German mechanical engineer here. Greatly appreciate the in-depth video as always. I wanted to point out some big potential drawbacks of geothermal energy you did not include in the video. 1. Geothermal energy is not boundless as the video suggests. Following the first law of thermodynamics, a natural occurring geothermal reservoir (or aquifer as it is known in the field) or a man-made one thanks to EGS, is bound to lose temperature over time due to the fact that we pump out more heat than we reinject. This inevitably causes a decrease in the aquifers temperature, which in turn causes a diminished steam production which then reduces the amount of generated electricity by turbine/generator. Some sources suggest that the average aquifer requires roughly 30 years until the original temperature is reached again. 2.Scaling/ Fouling. This is probably one of the greatest technical problems with geothermal plants nowadays. Since the water used for direct steam generation or secondary cycle heat transfer is coming from ca.3-4 km underground, it is saturated with different minerals, the most common being SiO2 (quartz) and CaCO3 (limestone). The chemical nature and type of the minerals is highly dependent on the location of the geothermal plant, but you can research them further if you'd like. Rapid changes in pressure and temperature along the pipes leads to the precipitation of these minerals (Scaling/Fouling) and unfortunately quite frequently to the failure of vital mechanical components such as pumps and heat exchangers. This leads to frequent halts of electricity production in most geothermal power plants. Sorry for the long comment, I just feel passionate about the subject since it was the topic of my thesis!

Not an engineer here, nor do I play one on tv, nor did I stay at a Holiday Inn express last night. Now that this is out of the way I do wonder, regarding point 1) simple solution is to alternate production between sites, more or less like farmers don't plant crops in the same field year after year. Leave things to warm back up and then restart production. If you have enough sites that you can rotate in and out of production you should be sustainable. For point 2) Best but also horribly expensive way to deal with this is to have all your piping in a closed loop and not use ground water as a heat exchange fluid. What I could "envision" is something that would look a bit like a large tunnel boring machine that would have all the hardware on board, tilt it at an angle, let it dig, once it reaches layers of rock hot enough the outer casing ends up acting as a kind of heat sink and all your power generation hardware is inside the machine, all that is needed is to run cables so you can connect the power generated to the grid. When the rocks the machine is sitting in invariably cool down, it's able to start the digger head again, dig itself a bit deeper and start production again. Hard to explain what I have in mind but I think you can get the general idea.

Nuclear is honestly our best opinion for a future power supply. Granted we'll still need quicker acting plants to help quickly adjust the grid to demand. Those will probably be gas power plants. Though I guess in time you could make some stuff that can provide stable but quick power to replace those. I just don't get why we don't go the nuclear route when we know it's safe, to the point nuclear is safer than even solar and wind some how. Plus the long term cost is actually really really good, since they last so long and the method of producing power is efficient for power generation and cost of fuel per kilowatt is really good.

While much of the interest is in heating we must also remember that a huge portion of our energy use is cooling. A drill/well wouldn't have to go down far enough to capture heat. In any geographic area that is burdened by cooling costs, using the shaft as a heat exchanger can work backwards without the excessive depth required to reach a heat source.

infant jones I also find it interesting that those who support thorium are largely unaware of the fact that the USA has actually used thorium in commercial reactors in the past, but the costs of using the fuel were greater than its benefits of production. Shippingport 1977 Reactor 3 Ft Vrain 1984 Reactor 2 Both of these reactors were Light Water Breeder Reactors that did not significantly outperform conventional PWRs. So when these people point out the benefits of a LFTR, what they fail to recognize is that the considerable benefits are largely based on characteristics that thorium itself does not necessarily provide.

The seismic risk is not the only risk. In Germany there is a city where they punctured a waterproof layer of stone that lead to water floing into lime stone and that then expanded and lifted the city center over a meter up, damaging many houses.

Breaking up a lot of underground rocks, no matter how you do it, is a rather risky thing to do. Geothermal energy is worth looking into. But we need to be careful about what can go wrong. Earthquakes, sinkholes, and unexpected contamination of groundwater, are all things that have to be carefully considered and allowed for.

It would have been worth mentioning geothermal energy used directly to heat homes and buildings. You don't have to drill down as low since you don't need as much of a temperature differential, and it still lightens the load on the electric grid. In fact, it's actually a lot more efficient to use roof top solar panels to power a pump in a home geothermal system than to use the power from the panels directly to heat the water.

That depends on the location imho. Fluid temperature of the thermal solar panels should be way higher than the ground temperature few meters below. So given a large enough thermal solar panel size one can skip the heat pump on a good sunny winter day.

