''During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.'' Wikipedia - On short for the ones that are not so open that they brain fall off: CO2 produces OXIGEN. I rest my case.

@@wino99999 Sorry dude. I think you're confusing energy and power. 57 W/h? What is that? You divide 200 MWh (energy) by 350,000 homes you get 571 Wh/home. That's energy per home, and it's consumed across 1 hour, so the power is 571 (Wh/home)/1h = 571 W/home. That's how much power each home is consuming. Do the same for 35,000: 200MWh/35,000 = 5.71 KWh/home or 5,710 Wh/home. But that energy is consumed by those homes across 10 hours, not 1h like before, so the power is P=(5,710 Wh/home)/10h= 571 W/home, i.e. same power, as expected. Hope that helps!

When I was in graduate school I was doing research on hybrid electric vehicles, specifically the Japanese model of the Prius. At one point during my first year in the PhD program I realized that no one had ever analyzed the radiant energy distributed into the atmosphere as a result of the roads which get quite hot as compared to flora that would normally occupy those spots and had asked my graduate advisor if I could do that on the side. The basic answer was that the only way to get funding was to bite off on the CO2 emissions as the primary driver of climate change and since my hypothesis wasn't associated with that end result, no funding could be provided. So if everyone in the scientific community only gets funding if they internalize the idea of CO2 being the primary driver of climate change then you will never have information to the contrary regardless of if it exists. I dropped out of the PhD program about 6 months later after realizing that even in STEM programs graduate school was a complete waste of time and money.

But that is not the case for water. _“In agronomy, the effects of elevated CO2 on plant water use efficiency and drought resilience are extensively studied. One of the key mechanisms through which elevated CO2 levels improve water use efficiency is by reducing stomatal conductance and, consequently, water loss through transpiration._ _“Stomata are small pores on the surface of plant leaves that regulate gas exchange, including the uptake of CO2 for photosynthesis and the release of water vapor through transpiration. When CO2 levels are elevated, plants can maintain the same or higher rate of photosynthesis while reducing stomatal conductance. This reduction in stomatal conductance leads to a decrease in water loss through transpiration without significantly affecting CO2 uptake, resulting in improved water use efficiency.”_ -ChatGPT 3.5 Additionally, some crops (legumes & sugarcane) make their own nitrogen fertilizer, so for those crops increased yields do not require increased nitrogen fertilization.

The biggest takeaway for me is that since CO2 doesn't require cryogenic assist to be compressed into a liquefied state, it is much more efficient than compressed air. For utility power plants, I don't think the CO2 battery's low energy density will play much of a factor in deciding whether to use it in comparison to other technologies, though the short vid of the Tesla with a CO2 dome on its roof was a good bit of fun. Thanks for the great video. I see so many videos like "Graphene Eardrum Replacement Surgery Enables Supersonic Hearing", and it turns out to be nothing more than a calculation someone did on the resonant frequency of a piece of graphene the size of an eardrum, and is nowhere even close to becoming reality. That there is a CO2 pilot plant currently operating and a contract to scale up this tech in a real-world application is just wonderful and makes this video so worthwhile. Thanks for covering this.

[@user-xo2yo6jl3o]

I think you might be missing something: heat transfer during compression and expansion. --The pumps will generate quite a lot of heat when charging (during compression), and will sink a lot of heat (cool the surroundings) when discharging. Pumped hydro or batteries don't have this problem, but compressed air does though probably to a lesser extent because the air doesn't undergo a phase change. The bigger the battery, the bigger the problem. --Have you included components for heat transfer to the external environment? (fans, pumps, etc.) A large unit could either frost up and stop working efficiently or overheat and fail. And if you use an external source of energy for heating the liquid CO2 the efficiency drops. If you expand too much CO2 without heating the storage cells the remainder will solidify. (dry ice) I would expect that the problem will get worse as the battery gets larger. There might be a good solution at small size, but not at industrial size. In other words, will it scale? Time to do some thermodynamic modeling. And finally, CO2 is actually a toxic gas when concentrated. The fatal concentration is about 10%. So leaks are more hazardous than compressed air.

