Organic Redox Flow Batteries - The true path to grid scale energy storage?
ฝัง
- เผยแพร่เมื่อ 7 พ.ย. 2020
- Redox Flow batteries are already being installed on grid systems in some parts of the world. They are a great renewable technology but they use rare and expensive metals and toxic liquids. Now an all organic version has been developed by a team of researchers in Sweden. Could this be the system that finally makes global grid scale storage a reality?

Excellent channel:
1. Science-based information
2. Excellent cinematography
3. Excellent presentation
Wow, thanks! Much appreciated :-)

Thanks for another great video David! 👍🏼😊
Yep no feelings here, just the facts and objectivity delivered in a calm intelligent manner! I love it!

Yes that gave me a double take also!
The Australian company Redflow deserve a mention also. They’ve been manufacturing residential and off-grid scale Zinc-Bromide redox flow batteries for years.
Redox batteries are a natural fit of static, residential applications & far more appropriate to households than the current lithium ion technology.

Jesus Has Arrived Today
Coincidence?! I think not!
This is a joke btw, don't take it seriously.
@John Baxter The govt is made up of representatives of the people. It's your job to tell govt what you want by voting for those who seem to represent best your position, it' snot govt's job to tell you anything.
No one needs MSM anymore, why demand this be put on terrestrial TV or something when it's already available for us to watch here as and when we choose?
@@PinataOblongata I strongly disagree that nobody needs MSM any more! The opposite is true - we need it more than ever. We need news that has an editor that fact checks output, that is balanced so reaches the widest audience and that is trusted because it is known to be accurate. Many "news" channels are extremely biased and are designed to present an extreme view whilst rubbishing the opposite view. Using the BBC as an example, it was once widely trusted but it was in the interests of commercial interests to attack that massive market ownership by creating distrust, so Rupert Murdoch's organs have done that for decades - The Times, the Sun, Sky News etc - and have been joined by ITN to some extent because it is in their interests. The Conservative Party have long been frustrated by not having news biased in their favour - it was genuinely neutral, I believe, so they have been de-funding it massively for a very long time so that it a) is becoming less well researched, b) less global, c) less independent. It has always been slightly biased towards the status quo and to the Establishment, and this cutting of budgets makes that more necessary if it is to survive, to the detriment of us all. So the trend is towards bias, away from independence, and disparaging MSM increases that trend. "Independent" news needs and angle to get a following, so we get bias
@@Neilhuny You've described the entire reason MSM can't work the way you want it to. It's either commercial, in which case there are vested interests guiding content, or its government-funded, in which case there is only so much anti-govt content (even if it's true) they can get away with. And then there's the competition between what's true and what sexy. MSM will never be able to offer independent news because the incentives are not aligned that way.
What we really need is an education system that will produce a populace who can think critically, seek their own information and correctly discern which of that info is credible and backed with robust enough evidence to support it. Unfortunately, govt has already ruined people's education to the point they are failing to vote for those who value education and the problem spirals.
It is worth noting that the redox batteries have two defining parts. First is the amount of current the cell in the middle cell can produce, that is dependant upon its size and how quickly you pump the fluids. Second, the amount of energy it can store is limited only by the size of the tanks. Cool Eh! There are other chemistries to, the most attractive being based on Iron rather than Vanadium. Love it..
P.S. love these vids too, top shelf!
He's back ! Sunday tech nerding out requirement met.
Flow batteries have always been seen as the poorer cousin of lithium type batteries so this new breakthrough is just what the world needs right now.
If as they claim they've cracked the environmental issue of some of the old flow batteries combined with even cheaper construction then it may be time for even people like Tesla to have a rethink.
When there is a struggle to find enough lithium cells to build electric cars quick enough for demand and the future aim of replacing all combustion cars, then freeing up resources by going flow battery for large storage systems makes undeniable sense.
Maybe now we will see forward thinking Grid operators set up flow battery storage at every substation (over 400,000 in the UK) to create the most secure electricity system ever provided.
Exciting, isn't it! I think these new batteries will be revolutionary for mid and large-scale energy storage systems. I don't see them overtaking lithium in the small electronics sector, though.
@@waylonk2453 Quite agree flow batteries are for storage setup no smaller than a house where space and weight isn't an issue.
It's all about finding the right solution's' for the different scales of energy storage. Also sometimes compromising a bit to better use the resources available to us. A Tesla Powerwall will out perform a flow battery but if the flow version is 'good enough' then save the lithium cells for cars where the options aren't so great. People blind themselves sometimes of all the options open to them by the desire for best efficiency or power output.
Much less 'cool' but the largest battery in the world is a redox flow battery so they are not being ignored. that's the 800MWh Dalien VFB in Dalien, China.
Cheers Helen. I agree with you about the roll out - one of these at every substation would be spot on.
Tesla is very much on top of battery technology. They follow every company on the planet that has potentially useful battery technology, and have a number of battery experts on staff. If redox flow batteries were soon going to be capable of beating the best lithium ion batteries on a price/performance basis, I think Tesla would already be working with them. The price/performance specs that the USC team mentioned for their flow battery have already been beaten by Tesla's current best technology.
What I really like about this channel is the focus on affordable, efficient power storage systems. Too many green energy advocates do not consider the necessity of this technology to make wind and solar useable.
Specifically as it compares to "cheap" oil. If solar had some up as the energy solution prior to the discovery of oil and was driving electrification it probably would have won out. Imagine huge molten salt turbines in the 1850s o.o
@NihlusGreen Pretty much. California already has a grid scale problem that on some days they have to discard green energy produced because there's no place to store it or send it. They then have to use fossil sources to meet the demand when the green energy sources cannot due to darkness or lack of wind. The grid requires a constant source of electricity, and every amp produced is immediately consumed. Variable sources like wind and solar cannot be the primary source of power for a grid without some kind of storage medium.
@NihlusGreen absolutely, and from what I've heard, on some days you're generating more than 100%, which is wasted without a storage solution.
@@Andrew-ep4kw or... NUCLEAR!!!
@@jjackandbrian5624 yeah, nuclear power is a completely carbon free energy source that could be an excellent way of balancing out the system. It also has a stellar safety record, even with the accidents.
I have had my eye on Redox Flow batteries for quite a while as the advantages and life of this technology is exceptional, but I really have not seen much offered for a home system in the USA. Glad that some issues are being overcome providing a path to commercial availability of this energy storage system for home use.
"It is considered possible that flow cells based on lignin will in future have storage costs of approx. 3 ct / kWh with a storage efficiency of 90%." (German Wikipedia translated). The potential of this technology is just mindblowing.
Brilliant absolutely brilliant.thanks for that.
Always excellent content without clickbait techniques.
Yet another exciting development in grid scale energy storage. I traveled thru the U.S. state of Kansas in the Great Plains recently and was very encouraged to see many wind turbine farms as well as train loads of blades and pylon sections for additional installations. The plains are very windy with much more potential for wind turbines especially if grid scale energy storage becomes available. I'm also glad to report we will be rejoining the community of nations in Paris Climate Accord with the new administration in January.
All great news :-)
This is a tremendously promising technology. Thank you for putting it into layman's terms for us!
Especially because we need to preserve specific minerals for other battery types. All that competition is already starting to lead to higher prices, which makes the renewable benefit math harder.

