[@Krasbin]

I was about to say the same thing. 70% sounds really promising. I hope that this is a good alternative to hydrogen for long term storage. Batteries (Li ion batteries at least) do not operate well on longer timescales because of their discharge rate.

[@w0ttheh3ll]

@@Krasbin Self discharge is not the problem. Good Lithium Ion batteries lose less than 5% per year. The problem is that it's economically insane to buy a big rechargeable battery and only charge it every couple of weeks or months. With current battery prices, you need to use a battery installation every day if you want to recover your investment.

[@Krasbin]

@@w0ttheh3ll I didn't know that. I thought it was about 1% per day, which when combined with about 90% efficiency would result in 70% (as presented in the video) after about 20 days/3 weeks.

But it would only cost between 5 and 12 cents/kWh for the usage of those batteries. When they become cheaper the cost will of course go down. But its actually possible and financially feasible today.

No worries about clicking away, I love these videos. You are really good at explaining complicated concepts to people. It's nice to see a Canadian company at the forefront of a new technology like A-CAES. Hydrostor's "thermal management system" must be a trade secret of some kind, but if it's comparable to the Chinese system the efficiency must be similar as well. The capability of storing power for days certainly fills a hole in the current market. I wish 'em well. Don't know if this is the case, but it looks like Augwind's technology has the advantage of being upgradable. More capacity could be achieved by burying additional tanks. If they run slowly then they probably store energy for long periods as well. Looks like neither of these companies are going to directly compete against lithium batteries. And of course China is doing everything all at once, as is fitting for a country of such tremendous size. Hopefully they'll feed all this new storage capacity from renewable sources. It really does sound like a promising new technology.

Great content, thanks Dave. I work on the platform tech side of the industry connecting large portfolios of battery and renewable assets for monitoring and optimisation. You're right, Lithium Ion is an an essential but limited grid scale technology. Used mostly for frequency stabilisation, today's grid scale batteries have only a few hours capacity and operating constraints which limit their use. Long duration storage, such as the projects you mention, is a vital missing piece of the puzzle. At the moment in the UK and Europe, grid connection and capacity constraints are a major blocker to storage projects. Part of the solution is likely to be collocation of new long duration storage with existing solar installations. Transmission System Operators (TSOs) are working hard to find solutions to but our infrastructure was not designed for distributed generation and storage so this will take time.

One of the oldest forms of portable energy storage was using compressed air from a trompe, which is basically a gravity powered air compressor, water and air fall down a pipe, are seperated in a chamber far below, and the falling water means that the air in the chamber below is under imense pressure, that air can be captured at that high pressure, or piped to distant air powered engines.

Doesn't sound all that portable, actually.

[@denvera1g1]

@@jpdemer5 you put that high pressure air into a container, i just described the charging station

[@ednalansdowne232]

The trompe requires an exit for the water and so must be located in a hilly or mountainous area where the water source is at a relatively high elevation and is able to discharge from a low elevation. Otherwise energy will have to be expended to pump the water from the level of the separation chamber. One has to look at the relative compressing efficiencies and cost and complexity of the alternatives. The potential energy (of elevation) of the water can be used to drive a water turbine which could drive a compressor, or could be used in a trompe as you say.

One thing I've been wondering when I hear about grid storage solutions, is, for us in the UK, would offshore wind power (specifically floating off shore wind) get to the stage where we can simply oversubscribe it based on it's minimum generating capacity (I believe that's 56%) and shut it down when it's not needed? Or will that be prohibitively expensive?

[@jimurrata6785]

Curtailment is common in renewables, but usually overcapacity is diverted to grid storage or sold to another market through an interconnect cable. Power companies don't like it when a windy day drives market rates into negative numbers

[@janniskoksel6336]

Theoretically your solution is possible, but: 1) floating offshore is still under development so who knows whats gonna happen there 2) wether phenomena are usually 600km in diameter which means thet the transmission capacity in the whole country has to be big enough to support regions where the wind is calm (which changes over time) 3) wind capacity and compressed air storage seam to be relatively equal in cost per MW, so it makes more sense to place storage close to windfarms to get a more stable transmission In the end one just tries to minimise transmission costs (which is quite expensive for reneuable networks)

[@valdisandersons129]

Overbuilding is a necessity with any power source to ensure stability and backups. It’s that with wind and solar it’s needed to a bigger extent. That’s where energy storage and demand side solutions are actively being reaearched and deployed. As @Jim Urrata stated, it’s already an issue in places like Denmark, UK, Ireland etc. Batteries, CAES, pumped hydro, even H2 is actively being looked into and deployed. The more rountrip efficiency you can get from the storage the less overbuilding one needs. The same applies to scale of the storage. What’s good a 99% roundtrip efficiency if you can’t scale it? CAES and especially pumped hydro can be scaled to silly levels even though they have ‘only’ 70-80% roundtrip efficiencies. The other driver for overbuilding of wind and to some extent solar is demand side industrial needs. If you can split water and use the H2 to make ammonia and plastics with a plant that’s designed around the intermittency of the power sources then you also end up with extra capacity that can be diverted to the grid when in a pinch (and the other way around if the chem plant has spare synthesis capacity, minimizing negative electricity prices and curtailment).