@@darked89 I would argue it works well in the north as well, even in arctic regions. Combined power and heating, and here we are talking temp differential for the power generation and heating store the water which is your heat storage medium namely as its inexpensive at just slightly above 100 F and store in in a receiver underground where temp is say 50F. Connect to heat pipes so you are not sending energy to pump, then use the temp differential between ambient and that and use both thermal electric generators and Stirling engines to generate electricity and even compress to raise temp above receiver temp if needed. In summer you have a sun that nearly never sets and your store that energy in your water reservoir. It will take a lot of volume but you can make it inexpensive if you have a few homes sharing such.. However for a town or city the volume would be the issue I suppose. Probably better to store in magnesium hydride than water just because its 78KJ per mol H2 and use the sun and solar concentrators to get up to 300C in summer to release the H2 at atmospheric pressure.

Most opposition to nuclear energy is based on ignorance. Change my mind. Edit: To summ up most answers for those mentioning Chernobyl and others. Just like a plane crash, these examples are easy to point out sources of a couple tens of thousands of deaths. What people always forget mentioning is the estimated 4+ million deaths _a year_ from air pollution. That's one part of the ignorance i was talking about. A couple accidents costing a couple tens of thousands of lifes cant realistically ever outnumber the lifes we lose each year by polluting the air as we do. Then there is also climate change, which is a hard to grasp concept for some, but way worse than a couple tens of thousands of deaths by itself (and potentially irreversable if we keep continuing). Then there is the fact that newer types of reactors can pretty much make a meltdown more or less impossible, not even talking about using thorium. Keep in mind that nuclear energy was - and still is - a very new energy source in terms of progress. The only real problem would be the waste. However, it's better to be able to contain and store waste, compared to just pumping it into the atmosphere. Keep in mind that radioactive elements with short halftimes are the dangerous ones, but gone in a couple years. These with millions/billions of years of halflifes are basically not very dangerous, since they dont radiate a lot. So the most problematic ones are those with halflifes that make them radiate dangerous amounts, but still stick around long enough to cause problems. Still, in comparison this is a smaller problem to deal with than air pollution and greenhouse gases by far. Also renewable energy sources are neither renewable, nor completely green and it's not possible to sustain the planet by them alone, not to mention all those batteries needed.

1) Fracking fluid is not toxic. While not pleasant, it's actually safe to consume directly. 2) Shale oil fields occur at much deeper depths than aquifers. Even at their closest, aquifers are separated from shale oil by hundreds of feet of impenetrable air/water tight rock.

Granted it will not as efficient but you save that energy to be used in winter. Just a thought. Method number 2: Use all the excess energy for electrolysis of water into H2 and O2, save those two in liquid form in large storage tanks and than using hydrogen fuel cells you can generate electricity. In my opinion method number 1 is the most logical since you probably already have all the necessary infrastructure you just pump water back in the dam. What do you guys say about those methods?

Another side benefit to geothermal is that you can more quickly mine and process lithium and other valuable minerals using the same process that heats the water used to produce energy. When you circulate these liquids you also pick up a lot of the mineral brine that is embedded in these rocks, and some of that will be lithium if placed near a lithium deposit.

Molten salt breeder reactors are the actual future in this regard, almost all of the claimed benefits of thorium are just in the type of reactor, not thorium itself. A lot of research is still needed on these types of reactors however, while we already have very good uranium designs ready to go at any time. The main issue is that in the US there's loads of opposition to nuclear that ends up leading to construction times and costs being 2-3 times that in the rest of the world, while the anti-nuclear lobby is trying to force a nuclear phase-out in Europe (which has only really occurred in Germany so far, leaving them with with a 500 billion dollar failure to reduce carbon emissions and a much less stable power grid). If molten salt breeder reactors become viable, even with the benefits of them over light water reactors, they'll immediately become a major target of the anti-nuclear lobby. Nuclear already being extremely safe, efficient, and reliable hasn't stopped the anti-nuclear pro-"renewable" lobby (Greenpeace, Sierra Club, and most importantly the fossil fuel industry, /especially/ natural gas) in the US and Europe from making blatant falsehoods and misconceptions common beliefs in order to drive up public opposition to the technology, I really do doubt that even better reactor designs are going to change this.

