Time will tell, of course. It might make sense since they just changed their name, AND….there are so many “new” battery and battery mineral companies over the last year, it just might help get their message out there to the real people concerned about energy storage. I’d spend more on getting those in control of the money and procurement my information than “the people”at this point.

Just wonder what that cost ’em. I hope that 5W didn’t approach them first. That would change my mind in a hurry. Nothing against 5W at this point, but I think way too much is placed on marketing guru’s these days based on social media alone.

I believe that for the most part, you discuss your needs with a company and they build to your needs. I have not found a smaller “home version” readily available yet, but maybe this link will help you get a basic feeling for price:

from :https://spectrum.ieee.org/green-tech/fuel-cells/its-big-and-longlived-and-it-wont-catch-fire-the-vanadium-redoxflow-battery

We’ve also brought down the batteries’ cost: A few years ago, the cost of a 4-⁠hour VRFB system was about $800 per kilowatt-hour. These days, it’s about half that,

deanbob, Yeah….I haven’t looked for a while myself. I would LOVE to be able to get a good battery and hook up solar / wind to get me the juice to use later. I have some ‘farm’ property we inherited years ago, but have not built anything on it yet. Seems like everyone wants to charge me a fee for goods and services! Imagine that. And here I am trying to make good on debts. Oh well.

I bet Cowboy can’t wait either, but with him working in this area, he may be coming across some interesting finds real soon. I think that the Li batteries will still sell for a while until this “new fangled thing” called VRFB is common speak.

Cost of VRB battery…… Short extract from https://www.renewableenergyworld.com/articles/2014/07/lithium-or-vanadium-in-energy-storage-its-no-contest.html
” HomeFeatured News: Lithium or Vanadium: In Energy Storage, It’s No Contest

”Energy storage is poised to transform the electricity industry. In the U.S. alone, energy storage will grow 6x, from 120 megawatts to over 720 megawatts by 2020. Globally, it will bring power for the first time to over a billion people by letting them tap into micro-grids.

Lithium and vanadium have both been offered up as a basis for the storage economy. But which technology will win? Here are some facts about each – draw your own conclusions.

Cell Design

Lithium

Lithium batteries store their energy in cells. Some are flat. Some are cylindrical, but you’re familiar with what they are: relatively small, self-contained devices that get hot. There are probably two in your phone and six in your notebook. But in a grid scale storage system, you need hundreds of thousands of them. It would be sort of like building an industrial-scale cold storage facility with a bunch of portable refrigerators. You can do it; it just won’t work well.

Vanadium

Vanadium flow batteries store their energy in tanks. The electrolyte — the fluid that transfers charges inside a battery — flows from one tank through the system back to the same tank. The tanks can be fish tank size or bigger than an above ground pool. As a result — and you will see this over and over again — it’s much easier to adapt flow batteries to industrial-scale applications without adding a lot of cost. You just make the tank bigger.

Cost

Lithium

Bloomberg New Energy Finance says the average cost of a lithium-ion based storage system is $1,750 a kilowatt hour. The cost includes the cells, electronics, installation and balance of systems expenses. By 2020, Baird Research projects that Tesla Motors’ planned gigafactory will be able to produce energy storage systems for $400 a kilowatt hour — all in — and sell them for $500 a kilowatt hour.

Vanadium

Some vanadium batteries already provide complete energy storage systems for $500 per kilowatt hour, a figure that will fall below $300 per kilowatt hour in less than a year. That is a full five years BEFORE the gigafactory hits its stride. By 2020, those energy storage systems will be produced for $150 a kwh.

Then there is scaling. If you want to double the size of a lithium system, you double the price: a ten kilowatt system would cost $17,500. With vanadium, you just increase the size of the tank, so the price per kilowatt hour goes down. Suddenly, the prices are going in different directions. Bigger is better.

