Almost everywhere, the shallow ground or upper 10 feet of the Earth’s surface maintains a nearly constant temperature between 50° and 60°F (10° and 16°C). Some geothermal power plants use the steam from a reservoir to power a turbine/generator, while others use the hot water to boil a working fluid that vaporizes and then turns a turbine. Geothermal energy content for this section provided in part by the National Renewable Energy Laboratory and the Department of Energy. Middle temperature: Despite these reservoirs have a lower temperature compared to the high temperature ones, they allow extracting sufficient heat to produce electricity (but with lower performances) using a volatile fluid. Hydrothermal resources contain superheated water, steam, or both in fractures or porous rock but further trapped by a layer of impermeable rock.. Please consult a translator for accuracy if you are relying on the translation or are using this site for official business. By powering your house with a geothermal heat pump you can make use of ground temperatures to either cool (in summers) or heat your house (in winters). The steam eliminates the need to burn fossil fuels to run the turbine. The exploitation in hydrothermal form is one of the techniques of recovery of this energy. Direct use and district heating systems use hot water from springs or reservoirs located near the surface of the earth. Examples of different types of geothermal reservoirs exploitation: 1) High temperature: In a deep granitic basement beneath a sedimentary cover (ratio units with a thermal conductivity contrast promotes the geothermal gradient), cold water is injected and hot water is extracted in such a way that in contact with a second surface circuit, it generates hot steam for electricity production. The recovered heat is not sufficient and must be upgraded by a heat pump to supply radiators or underfloor heating. On the Swiss Plateau, the water temperature between 1 and 4 kilometers deep reaches between 40° and 130° Celsius. Thus, four types of geothermal reservoirs can be defined: High temperature:  These reservoirs provide enough heat to make electricity from steam profitably. Then, stimulation is carried out with water under high pressure to improve the permeability of this rock. There are three types of geothermal power plants: dry steam, flash steam, and binary cycle. Geothermal wells are wells which tap into the natural geothermal energy found beneath the Earth's crust. Drilling is done to reach this rock. : Any leftover water and condensed steam are injected back into the reservoir, making this a sustainable resource. Binary cycle power plants operate on water at lower temperatures of about 225°-360°F (107°-182°C). All of these work in the same way. Please refer to the Energy Commission's website Conditions of Use. Open-loop systems can be used all over the world because of the temperature remaining constant underground. And this heat will spread out into the Earth’s layers. Other than these benefits, geothermal energy is much cheaper than other renewable sources of energy in the long run. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth’s surface, and down even deeper to the extremely high temperatures of molten rock called magma. In winters, the electric compressors use the heat derived from the mixture to heat air and send it through ducts into the building. Geothermal energy is a form of renewable energy since the Earth’s core will always be radiating heat! The Institut Cartogràfic i Geològic de Catalunya allows the reuse of content and data without restrictions beyond mention of the source, non-alteration of information and specification of last update, and so long that it does not contradict any license. In the United States, most geothermal reservoirs of hot water are located in the western states, Alaska, and Hawaii. 2. There are three main types of geothermal energy systems: Direct use and district heating systems ; Geothermal power plants ; Geothermal heat pumps; Direct use and district heating systems. Essentially, geothermal resources available in Switzerland can be described as follows. Currently, there are no commercial applications of this technology. Text and graphics from U.S. Department of Energy's Office of Energy Efficiency & Renewable Energy. Moderate-temperature water is by far the more common geothermal resource, and most geothermal power plants in the future will be binary-cycle plants. Geothermal electricity generation is currently used in 26 countries, while geothermal heating is in use in 70 countries. It heats up in contact with the heat of the subsoil and then rises to the surface. Your email address will not be published. This heat radiates out of the core in all directions and raises the temperatures of other layers of the Earth. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. The heat reservoirs underground help the plant to pump hot steam into turbines which spins them; this process then powers the generator to provide electricity.
