No. Actually this is quite similar planet killing as it was in those good days when the guys were drilling for gas. Let's use heat that we already have in our atmosphere and planet surface - better not to release much more from inside of our planet.

You would think that every new housing development could share one reasonably sized bore hole for District heating. That with a solar array and GSHP and maybe a battery and every house could be essentially carbon neutral?

[@klaxoncow]

And, in addition to carbon neutrality, there's the economic win of no-one ever having to pay a heating bill ever again. My mate moved into a flat in a new apartment building in our town. It had been properly built with all the insulation, solar on the roof of the building that powers an air source heat pump. No-one in the building ever had to pay for heating. Completely free and included. It can be done because, in places, it is being done. And my mate's chief complaint was that, actually, it was too hot. Whatever insulation they used was, arguably, too good. As his problem was always trying to get rid of the heat, never once that it was never warm enough. Note: If you're ever getting a heat exchanger / heat pump make sure that it's reversible. Because, yes, any heat pump / heat exchanger can be rigged up to run in reverse and actually take heat away, and act as air conditioning. And, trust me, you'll want this. It might not strike you as likely, if you're struggling to warm up an old Victorian house in Winter, with high energy bills, that your problem would ever be the opposite - that you're getting more heat than you ever wanted for no cost whatsoever. But, seriously, that's what my mate experienced in a properly constructed modern apartment block, as they'd built it from the ground up with the best insulation and using a solar-powered heat pump (air source rather than ground source, admittedly - but that's the thing, air source is possible anywhere, where ground source might not be easily done). Imagine the economic win of every building in the entire country having free heating. Well, the energy companies would lose out. But, like, the largest part of most people's electricity bills gone in a puff of smoke. Hundreds to thousands of pounds a year put back into everyone's pockets again. Free money for everyone, basically. The technology's already there. Because, as I said, I've seen it in action. A rather large apartment block (there was at least 50 generously-sized flats in the place) where no-one paid for heating - all inclusive - and, truth is, it was too good. The residents complaining that they needed to turn off the heating more often, as it got too hot and never the reverse. And this is without going on to consider ideas like district heating and distribution. So, if that apartment block got too hot, then it could pump the excess heat out to other buildings. And battery storage to do the same thing with any excess solar. My battery's full so, here, have my excess. Put it on the Grid, for someone else to use. We could eliminate anyone ever having to pay for heating ever again. And that is, by the figures, the biggest chunk of what we pay for, that creates the most carbon emissions to satisfy.

[@s4098429]

Planning permissions would be a nightmare. They all ready are for aesthetic reasons, but it would increase 100 fold, ostensibly for ‘environmental’ reasons.

I think baseload will always make sense to some extent. If something is constantly using power, why create energy, transfer it to battery, then transfer it to the constant power use. I think it makes sense to get a baseload that handles the constant power use and then even separate it from the grid. Battery storage works best flattening out a peaky usage and/or supply.

[@davefroman4700]

@@trevorWilkinson Our current arrangement is inefficient because it does not have storage. You only need 4-5 hours of storage in any grid to displace 80% of the generational assets. And we receive more energy from the sun in a single hour on this planet than our civilization uses from all other sources combined. Including fossil fuels, each year. Its a stupidly small fraction of a percentage that we need to capture and store to meet our daily needs. The current grid needs base load because it is a centralized system. The new grid infrastructure is distributed with millions of contributors. Solar and wind are distributed energies. In the next ten years we are going to hit what is known as "God Parity". That is the point where it is cheaper for the consumer of power to be energy self sufficient, than what it costs the utilities to deliver the power, before the marginal costs of generation are added to the bill. We are already way past grid parity today.

[@staudtj1]

If there are no inter-connecting pipes or the pump in pressure is high .... it's Fracking. What is the working fluid? Is it fresh water? How much water? Is the water recycled?. How much energy do all the pumps use? 4 or 5 megawatt can be done with one semi-large wind turbine. Tons of questions here about costs and long term heat availability in the area being worked.

[@timj11dude]

Was wondering if this would have the same issues as fracking. Would like to see that question answered, otherwise would love to see more geothermal plants all over!

[@trevorWilkinson]

@@timj11dude They mentioned that it doesn't use high-pressure water so it is not trying to break and crack open spaces underground. Think of it like water cooling the earth. There is a water which is passed through a loop which gets heated, the longer that water spends down there in the fissures the more heat the water can absorb. Before returning to the surface where we extract the heat and the loops starts again using the same water/fluid. The most damage is done by the drilling itself. It might not create the most energy and they did say it was a bit of a test project. They could probably get more power by having a bigger gradient between the hot entry and the exit. Perhaps also by drilling deeper and also my increasing flow rate of the water/fluid. But as they mentioned it's not to compete with wind or solar, it's to work along-side and be a base-line which won't fluctuate depending on the weather.

[@mralistair737]

frackin is using pressure to fracture the rock, they are not trying to fracture the rock, they are using existing fractures, the liquid going in (presumably water) will very likely be at a similar pressure to what's down there, the main pumping pressure will likely be generated by the water heating/boiling. it's probably / possibel that its a closed loop and that what comes up goes back down, and it just goes through a heat exchanger at the top.