Lifetime

Lithium

Grid batteries have to last for decades. The average age of a substation transformer in the U.S. is 42 years. Lithium ion batteries have a finite life. Performance degrades over time and is impacted by heat, operating conditions and how deep, and how often, they have been discharged. Battery University notes that the capacity of lithium ion cells can drop to a 50 percent level after 1,200 to 1,500 discharges.

Vanadium

Vanadium-based flow energy storage systems can operate forever. The active ingredient is a low-cost, rechargeable electrolyte, which never wears out due to the type of chemical reaction involved. The electronics and software to manage the system can be easily upgraded like any computer. The last major component — the plastic tanks for holding the electrolyte — lasts for decades.

Applicable Markets

Lithium

So with lithium you’ve got a small, expensive battery with a finite lifetime. To build a storage system for running demand response programs or a backup system that can provide four to six hours of power, you need thousands of cells. It’s like building a warehouse-scale facility with suitcases.

But it gets worse. Lithium batteries also are subject to “thermal runaway” reactions, i.e. they can blow up.

Vanadium

Vanadium-based systems are made for industrial-size applications from a few kilowatts to several megawatts. And there is no danger of thermal reactions”

So I still dont know the cost but it sounds a whole lot cheaper than a Tesla battery pack.

NP Tesla !!

I really think that the only reason that WE are aware of them is because we “stumbled” into their existence. Everybody hears about Tesla. Artificial Intelligence, Self driving cars, huge…HUGE solar farms and maybe….just maybe, there is a reference to battery storage. These are the stories that make up the ‘news’ about GreenTechnology. Not stories that we read in our research. (Most other people are too involved in cussing each other out on social media.)

Another thing is that there are still many different types of workable batteries, with no one type being considered as the best. We may still be in the “prove it” period for companies, before they go all in. There are still sooooo many types being tested and touted..

I feel that this may be the time for acceptance of a few types of batteries, ones suited for unique situations. Some better for cars or machines, others for small houses, and others for mega power as needed, (like for one of Alan Harris’ and alansd’s Concerts)

I still think that we are early by a couple of years before people start to
know and understand that they are available and actually work.

The one thing I don’t mention is that a VRB can be simultaneously charged and discharged. The battery life should be given as about 20 years for Li-ion and about 30 years for Vanadium. When the battery life is up replace the Li-ion and on the vanadium replace the electrolyte.

I forgot to mention that if you have an existing PV system and you are going to add a battery check with the IRS for a Tax deduction. I posted that a couple of months ago about the same time I posted about FERC deregulation. Might check with your local utility as well with the FERC dereg the utilities are thinking of themselves.

Hi Sarah…..welcome back. “I’ missed you!!
???? Peeps…… I have questions for et all……be patient with me Sarah.

about the off-girders and farmland. I find it unsettling to see acres and acres of land covered in solar. Reminds me of ‘mono culture’. If there is any major volcanic interrupt, there goes solar. With the increase of volcanic activity the world is experiencing, any major occurrences will interrupt food sources and now solar. Have not yet, Not sure I’m going to invest in solar. Nope….

If Vanadium is for storage, I understand that part and I am following it, but where does it get the power? Silly question, perhaps but I want to understand.

There are 12 or so hybrid cars in my buildings parking garage. None of them ‘plug in’? How is it there are electric/battery when none plug-in?
{off subject: New version of SBD, silent but deadly ( no noise from those cars!!)}

EV- none of the homes or high rise (high priced) condos being pre-sold here are Ev ready? I see these electric plug in stations at some major Hotels(Penticton/Kelowna) so are they for Teslas only? How is a Tesla different from a Toyota hybrid? I thought they cud both plug in but the hybrid allows for gas for long distance? How will people plug-in.
I keep seeing the picture of 10 years between all horse n buggies and 1 car and all cars and 1 horse n buggy……I recognize the disruption.

I live in Penticton, BC ( googled it, you will be amazed at it’s beauty) but it is ‘newly wed and nearly dead’…..the big news at the Friday night barbeque is ‘ we can have 4 pot plants legally or the bachelorette is on TV’, really, I tell the truth!

