Closed-loop Geothermal
Closed-loop geothermal systems (also known as “advanced geothermal systems” or “AGS”) are a type of engineered geothermal energy system containing subsurface working fluid that is heated in a hot rock reservoir without direct contact with rock pores and fractures.: Instead, the subsurface working fluid stays inside a closed loop of deeply buried pipes that conduct Earth’s heat. Closed-loop geothermal systems are one of the prominent categories of next-generation geothermal systems in development today. Like all geothermal systems, closed-loop geothermal systems provide renewable energy, and primarily operate as baseload resources that produce energy at a constant rate. Unlike conventional geothermal energy plants, closed-loop geothermal plants can be placed anywhere in the world, depending only on the depth of the hot rock resource. Closed-loop geothermal projects are under development in the United States, Canada, Japan, and Germany. Technology Closed-loop geotherma ...

Geothermal Energy
Geothermal energy is thermal energy extracted from the crust (geology), crust. It combines energy from the formation of the planet and from radioactive decay. Geothermal energy has been exploited as a source of heat and/or electric power for millennia. Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times and for space heating since Roman times. Geothermal power (generation of electricity from geothermal energy), has been used since the 20th century. Unlike wind and solar energy, geothermal plants produce power at a constant rate, without regard to weather conditions. Geothermal resources are theoretically more than adequate to supply humanity's energy needs. Most extraction occurs in areas near tectonic plate boundaries. The cost of generating geothermal power decreased by 25% during the 1980s and 1990s. Technological advances continued to reduce costs and thereby expand the amount of viable resources. In 2021, the US ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