Another fabulous episode, well researched.
I actually just completed a research project developing a material for use in an organic redox flow battery. Great video
Fantastic!! Good on you Benjamin. I hope that proves successful :-)
ESS in Wilsonville, Oregon is also working on a organic version of this system using iron and salt water.
Ah, flow batteries! My prayers were answered, thank you!
Superb video
Great video Dave. I've been following this technology for several years and it always seemed to me to be one of the best options for long-term grid storage. I'm glad to hear of the advances out of southern CA and Sweden. Small note, it is 'southern CA' not 'south CA' ;-).
Battery chemistry is becoming quite the rockstar phenom no one would have predicted 10 or 20 years ago.
actually LOTS of people predicted it , Big MONEY from OIL like Texaco did too. They(big oil) promptly bought everything patented and then shelved it or made it unattainable or licensed it for purposes that were ineffective.

@@-LightningRod- The stuff today is not what you are talking about.
@@bongobrandy6297 True, but the delay in reasonable batteries almost 30 years ago (1st Ovonics patent theft by Exxon-MObile & GM) delayed demand, which delayed further research. If Tesla hadn't used "laptop" Lithium batteries in their cars, we would never have jumped the gap to EVs.

I seem to recall a redox style battery that was being tested a couple of years ago . I think it involved potatoes at some point. It could fit in a 20ft container and was completely non toxic.
Great video, so clearly explained as always. Just for info(not criticism) Linköping is pronounced "Linshoping". Not quite correct but easily understood by locals😊

It's not quite right, but also not completely false. (I live in Linköping, btw, and was very surprised and happy that this is where this happened.)
Conductive plastics has been a field of interest for some time. Its nice to see some commercial applications.
Subscribers constantly rising. Well deserved 👍👏
Thank you so much 😀
ESS is a company based in Portland OR that has an Iron flow battery that I have been watching. So far it seems like Li-Ion is still cheaper because of the economies of scale from being in high production but flow batteries should be better suited for the grid.
This Organic Redox Flow Batterie Producer -> www.cmblu.de/en/home/ is using a Lignin based waste product from the paper industry...
When I was in the Air Force I worked on radios designed to talk UHF around the world. These radios have a directional antenna system. They are also extremely large antennas, about size of a fighter jet. The thing about them that always amazed me was that pointing and tuning of the antenna was powered by DC motors, about the size of a double “D” cell flashlight. They would be screaming away, but through reduction gears the antenna would hardly move. This enabled extremely fine resolution with the tuning circuits. Ever since I watched a video on dead weight power systems, I have imagined those DC motors and gear reduction could work lifting dead weights. That was 10 years ago, but nobody is talking about using them. Is there a major reason prohibiting dead weight power systems?
Hi Delton. They are definitely in development. Now called gravity storage systems.
there's also pumped water energy storage, which also uses gravitational potential energy and is i think the cheapest form of energy storage per watt hour for grid scale electricity
great concept. awesome video. waiting for future videos about it, when significant improvements are achieved!
thank you for providing the research paper link!!!!!!
I just want to say that I have just found this channel and it is absolutely fantastic. I am a degree apprentice working in the utilities sector in the UK and so passionate about green energy, but struggling to find media sources to do further research - until now!
This channel is absolutely perfect, I have already binged so many videos and learnt so much!
Keep it up and your presentation style is so good, good on you!
Redflow from Australia have Zinc Bromine batteries available now.
We should continue to aim for 1.5 C. Lovely technology update enabling renewably powered electricity to be dispatchable. Thank you!
We passed 1.5 for the first time years ago. 1.5 isn't a reasonable target anymore. 2 degrees is looking increasingly unlikely given that the land has already passed that and we're waiting for the ocean to catch up.
Now just avoiding complete disaster is all we can hope for.
Solar is already highly dispatchable.
I should add this channel is typically excellent
Another technology to look at is the plating battery. One such is the ZnBr battery. While charging it plates Zn on to thin plates of plastic dosed with carbon to make them conductive. While power is being used, the Zn goes back into solution. The Br released while charging is absorbed by a fluid that stores it. They are only 75% efficient but have a virtually infinite life time with, possibly the occasional replacement of a pump. Another disadvantage is that they must be fully discharged every 3 days but on the other hand they can be fully charged and fully discharged with no damage. There is a company in Aus that is making them commercially.
That sounds like a Frankenstein monster stitched together from the worst aspects of regular bateries an fuel cells.
