Eavor’s technology consists of several Patent Pending innovations. The Eavor-Loop is a closed system within which a proprietary working fluid is contained and circulated. The working fluid is not fluid from a reservoir flowing into our wells, it is a fluid added to the closed-loop Eavor-Loop™ to create an efficient radiator, much like a vehicle radiator circulates fluid in a closed-loop to remove heat from a gasoline engine.

Eavor-Loop™ harvests heat from deep in the earth to be used for commercial heating applications (ex: greenhouses or district heating) or to be used to generate electricity using conventional heat to power engines. Eavor-Loop™ is an industrial-scale geothermal system that mitigates many of the issues with traditional geothermal systems, which rely upon using wells to produce brine from a subsurface aquifer.

The closed-loop is the key difference between Eavor-Loop™ and all traditional industrial-scale geothermal systems. Eavor-Loop™ is a buried-pipe system, which acts as a radiator or heat exchanger. It consists of connecting two vertical wells several kilometers deep with many horizontal multilateral wellbores several kilometers long. As these wellbores are sealed, a benign, environmentally friendly, working fluid is added to the closed-loop as a circulating fluid.  This working fluid is contained within the system and isolated from the earth in the Eavor-Loop™. The wellbores act as pipes, not wells producing fluid from the earth.

The working fluid naturally circulates without requiring an external pump due to the thermosiphon effect of a hot fluid rising in the outlet well and a cool fluid falling in the inlet well.  The working fluid contained in this closed-loop pipe system brings thermal energy to the surface where it is harvested for use in a commercial direct heat application or converted to electricity with a power generation module (heat engine).

Unlike heat pumps (or “geo-exchange”), which convert electricity to heat using very shallow wells, Eavor-Loop generates industrial-scale electricity or produces enough heat for the equivalent of 16,000 homes with a single installation.

An excellent new video by CNBC entitled 'How Geothermal Energy Could Power The Future' features Eavor CEO, John Redfern and several others in the modern geothermal industry such as Catherine Hickson of Geothermal Canada, Tim Latimer of Fervo Energy, Cindy Taff of Sage Geosystems and Joe Scherer of GreenFire Energy.

The video covers topics such as:
- What is Geothermal energy?
- Geothermal startups gain traction
- Major opportunity for oil and gas
- The future of geothermal

"Miles below the Earth’s surface, there’s enough thermal energy to power all of humanity for the foreseeable future. It’s called geothermal energy, and it’s poised to play an increasingly large role as a source of always available, renewable power. Now, there are a number of startups in the geothermal space, working to figure out how to access this heat in difficult-to-reach geographies, at a price point that makes sense. And it’s even gotten the attention of oil and gas industry giants, who are interested in greening their portfolios while sticking to their core competencies - extracting energy resources from deep within the Earth."