[@insertphrasehere15]

I suspect that the heat exchangers are not part of the simplified diagram, but I think that the water pool that is shown is meant to be the heat exchanger. That pool of water will be warmed during charging, and then cool down during discharge. insulating the tank is actually an advantage in this scenario. while this is some technical hurdle, I don't expect that a water tank will require a lot of extra space, and is still miles less complicated than existing compressed air systems. As for toxicity, I suspect that's why their system is shown in open air setups (not inside a building).

[@Thomas-pu3qf]

i worked with the oil rigs and diamond drills back 06' to 15', you can control overheating cooling systems to address that problem, on the drills we had to deal with our hydraulic system overheating so i believe it can resolved, i am not egineer so i cold be wrong .

[@TimeSurfer206]

5:31 "A second Advantage is that the system incorporates a thermal energy storage system to capture the heat released when the carbon dioxide condenses and uses that same energy to evaporate the liquid carbon dioxide when the battery is discharging. This makes the battery more efficient than a liquid compressed air battery which requires external heating to boil and liquefy the air." Is this what you were referring to? And yes, CO2 is toxic at that level. I'd still rather be around that leak, than live steam.

[@fhuber7507]

A thermal sink system can store the heat of compression and provide it for the expansion cycle. It's a huge "barrel" of sand with pipes running through it A thermal mass with a means of transfer of heat, and an insulation blanket. A simple 4 gallon water heater with normal insulation can keep that 4 gallons above 100 F for 24 hours, starting from only 120 F when the power goes out. (How would I know that?)

I think it’s important that it remains emphasized that this doesn’t mean we can still keep pumping CO2 and other greenhouse gases into the atmosphere at the rate we are currently (which is still rising at an alarmingly exponential rate) CO2 and other greenhouse gases from burning hydrocarbons like fossil fuels, will not be canceled out by CO2 Batteries and Carbon Capture alone. The battery tech and Atmospheric CO2 capture, removal and storage are all still very expensive and inefficient and or complicated technologies that are very much still in their infancy and thus will both need more time and significantly more funding and research to further develop their capabilities and assess their feasibility. As both are still only variables in a very long and complicated equation where the only constant really, is it’s continued variability. Also, something to consider, is many companies with “Green Initiatives,” pledging to be Carbon Neutral by a certain date are heavily relying on Carbon Capture technology which is currently way too expensive to feasibly be economically capturing CO2 produced by industry, energy generation and transportation even with the efficacy and financial cost benefits that would come with economies of scale of these technologies as they continue to evolve.

Storing underground makes a lot of sense, it does not upset the landscape or use up valuable space where more solar or wind turbines could be sited. Why not build in some redundancy to the system and make it multiple smaller domes that could be isolated easily for maintenance or replacement in case of seal failures. Smaller bags also fit better into mines and could be designed to utilise the maximum space for efficiency in the mine. A modular and standardised design also means, it could be easily mass produced and scaled. As more sites come on line costs should come down and an industry be created to maintain and produce parts for these systems.

[@flmuzk9292]

Not sure if I missed it during your presentation. Where did the energy to drive the CO2 compression come from? If taken from the system electrical generation, then it seems that would at the least reduce the system efficiency even more or reduce the time electrical generation is available for retail/commercial consumption. This seems to me to be an important component of renewable energy generation that is often missed. Or at least not clearly stated.

