  2. Closed-loop geothermal - Wikipedia

    en.wikipedia.org/wiki/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.: [1] [2] [3] Instead, the subsurface working fluid stays inside a closed loop of deeply buried pipes that conduct Earth’s ...

  3. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    A closed pond loop consists of coils of pipe similar to a slinky loop attached to a frame and located at the bottom of an appropriately sized pond or water source. Artificial ponds are used as heat storage (up to 90% efficient) in some central solar heating plants, which later extract the heat (similar to ground storage) via a large heat pump ...

  4. Geothermal energy - Wikipedia

    en.wikipedia.org/wiki/Geothermal_energy

    Instead, the subsurface working fluid stays inside a closed loop of deeply buried pipes that conduct Earth's heat. The advantages of a deep, closed-loop geothermal circuit include: (1) no need for a geofluid, (2) no need for the hot rock to be permeable or porous, and (3) all the introduced working fluid can be recirculated with zero loss.

    en.wikipedia.org/wiki/Glossary_of_geothermal...

    Unlike the closed loop in a Ground Source Heat Pump, which is used for small-scale residential heating and cooling, Closed-Loop Geothermal Systems are used for utility-scale energy production (typically >1 megawatt). A Closed-Loop Geothermal System is sometimes referred to as an Advanced Geothermal System (AGS).

  6. Direct exchange geothermal heat pump - Wikipedia

    en.wikipedia.org/wiki/Direct_exchange_geothermal...

    DX system being drilled in the 1980s. A direct exchange (DX) geothermal heat pump is a type of ground source heat pump in which refrigerant circulates through copper tubing placed in the ground unlike other ground source heat pumps where refrigerant is restricted to the heat pump itself with a secondary loop in the ground filled with a mixture of water and anti-freeze.

  7. International Ground Source Heat Pump Association - Wikipedia

    en.wikipedia.org/wiki/International_Ground...

    Established in 1987, the International Ground Source Heat Pump Association (IGSHPA) is a nonprofit, membership-based organization that promotes geothermal heat pump technology. It was a outreach unit of the College of Engineering, Architecture and Technology (CEAT) at Oklahoma State University until 2020. In June 2020, the OSU Board of Regents ...

  8. Eavor Technologies - Wikipedia

    en.wikipedia.org/wiki/Eavor_Technologies

    The Eavor-Loop™ differentiates Eavor’s technology from conventional or Enhanced Geothermal Systems (EGS). This closed-loop system acts as a subsurface reverse radiator, where a working fluid circulates through a series of multilateral wellbores and extracts heat from hot rock via conduction. The system brings thermal energy to the surface ...

  9. Enhanced geothermal system - Wikipedia

    en.wikipedia.org/wiki/Enhanced_geothermal_system

    An enhanced geothermal system (EGS) generates geothermal electricity without natural convective hydrothermal resources. Traditionally, geothermal power systems operated only where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction. [ 1 ]