Lulu my lovely; How nice to be with you all again after my unpleasant banishment…..actually Im still banished from being irregular, but even if Travis doesnt want my $50 and decides to bin Sarah from these free sheets, you can’t keep a good ‘girl’ with an infinite number of usernames, 100 gmail accounts and a virtual server or two, away for long.

The shortest question always require the lengthiest answers. and mostly youre talking about ‘simple’ energy… Oi vey!. As the Russian physicist Lev Okun said, “The more basic is a physical notion, the more difficult to define it in words.” For energy, the best we can do is say it is a ‘force’ that has the potential to cause movement. But what is it and where does it come from?
Energy is the cause and by-product of any conflict. While it defies precise definition or (presently) meaningful scientific quantification, in layman speak we can think of it as a transient ‘force’ (and may it be with you). Energy is silently floating all around us and beyond (see the real Mr Tesla’s experiments).
Our world (indeed the whole cosmos) has 2 other elemental and opposing forces….gravity and friction (I’m sure someone will argue that there are many others too, but these 2 will suffice this explanation). These forces happily sit around minding there own business until some form of energy tries to push them around….each then resists and some energy is expended. Once equilibrium is restored most (but not all) of the energy is released back into the space/time continuum. Energy is useful stuff coz it can be used to power the machines which save humans a lot of time/effort = increased productivity = profit. So ideally we want to capture that energy for our on-demand use. But energy doesn’t like being captured or corralled. All man made forms of these storage devices are known as batteries (Like all vacuum cleaners were known as Hoovers….did you ever Electrolux your carpet?). Many versions have been (and will continue to be) invented, but each has its downsides.
Lithium batteries
Lithium, in conjunction with cobalt and other ‘rare’ metals, do a passable and inexpensive job of storing small amounts of energy (we call it electricity). But they can overheat due to the chemical reactions, which causes friction, which creates heat….they can even explode. Also, like nearly all other batteries, relatively little electricity can be stored (the physically smaller the battery, the less it can store) plus the whole device has a relatively short life span. One other important downside is that they can only charge, or discharge. So, typically you charge them up during the day when the sun is out and discharge them at night when you need power/light.
Vanadium batteries
These batteries are not flammable, they can both charge and discharge simultaneously (which is useful for hydro applications where the river runs 24/7 (or can be caused to run 24/7 utilising a reservoir lake) and are also infinitely (and cheaply) expandable. BUT they are huge (ish). So they’re great for mass storage to power the grid, but not much use for directly powering your watch.
Presently we have to use the horses-for-courses method of energy storage. But one day we may find a means to extract the energy that Mr Tesla claimed, surrounds us all, direct from the ether !
So Lithium is well suited to smallish solar/wind type energy harvesting, whereas Vanadium’s charge+discharge capability is better suited for 24/7 hydro generation.
Which to invest in? Short term lithium dominates the market, though the margins shrink a bit everyday. Whereas the whole world will need an ever increasing supply of clean, grid power. Building a vanadium battery is quick and doable today, but building the necessary hydro dams and infrastructure tends to take a tad longer.

Now about charging the ‘electric’ cars. There are two types of ‘electric’ cars: fully electric and hybrids (80/20 gas/EV). Typically, you don’t charge hybrids with an electric cable….they charge themselves while you’re driving along. You burn gas to go uphill and you coast downhill. The coasting and braking creates kinetic energy thanks to inertia, gravity and friction. The resulting charge is then stored in the hybrids battery. That battery is far smaller than a fully EV battery so it can only move your car short distances (maybe 2 miles)….typically its just used to start the engine and get the car up to speed; then the gas engine cuts in for the cruise. Come the next downhill, the battery soaks up some more kinetic energy…..wash rinse repeat.

Re condo’s. Its pretty easy to run a wire to your car. But I don’t believe we will need to buy our own cars in the future…..90% of the time our cars sit in the garage or gutter, which is an idiotic waste of an expensive asset. In the future you will simply press a button and (like Uber) the nearest autonomous car will pitch up on your drive to take you to the mall and back. For long journeys the car will take you as far as it can on its charge, then you’ll switch to another fully charged car till you get where you’re going….think pony express.