[@lexpox329]

The 'round trip efficiency' by definition includes any and all losses due to operation of the system, in this case it takes into account the energy needed to compress the gas from the bladder into the liquid tanks. As to where the energy originally comes from, all energy storage will have the same overhead in terms of making the power so its dropped from the "equation" because it appears on both sides as it were. These types of comparisons are really for just talking about the cost of storing the power once you have made it from a renewable source (coal, gas, and nuclear fuel are the storage for their types of power). As such to determine the actual cost to the consumer for the power you will have to include all the costs (Generation + Storage + Transmission) to get the per KWH price. In this video he is just comparing storage costs. A side note: talking about energy storage is relatively new due to the inherent energy storage of fossil fuels. This is one reason why I often respond when people say "solar is now cheaper than coal", that its really not yet, due to the oft quoted articles not taking storage costs into account for solar. There of course is the also not included environmental and health costs of burning coal (smog and CO2 emissions) but power companies are not required to pay those costs as of yet, so for the present the economic reality is that solar + storage has to be compared to coal by its self; and its not cheaper yet. I hope that helps you understand the video better.

[@dustysmith4654]

It was easy to miss, but that's the whole point. The electrical power comes from the excess renewable power (wind mill or solar panel) being generated. During times when windmills and solar panels have more wind or sunlight that can be used at that moment, the excess can be stored as it is generated by powering the equipment that compresses the CO2. The pressurized CO2 is then released and vaporized and then in turn, drives a generator which provides electricity to the grid.

[@keithedwards9953]

There are 2 cost factors that weren't mentioned in your video that I'm curious about. The price of the land needed for such a large battery, and the cost of maintenance needed for it. I'm not saying it's a bad idea, but all cost factors should be considered into the true cost per MW.

[@sjsomething4936]

Without question land cost will be an issue sometimes, (ie to store output from a big wind turbine array in Napa Valley California vs. offshore wind farms in a remote area) while in other places it’ll likely be a negligible factor. I’m also curious if this can be located anywhere within the grid as opposed to close to the generation site, I don’t see why not. That’d make it much more adaptable and less influenced by land cost. Making the components vertical might also be worthwhile, you could literally attach one onto the side of a new building and have backup power for the building. I’d expect maintenance to be pretty low as it’s pretty much all just standard plumbing, piping and other equipment but it’s a very valid point, typically it would be factored into the LCOS that was mentioned. Not doing so would be a large divergence from the normal way of calculating long term LCOS.

[@emmanuelgutierrez8616]

What about the biggest one missed, Where does the co2 come from, thats is still too expensive to capture.

[@tallest4eva]

Because the location of the battery is not dependent on anything except the location of the generated energy, the land use should not be that much of a factor. Plus I believe he mentioned the energy density of the battery being low, which for stationary batteries is basically the land use factor. As for the maintenance cost, it should be quite similar to a coal power plant or any power plant that uses a heat exchanger via a working fluid to make electricity.

[@Traqr]

@@sjsomething4936 Seems to me that it could be located anywhere between the source and the customer without adding losses, and I love the idea of a future cityscape with big white insulating bubbles and rooftop greenspaces on top of all the buildings! Of course, they probably include them with generation because a 100MW system is a lot cheaper than 100 1MW systems, and the grid's already designed with a high-power node at the source.

[@TheXasTube]

land cost could also be reduced/removed if this system is vertically integrated into the facility providing the energy input. or to put it more blunt: just put (parts of) the solar/wind farm ontop of the building that holds your CO2 battery system. not like those facilities care much if they are a few dozen m's higher up or not.

One great thing about this energy storage system is that it works directly with our AC system, since the motors and generators are AC themselves. This means that it could give renewables like solar or wind some "inertia" which mimics the one that normal powerplants have, dampening fluctuations in the frequency of the AC

The safety of this system is incredible ! this is a point you have underestimated in this beautiful video . 80 % efficency is not bad at all ! As Hidro on mountains rarely reach this efficency (charge+discharge) due to long pipelines .

[@Syvtek]

"Safety" in terms of not erupting into a fireball or irradiating a large area after a catastrophic failure. Sure. However, an above ground dome as shown is rather unsafe. A containment failure of this volume of gas would send a river of oxygen displacing CO2 along the ground, suffocating and killing any animal life in its path and pooling in topographical depressions. (There are places in the world this phenomenon happens naturally and it is terrifying how deadly it is.) If implemented, a reservoir of CO2 is much safer to everyone stored underground so that it may not flow anywhere in case of failure. I wouldn't live anywhere below one of these power plants if it used a dome.

