How Is Geothermal Energy Generated Step By Step
When the water reaches the surface the pressure is dropped which causes the water to turn into steam. Geothermal energy keeps your home at an optimal and comfortable temperature by either pulling warmth from the earth or pulling warmth from your home back to the earth.

Hot pressurized geothermal fluid or a secondary working fluid is allowed to expand.
How is geothermal energy generated step by step. Gathering and evaluation of existing data O Step 2A. In the past this hot water was simply discarded. This return of materials is safe and completes the loop making geothermal energy a renewable energy source.
STEP Energy will leverage its partners expertise to develop efficient and profitable geothermal power generation projects providing an opportunity. Some power plants pipe the steam directly up to the generator. In the first step cold water is pumped down 45 km underground through the injection well.
Dry steam flash steam and binary cycle. In the United States about 25 billion barrels of hot water are produced every year as a byproduct. Schlumberger New Energy a new Schlumberger business and Thermal Energy Partners TEP have entered into an agreement to create STEP Energy a geothermal project development company on Aug.
Exploration drilling O Step 3. Geothermal power plants use geothermal resources to drive electrical generators. This is typically done by pumping very hot water under high pressure from as deep as one or two miles underground.
Power plants take advantage of extremely hot water that is between one and two miles deep in the Earth. Surface exploration O Step 2B. Generating electricity - Finally geothermal energy can be used by power plants to create electricity.
Geothermal energy involves the transfer of the natural heat of the earth to your home or business or the transfer of heat from your home or business back to the earth. Feasibility report O Step 7. How geothermal energy works is we capture this steam and produce power in one of the following five ways.
How a Geothermal Power Plant Works Simple - Text Version Wells Are Drilled. A production well is drilled into a known geothermal reservoir. This form of geothermal energy uses water that has been heated as a byproduct in oil and gas wells.
The steam rotates a turbine that activates a generator which produces electricity. Steam Turns the Turbine. Dry steam power plants draw from underground resources of steam.
Ocean thermal energy conversion OTEC systems use a temperature difference between ocean water at different depths to power a turbine to produce electricity. These plants tap into the much higher temperatures deeper inside the planet to generate electricity. There are three basic designs for geothermal power plants all of which pull hot water and steam from the ground use it and then return it as warm water to prolong the life of the heat source.
Geothermal Power Plants Hot water is pumped from deep underground through a well under high pressure. Co-produced geothermal energy technology relies on other energy sources. Overall there are five steps in the process starting from pumping down cold water into the geothermal zone to producing electricity from the generator which is then sent into the electrical grid.
The steam spins a turbine which is connected to a generator that produces electricity. Pre-feasibility report O Step 4. There is a demonstration OTEC system in Hawaii.
There are a few more moving parts to a geothermal power plant. In the simplest design known as dry steam the steam goes directly through the turbine then into a condenser where the steam is condensed into water. They are called dry steam power plants.
Geothermal energy capture is accomplished by using a large turbine. Design construction production drilling. Typically an injection well is also.
Sometimes a secondary working fluid expands from the heat introduced from the ground in order to deliver rotational or mechanical energy to the turbine blades. Drilling and testing of confirmation wells O Step 6. Once the power generates pumps return the water to the earth via a process of injection wells.
Environmental assessment O Step 5. There are three types of geothermal power plants. The turbine spins and delivers energy to the generator the expansion of hot fluids from inside the Earth create steam.
Other types of generators.