@@ferkeap a liquid that is hot and under pressure, then released to generate movement and cool. is the reverse of one that takes low pressure cold gas and through movement turns it into hot high-pressure liquid.

it will be a gamechanger when plasma drilling works worldwide

[@paulm3538]

As mentioned in the video, it’s the oil and gas industry that has provided all the technology to be able to drill geothermal wells - not just here in the UK, but worldwide. For commercial geothermal power production, you need to pump water down the deep well and then back to the surface through the shallow well once it’s been heated. There will inevitably be some seismic response due to the higher underground pore pressure from pumping water underground. The pressures are not as high as those used in ‘fracking’, but will be seismically detectable. By default, you have to accept that seismic response if you want to utilise geothermal commercial power.

[@CornishMotorcycleDiaries]

That was covered in another video. There is a drilling site at United Downs near St Day in Cornwall.

[@LudvigIndestrucable]

The energy generation is obviously great, but the provision of community heating is the only way to fully realise the benefits of such installation. From fossil fuel plant burn to plug, you lose about 80% of the energy, with a significant amount of UK homes actually heated by gas.

[@NickAskew]

I guess if they are not fracking it means that they are relying on the fault being porous enough. They won't know that for certain until they get to depth. However this is a great repurposing of the drilling industry that I am in and a truly exciting step in the right direction.

Geothermal heat is generated from decaying uranium and other radioactive isotopes in the earth’s core. As long as enough wells are drilled deep enough the heat is always there.

[@goone7264]

Is this durable, or will it deplete the source as well? I believe the core heat is a part of the magnetic system that protects the earth from gamma radiation. One system would'n't mind, but on a global scale it is frightning. Is this the new race for drilling energy? Any thoughts?

[@Rhine0Cowboy]

I would have liked it if they addressed whether or not the heat sources in these wells will fade over time. You'd think they'd at least reach some kind of equilibrium that's at a (possibly substantially) lower temperature compared to when you just started exploiting it.

The Earth is an extremely large natural nuclear fission reactor, there is enough nuclear material(fuel) for plus 1 million years.

[@Rhine0Cowboy]

@@michael-vl1mn That heat is produced much further down though, once the local heat has soaked out of the area you drilled, it will usually only warm up again at a relatively slow pace that might not match with commercial exploitation.

I love Robert's enthusiasm, but I am unpersuaded. On average heat flow from the centre of the Earth across the UK Is 0.038 watts per square metre. On average (night and day) average solar power is about 240 watts per square metre. So to extract heat sustainably one needs to extract heat from a VERY large area of rock. Otherwise one simply cools down the rock over a few years. This may make sense, I don't know all the numbers, but this video makes me think that solar power with big batteries is probably a better bet at the moment. But good luck to them.

YES. Get Big Oil to drill for HEAT

[@blueslsd]

It's just so so obvious now! Great video.

[@Charli3Brav0]

Well developed industry 😂👏 Exciting stuff, great to see it also offers an application for all the kit and personnel soon to be looking for work

[@nicevideomancanada]

No not decaying radioactivity from the centre of the earth, but instead from the Granite it's self.

Several decades ago, I recall reading about Californian geothermal operations having a problem with their pipes and equipment getting clogged up from the dissolved minerals. It sure sounds like the water in the kind of loop described here is heading for the same kind of problems, becoming increasingly laden with various minerals..

[@ALFAAZ-E-KALAM]

Now that's called informative video about one of the renewable energy sources other than solar and wind. Whole year videos just about EVs & EVs was making it lil boring but such videos I like to watch. Lithium extraction was great video too. Now I want to see a video about technical updates in PAVEGEN & is it possible to increase it's output to MWs :). Keep it up.

[@davidkendall2272]

Fascinating discussion. Great topic. Thanks

[@tonystanley5337]

baseload is "load" not generation. You have generation for baseload, but baseload is an diminishing load type as load becomes more efficient. What geothermal is, is firm power (in theory), the problem is it is very expensive compared with renewables. Ultimately geothermal has the same problem as Nuclear, in the firm power can be a noose rather than a solution when you try to supply variable demand with it. Like intermittent renewables it needs storage or interconnects when demand is lower than supply.

[@shumie4]

What are the chemicals used in geothermal systems ? Antifreeze is used in the circulation pipes. The pipes also leak into the groundwater.

[@ferkeap]

Water and sludge, grease for the drill shafts.

[@kieransymons1134]

Are we just going to ignore the fact that Geothermal engineering in United downs had already done this in 2019 and have just finished up testing??

[@ramblerandy2397]

Wonderful episode. Quite uplifting in seeing the very technology that brought us the oil/gas burning era being put to great use in a much better way. That put a charge in me [sorry, couldn't resist].

[@iteerrex8166]

A football field is a good visual for 100 meters. So they are going down 46 football fields down, mostly into granite rock. Crazy!

[@Thegeordiemonkey]

Part of Newcastle University Science area that has been built this last 5 years or so is run fully or not far off geothermal energy from a hole they dug a while back tapping in to that Northern section on the map you showed.

[@niccox1738]

Any update on how this is progressing, and are there plans to have a follow on report?

[@twoartistic]

Love this!
