When it comes to grid-scale energy storage, redox flow batteries (RFB) are one of the big competitors for lithium-ion batteries. In preliminary tests, vanadium redox flow batteries can be manufactured with longer lasting lives, be made more scalable, and are easier to recycle than other battery technologies. Yet, after investing millions of US tax dollars into a cutting edge flow battery formula, the American government basically gave it away to China, who is currently the lead producer of RFB. So, how did this invention flow out of the US? And why should we even care about redox flow batteries?

I believe the point is mostly an economic one. Specifically, the current licensing of the technology is allowing China to develop this technology and make money off of research and development that the US government made. Think of it this way: if you put money into the stock market and someone else then got your stock and any profits from that stock you probably wouldn't be happy about it. Additionally, I do not think we should trust China to do the right thing when it comes to environmental or human protection. I believe our standards as higher than China and corporations are held more responsible to their actions here so it is also a safety factor.

Having said that, America does have some laws to protect its domestic environment but it will be oblivious to the environment outside its borders. For instance, when China ended imports of millions of tons annually of contaminated "recyclables"/waste after years of warning it would do so, the US demanded China continue to take in its waste. Prior to this, China said it would reduce output of rare earths to reduce its environmental impact, the US which uses the very same reasoning to not produce rare earths coddled the EU and Japan to force China to meet their demands.
@Jon_an_engineer Рік тому
@@downtomars6268 I don't agree that the 737 Max thing had anything to do with China. That was more the typical US problem of businesses getting too close to regulators. If I recall correctly the FAA was basically just taking the word of Boeing that their planes were safe or that people didn't know all the facts. You see similar patterns when it comes to cigarettes, global warming or any other impact to a business's bottom line basically going like this: report comes out of risk to the public, businesses pushes back by exaggerating the uncertainty or doubt about the findings while raising fears of how it would effect the economy to do any regulation about the issue, issue becomes a political one and gets endlessly stuck in legislation. As you might guess I don't think the US is perfect. I agree that the US is generally blind about environmental concerns outside of the US; though I would also argue that things that get screwed up, like the plastic thing, is due to a level of misinformation provided to the people by the corporations that benefit from that misinformation.

A group of engineers with NRECA and I visited a redox flow battery manufacturer a decade or so ago, somewhere in the NE US mainland. We spent a half a day there, learning about the issues they were having in design and manufacturing. They were building flow batteries into modified shipping containers for a project in a remote Alaskan village. The thing I remember most about the batteries was the complexity of the monitoring and control of the system. There were wires and circuit boards everywhere. I thought about how many things could go wrong. Maybe it was all just monitoring and not really necessary for operation, but I don't think the batteries ever went in service due to breakdowns or failures. If anyone is familiar with this project, I'd be interested to hear what ever happened here.

It is international reliance, international trade, that makes peace the preferred state. It is also the state that leads to the largest supply of goods to go around, and thus the highest quality of life. Self-sufficiency is for the bad actors, who want to abuse other nations without consequences. A strategy that usually leads to impoverishment, like in North Korea. We could grow bananas, but they would cost $4 per banana. And only rich snobs would buy them. We have already gone too far with this. Corn syrup cost far more to produce than cane sugar, but we slap a huge tariff on cane sugar, so we can all be forced to pay more for corn syrup. And there are plenty of other examples. Our big problem is that our companies don't want to produce in high volume and compete internationally in high volume products. Too many business majors who want to find some angle to gouge. That and unions kill companies. NIMBYs, of course, are also a problem. You never hear about unions striking in China. The reason our mines produce about 1% as much as China, is unions. If there is any obvious value to the ore, the unions destroy the company. The only ore we lead the World in is Fuller's Earth, AKA kitty litter. I Am not saying we should not have some economic robustness, but I think that is better achieved by the Fed storing materials, food and drugs rather than merely oil. We used to store other things. Not so much anymore.

Had been keeping an eye on the Redflow company in Aus which produced some zinc-bromine units that you could install in residential homes, the only issue being the smell/gas toxicity apparently, needed to be installed in a very well ventilated space in case of off-gassing due to the bromine used in their electrolytes. Unfortunately I don't think they are pursuing their residential home battery lines (ZCell) anymore and are moving onto just their industrial versions of the ZBM3, which is unfortunate, as I really liked the idea of the safety of using a battery that isn't potentially going to burn down my home.

I was thinking how this battery is more of a plumbing system than an electrical system. Curious then if you could put these holding tanks of the electrolyte solutions at some distance from the electrical components. Also considered that installation could be accomplished in tight quarters or otherwise underutilized oddly shaped locations by installing custom shaped tanks, perhaps even bladders confined by simple wood frame boxes. Also, the fact that it is a liquid filled tank means that you would presumably install the tank empty making it very easy to handle and put in difficult locations (like attic spaces) and then fill the tank with a hose and transfer pump from a convenient distance.

