WORLD RECORD energy tech displacing lithium ion!
ฝัง
- เผยแพร่เมื่อ 29 ต.ค. 2022
- Lithium ion batteries have been the mainstay of the energy storage market for decades. But with utility scale energy storage projected to skyrocket to 2.5 terawatts by 2040, grid operators are frantically looking for cheaper, more reliable and more environmentally friendly alternatives. Now an 'old' energy storage technology has been revitalised and revolutionised for the 21st century. And as usual, the race is on between China and the USA to gain market dominance.

The amazing inventor Jonathan Goodenough is also a WW2 vet, who served as a meteorologist and calculated, among many other things, the weather on D Day. It seems he was more than pretty good at it too!
sounds good enough to me.
@@drury2d8 badum tuss!
Amazing man and thanks for that fact on WW 2
I’m happy to know we have some absolutely amazing people in this world. I hope we can be more like them.
he's a nazi who was given the name
My head is programmed to check every Sunday evening 😁
Go for the trifecta: bury the air storage tanks underground, put the solar panels to charge them seven meters in the air on single axis trackers, and grow agrivoltaic-friendly crops underneath. That's using the same patch of ground three ways, that's a win no matter how you slice it.
Cant imagine thats feasible; the wind loading 7m in the air would be significantly higher, and its effect would be amplified with a larger moment arm.
You could always breed giraffes...
And make it an eolic solar combo.
@@redstarsrbija Steel is fairly cheap. Solar panels are very light. So far, they have stayed on my roof with high wind gusts. Low light crops can be grown under them Sale of crops will pay for the steel within 2 years.
@@elizabethbrown3135 Stick with baking cookies!
Regarding the plant in China, I would like to have multiple outside sources to verify this plants claims. China has a severe issue with companies falsifying data in order to get funding or simply for propaganda purposes.
70% efficiency is really promising. I didn't know CAES can get anywhere near that.
If these facilities can be built cheaply, that's a huge step towards solving the storage problem.
Thanks for the video!
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.
@@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.
@@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 that knowledge is from about 10 years ago, and I would like to update that. Do you have a source (not a link, TH-cam doesn't like that, but some name/title of an interesting video/document?
@@w0ttheh3ll Yes, you have to use it every day. And when you do that you can - with todays products - solve the battery problem easily.
Ok, not easily you would have to scale the battery production facilities about 1000 times. And it would cost trillions. Literally.
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.
I used Tesla Megapacks in my "back of the napkin" calculation. Only one problem, we would have to make Elon the richest person on the world... Oh thats already been done. Then whats the problem?
30% losses would mean 100 Terawatthours a year for our small country. LOSSES! That is NOT acceptable.
The US uses currently 28.5 PWh - Thats Petawatthours primal energy. Lets say the US could get this down to 50% then its 14 PWH and 30% losses would be 2.9 PWH.
That would mean the US have as much LOSSES as the whole of Europe USES IN TOTAL!
THAT IS NOT ACCEPTABLE SIR!
I'm a material scientist. My recent work has been mostly in spintronic materials for more efficient computation and data storage, but what I love about the state of energy technology right now is how many companies and government programs are trying every conceivable solution. I doubt we'll find a magic bullet technology that changes everything overnight, but rather I expect many of these solutions will have small, but significant advantages over current technologies, and many of them will find niche applications. We'll see slow, but steady improvements in energy storage over he next couple of decades. I just hope the rate of improvement is sufficient to stem the most apocalyptic fears of climate change.
Your videos are no longer free of ads. there were at least two breaks for them during the show
Yes, I had two ad “breaks” too
Same here
Same here but I didn't mind.
Yes, something has gone wrong this week. I am trying to rectify it with YT.
It would be nice to see a comparison of all the grid-scale energy storage solutions, their capacity, efficiency, responsiveness, cost/MWh, max input/output vs investment.
P.s. I got adverts too, but notifications work fine
I second that
Yes, ads here too
I got a few a ads while watching.
Still knocking out great content Dave. Really professionally done and giving hope to your thousands of subscribers. Well done sir!

