- How can we make geothermal energy part of the dialog, scale it and make it global? The man on a mission to change the world for the better by doing exactly that is John Redfern, one of the founders and CEO at Eavor Technologies Inc., a technology-based Energy company dedicated to creating a clean, reliable and affordable energy future on a global scale.
In The Switch special CERA Week episode we talked with John about Eavor’s revolutionary solution for scaling geothermal energy called Eavor-Loop™. This massive subsurface “radiator” that collects heat from the natural geothermal gradient of the Earth via conduction, represents the world’s first truly scalable form of clean dispatchable power.
Is this enough for creating the green grid of the future and can we finally convince people that geothermal is the ideal solution? Find out in this episode!

The concept is so simple. Maybe not easy but simple. I love it.
This technology should be the focus of renewable funding. It provides dispatchable power, with no supply chain weak points, while allowing nearly the entire existing oil industry to be redeployed with minimal retooling.
the issue i have with your comment is the "should" part. like.. to prove should.. im not saying issue like bad, but like good. how can it be from should to other word.. or how should the focus get there?.. thanks! n btw, it is my focus. like in my mind is a no brainer, but ive spend quite some time looking into it. (not much, like 6 months or so) best regards!
@@ivantijerinaf1207 I would say "should", at least in a Canadian contect, is demonstrated by a number of factors.
The long term phase out of oil, and the loss of a use for existing capital and manufacturing. Geothermal allows reusage of these assets, (drills, piping, pumps, etc) with only minor retrofit and retooling. Given the scale of the industry this is a huge strategic advantage.
At the same time, the geography that makes for good oil wells - generally former basins that have been filled with sediment - makes for good wind generation due to the expansive flat plains. This provideds a half solution for the energy transition, because these areas excel at low cost power, but generally lack hydro or other off peak sources. GoeThermal is an excellent peaking supply, as fluid temperature reached is proportional to the time the working fluid spends in the reservoir. During windy periods, lower GeoThermal demand allows the working fluid to increase above the regular temperature, and over produce when brought back online.
Finally, the oil sands offer an huge supply of high CO2 emissions at large point sources. This makes carbon capture relatively easy, if still expensive. Geothermal systems using Super Critical CO2 would allow a market for that captured CO2, where it would be sequestered in the systems reservoir, creating a carbon Negative energy source.
Overall a win win.
I would like to see policy that provides funding for half a dozen pilots, then allows those companies to bid on several projects worth 100 MW for power along side direct heat use (at industrial parks, or green houses). After that allow Geo to count as Storage when storage is being procured.
@@neolithictransitrevolution427 yeah, i get it. Maybe what weird me out is just the vernacular. Like "should" when i hear it, sometimes i go in my mind. "well you should go ---- n ----".. lol. But yes, the "g" is awesome to me. The id like i love, and stuff like that.. the details of the tecnology n the science is "well and dandy".
Wonderful interview. I love the crowdfunding idea
Technologies like this and nuclear make me optimistic about renewable energy in the future.
Seems very practical as a renewable technology.
Several years ago I read research papers that outlined tests by the US-Dept of Energy and also the US National Parks Service that used laser heated Tungsten drill heads that melted their way thru solid rock considerably faster than traditional rotary diamond head drilling. The added benefit was the technique left a sealed hard glass bore hole. Perhaps Eavor could evaluate whether this drilling process might be helpful at greater depths where traditional rotary heads have a more difficult time, precisely because the rock is hotter (and maybe the steel drill casing gets weaker due to the higher temps. This advantage over traditional drilling was cited by the research papers mentioned above.
Japanese company has a microwave 'ray gun' that is meant to liquefy the rocks 👀
Like how you put the term, making it scalable!
Basically, the earth has its own internal boiler…add piping and you’ve got a power plant. Faster, cheaper, deeper, cleaner….
& Free.
Heat pumps John definitely in our cold western Canada extremes that Phoenix,& New Mexico never know about!
I hope Elon Musk hears about this. A good use for the a Boring Company.
