To Anna and Christopher. From an engineering point of view, you are doing an amazing job. I also think your heart is in the right place, genuinely looking for a clean alternative solution. - Kudos for that. My fear is that in the long run, you will be thrown under the bus by people whose goal is not a better solution for the people but a better solution for their personal profit and power.

[@justajo2]

I can see it now. The 'green' extremists wanting to shut down the drilling because it is bad for the environment just as they believe fracking is. I'm sure they will try it even though there is no fracking here. The only Eavor borrows from the oil industry is the deep drilling tech. Even then, they are developing some of their own unique technology. Go for it kids! (I call them kids because I'm 77 years old.)

Yes, but they’ll still have to be price competitive with PV + battery, which is getting cheaper all of the time.

[@incognitotorpedo42]

Not everything is about price. The low cost of Solar is irrelevant at night. LCOE of geothermal has to be taken into account along with the LCOE of sun and wind energy production because these systems work in tandem. No?

[@williamlloyd3769]

Stationed at Naval Air Station (NAS) Keflavik in 1979-80. The geothermal power plant extracted hot brine water and used heat exchangers to heat the fluid that flashed to steam to run turbines that produced electricity. Additionally the fluid was used to heat water for the heating district. So the NATO base got electricity and hot water to heat all the buildings. Finally, the plant dumped excess brine water into the lava field. That waste water was the origin of the Blue Lagoon which back then was an undeveloped pond with some stairs so that you could get in and out without slicing your feet up. PS - Hopefully, if there is an eruption, the new lava flow won’t destroy the plant!

The science was so new that we were the first, Government funded and built, full scale base load generation plant in the world. To see the fields today is fascinating, the hundreds of kilometers of pipes cover many square km of farmland. I would love to see this new tech in other parts of less Geothermal activity, here in NZ.

I've been following Eavor for a couple years. IMO, they need to adopt plasma drilling technology which is hopefully coming on-line soon. This will significantly reduce the cost of drilling to even greater depths than Eavor is currently doing and make their energy production truly the lowest LCOE (levelized cost of energy). Hope that Europe can adopt this technology as fast as possible so that Putin can be made redundant and everyone can enjoy clearer air at the same time. Exciting times.

Agree re the European situation. In the UK we have the Government suggesting fracking as a solution to Putin. This would be a great fast fix.

[@jackcoats4146]

Some years ago I worked in the 'oil patch'. I must agree the ability to drill precisely was amazing back then, and today I only assume it is more so. ... On of my employers was Amoco, before purchased by BP, in exploration 20Million was a typical exploration well, so 100Million is not that much money considering they put billions into exploration annually. When I was working the Exploration would find a revisor, guess as to its size then sell it to the 'production' company that would put in many well in a field and operate and produce it for many years. Eventually most fields get sold to secondary production companies (smaller oil companies).. Oh the production company typically sells the oil to their own or others refineries who the sell the refined products to wholesalers or retailers. Every step along the way each company was normally required to make their own 'profit', so the true level of profit in these companies was often obfuscated, IMHO.

[@paulgracey4697]

Thermosiphons are old technology. The Model T Ford used that method to cool its engine with no water pump at all. The radiator does have forced air from the engine through its fan, and the temperature difference alone is sufficient to cause the water to circulate. Look at old trucks and other cars from that era and you will see the radiator is mounted quite high compared to cars with water pumps. Cars from my childhood also tended to have thermosiphon effects even when there was a water pump. Like the hole in the bumper under the radiator for a crank to start the car if the electric starter failed, cars were made with redundancy to continue working back then. Today if the computer dies so does the modern car.

[@jonwelch564]

A Model T probably couldn't produce much heat, so a heat syphon might have been sufficientl. Old cars used to boil over when I was a kid, I don't have that kind of a problem now days. My work van has just had it's first problem at 87,000 miles, the exhaust injector has just failed causing it to go into limp mode (not a real issue, but Ford want you to get it fixed). Old cars cant compete because modern technology beats it hands down.

Great vid, info & commentary guys, ever since I first heard of this type of tech some years ago now, I believe this could be a real game changer for scalable, renewable power generation. Im surprised there hasn’t been more hype & $ thrown at it. I think the location issues may well fade with better, deeper drilling tech in time. Here in Australia I am sure we have many potentially great locations for Geothermal Power generation, the proof is where we have hot mud springs coming to the surface and Artesian wells/bores drilled all over the place with hot water bore drains running for kms, I believe we have capped most of them for now. There is more heat source power below us than we can use, id be very happy to see governments throw money at this tech, its probly one of our greenest solutions.

Love the concept. The question I would have pursued would have been their ability to overcome the heat degradation on the drilling equipment. I believe that has been the limiting factor on how deep we can drill Is it breakthroughs in material science that will allow them to overcome that.

[@kevinstone7723]

Standard drilling equipment like the drill bit and the pipe used to rotate it can handle temperatures (1600+ degrees F) way above what their target temps are. When you start getting into directional drilling tools, downhole motors to spin the bit without spinning the pipe, and their tools used to intersect the two boreholes, those are the items that really don't have very high temperature ratings due to the moving parts, electronics, and rubber seals (probably 300 to 400 degrees F or 150 to 200 degrees C). Any technology they have for hotter temps than those they will have to develop if they haven't already. Mostly that means developing non-rubber seals and making sure the materials used in tight tolerance applications have similar coefficients of thermal expansion. Also developing electronics that are either non-silicon based or are encased in some type of dewar flask style insulation.