@@JustHaveaThink Hi Dave! Regarding your request of evidence for TH-cam I checked my status on the bell and found it is off. I'm 99% certain it was on. I rang it again just now, will watch it for you.
Edit: typo.
Glad to have another video on compressed air energy storage systems. For a second there I was worried this was going to be yet another "revolutionary alternate battery chemistry about to change everything" video. Pleasantly surprised on an update on the important compressed air energy technology family.
Indeed, every week theres a new "revolutionary new battery" and nothing ever seems to come of it.
@@2MeterLP yeah, like cold fusion is always "just a few years" away.
Help me understand why the Canadian system, for example, needs the compressed air part of the system.
Surely pumping water up and running water turbines (as Dinorwic) on release cuts out the heat issue altogether and reduces the complexity of the system.
@@stevewilliams2498 pumped hydro is simpler and more efficient, but has more time, space, water, initial investment, and geographic requirements than compressed air does. Both are important systems and should be used when optimal for a specific system.
Don't have the link. Compressed air and kevlar "balloons". Backyard size system.
i never hit the bell for any of the channels i subscribe to, and yet I always see your videos in my subscriptions.
same
Same here. I don't like notifications of many kinds. I'll look if i have time. :)
Longevity is key for these projects to be viable
Are you talking compressed air storage or John Goodenough 🙂
@@nickcook2714 Yes ! 😁
I would be surprised if Any of these installations have an operational life of less than 50 years, and I envisage many will be in use for double that, as long as the need is still there.
I just stumbled on this video though I have the notification switched on I did not get any notification for this. Wonder ho many I have missed. I really like watchiing your videos as they give a neutral and factual representation of the technology being in the subject.
Thanks Venkatesh. I publish a video every Sunday, so it sounds like you may have missed quite a few!
Hi David. Great content again, as I get every week but I normally follow the link from the patron email and watch your video before the TH-cam notification can arrive. I did receive a TH-cam notification this week but I probably have missed seeing then recently but maybe this is just because I have watched your video before they are sent out? Please keep up the good work! My grandchildren need people like you!
Something similar is being done in Italy by a company called Energy Dome. Instead of using air, they use compressed CO2. The drawback is that you need a big storage space (the dome) to store the uncompressed CO2. The advantage is that CO2 compressed is liquid so it can be compressed in an even smaller volume. They also have heat recovery
I had the "not being notified" problem in the past with other channels but it hasn't failed me with this channel yet.
Thank you for your positive attitude in times of some gloom.Society needs to stick together to produce the answers to solve the problems?
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.
The World need to move a lot faster, there is no time to wait another 2-3 years.
About what? Nuclear fallout?
Imagine you're on an iceberg drifting south to the equator and you're trying to invent refrigeration for icebergs drifting south to the equator.
@@peacepoet1947 collapse of earth's system? I guess
If only 2-3 years...
You're not wrong there, and we're going to be struggling to stay within 3 deg globally even with that level of action.
It's not too dissimilar to the Highview Power storage facility planned for Manchester
Do both. We need both solutions. They will complent each other.
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.
@@jpdemer5 you put that high pressure air into a container, i just described the charging station
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.
@@ednalansdowne232 This is why i say oldest forms, because it pre-dates the ability to manufacture turbines or piston compressors. it is dead simple, which is why the design is so old.
Dear Dave, aside from hardly receiving notifications I now have to experience ads being inserted, although your channel is supposed to ad free and has been so in the past! Thank you, anyway, for your invaluable work for this channel!

Man I LOVE this channel!
Very worthwhile to see if these limited resources can be replaced. Thanks for keeping us informed!
Notifs broke for me around 2 months ago, only watched 2 of the last 8 episodes when i specifically hunted down your channel to see that weeks video. This was the first notif I've had in ages.