[@jimurrata6785]

@@valdisandersons129 Hydrogen is really a boondoggle, except in very specific industrial applications (like ''green' steel and high ISP rockets) Ammonia seems an attractive storage medium for it until you account for the bond strength and hazard to life. I wish I could envision the day when we have such generating overcapacity that industrial scale electrolysis is viable, but I don't have much faith that I will ever see it. That's not to say that we (as a species) should not push ahead with renewables like wind and solar. The other side of that is not viewing 'the plastics crisis' as a tremendous hydrocarbon opportunity. There's a huge amount of hydrogen right there, along with carbon that could be used or sequestered. But... again need lots of energy to break those bonds without creating nasties like dioxins.

I like 2 things about batteries compared to compressed air. 1 No moving parts. 2 Room for improvement. But for longer term storage I think that batteries will remain a too expensive option.

[@tonysu8860]

Consider thermal storage. 1. No moving parts 2. Abundant, cheap materials 3. Based on well known physics used everywhere including in practically every home with basic modern conveniences 4. If low temperature (600 degrees F if Na or NaCl), minimal stress and extremes unlike CAES.

Great content as usual Dave. I am aware of all these concepts. Many will work, but difficult to drive due to the large capital investment, incentive, and will of investors as you note.

Hi Stuart. I am very sorry about this. Something has gone wrong this week. I am tying to sort it out with YT today

[@rainerdeusser]

Let me humbly suggest that we no longer mention that batteries can catch fire. ICE vehicles catch fire far more frequently. Its asymmetric and the framing leads to a general assumption that EV are a hazard, which is not true. After all, in the long run we all die, but it wouldn't do to state that in every conversation.

[@danyoutube7491]

Well it's a drawback, however rare, of that particular technology compared to other battery technology, which is one reason alternatives to liithium ion batteries are sought after. I think it's relevant to mention it, even if some straw-graspers want to use it to have a go at renewables.

[@EleanorPeterson]

Nope. ICE fuel is specifically designed and manufactured to vaporise, catch fire, burn, and explode. Everybody knows it's terribly dangerous stuff. Batteries, on the other hand, are not meant to burn under ANY circumstances, so if/when they do, it represents a catastrophic failure and is a newsworthy event. The siting of Lithium battery energy storage facilities in residential areas is a hugely controversial issue here in Britain. People deserve to know that the supposedly 'green, safe, clean, silent' installation on their doorstep has the potential to catch fire. It probably won't, but it might. Storing millions of gallons of petrol or aviation fuel in the same residential area would never be approved; a battery installation is not without risk, and people should be told so. Jet airliner crashes are inconvenient for a company's reputation and shareholders, too, but they do sometimes happen. When they happen for reasons of incompetence or negligence and hundreds of lives are lost, and then hundreds more are lost in a similar event a few months later, it's unacceptable to avoid mentioning the disasters, even if it upsets share prices and tarnishes a company's name. Pretending battery fires can't or won't happen may make certain people with certain brands of EV sleep more easily at night (and not have any adverse affect on their precious shares and investments), but a battery fire is always a disaster and should not be hushed up.

[@rainerdeusser]

@@danyoutube7491 i think you underestimate the effect of this lack of understanding on the development of policy globally. government policy is affected by political sentiment and petrol dollars skew that sentiment against climate change transformation. the cumulative long-term effect will be devastating. think in terms of compound interest mathematics.

[@shenmisheshou7002]

Maria Helena Braga deserves to be mentioned alongside Goodenough because she has been major contributor to much of his recent work on alkali-metal anodes tech. She was the one that used glass electrolytes which was a key in that development. The next gen battery tech will probably benefit a great deal from her contributions.

Your thoughts on citys reducing there parking lot size by 50% by making parking garages. The new land can be used for green spaces to help cool and protect people from heat flooding and energy demand because its cooler so you cool the building less throughout the day. Oh ya parking garages can have same or more parking spaces and have batteries on first floor and solar or wind on top to reduce energy demands and increase energy storage.

[@EllyCatfox]

Seems kinda like an excuse for lazy city design and continued over-reliance on cars.

[@EllyCatfox]

We should reduce parking lot size by 50% by having 50% fewer cars, more public transit, more bike lanes, and having smaller, more frequent business, residential, and recreational zoning closer together. Suburbs need to be completely restructured, not parking lots. Gotta love these people who have the money to live a nice fat middle class life with big fat bookshelves telling the rest of us that more parking garages are what we need.

The current state of the compressed air to electricity technology would translate to over one thousand facilities spread around the UK. The cost of building will then be £500 thousand million, or so, for one thousand sites. The idea of the stored energy sites would be to reduce the peak time load of the power stations. Generating electricity when needed plus a smaller energy storage system is possibly the way to go. Solar panel orientation should be east and west, as well as north and South to generate electricity when needed. Wonderful presentation as ever, thankyou.

It's 1st Nov 2022, I have notifications for this channel fully enabled, yet the last notification I had from this channel was for "Solar Cooling", around two weeks ago. So I missed out on most recent two. I get a ton of notifications including for channels that I rarely view any more, however I haven't bothered comparing to see if I'm missing notifications from any other channels. I suggest that if YT have nothing to hide that they need to take this issue seriously. It's not as if they can't determine themselves whether notifications aren't going out unless their logging system is sub optimal. Finally, you do great work Dave and I very much enjoyed this video.

Highview Power in the UK uses liquid air energy storage, with captured heat as well. Efficiencies I think are in the 70% range as well. Because liquid air is utilized rather than compressed air, there is much less land use I believe, versus compressed Air energy storage systems.

Rather, cost is the limiting factor and Highview currently beats all competition hands down for the reason you stated; an already existing supply chain of proven technologies.
