We've all seen Eavor on 2 different places now (Disruptive Investing) but who says oil money won't corrupt the mission? He said the wells had a 30 year lifespan but his graph showed peak power production ends in less than 2 years. Are we going to see constantly new drilling at the expense of ratepayers in the future? That's my worry, but hopefully other companies will get in, because this is really an open-source concept at this point.

As coal plants are decommissioned, their expensive and valuable grid connections will become available for re-purposing. Every old coal plant should be eyeing this technology so they can be reborn as a geothermal plant.

Problem is that this has more potential for environmental disasters. Cave-ins are a when, not an if, and given that, there's a potential for leaks of this geothermal water/steam to push pollutants from the mine into the surrounding water table. Another issue is the fact that coal mines release radon and other radionuclides. It's bad enough in coal country that state health depts have offered radon meters to affected towns. Overall it's promising in places that lack other renewable sources, but it needs to be engineered to fail safe and not spread any pollutants.

@@lozoft9 I think you are picking up on a different issue. The post was about decommissioning coal generation plants not coal mines. This was seen as attractive because the electricity grid infrastructure would already be in place at such locations.* The actual geothermal aspects would be deep down in unpolluted rock not in old mine workings. Also the system does not work at pressure so there is no mechanism for driving anything other than heat via natural circulation (according to this video). * Anyway, as far as the UK is concerned we already decommissioned 99% of coal generation so it's no longer an option.

Here in Sonoma County, we’ve been benefiting from 24/7 “conventional” geothermal power from The Geysers steam wells for decades. And we recharge the existing steam aquifer with tertiary treated wastewater pipelined from the central county treatment plant. Nevertheless, Sonoma Clean Power, our local power supplier, recently entered into contracts with Eavor, Chevron & Cyrq Energy to develop 3 new geothermal projects in Sonoma & Mendocino Counties. Cyrq is going to re-purpose existing depleted steam wells at The Geysers to create a geothermal storage “battery.” Eavor & Chevron will each be developing new Advanced Geothermal power plants strategically located to connect to the existing grid. It’s happening here!

In some areas this equilirium will be too low to use for power and the wells will have to be shut down, at least temporarily.

With newer drilling methods just around the corner (mm and plasma) they could go lower and get 500° C. At these temperatures existing power plants can shut down there boilers and switch to the geothermal source. The remainder of the infrastructure can still be used. While it is too early to know the exact cost of these systems, it will definitely be a fraction of nuclear. This will end any new nuclear.

Good Water Energy in Australia and currently expanding into the US, has patented mud percussion drilling technology that is now acheiving drilling costs below US$1,000 per metre into 400 degree granite and depths below 8,000m. The company has demonstrated continuous penetration rates above 15 metres per hour in 400 Mpa granite and bit life exceeding 400m. Gauge loss at just 4mm per 1,000m drilled in granite. Well completions are now possible at 11" below 10,000m with just $10m in total costs and below $9m when using on site geothermal elecricity to run drill rigs. Good Water Energy's patented drilling technology and the patented geothermal syphoning systems, geothermal green hydrogen, pumping, desalination and district heating patented technology is now making it possible to produce at any costal location, green electricity with a CAPEX below US$4m per MWe and generation coss below US$0.01c per kWh, sea water desaliantion at less than $0.10c per kl, green hydrogen production with alkaline electrolysis, below $1.00 per kg, urea fertiliser at less than 30c per kg (with a source of CO2) and district heating at a cost below 50c per MWt. To produce 1 million tonne of green hydrogen from sea water per year will require just 200Ha of land for a geothermal bore field comparred to more than 500,000 Ha for solar panels and battery storage. The deeper geothermal wells will produce on average, 20MWt from granite for hundreds of years without decline in production levels. Geothermal energy has the huge advantage of available thermal energy after elecricty generation to pump sea water, distill sea water and to compress hydrogen after electrolysis. These processes normally require more than 150kWh of elecricity per kg of green hydrogen production which is why geothermal enregy will be the only viable renewable energy source for commercially viable green hydrogen production, in any country. The sleeping giant is awakening.