Utterly fascinating over North America November 10, 2020. It's -3.3 degrees south of California (New Mexico ?) and 8 to 16 degrees between Lake Huron & the south tip of James Bay (which is the southermost extent of the Arctic Ocean). It looked to me that a huge anti-cyclone in the north Atlantic Ocean (about half the northern ocean big) centred west of Spain, due south of Iceland, 6 days ago "pulled" the Pacific surface air straight as a die across North America, cutting off all of the usual Arctic cold air intrusion, warming at north Lake Huron from the prior -3 degrees to 17 degrees over 6 days, then as this huge anti-cyclone moved west into western North America it "pulled" the surface air from about west Mexico northeast up to Newfoundland and up to Svalbard by November 10th, forcing a long tongue of Arctic cold air to intrude down to its tip in New Mexico. Super Wonky but with the cold intrusion down western North America instead of eastern North America for a change. I think it was that huge anti-cyclone in the north Atlantic Ocean that did it.
Thank you for all your work on this channel, I enjoy it very much. I especially liked this episode because these batteries are usable by just about anybody.
There are other possible liquids for redox flow batteries. Like Sodium and Sulfur. Obviously has its disadvantages, too, but has a higher energy density.
And zinc-bromine flow batteries are commercially available too.
Excellent👍
Would love to see the residential version take off.
Cheers
Have you looked into hybrid system with lithium battery and H2.
For the short term storage is the lithium battery with high C rates. The H2 dose make the long term storage.
The plus side of this is quick charge times and long term storage. And the cost dose not increase much when you ad more H2 storge to it.
The down side is the low efficiency off the H2 over all with about 38%.
Just read an article on an Australian designed domestic hydrogen storage battery that will be on the market this year. It is the LAVO 40kWh battery.
Really interesting. Haven't heard about this before. And I live within walking distance from the university where this research is done.
Man, if I lived within walking distance of a university, they wouldn't be able to get rid of me
Interesting teck,don't know if you had seen my comments on old videos,on this transmission/storage issue for renewables/green alternatives that I posted.its a simple technology ,called a gravity battery, where by solar and wind electricity lifts a gigantic 1-100 ton weight up during the day,and when that electricity is needed at night,the weight is dropped releasing the electricity when it is needed.ironically it was shell oil,that patented the teck,and the scaled down version,that looks like a grandfather clock,aimed at third world lighting,where the poor rely on kerasine for lighting.thankyou for another great in depth show,cheers liam,london
Hi Liam. Not sure if I saw your comment specifically, but I have seen some gravity storage ideas and I will certainly cover the tech in the New Year. Cheers
Redox battery. Never heard that name, but I was looking for confirmation of the concept ever since I learned about redox reactions, fuel cells, the inefficiency of hydrogen, and the energy density of pre-existing organic compounds.
This is one of my favorite channels on TH-cam. Behind CoolHardLogic tho. Nobody beats him... yet.
Thanks for the App Just downloaded it. great.
Since some viewers are new to redox batteries, I think you should have emphasized their main advantage over lithium ion batteries: It's not their initial cost, but that increasing the length of time for a given power output for lithium ion batteries requires more lithium ion batteries, but increasing the length of time for a redux battery only requires larger tanks and larger tanks are much less expensive than more lithium-ion batteries.
I love you, Dave. Thanks for teaching us.
Thank you for the excellent content
Thanks.
I try my best to keep up with this, being a simple guy.
Could you please make a video comparing Redox Flow to Liquid Air batteries? They both seem to fit into medium scale energy storage category...
In Germany the "German Energy Storage Association" has a great overview (unfortunately all in german) of the different types of technology www.bves.de/technologien-final/ Just scroll down and have a look at all the factsheets...
While I agree a video should be done on liquid air batteries, comparing them to redox flow batteries is a bit meaningless. They are solving different problems. Organic redox flow batteries are primarily solving the problem of cost and toxicity of rare earth metals. Liquid air primarily solves the problem of energy density by cheating some of the density through the reuse of the ambient environment. Of course that is also why making them work is so difficult air is full of contaminants especially on the highway or city streets which clog membranes and water which can react violently with lithium.
More specifically Potassium-ion air batteries are at least attempting to solve a similar problem as redox flow batteries by removing lithium. However those have seen almost no breakthroughs that make them viable period much less economically. However their theoretical promises are interesting which is that they should be able to achieve much higher cyclablity than lithium. However their energy density is going to suffer compared to lithium air batteries.
So the overarching topic of "liquid air" has some real players ones that actually strike balance between uses for grid scale or transportation is nearly void and there's a good reason for this. the ability to use air (mainly oxygen) is related to the use of rare earth metals with high volatility. Meanwhile fuel cells (which a redox flow battery is) are designed to react based on the presence of cations. Not saying there couldn't be breakthroughs in those technologies however just that its a significant uphill battle with competing factors needing to be ironed out.
@@Furiends I think the original poster was talking about something quite different.
"liquid air" (the air is liquid) rather than "liquid-air" (the air reacts with a liquid chemical).
It's an energy storage where air is cryogenic (liquefied) and the energy is stored in the temperature differential between ambient and cryogenic.

