- Learn about the VRB, VRFB from the inventor of the vanadium redox battery and Advisory Board Member of VanadiumCorp, Dr. Maria Skyllas-Kazacos Professor Emeritus, University of New South Wales.
VRFBs are containerized, long duration, non-flammable, compact, reusable over infinite cycles and last more than 20 years. Most batteries use two chemicals that change valence (or charge or redox state) and cross-contaminate and thus degrade over time. VRFBs utilize multiple valence states of vanadium as a single element to store and release charge. VRFBs consists of two tanks of vanadium electrolyte that flow adjacent to each other past a membrane and generate a charge by moving electrons back and forth during charging and discharging. This battery offers unlimited energy capacity simply by using larger electrolyte storage tanks. It can be left completely charged for long periods without losing power and maintenance is much simpler than other batteries. The unique advantage to separate power and energy also provides significant advantages over competing technologies. With sustainably produced VanadiumCorp Electrolyte™, the carbon footprint of the VRFB is remarkably low.
The team of industry veterans at VanadiumCorp are pioneering advancements and commercializing a new generation of VRFB systems with higher performance, efficiencies and increased function.
Mass commercialization of VRFBs has long been inhibited by the pollutive and inefficient production methods of the past. VanadiumCorp changing that by commercializing patented recover vanadium from many source including waste. The resultant vanadium that makes up most of a VRFB system can therefore be green in how it is made and green in how its used.
Further to this, Vanadiumcorp also wholly owns one of the most significant vanadium mineral resources world in Quebec Canada named Lac Dore. Very few vanadium resources are capable of meeting the demand of the high purity vanadium market that includes vanadium redox batteries. The primary supply of high purity vanadium requires vanadium rich magnetite resources that have exceptional metallurgy and low impurities. In the early 2000s. Pilot production of battery-grade vanadium from the Lac Dore project was utilized successfully by Sumitomo in VRFB systems.
What sets VanadiumCorp apart is our integrated advantage and exceptional resource base. All of our resources are wholly-owned and strategically located in Quebec Canada close to infrastructure with mineralization accessible at surface. Our mineral resources and process technology that unlocks new supply are both aimed at the creation of stable supply for clean energy storage technology of the VRFB. A battery that can be good for the planet in every way with VanadiumCorp.
The animation was brilliant and very important for this explanation.
The video interestingly did not explain why the two solutions need to be close to each other separate by membrane. the whole explanation would work even if the tow tanks were kept away without a membrane.. I suppose there is some ion exchange via membrane..that part is missed, else a good video
That's amazing!
Thx you
amazing
great video. .
The Vancouver Canucks suck...
Thank you for this video! What kind of membrane is that? From what it is made of?
Love this!!!
Ty
fuck yeah! Vanadium!
Is the essentially what they are using in the quant salt water car?
AMazing.
do they make see through batteries?
How long does it take to charge? and how is it charged, from an outside electrical source like just plugging it in or by adding or replacing with new chemicals?
Just discovering flow batteries today. So what powers the pumps? Why does the liquid need to flow? How is this different from anyother "stagnate" liquid cell battery? I've heard these compared to a fuel cell. What is the difference? Thanks.
Seriously cool, this is an actual engine for the future =O
Yes I hope so .. 8 yrs ago this video .. I just learned about flow batteries 9days ago ..
@@phillyunrau4736 10 years old video and I learned about this battery technology on 14, Nov. 2022.
So where is it now?
Pretty cool. Wonder why we haven't seen this cone out or hear much else about it?
it's energy/weight ratio is really bad (about half that of a lead-acid battery)
Well electric cars were popular back in year 1880~ ish.. then combustion engines came which we're about 3 times cheaper, and polluted 500 times more. But 3 times cheaper!
@@satibel To be used for home storage so weight not important. 20 year life, lead acid 2 yrs
@@malcolmstabler2597 still, it's great tech, but people would rather have a sleek powerwall than 2 tanks of vanadium.
Though if someone manages to make to make a transparent one it'd be really cool, seriously, add some leds on that, and see one side going from black to bright purple and the other from blue to green add some ukulele music and an inspirational speech, and it'll sell.
@@vanadiumcorpresourceinc.8742 About how much power per Kg and euros per kwh does that equate to?
And how small can you make them? Like is 1-10kWh a thing?
So each side has a net charge? Wow!
What chemicals the solutions are made from? I want to make a small model heheh
Vanadium
Has anyone tried exposing ionized vanadium to strong ultraviolet wavelengths?
how to do the animation shown in this video
Hello I can t not listen for vdo clip. I want to subtitle for vdo clip English Vocabulaly. Thank you.
what is performance?
It helps if you don't pee in the vanadium tanks
seller link,website corporate?
Vsauce cx
So whats the drawbacks to this?
***** I believe size is the primary drawback currently.
Also, this is probably fake
***** How can it be fake when it's just a theoretical computer model?
I meant to say unfeasible according to some clever people, it's too good to be true
***** It's feasible. It's just only been tested in labs and the payoffs probably don't warrant the price or size.
But this is technically how all batteries work. Two chemicals separated by a membrane. Electrons trying to get from one side to the other.
A similar thing happens with metals too. ;)
Pretty cool once you think about how nature is always trying to balance things out.
Talk about over my head! If the solution lose' an electron, why does it go from a V4 to a V5? equally, if the neg. solution gains an electron why is it a V3 then a V2? Not to mention I don't full understand how it gains a charge, they may have explained it but again over my head?
Electrons are negatively charged, so when you give something an electron it loses charge.
You charge it by plugin it into an electrical current, that drives electrons into the solution, which stores the energy.
When you use it, the solution returns to its original uncharged state and gives back the current you've inputed.
Kavryel So you have the solution right, then an external charge to it will realise an electron, which gives of enegery that is then tranfered to the other side of the box that will hold and be used?
realise is not the correct word in this sentence, but if you mean "make" then yes you're right and you understand it as much as i do.
It's magic.
But whats the point
First time I've looked at this. I don't get it. It seems ridiculously simple. Negative ions in one tank. Positive in the other. Connect em through an electric motor and you get current. Power the electric motor from an outside source and you charge the batteries. This is what I'm seeing. What I dont understand at all, is the membrane.
The membrane serves two purposes. It is most likely a catalyst for the V5 to give up the electron. it also must provide the path of lease resistance for the electron to travel and directs the electron through the battery for charging or discharging.
rockboy2003 Since you seem to know something about this technology, can you tell do you need to buy an specfic solution for this or can you just get water to power it up. And how much it will cust.
I seriously doubt the membrane is something you can just buy. most likely its something that was developed by whoever created the battery. The video is more of a proof of concept. I know that this technology is used in the worlds first Salt water car. Im sure if you google Saltwater Car you'll be able to read up on it. very amazing stuff. too bad the oil and automotive corp giants will pay billions to keep that stuff out of the US
rockboy2003 Oil and gas companies don't have to do a thing to keep this out of the US; the technology is not easily adaptable to civilian use. I suspect that's part of the reason that the "World's First Salt Water Car," the QUANT e-Sportlimousine by nanoFLOWCELL AG, is projected to sell for $1.25 million. The oil and gas companies don't have to worry... yet.
Crown Clown Several types of flow batteries exist, representing several approaches to overcome the problems of the technology and getting as much performance as possible.
