I studied civil engineering at uni and remember one amazing statistic from the materials lab... To manufacture 1kg of cement (the bonding material of concrete) creates 25kg of CO2! I cycled past it again in the spring this year (2022) and it was being dismantled.

The big problem with any kind of gravity-based energy storage system is that gravity is just not that strong a force. You need vast masses (which is what hydro starts to get you) or vast heights for the storage to become significant enough to matter. That's why this tower can only handle the approximate energy output from one wind turbine. I've seen other schemes with masses going up a hill on rails and such. If you do the math they just don't have that much capacity. I saw one that involved lifting whole blocks of land from underneath by pumping in some kind of fluid. Still seems overcomplicated but with that one, at least the masses were getting into an impressive range.

We've had pumped-storage hydroelectricity in Norway for years, we usually buy cheap wind power at night times from Denmark to pump water back up.

I feel like people are forgetting the biggest problem with this; what if these tall skinny towers with nothing supporting them, fall? There’s literally no skeleton or anything to hold these in place. If one of these things gets swayed by the wind while being lifted up/down and it knocks the tower, it’s gonna be a super high tower of concrete bricks crashing to the ground followed by 5-6 cranes. That sounds safe!

I can tell you now; the maintenance costs ALONE on this thing would be eye-watering. Anything involved in lifting apparatus has to be replaced after a certain number of cycles, and assuming these things are lifting and lowering blocks nonstop, which they would be, the lifetime of cables, bearings, pulleys, would be, at a guess, less than two years. I reckon just the cost of lubricating that thing would cost around 100k a year, probably more. Upkeep is so often kicked under the rug when they announce these big scams.

Second, the blunder of penny pinching executives: when they’re balancing the sheets for something, they realize they could save on all the upkeep costs by just killing the project, all while forgetting that it often costs time, money, and effort to decommission things. These costs often runs up pretty quick, and overshadow the operating costs; meaning they won’t see the benefits of decommissioning for years. 🤦‍♀

@1998SIMOMEGA Stanford dropout made the company Theranos and proceeded to scam a bunch of investors/patients with promises of a new blood testing methodology that was completely made up. The issue wasn't that they failed to produce a new blood test method. The issue was that long after they'd determined that their new test method was wholly ineffective, they continued to raise/take money from investors, ran tests for patients using their competitor's results, and provide outlooks that contradicted internal knowledge/documents. It's perfectly okay to fail, but it's a crime to hide it from investors.

Pretty dope and concise video. One potential criticism is you do need a source of large body of water as well as a terrain that lets you pump water up and down (dam or mountain). Not all urban communities have the space or geography to accommodate that. So using the underground gantry version of this actually might actually have a justifiable use casa

Or you could use the next version he showed, using water storage underground with tanks on top. This removes the issue of erosion/arranging as water can't erode/break (it is a liquid) and can be moved way easier than concrete (using pumps instead of a crane). This is almost the same as using two offset water storages, minus the location limitation but with added cost of creating an artificial container above the initial lower water storage.

The underground gantry idea on the other hand just requires reinforced walls to retain the dirt/rock- something much easier to find and much cheaper to build.

I have a genius idea on how to make your system even more energy efficient. You can use solar energy to boil water from the lower reservoir, and then you can recondense it in the upper reservoir so that it doesn't need to be pumped. Then when you need additional energy, you can allow the water from the upper reservoir to spin the turbine and dump into the lower reservoir. I call this variation the DumbAss Modification... Or DAM for short.

A concept that I think is pretty cool and maybe could work is using abandoned mines, which can be upwards of a couple kilometers deep, and use sand instead of concrete (the sand could be easily retrieved locally and it's probably already there anyway because they had to build the mine in the first place)

Oh man, we are so screwed if an idea like this can get the funding for even the CGI mock-up, let alone an actual proof of concept.

I wonder if trading a gazillion small blocks for just one big massive lead weight or some other heavy material would be better. Would last longer than stone and weigh more. One big block instead of many, you hoist it up when power is cheap and release it to generate power during the peak times to pay for the cost paid to hoist it earlier hopefully with some profit. Then you have just one big block to lift so there isn't this expensive dancing orchestra of blocks. Just one big one. Goes up and down like once per day. A really big block so tons of energy is sucked down but released later. If you make just one big block I wonder if the pollution it creates to make Is less than if you made many blocks. Could even just be a big bucket built to last long term filled up with dirt even tbh. One big giant bucket would be a better idea because you could fill it up with different things. Could fill it up with some ocean water. A huge bucket. Put it in a rainy area. Idk man. Put springs under it so it reverses direction quicker when it hits the bottom.