[@trey2076]

As the depth of wells being drilled increases, the weight of the drilling mud must be progressively increased in order to prevent the open section of borehole from collapsing and to provide sufficient hydrostatic pressure to prevent the well from kicking or blowing out. Strings of casing are also run as needed to eliminate problems with shallower sections of the borehole.

It is a misunderstanding that in Iceland all geothermal power stations use areas were the hot water or steam reaches the surface. The bigger geothermal stations use boreholes around 3 km deep to find steam. Places were you find hot water at 3 to 5 km without any sign on the surface, are rather more common than expected. Icelandic have done work in other countries finding those places and exploit them. Iceland has also done a bit of work on binary power stations. You can run binary cycle down to about 80°C. Geothermal is really underutilized, especially at it can be used as base power 24/7/365. There is also possible to use fracking technology where you have hot dry rock. You drill holes and frack the rock, you pump down water in one hole and get steam up in the other hole.

After a well has been drilled, open-hole wireline logs are run to identify productive formations. These logs accurately indicate the borehole caliper, minerals, porosity and types of fluid present in each formation. Another wireline tool can then be run to measure the permeability and retrieve samples of the fluid. In productive intervals with low permeability and containing high viscosity fluids, downhole reamers are often used to enlarge the original borehole. Doing this increases the productive capability of an interval and minimizes production damage to the borehole. These reamers have extendable arms lined with PDC cutters that fold downward along the sides of the tool. It is placed in the BHA (bottom hole assembly) and is designed to pass through the previously drilled borehole. When it reaches the desired reaming depth, mud pumps provide the hydraulic pressure necessary to force these arms outward and make contact with the borehole while the drill string is being rotated and moved up and down. This procedure continues until a larger borehole has been created in each zone of interest. The arms on these reamers are pulled back onto the tool when the pump pressure drops, thus allowing it to be moved to ream another interval or brought back out. Centralizers are attached to casing as it is being run down the well to assure the casing will be held away from the borehole in the areas that will be cemented. This is to assure cement will be able to bond with the casing in order to seal the annulus of the well. A cement float shoe and sometimes float collars are placed in the string of casing as it is being run in order to control where cement will be pumped into the annulus of the well. After all of the casing has been run, a calculated amount of a customized cement blend is pumped down the casing, followed by a measured amount of water sufficient to displace it in the casing, thus forcing the cement into the annulus of the well. The string of casing is hung from the derrick of the drilling rig and isn’t moved until the cement has harden, and then a wireline bond log is run to confirm it has bonded with the casing. If not, then a cement squeeze may be necessary to assure the well has been completely sealed between the borehole and casing. This is extremely important to protect fresh water aquafers. Many times cement is pumped over a productive zone and later perforation guns fire multiple holes through the casing and cement into the formation. When a productive zone is near the bottom of the well, the casing is often run 30 to 40 feet past the porosity in order to provide room to easily complete the well, then cement is pumped through a cement float collar located above the productive zone so that it won’t be covered by cement. Drilling mud prevents cement from going very far past the float collar, instead it is forced to flow up the annulus of the well. The drilling mud will then be removed during the completion work, therefore enabling production to be optimized.

[@jeffbybee5207]

@@jonwelch564 if casing is placed in all sections of the drilled area and somehow sealed to the main up and down pipes then heat can be collected with out fluid loss or contamination but the casing it's self would slow heat transfer.

8:14 and following - I think Anna did not quite understand Zac's question, but it was inadvertently answered later by Jesse at 14:30 - that is, it was known that there was this heat underground but in most places it was not enough to simply harness steam and run a turbine - and whereas there were already good enough ways of producing energy from the oil no one bothered to look much further for other options. The innovation is in transferring the heat from the hot water to another liquid and using the gaseous form of that other liquid with a lower boiling point to turn the turbine in a closed loop.

[@alanlight7740]

Can you repurpose existing wells?

[@karlstone6011]

There's hope!

[@berringtonfox5628]

Very interesting... what are the initial costs?

[@ehombane]

they mentioned the price for the pilot, I mean the first funding, and since they done only that pilot, that is the price of the pilot. Sure, research implies other costs too, but still the cost for a full scale plant will go into billions. And return will be in decades. Why do you think that it was not done till now? At least in areas where the heat is closer. Actually there is other startup drilling in UK where the heat is closer. But they are aiming at a fracture to use it as radiator. So is a combination of closed and open. I wonder at what stage are they now. I learned about them few year back.

What about using the sand batteries to store heat in summer when less required? What was their name again???

[@jonwelch564]

Listen again 21:55, they can match grid demand. You just open or close the tap to control the energy output. No point in storing heat else where when it just sitting there under ground.

Super coool 🌞😁😇

an other good reason to test this in Germany is that Germany is midtier geologic active. So it is hard enough to get to the heat that innovation is necessary. But within those regions that don't really do Geothermal because it is to hard it is one of the easiest. Therefore that Region seams to me to be a good testing ground.