S.Korea, geothermal plant caused medium scale earth quake and the closed after initial test. Few building and houses at Po-Hang, city near the plant, were damaged, some evacuated houses were never used again. Investigation reports water pumping changed tension of earth. it's really hard to prediction this kind of situation. It costed over $30 millions and the company bankrupt.

This idea must be tried and spread. Thank You for this information.

Another great video Dave, I am fully appreciating the gravity of the news that we are looking to be the first year where fossil fuel use decreased. Some great news in times of doom & gloom. Your videos are keeping me positive about the change happening around the world to hopefully pull us out of global catastrophe 🙏🏼

The report claiming that fossil fuel usage will decline in 2023 is a phenomenal spark of hope. Thank you so much for this Dave!

Having grown up in Alberta, Canada, where Eavor is based, I am very happy to see the advanced precision drilling tech developed in Alberta's oil industry used for this process. Eavor specialises in a closed loop system which has many advantages over tapping superheated ground water that is usually corrosive. Deep geothermal (10,000+ m) in granite could help mitigate the cooling effect of the water-carrying pipes in the hot rock. Alberta is addicted to oil and has a hubris problem. It will be difficult for it to transition to low carbon energy. But if they don't do it, especially with home grown industrial innovation, renewables and EVs will force them to pivot or risk owning a sunset industry with hundreds of billions in stranded assets and environmental liabilities.

I always wondered why something like this hasn’t been done earlier. Like 20 years ago. I mean we know how to drill right?!

I'm glad to hear about this company's progress. I remember seeing experimental deep drilling geothermal experiments back in the 1970s. This newer technology may finally lead to a practical expansion of those early efforts.

Awesome. Thank you for this one!

What is the lifetime cost/KWH? If it can beat other forms of generation without subsidies, it might be a winner. * It has a big advantage in that there is no fuel cost so it all comes down to construction and operational costs. * Operational costs should not be all that different from any other steam-driven system. * It seems like it comes down to the construction costs..... If the site does not require a huge investment in power lines to get to it, I would think it could end up being reasonably cost-effective. One interesting benefit is that the NIMBY problem would probably be a lot less than most other types of power plants.

Very interesting development. Is it really a "deploy anywhere" solution, or would somewhere with a lot of geological movement (earthquakes, maybe fracking) mean that the wellbores get damaged and can't function any more?

Well as long as you can generate electricity relatively nearby transmission lines can carry the power where it’s needed. I mean we already generate hydro electricity in BC and send it all the way down to the states, a span larger than most countries. But that’s a good point you have.

I wonder if there's an opportunity for district cooling as a companion to this tech. Use heat exchange to extract excess heat in the summer and use it to recharge the thermal gradient of an installation. (Maybe two installations, alternating which is active and which is being recharged.) Pumps and compressors required, to be sure, but the net still has to be better than most cooling solutions because the heat energy is captured for later use rather than dumped into the environment.

That depends. Heat pumps don't like high gradients and to actually dump heat down there you would have to heat it higher then the surrounding, so depending on depth over 300°. I don't think that can be done efficiently compared to just dumping it in the air.

Great show - thank you

This is excellent. A total game changer. I see only one problem (I've been in construction management with the USAF for 13 years and then at a veterans hospital in facilities management, construction inspection and designs for 21 years). What is that issue? Politics! I feel mentally hurt that we have a government that will demand the rare earth elements that only make us more dependent on China...making them more powerful and rich while we get buried. So that answer is getting on talk shows perhaps like FOX NEWS and podcasts and videos like this one. to force the issue into the light by public opinion and demonstrations... even picket line and poster like 'walkathons'. This should be an easy sell providing the nation buying into it is not corrupted!! So more publicity... get loud... do show and tell... give demonstrations to colleges and even High Schools as they (the young) are the future!

I would like to see an example of this geothermal technology installed adjacent to a major coal power station to use its existing boilers and electricity generating turbines. I would think this could substantially reduce coal usage, and lead to a total switch away from coal. The outcome from this example would provide a real world business case for converting climate polluting coal power stations into a heathier and a greener geothermal.

