Founded in 2017, Eavor Technologies inc. is a key player in the future of geothermal technology in Canada. Utilizing traditional oil and gas expertise and assets to transform power production to a 24/7 carbon-free energy future. This page will guide you through Eavor’s inception, evolution, noteworthy accomplishments, media assets, and much more.
Focusing on the previous traditional geothermal energy production in previous years, a typical geothermal power plant works by drilling down into a naturally occurring underground reservoir of hot water, normally in volcanic regions. This hot water is pumped to the surface and turns into steam when it returns to atmospheric pressure, driving an electricity-generating turbine. The steam is then cooled, and the cold water is pumped back into the underground reservoir to be reheated.
A so-called low-enthalpy geothermal energy (LEGE) plant has similar principles but does not utilize underground hot-water reservoirs — it simply pumps water down to a depth of 1-5km and uses the hot rock to heat the water, which is then pumped back to the surface to power an Organic Rankine Cycle (ORC) electricity-generating system. But according to Eavor CEO, John Redfern, LEGE has never taken off because the amount of energy needed to pump the heated water to the surface and later reinject it equates to 50% or more of the electricity the plant generates.
The idea for Eavor-Loop™ came from the company’s co-founder and now chief business development officer, Paul Cairns, during a chat with Redfern in 2017 about how suspended oil wells in Alberta could be re-used for profit — a conversation which then turned to LEGE.
“Luckily for us, my co-founder wasn’t an engineer, he wasn’t a scientist, he was a finance guy, but a creative one, and so unencumbered by geoengineering knowledge. He said, ‘why doesn’t low-enthalpy geothermal energy work?’ And I said, ‘because of the parasitic pump load that uses about 50-80% of the power produced, so little energy is produced’.
“He says, ‘well, to get around that, why don’t we just drill down two wells and connect them horizontally [below ground] and we’ll connect them on the surface and make this big loop — wouldn’t that flow better?’
“And I thought it was the dumbest idea I’d ever heard in my life… incredibly inefficient [and] capital intensive.”
But engineers such as Matt Toews, who is now the company’s chief technology officer, pointed that such a configuration would not only eliminate the parasitic pump load but would in fact pump itself due to the thermosiphon effect. This is because cold water is denser than warm water, so the cold essentially pushes the warm water towards the surface.
“And that got us excited… This is something where we can actually make a difference…
…This is the Holy Grail of power.”
As a completely closed-loop system, we circulate a benign working fluid that is isolated from the environment and therefore is scalable globally without fracking, GHG emissions, earthquake risks, water use, produced brine or solids or aquifer contamination. Eavor-Loop™ produces much-needed reliable baseload power.
An Eavor-Loop™ is the connection of two vertical wells with many horizontal multilateral wellbores creating a closed sealed radiator-like system. Eavor’s proprietary working fluid is not from a reservoir, it is selected and added at surface, then circulated to harvest heat from deep in the Earth to be used to generate electricity or in commercial heating/cooling applications.
A series of lateral legs stemming out from the vertical and cased well section after the 90° turn. Precise multilateral drilling is designed to specific subsurface profiles to maximize efficiency.
The profiled multilateral sections are completely separated from the rock and each other using Eavor’s protective Rock-Pipe™ completion technology. Working fluids are permanently isolated and contained within the system.
Magnetic Ranging Technology, a borrowing from the energy services sector, provides the basis to make these, at depth intersections consistent, efficient and safe.
The world’s most benign environmental impact & surface footprint. Eavor can fit in a backyard, repurpose inactive well sites or decommissioned industrial/commercial facilities. The facility has no emissions of any kind during operations.
The closed-loop system in an Eavor-Loop™ allows the fluid to circulate without a parasitic load, providing global scalability.
The Eavor-Loop™ system requires no connection to the outside world and operates without fuel and is completely emission-free. The fully-independent system can be placed in a bunker or buried below surface to be made resilient to natural disasters.
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 kilometres deep with many horizontal multilateral wellbores several kilometres 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.
The Eavor-Lite™ Demonstration Project is a full-scale prototype of the Eavor technology suite. The project site is located near Rocky Mountain House, Alberta. Drilling and construction began in August of 2019. Eavor-Lite™ consists of two vertical wells, joined by two multilateral legs at 2.4km depth, connected by a pipeline at surface. The rationale for this design, which is not intended to be commercially viable, is to build a project that proves and demonstrates all the critical elements of Eavor’s technologies at the lowest cost. This demonstration is designed to achieve the most efficient path to acceptance and commercialization of the technology by project developers and commercial financiers.
The Eavor-Lite™ Demonstration is designed to achieve the following three technical objectives:
