How This Hole Keeps Generating Energy

In Australia we have this energy freely available in a town called Portland which is in Victoria but the authorities closed it down, it supplied thermal energy to the hospital and heated the local swimming pool.

[@cerealport2726]

as someone who has spent most of the last 18 years on oil rigs, as a geologist, and later an engineer, I can say that the process to drill deep geothermal wells is not really any different to conventional oil and gas drilling. We have the technology to drill very deeply already, we don't need this new plasma method that will use an incredible amount of electricity. Just because some technology exists, doesnt mean it's going to be affordable, or applicable. Geodynamics, a company in Australia already built a proof of concept for enhanced geothermal, or hot dry rock geothermal (look for Geodynamics Habanero project). They drilled multiple wells to only 4-5km deep, and circulated water between wells, generating steam, and electricity. One major economic hurdle was affordable corrosion control, not the technology to drill the wells. Conceptually, it's awesome, no need to burn fossil fuels, etc, but the reality is that there is no point building an amazing system if you cannot maintain the equipment and sell the end product at an affordable price.

[@beny9360]

Yeah. There’s some crap here hey… ‘attempts have been made to drill into the Earths core’.. Er.. no they haven’t. Touching the mantle would be hard enough. As you say, HTHP drilling is already done, but it’s not simple. There are many challenges and risks to it. I’ve drilled 120+ oil & gas wells. My mind boggles when anyone suggests drilling down to the upper mantle would be a simple affair even with any new tech. Note also that the Eden Project geothermal well referenced here has had drilling stopped because it caused felt seismicity locally - though geothermal is currently allowed to make around 3000x the seismic energy that was set by the U.K. regulators for shale gas etc. Either way, very deep drilling is no easy thing. As you say, it’s all about the economics.

You are right though, actual drilling time is only a relatively small proportion of time spent on well construction, with each extra unplanned trip eating up the budget.

[@ArchaeanDragon]

If I remember the Kola Superdeep Borehole history correctly, one of the main reasons they stopped it (beyond lacking money) was because at the depth they were at, the rock was almost like drilling through soft plastic. The drill didn't so much bite as "stir" the rock, and extraction of the drilled rock was made very difficult. That, and the well sides weren't very stable, collapsing around the drill head and string. They also kept having "mishaps" where sections of the drill string would break and they would have to abandon that current hole and start again above where the break occurred, probably due to the issues with the temperatures and the plasticity problems with the rocks at that depth.

[@cadekachelmeier7251]

If I remember correctly, the plasma drilling process claims to solve this. It's supposed to change the composition of the walls of the hole so it stays solid. Obviously it's impossible to know how it would work in practice until/unless there's a full sized demonstration, though.

[@effervescentrelief]

A huge issue is the shear weight of the equipment hanging in the hole and that drill bits use this pressure on the bit to push as they drill. Maybe the plasma drilling can solve that, but we will see.

[@deksroning125]

If I may, all oil and gas wells on Earth can actually be converted into Geothermal power plants for electricity and district heating/cooling. There are many abandoned oil/gas wells (including coal mines) that can be used for such a purpose... and oil rigs in the North sea are especially usable because the geothermal gradient there is far higher (aka, hotter temperatures at shallower depths of bore holes which automatically provide high enough temps for electricitiy and heating production [combined]). Additionally, A LOT of the said oil/gas wells already reach down 6 to 12 km... which are deep enough for electricity production. The Geothermal facility which was newly constructed in Cornwall UK was said it will produce about 3 MW of electricity and 12 MW of heating/cooling - and this is with a well of about 4.5km depth - which is not bad, but its also shallower than many oil/gas wells). It was also said that converting oil/gas wells to geothermal would cost HALF as much vs what it would cost to decomission them - and heck, why not? The infrastructure is already there. Plus, all of the equipment, people and their skills are DIRECTLY transferrable to Geothermal sector. While it is also accurate that for new geothermal power facilities the drilling costs are what account for 30-50% of the costs, what most people fail to realize is that utility scale geothermal power plants tend to pay for themselves in up to 10 years time (typically around 7 years maximum), after that, they are virtually free to run. They also have no running fuel costs, have reliability and efficiency ratios of 90-100%, and levelized cost of Geothermal has been holding steady for over a decade now at $70 per MWh (whereas most running costs of Geothermal are between $14-$36 per MWh). Essentially, Geothermal has all advantages of Nuclear, but none of its drawbacks (such as high running operational costs and production of nuclear waste - even new SMR's are ridiculously inefficient and will be producing 2-30 times more volume of nuclear waste than existing nuclear power plants - and their levelized costs are projected to rise exponentially in the coming decade - plus, standard operational costs of Nuclear are $156 per MWh - over DOUBLE of Geothermal). Also, when properly maintained, Geothermal power plants can last over 100 years (as is evidenced by the Geothermal facility in Italy/Larderrelo)... and Geothermal brines tend to contain vast quantities of Lithium and other mineral resources. It was said that the handful (about five or eight) of Geothermal plants in USA alone can provide the entire nation with many times more Lithium that it would ever know what to do with (and if we factor in other mineral resources in the brines, the payoff of the geothermal facility can be much faster than what I said above - similar ratios are for the Geothermal facility in Cornwall). So, technically speaking, there is no need to make new wells because we have a vast amount of unused oil/gas infrastructure (even used ones) which can already be converted to Geothermal for both electricity and heating/cooling purposes. But, I agree that Quaise' efforts at drilling 20km into the Earth would provide for much higher temperatures... but in that case, I would imagine that 20 km depth would provide for much higher temperatures than 400 degrees Celsius. At any rate, the biggest problem plaguing Geothermal are not higher costs of drilling or our ability to access Geothermal resources for sustainable electricity and heating/cooling... its BIGGEST problem is LACK OF FUNDING. Compared to any other energy source on Earth, Geothermal is the LEAST funded energy source on the planet. And when we factor in how much money is given in subsidies to fossil fuels... you can tell that governments and corporation priorities do NOT lie where they should be. Already, back in 2006, MIT released a study saying that we already had the technology at the time to access enough geothermal power to sustain Human civilisation for 200 years worth of... and that with improved technologies we can access enough Geothermal to sustain us for 2000 years. The oil and gas industry has been digging deep bore holes ranging from 6-12 km depth for 100 years now... its not an issue of accessing Geothermal... the issue is lack of funding and willingness to shift our attention to Geothermal.

Ultra deep geothermal drilling is more complex that your simplistic proposal. Lots of good comments in the replies explaining why it’s so difficult to drill and then maintain a HTHP well. Another area of deep concern is the trace elements and corrosive gases that at elevated temperatures create severe embrittlement issues. North Sea Central Graben HPHT gas field has not been fully developed because of this. As always cost and risk must be the overriding metric that justifies introducing ambitious new technology. Another area of this proposal that is way off the mark is borehole stability and pressure control. A vertical 12km well to ULTRA HPHT formations is probably too expensive, too risky and quite simply beyond the capacity of 99% of current drilling rigs and the people who run them.

in finland heating houses with ground heat energy is very common, usualy make 200-300m deep holes, take pipes down there with compressed alcohol, and the heated alcohol comes up to heat exhanger, it will take some electricity to compress and run the pumps, but its much cheaper then just to heat up houses with just electricity.

[@bersheck3076]

A problem you forget with geothermal energy is that you subtract heat from the rock and the rock is not a good thermal conductor. That means that a certain pipe has only a limited energy capacity until the rocks are cooled down enough so that the water will not be supercritical.

[@acmefixer1]

Exactly. And as he mentioned, it's very costly to drill a deep well. When the well runs out of heat and a new well must be drilled, did the amount of power generated pay for the first well to be drilled? Will the next well generate enough power to pay for its drilling? This also applies to the existing geothermal power plants that are located on hot spots in the earth's crust. The wells are much less deep than the wells that must be drilled where the heat is deep in the earth's crust. The drilling expenses must not exceed the returns from the power generated.