Got a reply from a whatsapp user that definitely does NOT seem legit though he uses your logo (see th-cam.com/channels/AX8u6KHHI4_05lZiP7vONg.html ) replying to this message. Suggest you report it. Seems an odd response and not from your main account.
Thank you for the video! I typically check my subscribed section and find your videos there without any notifications.
I hope this channel grows to 1M+ subs asap
Thank you. I hope so too!
Well done Dave. Another excellent presentation!
Many thanks!
technology is not an obstacle, politicians are.
Your not the only channel that is having problems with notifications.
I wasn’t subscribed to your channel until today.
But for some reason TH-cam is offering me old videos that I have already watched and literally have a like on them.
To go from 30% to over 70% in forty years is not bad going. I wonder how scalable these plants are? The Li-ion storage systems are modular and can be easy to scale up : simply plug in more battery banks (up to the capacity of your grid connection)
P.S. very good explanation of basic thermodynamics. It's always nice to hear and able communicator explain things well.
Sounds quite promising. Oddly enough, this is the first I've heard of it.
BTW, got the notification for this video, but don't remember seeing previous ones recently.
Thank you for another great video. I got my notification as per usual.
Awesome! Thank you!
Would be interesting to compare the costs to that of cryogenic air storage such as employed by Highview Power. Lower pressure systems tend to be cheaper to build.
I'm no engineer, but liquid air battery seemed far simpler and presumably far cheaper, not to mention mature 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.
Again, great content, thanks.
Cheers Tim.
There's one thing that I've learned in my 76 years on this planet that is anything mechanical wears down.
One technology I would prefer is the AMBRI battery developed by MIT professor Donald Sadoway.

I have not got a notification from you for a long time - then suddenly this video pups up....thank you for your great work!!!

This seems quite promising. Simple enough to implement.
My preference is for using the phase change of a gas e.g. CO2. I think there was a video about this here recently.

