Geothermal (EARTHSCI)

Geothermal Energy

Energy that comes from the ground

Geothermal Energy

Power extracted from heat stored in the earth

Earth; Heat

Geo; Thermal

Paleolithic times

Used for bathing in _____

Ancient Romans

_____ used it as a central heating system for bathing and heating homes and floors

Hot Water Reservoirs

These are reservoirs of hot underground water

Natural Steam Reservoirs

In this case a hole dug into the ground can cause steam to come to the surface

Geopressured Reservoirs

In this type of reserve, brine completely saturated with natural gas in stored under pressure from the weight of overlying rock

Dry Steam Powerplants

These were the first type of powerplants created

Flash Steam Powerplants

These are the most common type of powerplants

Binary Cycle Plants

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.

Bac-Man Geothermal Production Field

It is one of the geothermal power stations operated by Energy Development Corporation

The Geysers

It is the world's largest geothermal field

83.3 million

Electricity generated by geothermal plants saves _____ barrels of fuel each year from being burned worldwide

40.2 million

This prevents ____ tons of carbon dioxide from being emitted into the atmosphere

103.6 million

Direct use of geothermal energy prevents _____ barrels of fuel each year from being burned worldwide

49.6 million

This stops _____ tons of carbon dioxide from being emitted into the atmosphere

Hot Water Reservoirs

There is a large amount of them in the US, but they are more suited for space heating than for electricity production

Geopressured Reservoirs

This type of resource can be used for both heat and for natural gas

Dry Steam Powerplants

They use underground steam to directly turn the turbines

Dry Steam Powerplants

This type of power plant is not common since natural hydrothermal reservoirs dry steam are very rare

Flash Steam Powerplants

These systems pull deep, high pressured hot water that reaches temperatures of 360°F or more to the surface. This water is transported to low pressure chambers, and the resulting steam drives the turbines. The remaining water and steam are then injected back into the source from which they were taken.

Binary Cycle Plants

This process does not produce any emissions and the water temperature needed for the water is lower than that needed in the Flash Steam Plants (250°F – 360°F)