We keep forgetting that although the wind doesn't always blow and the sunshine isn't always there, the rise in battery storage is a perfect link to balance this deficit. And, as you say geothermal is a great asset too.😊

Geothermal has a smaller surface footprint that solar and wind, so should be easier to deal with local NIMBYism. If it uses fracking instead of Eavor's boreholes, then triggering earthquakes might be an issue.

Nice to see pretty views of Copenhagen! This technology could possibly solve a huge (from my point of view at least) problem with district heating. It is officially classed as carbon neutral, but actually burns trees from as far away as Canada. This is as far as I'm concerned neither carbon neutral nor sustainable, and yet the government and local councils are really pushing to roll out district heating to all.

Definetly feels like we have a large untapped continuous source of energy right beneath our feet! Its going to be interesting to see how we manage to extract more of this energy resource in future years

Thank you!

This is, as far as I know, the most promising technology to date to overcome climate problems. 👍

Geothermal is the only energy source completely independent from the sun.

As a Canadian I do share your optimism! 💪🇨🇦

Arguably the biggest benefit to this design that wasn't even mentioned here is that this tech doesn't rely on a massive increase in the quantity of metals and minerals required to make it work, the way solar and wind power do. Global mining capacity is not remotely close to meeting the demands of being majority wind/solar, but this geothermal tech could be scaled up with little to no mining increase because it doesn't need batteries or storage - no rare earths, no toxic manufacturing processes, etc. Fantastic.

I suspect the big vulnerability these systems will face is seismic activity. So, "anywhere in the world, regardless of geological conditions?" I doubt that statement in your description. But it does look very promising, and I have thought that geothermal was being overlooked and underutilized.

Areas of high seismic activity usually have heat sources much closer to the surface than other places. Which is why the Volcanic Ring of Fire around the Pacific aligns with where the earthquakes occur.

@@petergibson2318 True. But this specific design is around freeing us from the geographical constraints of those areas when trying to exploit the heat energy radiating up from the planet's core, and trying to get it someplace else. Looking specifically at the design graphic at 4:17 it seems that the various tubes would be very vulnerable to being severed or collapsed by even minor seismic activity. A few years ago while assessing risk of building on a specific piece of rural property in east Georgia, USA I looked at various things - flood, forest fires, hurricanes, drought, etc - and earthquakes were on the list. I was surprised to find how many small earthquakes were detected, and minor fault lines were mapped nearby (within a few hundred miles) of what I assumed was a completely stable area. It's not that I was wrong so much as that I just didn't have any real education in geology so I didn't think about how the crust beneath me is not one solid piece but many many different mineral composites and cavities filled with waters and gases that are actually constantly subject to forces we never think about pressing them together. So - I'm sure the engineers are aware of the risk. And the insurance companies will be too....

This is amazing. Looks to me the simplest and most easily scalable solution. I wonder if they are looking into a business model like say ARM where they make the basic design and let other companies build it for even faster scalling

Great walk-through of the process. It looks like a great design. Thanks for showing this progress to all of us 👍 😀

So great to see something with an optimistic tone after so much doom and gloom in the latest videos. Good luck with this project.

I was surprised that cold and hot pipes in Eavor's design were not co-axial. If one pipe was housed within the other pipe, and enough insulation was present, the majority of the heat would exist in the outer (hotter) pipe. Also, using heat density to move the fluid is excellent.

3:20 because they're not pipes - they're chemically sealed well bores. I expect this is a lot easier and cheaper to implement than trying to build actual pipes deep underground?

Overall, it sounds good. I do wonder if there are types of rock that will react in unexpected ways to being cooled by this process. I don't think it's likely to be a big problem, I'm just trying to brainstorm possible problems to watch out for before they happen.

I vaguely recall reading years ago about such a project in, I believe, Switzerland being shut down after it was believed to have caused tremors or minor earthquake.

In Finland geothermal heating has been a main source of heating for small to large scale housing. It is relatively cheap and subsidized by the state. There are a few s Flaws but in general it is a great system.