Boring Company boreholes would be orders of magnitude too large for this application. Boreholes sized for fracking are the correct size, and use a completely different technology.
These holes are drilled with more traditional equipment. But if this can be used to get energy on Mars I think it would get interest and funding from Musk.
Man I hope this works! If so, the way forward is obvious- wind, solar, geothermal plus storage - no need for nuclear
None of these options, while great for electricity, produce the heat needed for industry. Nuclear is the best answer to this (short of Iceland drilling directly into lava chambers) in a scalable way. Likewise nuclear shipping has existed for decadeds, but we have no electrified solution.
Either way will be great if they put their full force behind it. Nuclear would be far easier.
Geothermal has been used for process heat in a myriad of industries.
If deep frackers can do it, deep geothermal can do it. You don't need to compete with oil, gas wind or solar! you just need to compete with super expensive nuclear!
Sounds like the government could give some incentives for this potentially green energy production. Oh, but my God, would it lead to oil well drillers might make a buck. Come on, lets get it done.
Electrifying and heating an elaborate tourist trap might help to draw public attention to the cause.
The tragedy is the glacial slowness of geothermal energy exploitation. The obvious logic and advantages of Eavor projects should be accelerated to meet the increasing demands for affordable energy.
If Elon REALLY wanted to change the world for the better, he'd be funding this.
Shell, BP, and Exon already are funding this.
That's wonderful. It doesn't make up for their decades of climate denial efforts - not even close - but it's a very nice start.
John contact Saskatchewan Govt. investments, we've got it all next door, abandoned oil wells, old& or abandoned potash mines,a lot of start off drilling already out of the way& plenty of real estate to be developed!
If it the well heats the water above its boiling point, how doesn't the water on it's way down not turn to gas and force it's way back up the same way it came down as water before ever reaching the bottom ?
The force from the pressure of the injection well is greater than the convection of the steam.
The water on its way down (injection well) is colder and denser and heavier than the hot water coming up. The prototype Eavor has in Alberta has been circulating its water continuously for three years now with no pumping.
Not sure if will ease the guilt, but when you fly at 40,000ft, you are getting about 20 times the regular background radiation level, i.e. about 5 times the recommended maximum. As someone who flies a few times a year, I worry about it, but I fear for pilots and cabin crew, some of whom may not be aware of the amount of radiation they are exposing themselves to in their work.
It's very simple. Geothermal is the best way to decarbonize our electrical grids. Just as Biofuels are the best way to decarbonize our transportation fuels.
Biofuels are certainly not. You may not realize half the US agricultural industry is already producing soy oil for Biodiesel or corn for Ethonal. And still that is no where near energy sufficient. Between the associated nutrients run off, air emissions, land use, biodiversity loss, and soil loss, I would rather see us stick to fossil oil.
Of course, there are better options of changing zoning to allow more walkable cities, improving public transit to reduce fuel use and allow Electrification, Battery vehicles (or capacitor in the future), and Hydrogen.
But Geo + Wind is best for power I agree there. Although Nuclear is important too, if only for high temperature heat production.
It is unfortunate the interviewer was not technically inclined and too often mis-understood Mr. Redfern who did a very good job otherwise.
black swans can be good as well as bad. They are just unexpected.
i am like the kid that has a crush on your kid. (kid = Eavor startup). Specially because of its good looks (great visuals in the information content).. Also a cheerleader, and a hopefully good partner. I want to have many babies with your company. (hopefully i dont come across as creepy, if i do, i apologize, i watch a lot of comedy). ...well, thanks n best regards!
Drilling deep Mena’s low porosity and low permeability ! The heat conduction at depth is v low also.oil companies have people like me that know the truth . gT sucks
Ooohh, it that jealousy talking?
Would this technique work on Mars? If so you might get funding from Elon Musk.
She totally doesn’t get it… poor guy
Doesn’t work ! Rocks cool to quick. Nuke or nothing ! And the mugs were used to kill that in the 70’s
DOES WORK. Geothermal heat is generated by the earths core and moves into the rocks towards the earth's mantel so it is continuously renewing any loss of heat from cooling that is being done.