[@human_isomer]

Rock at this temperatures and pressures (at 10 km or below, provided the right spot is chosen) is not like the rock here on the surface. It's actually getting softer and even partly melts, a bit like thick, highly viscous magma with solid parts in it, having quite different thermal conductivity. And there are saline fluids which also can transport heat. Of course there is a limit, but with the right amount of water pumped in, there will be little issues with keeping it hot. But there are other issues. In case a non water-permeable layer of clay is penetrated, and water spreads into formerly dry layers below (e.g., into Anhydrite), those may swell, raising the land above quite a bit. This already happened, and it literally ruined villages. Such issues are hard to predict, because of the actually unknown structure details and porosity of the rock below. Another issue is liberating toxic substances from under ground that were kept there before, e.g. heavy metals or radioactive material. And in case of a movement of the (softer) rock below, the pipes may easily get crushed, posing another issue. We actually don't know very much detail about the earth's mantle, as it is hard to just go and have a look. Thus it is difficult to chose the right spot to drill.

[@acmefixer1]

@@human_isomer I believe they line the borehole with a pipe down to below the depth where there are no more layers for water to go into. The water is under pressure so it seems possible that some may leak between the pipe and borehole.

[@cerealport2726]

You underestimate the available heat. You also fail to consider that multiple wells would be needed, either as stand-alone systems, or as a system of interconnected wells, circulating water with additives. It has been done already, and if the well spacing is good, then you get enough heat generating to run a power plant for decades before needing to introduce new wells.

[@cerealport2726]

@@human_isomer You absolutely do not need rock that hot. You need it to be 200-300 degrees (celsius) or so, enough to turn water into steam.

[@cerealport2726]

Conventional wells are drilled using a fluid (drilling fluid, or 'mud') that has its density controlled to it keep the wellbore from collapsing. this also provides the medium to carry the rock out of the well, and to cool and lubricate the drill bit, as well as providing some hydraulic force to assist the bit in breaking rock. Drilling with plasma at any depth will be challenging because they will have to somehow support the borehole and stop it collapsing. Building up a vitreous layer on the wellbore will not provide much in the way of wellbore integrity, and it wont use all of the rock that's drilled to do it either, so there will need to be a mechanism to remove the rock. On top of that, electronics suitable for harsh environment, such as very hot wells do exist, but are extremely expensive, and do not have a long life. As a drilling engineer, I'm all for new technology to drill faster, and cheaper, while still staying safe, be it for oil and gas, or geothermal, but I am not sure this particular technology will do the job for the same price that we can do it now - and right now, we do have the technology to drill into rocks of the required temperature and pressure to maintain water at supercritical conditions.

Having worked in the Oil and Gas Industry and a bit with waveguides, I'm wondering what the losses on kilometers-long megawatt scale waveguide might be? Also, Microwaves powerful to blast through hard rock at meters per hour could do the same to a wave guide as well, and even if waveguide losses were minimal, over miles could add up and over months of operation could degrade the wave guide surface through: Conductor Losses: The conducting walls of the waveguide can lead to power losses due to the finite conductivity of the material. This results in the conversion of electromagnetic energy into heat as it propagates through the waveguide. Dielectric Losses: Dielectric materials such as insulators or fillers in the waveguide can absorb electromagnetic energy and convert it into heat. This absorption is characterized by the dielectric loss tangent, which quantifies the lossiness of the material. Radiation Losses: Imperfections in the waveguide, such as bends, joints, or gaps, can cause some of the energy to be radiated away from the waveguide, leading to power losses. Surface Roughness Losses: Irregularities or roughness on the inner surface of the waveguide can cause scattering of the electromagnetic waves, leading to additional power losses. Mode Conversion Losses: In multimode waveguides, energy can be lost during mode conversion processes, where energy is transferred from one mode to another. This can occur at irregularities or transitions within the waveguide. Aperture Losses: In waveguides with apertures, such as horn antennas, there can be losses associated with the transition of energy from the waveguide to free space. Absorption by Gases: If the waveguide contains gases, such as air or other contaminants, these gases can absorb electromagnetic energy and cause power losses. Skin Effect: At high frequencies, electromagnetic waves tend to propagate near the surface of the conductor. This skin effect can lead to increased power losses in high-frequency waveguides.