Love your videos, and yes, they dropped off my notifications queue for a while, even though I fully rang the notification bell. Hoping you got that fixed with TH-cam management. Anyway, I'm verrrry appreciative of your clean energy videos. It gives me hope.
Thanks James
This is the first of your vids to come onto my screen for 3-4 weeks. Sorry I haven't thought to look you up. Keep doing your great work
This is amazing - 70% efficiency - If we don’t come up with any more breakthroughs (which is extremely unlikely) we already have the storage solutions we need for a green future - but let keep going!
CATL Prussian White Sodium Ion batteries are 95-98% efficient. 10,000 cycle life, so should last decades even if you fully cycle them multiple times a day. Made with only abundant materials such as sodium from sea salt.
They're already on the market, it's just a matter of time while they ramp up production.
@@antontaylor4530 That sounds too good to be true Anton, but I hope you're right!
@@willm5814 Do a search for "CATL Sodium Ion".
It's good to be skeptical, will. A lot of stuff you hear about on the Internet is vaporware.
Edit - they're not perfect, Will. They take up more room than lithium ion batteries for example, so won't be a great replacement in vehicles or phones/laptops, for example.
However, for grid storage or a powerwall... 👍
@@antontaylor4530 I will (again) - good point, and grid storage is the key to making wind and solar work!
@@willm5814 You know, Will, Britain already has about 25GW of wind turbines. The UK uses about 808GWh of electricity a day, which averages to about 33GW (it's less at night, more during the day, obviously).
Yet wind power is only providing 23.2% of our power, when it could clearly be providing far, far more than that - we need grid storage ASAP. We could probably already go 90% carbon free (wind, solar, hydro and nuclear) with what already exists if we just had grid storage.
And another 12GW of offshore wind would cost less than Hinckley Point C (3.2GW) which would probably be enough to make us 100% wind powered, a bit like our government of late.
Just for clarity, the MWs and GWs of the chinese poject prospects at the end of the video refer to MWh and GWhs yes? 'Cause I'm pretty sure energy storage is counted in watt hours and not just watts.
Well, let's say both (in term of power - kW - and energy stored - kWh -). But the question is valid.. how much energy is stored?
SI would use watt seconds a. k. a. joules.
Hello David. Yes I too have been missing out on the notifications. It was only last week that I thought of your channel and double checked that I was still subscribed and yes I was/am. Let's hope YT can sort this. Even if they don't, you are unforgettable, and I will have my dose of catch up every now and then. Please continue with the wonderful work you do, it is excellently communicated, thought provoking and very appreciated, muchas gracias, sir.
Thank you Raj. I really appreciate your feedback. All the best. Dave
Probably the most significant advance in power generation since the development of Hydro-electric technology. Very, very exciting development. This is certainly the future of clean, efficient and reliable energy generation. Great video, thanks, always something new to watch on your Chanel.
Thanks for yet another excellent video. I am pretty sure Compressed Air storage will be complementary to Li-ion batteries rather than areplacement, since the main problem solved is large scale, low cost, utility/grid scale storage, however not necessarily with the reaction time of chemical/battery storage. In addition, Li-ion batteries can be deployed anywhere, rapidly, compared to Compressed Air or Pumped Hydro storage
Would be interested in the energy density of CAES systems, but in theory a CAES system is competitive subject to the known limits of building a container strong enough to contain the pressure. So, is it a certainty that CAES can't compete with Li-ion in energy density?
Nice video Dave, 70% energy recovery with compressed air is impressive indeed and will make if hard to hydrogen to compete. Offshore wind and oil platforms in deep water (say 6000 ft) would have great potential for storing compressed are on the ocean floor with low cost vessels. Hope all the mechanical issues of rotating machinery and piping can be done economically. Impressive to see the development taking off.
We need to be thinking about how to make money serve our needs vs us being artificially constrained by what money “needs”. I mean, we didn’t wait around until tanks became “affordable” before building them to fight WWII.
Among many others, Robert Hockett is good on thinking about how money can work for us versus against us. Ditto Rohan Gray.
I get notifications intermittently although I was notified of this and the last video
As to this week's edition...super. Thanks
You are correct. I have not received notifications of your new uploads, but this video was on the side as a suggested video.
Hi David. I am not getting notifications either. Very sad about that. Your programs continue to be as well produced and delivered as ever. I hope to have our vision of producing hydrogen from the syngas generated by a biochar plant featured on JHAT some day. Thank you!
Have you tried to usubscribeing and resubscribing and turning on notifications again? Just curious if that will work, have to wait a week to find out.
Another great video. I’m a bit surprised with the 70% battery cycle efficiency with heat integrated compressed air storage systems. If it’s true, the thousands of steam turbines and gas turbines operating at ~30% net heat to power efficiency in LNG and Steam cracker compressor drives, should be able to double their efficiencies. Perhaps instead of direct électrisation, we should consider compressed air/motor hybrid drives to eliminate steam/fuel with much better renewables flexibility. The World’s first trillionnaire is probably already working this….
Previous to today I was not getting notifications, but one did pop up for this video.
I'm not getting them...
I'm curious if folks can confirm that TH-cam app notifications are enabled in the app settings. For example, I'd previously enabled notifications when using my laptop, but I never enabled notifications in the TH-cam app on my phone, so I never got phone notifications. I had to enable the TH-cam app notifications in my phone's settings.
Have become a fan of your channel.
We became fans/subscribers of JHAT after watching one video a couple of years ago. :-) They show up here (Oregon, US Pacific time) on Sunday mornings so we watch then. We don't seem to have the option of a Notification bell, but we don't need it. Love your videos - thank you so much!
Love this channel. Brilliant! 😃
Interesting - thanks for the update
Big fan of compressed gases.
I laughed much harder than I should have. Comments like these... 😂👌
If this works, it will provide a large reduction in the demand for lithium from the largest lithium consumers, allowing lithium's primary use be in small portable devices. This would provide a useful cost reduction in many personal and medical devices.
Air batteries won't work for cars. They're a grid-level storage solution. Cars use a lot of Li-ion cells.
@@incognitotorpedo42 "Cars use a lot of Li-ion cells." - currently (pardon the pun), but there are other concepts in the intellectual pipelines.
My understanding is there's still an economic case for grid-scale storage using lithium batteries with retention times below eight hours or so. These compressed air facilities are big and relatively slow, which makes sense for longer term storage of electricity.
Very cool, thanks for sharing.
Great content! Thank you!