I love how I live in Tasmania, a state of Australia that produces more hydroelectric and therefore carbon zero energy per capita every year than any other state, meaning we were closer to 100% clean energy than any other state. But in 2017 the Turnbull government created the NEG, which in short forced our state-owned electricity provider Hydro Tasmania to buy power from privately-owned mainland power companies. These are the same power companies that go all "BROOO TECH BROoo" on us whilst running on mostly coal power. Coal power they're too lazy and greedy to divest themselves of, so I'm forced to use their coal while they use our hydro and wind and solar. So now, I'm forced to buy coal power from a monopoly as I can't afford solar panels for my own home. And as Hydro Tasmania privatisation is on the cards from the state Gutwein government, my power bills are probably going to soar. So now, thanks to tech bros demanding their "fair share" from the federal government and leeching off the taxpayer at great expense, I live in a state that uses 90% carbon zero energy running on coal power for several times the cost.

The issue isn't so much with reclaiming that energy, as there isn't too much in there, compared to the total energy this station could handle over its lifetime. The issue is that half of thr blocks are completely useless, as once half of them are "lowered", there is no potential energy difference between the top rows of both stacks. So essentially, half of the blocks are just used as a spacer.

Another thing with the cranes is the more you use the battery the less energy you actually get back out of it. A block at 100ft is going to net you more energy than a block at 50ft purely due to the height. So unlike traditional batteries and even water systems, the output is going to slowly start diminishing as you use it which makes it unreliable and kinda stupid

I share your scepticism. Although pumped storage requires suitable terrain that doesn't exist in many places. Digging massive holes is harder than it looks and means vehicles working for many years and releasing co2.

The gravity battery as the one shown here has several drawbacks as you just well pointed out. The main advantage is that very small energy is wasted during the loading & unloading cycle and maintenance is simple . They are using abandoned vertical mine shafts now, but still total energy stored is low. The Hydro pumping facilities are a very good solutions, but are expensive to build and maintain.

I would like to see a crane and water-tank version of pump storage in a big pit more thought out though if I'm honest.

You simply don't have that in the middle of a desert, neither you need that kind of a backup; a battery of that capacity could easily serve a town several times as large, which is even rarer in a desert. Also let's do some math: this thing is about 90m high (as much as a 3 MW wind turbine), and the cranes seem to be about 50m across. Pumped water energy storage is about 80% efficient, which adds up neatly: a water tower of the same size as this contraption, with a pool next to it, can store & output almost exactly 35 MWh of energy, while requiring significantly less maintenance and complexity. The amount of water contained in such battery is much less than the people using it spend over a couple months, and it can be any kind of water, including sea water or waste water from the people using such battery.

pumped hydro doesn't work as many places as the crane does. But I agree, build them underground and with a gantry crane. pumps and turbines fail same as concrete blocks, and more often. Also, when dealing with water you corrosion issues, filtration issues, etc. The concrete blocks will last a LONG time and are EASILY replaced. Guess what, EV car batteries, solar panels, and wind turbines also used fossil fuel energy to make as well. This is a bullshit argument. Have to start somewhere. Never mind the fact that concrete is far more recyclable than lithium batteries.

"Pumped storage hydroelectricity". Devastating.

It is astonishing that investors would back this idea. One ratio that is out of whack is the required investment per kWh of energy storage. Cranes are very expensive pieces of machinery. Touchy, sensitive, and requiring great skill to operate and maintain. The video mentions wind, the mortal enemy of tower cranes. The usual rule is that you must shut the crane down before the wind hits 40 mph. The maintenance expense would also prove to be a problem. The ropes wear out and have to be replaced regularly. It’s a big, expensive job every time. The structure also develops fatigue cracks that require expensive repair performed by skilled ironworkers and welders. The “duty cycle” would be equivalent to near constant operation moving the full rated load. Very destructive. Finally, utility-scale capacity would come only with immense outlays. This thing is an expensive toy and a science experiment that will serve to test things that are already known. It’s not cost effective, and this could have been shown on paper without building a thing.

And I was so looking forward for these self building Jenga towers. 😆 BTW, people give wind turbines a lot of criticism for being too noisy. You think a thing like this wouldn't generate sound? Living next to this would be like living next to a permanent construction site!

Also, as we're seeing here in Ontario Canada, pumped hydro projects can get the same type of opposition as wind farms. Some of it pure NIMBY-ism, some of it legitimate concerns about environmental impacts on the local area. As I said, I'm skeptical of energy vault too. I think there are probably ways to make the basic premise of "lifting heavy things as energy storage" more practical than what they're proposing.

The biggest difference between the two is that hydro pump storage would expect lower startup and maintenance costs compared with the tower.

The main problem would be more in tear and wear of grab-release systems and pullies for the blocks rather than the blocks themselves

Its everytime wonderful to see how investors pump their "stupid money" into projects that are apperently dumb.

It's so they can "write off" the "loss" when it "fails" for what they put in, lowering their taxable income, so they aren't hit with the high rates, and get to keep more of their income... and get a huge tax refund in the process.