CA often has to curtail solar in the spring and the fall (lots of sun, low A/C demand), but not usually during high-summer because there is enough A/C demand to offset it. I was really surprised when you mentioned Moss Landing. Why would PG&E put a battery there? But then I remembered, Moss Landing is part of what is almost an island-grid. It has poor connectivity to the main CA grid, and the natural gas supply is also constricted. (If I remember right). It used to have a coal plant long ago but it was eventually replaced with the gas plant. People got really sick of that coal plant causing acid rain which stained everything. Homes, Vehicles, Boats... it was pretty yuch. I think PG&E's purpose in putting in the batteries might be to clip the peak usage times in order to avoid having to put in another NG generator (or have to expand the NG supply to the area). It actually makes a lot of sense in that light. -Matt

It is a bit the same as getting out liquidified dinos out of the ground, i am sure when oil industry started it seemed infinite supply as well - turns out it is not *that* infinite. Energy demand grows constantly. Fortunately this can be alleviated, using ground heat to heatup buildings is quite common where i am. During summers those buildings are being cooled by AC and if you pump that heat back into the ground instead ground will act like one giant battery in this case and it might actually be net positive amount of energy put into the ground. Do the same with geothermal power plants where possible, "remote cooling" is starting to become a thing, where centralized heating using waste energy of power plants has been a thing for a long time, over here i hear they are starting to offer summer time cooling by pumping cool water into the same pipes.

No chance of what ???, the last thing we need is more Nuclear Power Stations and yes I know about how badly we need the electricity and how environmentally friendly it is and all that Bullshit, the problem is when it goes wrong the Conciequences for the world could be Catastrophic if enough atomic pollution was blasted into the Atmosphere. It would kill every living thing on the planet eventually, whilst I agree we must do something to try and cut our man made emissions it needs to be done Globally not just a few country's taking action while the likes of China and India carry on regardless burning fossil fuels. Unless we all change its not going to work and all this about electric vehicles won't work either if there's not enough power stations to produce all the electric these vehicles are going to need worldwide. This change over should have been started years ago Not left to the last minute but of course the oil producers wouldn't have liked that and scuppered any chance of it happening. The oil Barons are beginning to see where their industry is going and they ain't happy about the fall in oil prices but the only way is down from here now on as demand drops because of people's desire for electric vehicles goes up as battery storage gets better. The glory days for oil is over. The Saudis and others have had a field day with oil sales squandering vast amounts of money on Bentleys and Rolls Royce cars and flash speedboats plus other extravagant lifestyles.

I would consider the possibility that if drilling caused an earthquake...it may have released the pressure that was inevitably going to get worse before it was released. Its not like drilling adds that much energy, so the whole thing was inevitable.

Great stuff, had often wondered why there wasn't more geothermal... [tho clearly never enough to actually bother looking it up] So thx for the info. What about the idea of using simple pipes to provide underfloor heating direct to buildings? [obv in suitable places.] Loved the subtle little Yang plug.

Pol Gabaldon Im not sure why everyone’s being a dick to you. Even if solar isn’t yet a viable enough option to please everyone, the only way the technology will ever improve is if those who sell it are able to continue selling them as they continue to improve. Also, solar panels can easily absorb more energy than it took to produce them, even taking the mining into account. To suggest otherwise is absurd

Hello Real Engineering, I seem to remember watch about high efficiency perovskite solar panels that would be mass produce very soon (it should have started in the end of last year originally) but don't remember of which company it was and can't find the video/passage. Would you remember or would be able to find it ? Thank you.

Wouldn't bringing heat up from underground faster than it's "natural" speed cause an increase in the equilibrium temperature of the biosphere, i.e. exactly the problem already caused by the greenhouse effect?

Very interesting. I have considered the fact that there is more than enough energy under our feet to reduce our carbon footprint by at least half, using the cracked rock method.. As mentioned, using another gas with a lower boiling point reduces the level at which is needed to produce power,, and the safety far outruns using atomic power in terms of safety. However, there is another method that is being kept very much hidden. In Australia, we had in western Australia a plant that used the sun. Using mirrors that were used to directvthe suns energy via parabolic mirrors directly onto tubes at the centre of the oblong mirrors this heated the fluid in the tubes to a huge temperature running generators, once built the maintenance was very basic as there was little to go wrong. To my amazment this plant was shut down, why is a mistery as for a start if was far more productive the solar cell fields, all the active parts were above ground so easy to work on, it was easy to add to to produce more energy and offered a number of different fluids to run through the centre tube so that even when not in complete sun, the e nergy was still produced. Therevare other ways of making electricty such as hydro plants but not huge dams , as there are many fast flowing rivers through out the world that can and should be used to produce cost effective energy just from their flow rate. A look at the amount of engergy produced by some of the smallest units says that all,forms of energy supplied by nature are really worth looking at.