As much as I appreciate the effort made in this video and as much as I like geothermal energy, there is just so much wrong in this video. Redoing some of the voiceovers and cleaning up the misunderstandings may get the video to standard. First, and foremost, there seems to be a fundamental misunderstanding about the structure of the Earth and the composition of its different layers. I get the feeling that everything below the crust(?) or below 15 km (?) depth is referred to as the Earth's core? Secondly, the core is largely iron and nickel, which means there is essentially no significant radiogenic heat produced in the core. The radiogenic heat is rather produced in the mantle and crust. Thirdly, the super deep drills at the Kola peninsular and in Germany never were motivated by exploring geothermal heat. These were scientific projects. Also, what is the Earth's impermeable cap rock? If it is impermeable, how do they drill there? Lastly, the normal geothermal gradient is estimated at something like 25-30 C per kilometre depth. This delineates some of the problems with deep drills, as you drill down you experience very high temperatures and pressures. The temperatures will compromise your drill, whereas the pressure will constantly try to close your drill hole. At 4:20 minutes in you say: "Attempts have been made to dig very deep into the Earth's core." No. The outer core is about 2900 km down and more than 3000 C hot. At the Kola Superdeep Borehole, they drilled just over 12 km ... you may find that there is still some meters left from 12 to 2900 km depth. At Kola, it was also somewhat hotter than expected (180 C) at 12 km depth, which was the problem that ended the drilling. Kola was chosen because back in the days the geothermal gradient below the Baltic shield was not well understood and they expected only 100C in 12 km depth. Then again, 180 C is not that much, you would think-water is supercritical at 373 C or so. Heat exchangers are needed to get water supercritical. So this business wants to drill 20 km (~500 C). OK. Not the core, though... still far from the mantle even, which is at about 660 km, even the lithosphere goes done to ~120 km. Do they have a plan for how they keep the hole open at extreme pressures and how to deal with the heat problem? The middle crust and the ductile-brittle transition is about at 15(-20) km depth, that is where rocks start to behave plastic over geological times...that is how hot it is down there. Just saying...

@@freemind.. Who says lava can't be radioactive? But part of the reason could be that lava in its magma state is hot enough that it can disperse radioactive matter, spreading out amongst the liquid, and potentially decaying faster due to interactions with other materials in the magma. Where a hot solid rock is just going to sit there, so concentrations of radioactive materials would be more likely.

The problem is that you cannot extract energy from anything without side effects. Energy may be large on a global scale, but local extraction of heat must have an impact on local geology. If you are taking heat from local rocks then that local rock is cooling, and what impact will that have in terms of what is happening to the material above the above the rock. Could you cause local earthquakes as the rock cools and gets denser allowing the rocks above to collapse down?

[@peoplez129]

Geothermal is one of the worst energy types possible. The earth absolutely needs its heat, because it's never going to get hotter, it's always going to get colder. All that heat is left over from earth's formation. Without it we not only weaken the magnetosphere, we also would eventually change the earths rotation/tilt. It's not so bad in small cases, but if humanity came to rely on it and started extracting the energy in large amounts, it could pretty much doom humanity and all life on earth itself. One might say "Well we will stop if it seems to be causing harm". But firstly, the harm would be completely irreversible. You can't put heat back into the earth. Secondly, with us being soo hooked on it and already having all the infrastructure in place, people would not stop using it. Especially when we're talking in a future where people need energy more than ever, and billions of thirdworlders using increased energy as their lives modernize.

This is because it interrupts and mixes colder and warmer layers of the atmosphere.

I have to object to the usage of “infinite” in the title. The amount of energy stored inside the Earth might seem like a lot on human scales, but it’s still nowhere on the scale of infinite. And even as a practical matter, if technology and the population continues to grow, we could conceivably burn through all that energy in a pretty short period of time, geologically speaking.