What we need is to take money out of the angel investors hands and make investment about smaller micro investments then this stupid shit can die in a trash fire and anyone who pulls like a Fyre festival would never see a dime of investment again. Aka I’d never see the word Elon ever again and the word musk would be reserved for books about beavers

Unlike the extremely simple mechanics of a water storage system, Energy Vault relies on multiple complex crane systems all working in complete synchronization. A single point failure would render the entire system inoperable and repair logistics would be measured in days and weeks rather than minutes and hours.

"they look like they would fall apart much sooner" that's some amazing analysis right there. you must be smart.

Thank you for the video. Please consider the following points: 1) The energy efficiency of Pumped-Storage Hydroelectricity (PSH) is less than that of the energy vault. 2) PSH has its own problems related to construction cost and others. 3) I agree with you, the shape of the energy vault tower can be different, however, it is built on the ground rather than below ground to reduce construction costs. 4) The blocks do not have to be made of concrete, they can be made of any material, hence the CO2 emission issue is invalid. 5) With regards to stability, tower cranes are used to build skyscrapers, hence, they can be stable when sufficient anchorage is used. 6) In light of point '5', tower cranes can extend their operational heights, while gantry cranes are limited by their initial design and construction. Thank you again for bringing these matters to mind. Such videos help pin point matters of concern and improve the design.

This made me go from "This block tower idea is pretty interesting" to "this block tower idea is stupid" within minutes. I gotta say, that experience on itself is the most interesting.

@@SebastianA.W. people need to consider implications. Being introduced to a new idea that solves a problem will initially sound good, especially if you are aware of the problem beforehand. This video introduced a solution to a known problem, gave some pros before talking about problems inherent in the solution. The format of the video, including the title and the thumbnail, is making people go from "good idea, why not do that?" to "oh, that's why it's bad". Accusing anyone of being gullible because of this is either being ignorant or being a jerk. This video takes curiosity and teaches to apply critical thinking. It is acting to oppose gullibility. It is educational about the concept by using a real life example. The whole thing is too well done for the video to simply be about the energy storage via gravitational potential energy instead of electric potential.

I once thought water towers could act the same way and then an engineering friend looked into it and he basically said batteries are already better so I dropped the idea.

Well I mean they do and they don't sure a battery can hold a larger charge for cheaper but said battery ages so it needs replacing and also that is without mentioning location and temperature. Any and all batteries don't like cold or hot (well except for some exotic batteries but those haven't reached real production yet) or even better is that it allows for amplification of local hills and valleys making what would be a mediocre hydroelectric battery into actually worthwhile. Sadly though while their maintenance at least long term looking at current battery technology modern electric pumps are really really efficient at what they do meaning there is little room for the tech to improve in a meaningful way unlike batteries. They do still have uses even then though!

It does work if you make the reservoir large enough, pumped hydro works very well as grid storage but it requires specific terrain to set up.

@deusexaethera

Batteries are not better than water towers, because water towers have already been built in large quantities. Your engineering friend didn't consider all the variables.

I have two gripes with this dismissal. One, digging holes costs a lot of money and with current excavation technology it generates more CO2 in the process. Two, with the first point in mind for pumped hydro to work economically you need a conveniently naturally occurring hight difference that is easily accessable and a nearby connection to the grid. This is almost never the case. A gantry style crane in a warehouse like enclosure would eliminate most of the problems with the current Energy Vault like design while still being (at least relatively so for gravity storage designs) low cost to build and accessible anywhere there is open land. Your synopsis of the idea was very concise and easy to understand. Thank you for bringing more awareness to the problem of renewable energy peaks and your contribution of how to address the problem. If more creators provide responsible and beneficial content like you are now, we will be one large step closer to bringing a sustainable future to us, those across the world, and those who are yet to be brough into it. I hope that it can be better and more peaceful than the one we live in today.

Water pump system only works on places with much water. A solution for areas without much water would be also good

You know they can import Water right

Yet another point you didn't consider: This concept only ever makes sense if there is any actual height difference between your blocks. And the less height difference there is, the less energy you can extract. So your "empty" situation basically is all blocks at the same level (so you _could_ replace the "inner" block up to that level simply with a solid foundation), and the lower your storage goes the less efficient your system becomes (because you have constant time attach/detach operations -> the lower your delta goes the higher your waste). And lets not even talk about the crane arms travelling empty half of the time.

@@pwnmeisterage A good point. And there is another issue with the cranes which i haven't seen mentioned so far (unless I am missing part of the point OP is making) Not only is attaching and detaching wasting time, but the whole lifting process is - the higher the tower gets, the worse the problem becomes (part of the reason why it takes so long to load and unload container vessels). The further a crane needs to travel - both up and down and side to side - the more time it takes. Therefore it has not only a limited energy output capacity, but the energy intake capacity is similarly limited.

"6 would see 5 in action" Make that 4, I think. Because it looks like the cranes are supposed to serve as counterweights for each other, and a big crane without a counterweight is bad news.

I had a different version of this idea years ago and came to the same conclusion. Water would be less efficient but makes up for it by being more reliable, less cost, and more versatile.