The beauty with utility scale power storage is that it can be placed just about anywhere. The storage tanks have some hazard to it but minor since 70 bar ain’t that bad. The big dome is a big dome with something we already know. So sounds good. We must remember that batteries, for such use, are shifting towards LFP… which is way cheaper and since volumetric and gravimetric density is less important in such batteries, they should do well. You should also investigate a Calgary cie called eavor (I think that’s what it’s called) which kinda stores energy but not from the grid but rather generates base load energy when needed and when wind/solar are pumping out energy, it simply leaves heat in soil to be used with greater efficiency later. A combo of cheap energy storage, easy to install anywhere base-load energy production with built in delay generation and ever cheaper sun/wind/wave energy generation, we can SERIOUSLY reduce our dependence on fossil fuels. The beauty of the above is that ANYBODY, ANYWHERE can use them to some degree or another. Especially the baseline and storage.

The best part of this technology it's even something that it's not talked about, if we were to accept a higher energy inefficiency this would be the perfect way to export energy for countries with excess production with infrastructure that for the most part we already have, for example just place solar panels all the way through the Sahara desert and then export compress CO2

They view the world as though everyone lives in warm places, that's the whole problem with the green energy movement. Most solutions are NOT useable in most of the world.

That is exciting; I forgot to consider the liquid cycle for CO2 storage. While watching the video, I imagined using the cycle to transmit energy too. The pipe carrying liquid CO2 would absorb heat along the way, increasing its potential. The gas return pipe would serve as the dome. So elegant! I love it. However, the cost factor for pumped storage needs to be explained; I wonder if it excludes the recreational value and agricultural side-benefits of pumped storage. Further, if (not pumped) storage is from a stream, where water is just held back for flow during electrical demand cycles, the cost and benefits may be even lower. I'm especially concerned with this because Pluvicopia includes such storage as part of its benefits. Pluvinergy produces excess water, so percolation into the water table is one more benefit, to remove water from the oceans and transfer it to land storage for sea level adjustment. (Look at the numbers before you brush this off, I am aware that 1mm of sea level equals 361 km3.)

Every gas has a physical property known as its specific heat capacity. The heat capacity of CO2 is greater than that of N2 or O2, meaning that the more CO2 that is present, the more heat energy it can hold. Of course, all atmospheric heat is eventually dissipated into outer space, but the higher the heat capacity of the atmosphere, the more slowly the dissipation. Water vapor has an even higher heat capacity than CO2, but the difference is that water vapor precipitates out of the atmosphere as soon as its partial pressure reaches a certain point, so it exists in the atmosphere at an equilibrium concentration.

Technology could find a way to connect straight to those stacks and use a vacuum system, then take it to a plant that could separate it from the other gasses. Sure, startup for that would be high. But again, so are water and sewage treatment plants. Then, they could even add on to other high carbon producing areas. Sure, it costs money to start as everything does. But in the end it would cost less in the long run and cost less. Once you can find a way to capture carbon straight from the air itself the means of separation will exist and the only major issue would be how much could be taken from the atmosphere before an ice age would result. This could be dine for other gasses such as methane, which seep out of the earth, land, and oceans. Again, we could do many things to help the environment. To what extent would we then hurt the environment and need to produce vs take away. For instance, if we take too much growth of plants, they would suffer. Removing too much could cause cold climate etc.

[@misterbulger]

Could they use natural gas as the compressed gas? Would be able to use that for backup fuel as well should the unit go offline and could be connected to existing pipelines.

