Eavor Technologies Inc.
Eavor Technologies Inc. (pronounced “ev-er”) is a global geothermal technology company headquartered in Calgary, Alberta. Eavor Technologies was founded in 2017 with the goal of producing a scalable form of baseload, dispatchable energy.
Technology[edit]
Eavor-Loop[edit]
Eavor-Loop is a closed-loop geothermal energy extraction system that differs from traditional industrial-scale geothermal systems in several ways. Eavor-Loop is a buried well system consisting of two vertical wells several kilometers deep connected by an extended system of interconnected multilaterals. Multilaterals are drilled connecting the vertical wells, parallel to each other. The multilaterals are not cased with steel, but rather a polymer in the drilling mud is used to seal the inside of the pipe from the surrounding rock. This is done to increase heat extraction efficiency in the horizontal plane by exposing the system to a larger volume of rock. A benign working fluid is circulated within the completely contained system, which harvests heat from within the earth and brings it to the surface where it can be used for commercial heating applications or electricity generation. Circulation is added by the thermosiphon effect, where temperature differences between the upflowing and downflowing working fluid cause the system to circulate without pumps.
Environmental Impact[edit]
The key difference in Eavor’s geothermal technology is the closed-loop nature of the system. This mitigates many of the risks associated with traditional geothermal technologies, which use wells to produce brine from subsurface aquifers.
As a closed-loop system that operates in complete isolation from the surrounding environment, Eavor-Loop requires no fracking, produces no greenhouse gas emissions, poses no earthquake or subsidence risk, no water use, produces no brine or solids, and no aquifer contamination.
Facilities[edit]
Eavor-Lite Rocky Mountain house[edit]
The Eavor-Lite Demonstration Project[1] is a full-scale prototype of the Eavor technology suite located near Rocky Mountain House, Alberta.
Construction began in August 2019[2] and was completed in February 2020. Eavor-Lite consists of two vertical wells connected toe to toe, with one multilateral well drilled off the horizontal section, parallel to the original well.
The project was not intended to be commercially viable, but was designed to demonstrate critical elements of Eavor’s technology at the lowest cost to achieve the most efficient path to acceptance and commercialization of the technology.
Eavor Technologies announced the official completion and third party validation[3] of the Eavor-Lite demonstration project on February 5, 2020.
Projects [edit]
Eavor Yukon[edit]
In January 2020, Eavor Yukon announced a partnership[4] with Carmacks Development Corporation (CDC), owned by the Little Salmon Carmacks First Nation, to establish Eavor-Loop technology in the Yukon[5]
Geretsried, Germany Eavor-Loop Project[edit]
In May 2020, Eavor Technologies Inc. entered into a letter of intent[6] with Enex Power Germany GmbH to form a geothermal project development company to construct Eavor-Loop heat and power projects within Enex’s existing geothermal license area in Bavaria, Germany.
2020 Technology Development Program[edit]
In May 2020, Eavor Technologies Inc. announced the 2020 Technology Development Program[7]. The program includes the launch of second generation technology featuring a new demonstration site, Eavor-Long, in locations across Canada, France, Norway and the United States.
