What are the different types of Geothermal Power Plants?
There are mainly 3 different types of Geothermal Power Plants. We have listed them below as follows:
Dry steam Geothermal Power plants: The Geothermal Power Plants are built to utilize steam sourced directly from a geothermal reservoir. This steam at high temprature is used to rotate the generator turbines. this is the simplest design and no wonder why the very first geothermal power plant was built on this particular design in Italy at a place called Tuscany that too way back in 1904. This place has a natural source for steam emerging from under the earth.
Flash steam Geothermal Power plants: how does a Flash steam Geothermal Power plants work? This is a bit complex compared to the Dry steam Geothermal Power Plant discussed above. It is built on the principle of supplying high-pressure & hot water at high temperature from the earth and transform it into steam. Again, this steam is used to turn the generator turbines. The interesting part for this design of Geothermal Power Plant is the reusability of steam. After the steam has turned the turbines, it cools down. This steam is then condensed to water again and this water is once again sent back to the ground allowing reusability and energy efficiency. This is why most geothermal power plants across the globe follow this pattern and are flash Geothermal Power plants.
Binary power Geothermal Power plants: How does a Binary power Geothermal Power plants work?
Though not very common, but as the name suggests they use 2 different liquids. Everything remains the same except the fact that the heat generated is transported to another liquid - which is expected to turn the turbines with a better efficiency. It is this second liquid which turns the turbine blades of the Geothermal Power Plant.
How do the Geothermal Heat Pumps Work?
The Geothermal heat pumps utilize the temperature difference between the earth and the climate above it. Though our atmosphere temperature varies a lot based upon the season and solar heat, the temperature of the earth surface upto a few feet beneath remains almost constant regardless of the season. It is reported to be in the range of 50 to 60 degree F. Hence, the Geothermal Heat Pumps tend to utilize the temperature differential between these 2 locations and generate energy. We will provide an article about Step by step guide to installing Geothermal Heat pumps at home.
Geothermal heat Pumps are really efficient, energy savings, do not harm the environment and are perfect match for alternate energy fuel