Another wonderful intelligent, well researched and thought provoking episode, thank you. 👍
True but these could be above ground and even stacked in a modular way to maximize space use.
I always enjoy your informative videos and this one is no exception. Keep up the very good work.
This news channel is possibly the single best use of my time of any. It is superb in its asking the really significant questions. It is superb in giving sufficiently detailed science to be easily absorbed and providing the necessary terminology to allow deeper engagement afterwards. A very nice balancing act.
These are beautifully crafted pieces. I would urge every science teacher to mandate viewing.
Hi David.. yes been subscribed for years but notifications have stopped until today.. also pesky advertising has now started.. brilliant and concise video we have come to expect and cherish. Keep up the great work. Nick W
AdBlock Pro works wonders on my Firefox browser.
Yes I use that in Google chrome also, but I used to use David's dedicated App. But that packed up months ago..Hey ho there's always a way around though..😁
Thanks Nick. Loads of people got ads this week. No idea why :-(. I'm trying to resolve the issue with YT today.
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. I believe the key to energy storage is effective, affordable, and Integratable heat storage capability. This will be key technology in the future.
I can't help thinking modular flow batteries will be more practical. Hopefully there will be some new developments.
Humans create money out of our ability to think numerically. We really need to think about making money (our own invention) work for us vs being seen as some sort of natural impediment we can’t do anything about
I absolutely love this channel. Great information every week
Dave! I can't remember ever getting a notification for your channel despite being a subscriber for a long time and having watched many of your excellent media! 👌
If you disable your watch history, TH-cam works exactly like expected. I get ALL videos ALWAYS in my subscriber list. Never misses a beat since then. Notifications also work.
Top tip. Thanks!
I'm gonna try that one out.

unfortunately the world has fallen asleep. thank you for this video.
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.
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.
@@tonysu8860 Good point. Thermal storage is great. But how to do it without moving parts? Pumps, blowers, valves etc..
like the way you make your presentations....thanks so much..
Exciting and excellent information!
How are Highview's Liquid air battery project going and how do they compare?
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?
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
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)
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).
@@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 guess it just depends whether it's cheaper to build a windfarm or an equivalent storage facilty multilied by its efficiency.
Great content as usual and I did receive a TH-cam notification earlier today. HOWEVER, I experienced no less than 3 adverts during your video - this was not expected!!
Apologies for this pedawes. Something went wrong this week. I'm trying to resolve it with YT today
Can confirm this video wasn't notified in my phone as would usually happen - showed up midweek in my desktop front page and, on the first playthrough, 4 ads were snuck in \m/
Can you use old coal mines as storage facilities?
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.
I gave up on you tube notifications a long time ago. Don’t be fooled that your program is add free, you tube managed to slip two commercial breaks in while I viewed this. Although it’s worth it for viewing your great content
Very interesting and informative. Thanks
Really the downside to the Western model of climate investment in this video. China directly invests as a country, whereas our governments sit on their laurals while companies have to come up with economic reasons for investing in climate change technologies. It's the reason there's no hope! :)
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.
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.
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.
@@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.
Thank you for your interesting insights, I very rarely get notification of your weekly videos. Fortunately I do look for them anyway!
👆🏻Send me a direct message right away 🌺🍀
Thanks Dave, another great presentation. I’ve not been getting any notifications and watching tonight there were ads before & during, so something appears to be going awry.
Hi Stuart. I am very sorry about this. Something has gone wrong this week. I am tying to sort it out with YT today
I wonder if you could combine this technology with a carbon capture technology. Since it already pumps great quantity of air, it might be possible to filter out CO2 as well. Rendering the process even more lucrative. No idea if it is technically feasible but I'm just having a think you know...
I am getting notifications, but from today getting advertising in the video. 2 in this clip. Thanks Dave for your efforts. Look forward to your video every week. Cheers
Thanks for letting me know Mike. Ads shouldn't be happening because I have monetisation switched off. I will take this up with YT
Never thought I'd be thrilled over a bunch of… hot air! 😂
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.
Seems kinda like an excuse for lazy city design and continued over-reliance on cars.
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.
Using fewer cars would be better, but yes. No more surface parking.
Sorry, I'm like, a total bitch today. ;_;
@@EllyTaliesinBingle yes less cars good but until that happens why not release the land from its concrete prison and green it up.
*CONGRATULATIONS GOODENOUGH* on making 100 - you are a legend
Beautifully presented, perfectly spoken. This can be used as a master class in videography.

Yes John, you certainly are Good enough! Thank you!
Good stuff. It will a take a variety of different technologies to get things up to snuff.
I don't have notifications turned on. But I noticed this week that TH-cam is slipping in advertising where they didn't before. By the way, I really enjoy your great videos.
A few people have mentioned that ads are slipping in. I will try to stop this happening
No and sporadic notifications from you for a couple of months. Thank you for your work too.
I have experienced that issue with several TH-cam channels that I have subscribed and had notifications turned on for.
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.
Thank you Dear Thinker.