Vision: "Energy Reservation" solar panels or windturbines (both in some small areas) are installed on unuseable land. The intermittant source is connected to a baseload steam plant that runs off a geothermal, Molten Salt Reactor source with heat battery extension. (When there is sun/wind but no demand you melt salt to store heat for the baseload steam turbine). If a series of cluster bomb/ Tornado, Hurricane, 'quake takes out your stuff above ground you have the geothermal and reactor to keep things hobbling along. In a WIND reservation, build the kilometer high turbines that use atmospheric flow. That leave you space under them to run the methane bioreactors that process the sewer sludge into heating gas. As you go the mulch can go out to help farmers or stay on property to regenerate the land into a sustainable hardwood/ fruitwood/ fuelwood orchard forest under the windmills. In time you would have the ability to build high quality hardwood furniture and have a heat source stored up from the scraps which are pyrolyzed into syngas and charcoal. The syngas working to make steam for the electrical generation. The charcoal and leaked products would be environmentally friendly "Neutral" carbon and solids that the environment already handles from forest fires. (the charcoal could be either stockpiled or sold for various commercial/domestic uses. In a SOLAR reservation, build the vertical panel variety that is easy to maintain and plant rapeseed, soybean or other source for biodiesel processing sources. Then exploit those synergies much like above. Using conveyors to move the dry bulk is probably cheaper carbonwise than a fleet of trucks dashing about a bunch of non-consolidated facilities. I am waiting for the greenwash and virtue signalling to stop, and for someone with the deep pockets to develop one of these by buying up land on the leward side of a stripmine and rehabilitate the land. Something a coal mine might want to evolve into since it would be looking forward to the day coal generation just went away? Maybe convert that coal plant they feed into the ceothermal/biofuelled concept as they develop a Osage Orange forest on top of the old stripmine to fuel the plant on something carbon neutral, but almost as power dense as coal?

Thanks for another great video Dave. Sometimes fracking for oil can result in multiple subsequent small earthquakes, even in non-tectonic areas. I assume, from the description of Eavor’s process, that this wouldn’t happen with their technique. Is this true? Are their drilling sites low risk for earthquakes?

@JustHaveaThink

Жыл бұрын

They are not fracturing any rock at all. They are just drilling. So there should be no seismic implications.

@lorenkelley1568

Жыл бұрын

Yes, it is safe that way. The drilling that Eavor does just creates tubes in the rock. Fracking causes the rock surrounding the tubes to break up, which destabilizes the rock and can lead to small earthquakes. Fracking also produces a lot of waste fluid.

I am optimistic that scientists and engineers will save us from the unforeseen climate disaster. :)

Another advantage of this technology is that it remains an underground activity and thus won't aggravate the competition over ground surfaces, contrary to wind turbines or biofuel for example.

Great product!

This looks way better than a normal video call. Did you film both sides with a better camera while doing a video call, then just cut them together? I've been angry at other channels for not doing that because one side of the interview always looks so bad. Also, I'm thinking of 50 years in the future. One house in a neighborhood gets replaced with a plant that provides heat and/or electricity for the whole neighborhood. That would be my idea of an ideal decentralized energy grid. I wonder if these systems can be scaled down to that size, and not require a large footprint to install.

I agree about the high quality of the video call. It looks like a second camera was used, but they should have set it up so the the Eavor guy was looking into the camera. The side view was a little weird. I think there will be an ideal size for these advanced geothermal installations; neither too small nor too large in order to minimize the cost of the heat. Hard to say how big that would be, but neighborhood sounds a little too small.

This is very exciting! I'm so glad that I came across your channel, it's awesome!

I am very excited about geothermal, and I am increasingly confident that Eavor is moving in the right direction. Their well design reduces my concerns about aquifer contamination, induced seismicity, climate change vulnerability, and water consumption of other geothermal well designs. Our current alternate energy infrastructure does little to overcome the gaps in production of wind and solar energy. The power capacity and duration and the environmental impacts and cost of grid batteries (especially Li-ion) is driving us to find other ways to fulfill continuous base load and flexible power needs to integrate with wind and solar. I’m not saying that some use of batteries is not justified, but that lithium-ion batteries are not an adequate solution for scaling up the energy infrastructure for wind and solar integration. There are many grid battery designs based on different chemistries and technologies so I hope we move to those, but geothermal is, if we can prove the production, a far better solution.