I cringed every time you referred to the Earth's core. No hole has ever gotten remotely close to it. I don't think they've even gotten into the mantle. Various drilling projects have gotten very deep into the crust, but that's it. The earth is 6317 km in radius, the Kola Superdeep borehole is "only" 12 km deep. There are projects with the aim of drilling where the crust is at its thinnest, but I can't find any information about successes even there. One problem is that these places also happen to be in the ocean, after all. I still think nuclear is the best option for base load power. One objection I've heard is that the plant plus the exclusion zone around it could be better filled with a solar and/or wind farm. Why not do both? A nuclear plant in the middle with an exclusion zone filled with renewable generators. The best of both worlds with nuclear providing a stable base load and the renewables satisfying power for peak periods.

It's not hard to imagine drilling a deep hole, but it is hard to imagine creating a reservoir underground artificially.

The manhole covered hole in russia is already deep enough for geothermal energy, the rock around the bore-hole was said to have the consistency of plasticine more than solid rock, and rock at those temperatures are more than sufficient for people to put a thermo-coupling into the middle of it and run a couple of heat exchangers to keep from fracking the mantle and causing an earthquake like conventional "geothermal" systems attempt to do, making the water use the entire rock structure without ensuring there are no contaminants and deep faults that can cause an earthquake or a sinkhole with erosion over time. The key to designing new geothermal systems is to make the borehead the actual heat extractor and use it to create steam power for a steam powered turbine at the very simplest.

[@jamesball7381]

It is worth noting that there is not a net production of geothermal energy from the decay of radioisotopes in the current day. The heat flux from the Earths surface is greater tham the thermal energy produced by decay of all long lived radionuclides (e.g. U-238, U-235, 147Sm). Most of the Earths thermal energy was generated in the first 10 million years after the Solar System formed by the fast decay of short lived radionuclides (mainly Al-26, Mn-26, and some others such as 92Nb, 97Tc). This was a ubiquitous process in the early Solar System and provided the heat that produced some of the oldest differentiated meteorites (iron meteorites). Some of the heat was also provided by the accretion process amd the latent heat of crystallisatiom during silicate differentation, again both very early processes that occured before 60 million years after the Solar System formed. The large radius of the Earth has insulated this heat for 4.567 billion years. But the Earths geothermal energy has been slowly lost to space for most of that time and is still being lost today.

Once you get deep enough, you really do have near limitless potential.

No doubt that the earths core is heated by radioactive decay (which is why the earth's volume is about 8x more than when the continents first formed), as well as electric currents (charges coming off the sun, spiralling in at one pole, flowing through the earth, and returning through the other pole)

This approach has two major challenges. First, you don't just have to make the hole, you also have to get the material OUT of the hole. And even if your drill bit doesn't care about the temperature of the rock, the pipe bringing the rubble up certainly does. Second, you can't drill deep just anywhere. There are pretty specific limitations on where you can drill, so many power plants will just not be in a good physical location to start drilling. It isn't even about the depth. Soil and rock type, presence of sand or aquifers, etc can all interfere with drilling operations even at shallow depths.

[@TheBasicTruth]

The now age-old problem with getting free heat energy from geothermal sources is simply to do with the poor heat conduction of earth-rock. Any heat energy removed from a location under earth's surface will cool that location, and it takes time for that heat to be restored from beneath the location. No matter how large the area chosen beneath the crust, cooling will happen, and restoration of that heat occurs at a fixed rate. The rate of extraction of that heat can be calculated, and it is usually too low to provide all that is needed above ground. Wairakae Power Station is a geothermal plant in central North island New Zealand. It has been dogged with this cooling phenomenon since it was built in the mid-twentieth century. The surrounding rock under the earth's crust at that locality has been cooling from the start, thus limiting the rate of extraction of heat energy to much lower than when the station was first built in the late 1950s.

This once again has already been tried several times. The problem being the deeper the bore hole - the prone to failure of snapping the drill stem. And as you get closer to softer rock it is more like plastic and you can't drill it. It is to pliable. Yes these ideas all sound wonderful. The Russians tried with the deepest bore hole and could not get past the soft rock layer. It's been tried by SANTOS in outback Australia - and the drill equipment kept failing due to bore depths. And the temperatures really were not getting to the levels to generate steam. Again all these "wonderful" wants someone else's money to waste.
