants

It utilizes hydrothermalfluids above 400 degrees F

that can be used in flash

plants to make electricity.

Fluid is sprayed into a tank

held at a much lower

pressure than the fluid,

causing some of the fluid to

rapidly vaporize, or "flash,"

to steam.

The steam eliminates the

need to burn fossil fuels to

run the turbine.


17/29

Binary Cycle Power Plant

Hot geothermal fluid and asecondary fluid with a much

lower boiling point than

water pass through a heat

exchanger.

Heat from the geothermalfluid causes the secondary

fluid to flash to steam,

which then drives the

turbines.

Most geothermal power

plants in the future will be

binary-cycle plants.

Those white plumes you see at geothermalpower plants are steam (water vapor).Geothermal plants do not burn fuel orproduce smoke.

Easy on Environment


20/29

People who live in these areas are receivingelectricity from geothermal power plants.There are around 24 countries using geothermal energy to

produce electricity. Prominent names are USA, Philippines,Mexico, Indonesia, Italy, Japan, New Zealand, Iceland, Costa

Rica, Kenya, EI Salvador, Nicaragua, Guatemala, Turkey and

France. Among them USA has the highest production of 17917

GWh/year. Countries like Philippines with 18.8%, Iceland 17.5%and EI Salvador 22% having the most prominent percentage of

geothermal power in their total energy production.

There are EGS systems currently being developed and tested

in France, Australia, Japan, Germany, USA and Switzerland.There are several EGS projects that are already or will soon

produce power.

Costs


23/29

The significant costs associated with an EGS project are:

Drilling cost.

Reservoir stimulation.

Power plant.

Transmission and other regulatory costs.

Wells in the depth ranges from 1,500 m to 10,000 m were

modeled in three categories: shallow wells (1,500-3,000 m),

midrange wells (4,000-5,000 m), and deep wells (6,000-10,000

m). Well costs were estimated for depths from 1,500 m to

10,000 m.


24/29

EGS is receiving attention in the world stage because of its

lower operation and maintenance cost, environmental

cleanliness and relatively lower cost of the energy produced.

Geothermal Heat Pumps(GeoExchange systems)


26/29

Geothermal heat pumps can be used almost everywhere in

the world, without a geothermal reservoir. The insulating

properties of the earth, just below our feet, can keep us warm

or cool.

In a poll, over 95% of people who had installed a geothermalheat pump said they would recommend it and would do it

again.