[@PelenTan]

I like this idea. But I have a question. Or actually a future question. I understand the layout _now_ during the early stages when all sorts of things need to be checked. However, it seems to me that this would be so much better if buried. For example, take a plot of farm land. Scrape off the top soil. Use standard strip-mining procedures to dig down 20 or 30 feet. Build everything on that flat. With all sorts of extra dome space. Fill it back in. Put the top soil back. Continue growing. Even with huge combines, there isn't that much added weight to have to account for. And if CO2 _does_ escape, the plants growing on top would gobble most of it up. Hell, you could even make that part of the the overall cycle. Continual bring in CO2 from industry to replace the old CO2 you release carefully into the crop. Which would generate bigger and faster yields which would help offset the cost of getting it from manufactures that capture it for you.

[@ipp_tutor]

I think an even better idea would be to use one of those huge caverns they use for compressed air wherever it's available, don't you?

[@eggos5074]

@@ipp_tutor not all places have the geologic formations for that kind of storage when applicable it can be used however they need to design the system to be used in more locations to be vaible.

[@gotafarmyet4691]

The weight of the soil on top will be a issue as the tank will be compressed by it. Under different loads when full and empty will also add issues which is now additional cost. The benefit of burial is in case of a leak it will slow the release. Which will now be harder to fix and much more dangerous to fix. Nope better to leave it above ground. It does bring up the issue is what is the impact caused by a leak, as name a company that doesn't put profit first in the long haul.

[@debbiehenri345]

Bury 'em - great idea. Much better than having to look at the horrible things. They take up so much space that we 'should' be using for crops, rewilding, forestry, or some sort of 'greening.' Not sure that 'leaks' would be taken care of by plants soaking it up, a leak might produce too much for them to cope with - Goodness me! You realise you might have stumbled across a potential disaster situation here. CO2 sinks right? Well, you'd have to be really careful where these are sited, because if they did leak and the escaping gas sank into a hollow in the landscape, possibly where people live, there's the danger of suffocation - it's what happens in low areas where there is volcanic activity. I remember there was some little village around an African lake, everyone perished because CO2 bubbled up from the nearby lake.

[@DragcoDavid]

Probably what I love most about this idea is that... it basically adds a economic reason for carbon capture, aka capturing CO2 at the plant, and extraction out of the air/ocean, in order to produce these large scale batteries. They never listen unless they can see a profit in it!

[@erict.watson2460]

I think you mean _immediate_ profit, but I could be wrong.

[@5353Jumper]

Would be great if Carbon Capture was easy and efficient. But it isn't. It takes so much energy to power carbon capture if that energy is created with fossil fuel burning it actually emits more than not doing CCS at all. So they use green energy for their CCS. Which is stupid at best and downright evil at worst. Why not just plug that green energy into the grid, stop powering things with fossil fuels in the first place and cut emissions at the source instead of inefficiently scrubbing them later? Other high emissions industries may be able to justify CCS later if it gets more efficient, and help justify it with after market value like this. But for now CCS is just a big steaming pile of petroleum industry propaganda to keep us burning their products longer and maintain their revenues.

[@ThePurplePassage]

@@5353Jumper Because fossil fuel power sources are dispatchable, whereas renewables tend to be intermittent and grid demand is variable, so you can get spikes of renewable supply when demand is low that exceed the present capacity of the grid to store. At that point you can either furl the wind turbines and otherwise waste the renewable power, or you can put it to use.

[@5353Jumper]

@@ThePurplePassage still does not mean CCS is a good idea for the petroleum industry. And did I say replace fossil fuel generation 100% with solar and wind? Nope. A blend is best but we need to get to a point where we are actually meeting daytime needs with green generation before that is even a problem, long way to go particularly if the petroleum industry keeps sucking all the materials, labor and funding from actual green generation projects. In some regions natural gas peaker plants make great sense, as long as they are relegated to secondary fast spin up generation instead of the primary generation. Still does not mean CCS on them is a good idea.