BTW its proposed that future SBD cars will be fitted with a noise emitter.

Hope that helps and please save me a burger at the barbie.

Hi Lulu, just a few thoughts on the questions you raised.

SUNLIGHT INTERRUPTIONS Yes something can go wrong with sunlight also. Volcanic activity could result in obscuring the atmosphere for significant periods on large areas, Krakatoa in 1887 had world-wide effects; as did astronomical encounters in quasi-historical times.

EV CHARGING AVAILABLILITY Concerning availability and distribution of EV stations and so on. They will appear overnight as needed. Do not be worried about this aspect. The installs will suddenly appear everywhere. There is already the basic infrastructure of electricity and locations….gas stations and parking lots will just add charging stations.

Compare the capital and construction needed to build a gas station, compared to a charging station. Gas stations need huge underground storage and regular delivery of thousands of gallons of fuel.

VANADIUM IONIC CHEMISTRY batteries operate on account of differently charged elements in their electrolytes, which cause migrations of electrons from one terminal to another. The advantage in vanadium VRB is that you do not need two separate elements, you need only vanadium in the electrolyte; the two elements are both vanadium, separated by a membrane; but one is in a different charge state than the other. The electrolyte has two isotopes of vanadium.

Because of this VRB batteries can charge and discharge at the same time,
and the process can be repeated tens of thousands of times with no obsevable degradation of the electrolyte.

COSTS Zinc-air and vanadium….These grid storage chemistries are modular. Technically they are fesible on smaller installs.

They are approaching competitive costs in the big grid applications, and in my opinion their ability to compete will improve.

But for smaller scale distribution, they will not be cost competitive until the large-scale market is more developed, because it is only with scale
that the costs will be dramatically affected.

Vanadium has a short-term hiccup because supplies of it are tight.
There is not a lot of it produced. This gives me an idea…oh never mind.
If you like the story, just buy Largo and CLQ and keep your fingers crossed.

Zinc-air has an advantage in that zinc and air are plentiful compared to vanadium, cobalt, or even nickel.

In addition to the well explained comments above, the basic fact is that NOT ONE source of providing electricity to charge batteries is a given. You can’t be sure that there will even be electricity at your house when you flip the switch.

Anything can go wrong and we haven’t even talked about terrorism. Mother Nature likes to keep us in check every once in a while, but we here in the US have been very lucky so far. I don’t think that Mother Nature is online, but with everything else being done on computer, Cyber Crime/Terrorism could be our worse nightmare.

That is why I firmly believe that we cannot just use one method of creating electricity, but many to suit different needs, and as backup to even store that energy. We’re looking at batteries to backup our grid, but what about backing up the source of power to that battery?

Maybe invest in a company that does many things and not just solar.

I’ve been lead to believe that changing the battery composition changes the battery characteristics, self discharge, capacity, charge rate.. There was a company several years ago that taunted a Li-ion battery that you could park for a year and still start the vehicle due to a change in Anode and Cathode composition. That company (OGES) has since disappeared and I haven’t seen any info since that gives info on changing what metal in the battery changes what characteristic.

$FYI – Long time coming – 6/15/2018

https://www.vanadiumprice.com/long-time-coming/

This article was in this morns “Long time coming” from VanadiumPrice.com : Newsletter.
IMO this article is not that well written and confusing. What prompted me to post was th is “Already awarded is a contract for Rongke Power, which has a well-known subsidiary in the US, UniEnergy Technologies (UET), to install a 200MW/800MWh flow battery system in Dalian Province, with the company itself having emerged from the Dalian Institute of Chemical Physics originally.”. First it appears that UET is working with Pu Neng on the Dalian Project. UET is a small private company in the state of Washington that has been work9ing with VRBs for many years. They have also collaborative work with PNNL so I would say the UET is on the leading edge of VRB technology.