Yep - the same 10kWh Redflow battery
9,10-Anthraquinone-2,7-disulphonic acid (AQDS) a quinone similar to one found naturally in rhubarb has been used as a charge carrier in metal-free flow batteries. - according to Wikipedia.
yor just have a think app is just what i was searching for! thank you so much!
The problem is energy density a standard 40ft iso shipping container can store 84kw of energy, compared to teslas offering of around 150-200 kw in the same density with power grid equivalent inverter plus transformers , also crucially the outflow of energy is lower there is also the issue of temperature for the liquid storage so it doesn’t freeze this also adds to the install costs if stored outside, China has the first working grid tied load shift but needed a warehouse size building to shift 200mw 8 hours worth , so it is yet to be seen if this or other types of batteries such as variant of iron oxide with its lower cost , with its down sides of buffer for low end not being an issue on industrial scale
But for stationary use? That densitiy ratio to the teslas is still good if they last really long, are safe, reliable, simple to use, cheap and so on. And all the heavy stuff is fluid, so you could just order a tank truck filled with electrolyte, fill up the containers and there you go. For households you could also pair up a large redux flow battery with a small lithium buffer battery for short term high energy applications.
Really interesting, Thank you :-)
This is what I love about the transition away from fossil fuels. The investment in research into renewable energy is excelerating the research of viable alternatives for production and storage of energy. This will lead to better and better technologies .
Excellent info, Dave
This is seriously revolutionary!!!
Great video, very thourough as usual.
Li-ion for grid storage is crazy, no? Expensive and light and dense are nor required.