[@ThePurplePassage]

@@5353Jumper I agree that where CCS is a net emitter (the emissions generated in powering the plant are greater than the volume that is captured) then yes it is obviously foolish to use, and yes most jurisdictions are not at the stage where electricity generation is wholly or even mostly carbon free. But in the event that it was, or if like I said the low carbon energy generated would not be stored or used (favourable wind conditions for example) then why would you be opposed to the use of the technology then? If your goal is to abate the effects of climate change then negative emissions technology is a good thing (and I stress again, provided it is a true case of net negative emissions). The less the volume of green house gases in the atmosphere the better and the fewer the number of extreme weather emergencies, migration flows and possible water wars will occur

[@jami1974]

I was thinking..In sea areas, why not just submerge long pipes under the water, stick a valve on top, use wind power to pump air to the pipes, and when you need the stored energy, you release the valve and use the air pressure to rotate a turbine. Let water pressure do the work. The air pressure keeps the pipe intact, regardless of it's length.

[@dougandersen645]

Who has proclaimed that carbon is pollution, why, none other than our all knowing government. I have said for years that carbon is the answer, not the problem. Carbon in the atmosphere has been many times the level it is now. Higher levels of carbon has made for a greener, healthier planet. The reason the politicians have declared it pollution is because we humans are responsible for creating an infinitesimally small amount. In their brilliance, they have found a way to tax it.

[@Raven5431]

Pretty sure power plants are already starting to use carbon in a closed loop system instead of steam.

[@TwoBitDaVinci]

[@haute39234]

One question I have is how quickly can the CO2 storage react to changes in demand? Battery storage facilities are really great at near immediate releases of electricity to respond to demand spikes. It seems like C02 storage would need at least a few minutes, so perhaps great for longer term demand increases, but in conjunction with other "instant" demand usage smoothing facilities.

[@KenJackson_US]

Maybe they could add a small lithium battery to handle instant demand while the generator starts.

[@tomrogers9467]

As the gas is powering a turbine, the volume/pressure of the gas could be regulated to provide the required turbine speed, and adjusted to demand. This is how a typical steam turbine generator works, steam pressure is constantly being adjusted.

[@ipp_tutor]

@@tomrogers9467 Agreed. Although you can only adjust it so much based on the input pressure. I think he makes a fair point as one of the stages of the process involves vaporizing the CO2, and that takes time. If you deplete the CO2 going into the turbine too quickly, I think it's possible to hit a bottleneck and perhaps there's a cap on how much power it can deliver.

[@martinrasmussen6634]

The answers are in the video; 6:37; Small scale plant; 4MWh at max 2.5MW (62.5%) 6:54: Bigger scale plant; 200MWh at max 20MW (10%) So the true answer is; it all depends on gear used in the steps/design manual.

Also noteworthy is the fact that in planet earth’s history, the greatest appearance of life forms on earth occurred during the Cambrian Age when CO2 levels were so much higher than now.

[@Neuralatrophy]

The tradeoff between this and lithium is the cost of that deficit in round trip efficiency. For stationary storage, size of the installation isn't as important as long as its cost effective. Money, as always, has the final say. With the Co2 storage, parts are common, easily replaced, the medium is regenerated and never wears out.

[@antonnym214]

Nice reporting! Interesting that CO2 can liquify at ambient temps. It's just a matter of pressurizing it. That round-trip efficiency (75-80%) and scalability are surprising. This concept is so simple, one has to wonder why it wasn't done before. All good wishes.

[@psycronizer]

look closer at the diagram, you'll notice that there are two types of energy needed to run this thing, electricity, and hydrocarbons, and there's transition losses going between matter states, this isn't all it's cracked up to be.

[@billbaldwin8074]

Yes. This sounds practical. It could actually work at a quite reasonable cost and scale.

[@Donkeyearsa]

I have seen this reported before except that the storage dome was under pressure by a couple of atmospheres to have more CO2 in a lot smaller volume. They would take a strip mine seal the ground from leakage, give it a roof then have it have around a pressure of about ten or atmospheres.

[@chaslittle9488]

In saskatchewan Canada we have many oilwells that produce an excess of CO2 at the refinery. This is then pumped back into the ground to flush more oil from the deposit. We also have coal fired power station that is fitted with a carbon capture device to reduce CO2 emissions. Only drawback to this system is -40c temps in winter.