There is another potentially huge benefit of geothermal, which is as a sink for heat pumps. Turning electricity into heat is 100% efficient, but electricity is expensive. Heat pumps can be more than 100% efficient, because instead of converting the electricity they use it to move large amount of heat energy around. The ground is pretty much always a better heat sink than the air, when it is a hot day outside and we want AC, the ground is still about 50F degrees just a little below the surface, which lets an AC unit run much more efficiently. When it is a cold day and we want heat, the ground is still about 50F degrees, so pulling heat out of the ground is much more efficient than pulling it out of the cold air. Depending on the price of natural gas, a furnace might be cheaper for heating today, but an air based AC unit certainly won't be. And these wells don't need to be deep, going down where it is hot isn't even helpful, because we want a moderate temperature to run heat pumps for both heating and AC. AC is one of the biggest drivers of electricity use, making it even a little bit more efficient makes a big impact on overall electricity use. And these heat pumps are energy source agnostic, they can be powered by a geothermal plant up the road that is drilled deep enough to produce power, they can be powered by solar, wind, hydro, batteries, nuclear, or even fossil fuels. Ultimately geothermal isn't going to form the bulk of our energy supply, it isn't cheap enough to compete with solar or wind in most places, but it does in some where the conditions are just right. And in those places where it works, it is a good supplement. Geothermal should also be fully throttle-able, meaning it isn't a limited base-load power supply.

Could now make a video about thorium because it seems like a lot of people dismiss nuclear energy...

Geothermal = limited, nuclear = the future.

There are some domestic projects by private ma and pa operations , that dig 8 foot deep and lay 6 to 8 inch diameter pipe . Then air is drawn through either by convection or fan they are receiving 52* to 58*.air temp year round heating greenhouses along with the solar. With some left over to heat the home. This is in Idaho .

Absolutely awesome !

Russia was build geothermal power plant in Kamchatka (part Ring of Fire). It produce 50 megawatt. That looks like small amount but is cover local needs.

yeah, and if industrialized to the extent to make a dent in global electric needs, well, I'm not sure how I feel about accelerating the cooling of the dynamo that protects us all from solar flairs and cosmic radiation. At the most basic level, geothermal is taking the heat out of the ground and dumping it into the air to generate mechanical or electric energy. thus my second doubt about geothermal electricity on a mass industrialized level. There is a limit to how much heat the atmosphere can dissipate into space before things get a tad toasty for us down here on the ground. The latter being why city-planets (Ecumenopolis) in sci-fi is not that realistic unless you space people out significantly to reduce total heat output from energy usage.

@@Zarcondeegrissom Any method of energy generation will eventually turn into heat though, that's a fact of thermodynamics. If we looked only at the power generated (ignoring all emissions) wind creates the exact same amount of heat as coal. It seems counter-intuitive, but it makes sense really, all that energy goes into heating homes, powering ovens, driving electric cars, etc, and all of that generates heat either directly or through friction and other losses. What matters isn't so much the energy generated, but the energy lost to space, if we lose energy at the same rate we gain it, huzzah! We won't change temperature, but right now we're decreasing our rate of energy loss with greenhouse gases, so we're warming up to a new equilibrium, which ain't the greatest. Ultimately, global warming is all about managing our thermodynamics.

"Any method of energy generation will eventually turn into heat though, that's a fact of thermodynamics.", yep, true, and sure I implied as much in closing (energy usage). "if we lose energy at the same rate we gain it, huzzah!", again, yep, (There is a limit to how much heat the atmosphere can dissipate into space). And agreed about managing thermals. I'm just not sure you understood the scale of what was being suggested by this vid. we are not talking about using geothermal heat that otherwise would naturally rise to the surface at natural rates, what was being proposed is digging down and pulling more heat out of the ground than would otherwise naturally rise through the ground to the surface, thus adding more heat to the atmosphere than what naturally arrives here from the sun or through normal geological heating. That's what I have doubts about. (sarcasm detected) Burning fossil fuels is bad, so let's add more heat to the atmosphere from another place it normally doesn't come from at the proposed rates needed to augment the electric grids worldwide, lol.

@@Zarcondeegrissom I'm afraid you've still not understood. All of our energy comes from heat, all of it. Solar power utilises the heat of the sun, coal power uses the heat of burning things, nuclear power uses the heat of splitting atoms, every kilowatt of power produced has at least a kilowatt of heat that went into making that power. Getting energy from the core of the Earth would dump just as much heat into the atmosphere as getting the same energy from solar or wind, the source makes no difference outside of emissions, which change the Earth's rate of heat loss.

except, the sun still shines if you don't use a windmill or solar panel. thus that source of heat is not being changed (only where it's converted into heat the atmosphere must dissipate). Whatever, you'll figure it out on your own eventually. you're so close to grasping what I first typed. good day.

What if the 2 km whole has a collapse and blockage stronger than the water pressure, say, three fourths the way down? How do u fix that? Move the entire facility and bring the drill rig back. I suppose it could be done, but sounds extremely expensive. But good video tho, and I've always liked the idea of geothermal.