Double bubble, toil and trouble - well, I hope not too much! Good luck
Yeah, I've been hoping for a home flow battery option for a while. When the limiting factor on capacity switches from money to physical space, that is becomes very enticing for anyone with room for a spare shed, or extra room in the garage.
@@ryanbrown982
absoloutly! if i could actually get it done (i need more smrtz) and could disable the cost of the storage part, ... it seems to me a no brainer, the panels are getting ridiculously cheap and the switching components are as well.
i might have drank too much already, it says it's got electrolytes, .....
the problem would be, where to shop all the chemicals and do it right the first time, then there is the issue with power density, if I can get all that straight I will have to balance the power source, since my area is Wind rich all year and have a lot of sun during the summer.

Excellent clearly described tech.
Yay! You've gotten around to flow batteries. Have you looked into the paper "Minimal architecture zinc-bromine battery for low cost electrochemical energy storage"?. Their design uses carbon foams as the electrodes, and aren't actually flow batteries, as the electrolyte naturally separates into layers around each electrode due to gravity. I'm actually planning on building some to test as storage for an off-grid installation.
Also, Robert Murray Smith here on TH-cam put together quite a cool set of videos on it. It looks like it'll be the DIY battery of choice.
Hi Jodie. Looks interesting. I'll have a read. Cheers.
Thanks, good video!
They look like a step forward which is great . You may want to look at the Australia Hydro-storage project named Snowy 2 which is due around 2025 some highlights are :
What we need is some clear leadership in this matter, All lithium should be reserved for mobile applications, phones, laptops, cars etc.
And storage devices like flow batteries be used for all stationary applications where weight and size aren't as critical.
oh, you want a dictator to decide who gets to use what material? No thanks. That is leadership like xi, hitler, stalin. No Way!
@@dave8599 Where you thrown repeatedly against the wall as an infant? What I'm saying, is if we are running low on it we should prioritize how we use it.
Hydroelectric storage inside caves is an interesting option for none chemical and long term storage use! Solar could become green if you get rid of the batteries for the bulk of heating/cooling usages.
Have a look at zinc bromine gel batteries. Scalable, cheap, low toxicity. Sydney University development, now commercial.
I've been a big fan of flow batteries for a long time. Good to see that they are still getting attention.
I'm not that troubled with the toxicity of Vanadium, (it is locked away inside the battery after all), but a cheaper electrolyte is a big deal.
Warm regards, Rick.

Looks like the good old DHMO-gravity battery is still more cost effective. Obviously there are safety concerns over the toxicity of DHMO, a substance known to be 100% fatal because everyone who has been exposed ends up dying. OTOH it's a cheap and plentiful chemical that can be raised to a higher energy level by electro-mechanical induction. DHMO can also be stored nearly indefinitely at the higher energy level, then used to generate electricity, often without needing the inverter that other battery technology needs. That's one key to its remarkable efficiency.
Like the home storage option...
More bright ideas every day fly into the future
This is good news and it seems the price of this new tech is about the same as Tesla's prediction of a 56% drop in price of their batteries in about 18 months and Jeff Dahn disclosing of possibly the same 20,000 cycles if the lithium battery is managed well. Scaling up to manufacturing is always the big test but this one looks good.