Rabbit Hole (1) Iron-Air: Not sure if it's worth the research, but twenty years ago, an American company developed the iron-air battery and the US Military labeled it disruptive technology and outlawed it. In other words, our military has been stopping progress and preventing technological development. Rabbit Hole (2) Thorium Salt: Current reactor design was selected (and enforced) for it's ability to make material for bombs. We had a running Thorium Salt reactor for a year. Somewhere around 1967. This design can burn most of the actinide sequence. They run at ambient pressure, 750 degrees, so much safer on that front. The waste is over three hundred times faster to become harmless. If they do manage to overheat, the molten salt just dumps into a cooling chamber, so much safer. And lastly, they can burn the waste from the current idiotic designs.

If I can build you a reactor with four thousand percent fewer parts, it will break less, be easier to manufacture, and will produce very cheap power, especially if cost is calculated over the entire supply chain. It is also worth noting that Thorium is sitting around in giant piles all over the Earth, because it's produced as a side effect of mining rare earth minerals. The reason we hear so much push back on Thorium is probably the same reason we turned off the US power plant: They don't produce weapons grade plutonium.

Rather, Rongke Power invested $72M into US collaboration to fund over 300 man-years of work by US engineers and scientists. Rongke also willingly shared access to crucial advanced components and production technologies to together deliver the breakthrough modular vanadium product. 3: The US tech electrolyte is no longer being produced in China, despite Rongke investing two decades and over $100M to refine vanadium electrolyte production and then apply it to the US tech. They are still the only ones who know how to make it, and it will take many years to develop the process in the US.

Hi Matt, long time viewer, but my first comment. I am not sure if you read these comments. Thought you might be interested in Redflow Batteries. It is an Australian company based in my hometown. It is another flow battery, but the liquid is less problematic than using acids. It is a zinc-bromine flow battery. No idea what the LCOS is, but imagine you would be able to figure it out :) I would love to see a story on this if you think it is worthwhile.
@ericmcquisten Рік тому
An Australian company produces a type of (electrolyte) Flow Battery that uses Bromine, which is completely inert (safe) and can last nearly 100 years. What's more, its charge doesn't discharge over time, and its efficiency degradation is incredibly slow... meaning even if you haven't used the battery in years, it will still have the majority of its charge, so it's ideal for stationary energy storage solutions. The (RFB) flow battery discussed in the video, seems to be a more dense version, and thus requires a smaller footprint

Hi Matt, thanks for a great video! I'm wondering whether this tech might be a way to fuel up one's EV (how large would be the volume of the electrolytes required), how it would compare with charging or perhaps fueling up H2 for a fuel cell based EV. I also remember one of your other videos about storing H2 on a metallic surface, which I think is also a remarkable idea. Thank you!
@vremster Рік тому
Yes, these would be great as a buffer at EV charging stations. When a station is full of EVs, all fast-charging at once, the vanadium batteries could take some of the strain off the grid. Then when there are few cars, they could recharge.

VRFBs are definitely a good solution for charging EVs, also good to store excess energy to use for hydrogen production when renewable generation isn't available
@dparalen1808 Рік тому
...just revisited the topic with the RedFlow design, the energy density of their electrolyte is around 0.1kwh/kg. When compared to diesel, with some 0.3kwh/kg (accounting for 30% engine efficiency), one would have to tank 3x the amount of electrolyte to get the diesel mileage, very roughly speaking. So we probably won't be pouring electrolyte into our car tanks just now but the gap isn't actually that bad, what do you think? Thanks!
@cplai Рік тому
I heard that one possible use of flow battery would be in EVs. Instead of recharging the battery at a charge station, the depleted electrolytes on the cars are swapped with the charged electrolytes. Then the depleted electrolytes are charged at the charge station getting ready for the next swap.

Still, I think RFBs are the best solution for longer term storage and should be widely deployed to supply power at night when there's no sunshine.

Just to recap there is a common positive and common negative electrolyte so as a flow battery u have to limit the power lost through the conductivity in the electrolyte between cells. The higher the voltage the more loss as the conductivity stays the same from charged to discharged. I suggested a method to do this based on the film projector Maltese cross mechanism though it moves is can be disconnected electrically speaking. The big advantage of the system is a few low voltage cells at high amps can be in series with the high voltage stack .u can tap multi voltage points for all sorts of purpose .

Flow batteries (independent of chemistry) have an important difference from wet and dry cell batteries. They can be turned OFF, meaning there is no voltage difference between the Plus and Minus terminals, even when "fully charged". Just drain the reaction area of electrolyte(s) and they are completely OFF. You can short the terminals. Also, if the charged electrolytes do not degrade on their own when confined to the storage tanks, there is no self-discharge.

As we ramp Lithium batteries, especially iron phosphate, it becomes harder, and harder for competing technologies - unless they can prove that they have an outstanding advantage. Anything "mechanical" can suffer degradation over 10-20-30 years - and it's not always easy to predict, until they have that long in the field...corrosive, toxic or high temperature materials likewise. Batteries can be switched vary rapidly (milliseconds), so can provide more services to the grid. Having said that, we need to trial different systems, because unless we do, we might miss an even better solution !

Really good episode this time though you did make a mistake in the context of California summer generation issues. That is a situation that typically only occurs once a year in CA, usually for a few days and it is only applicable to the 4pm-9pm time period. In otherwords, these Redox batteries aren't useful for that particular problem space. During the most recent heat wave, California had plenty of margin for most of the day, particularly across noon, all the way up to 4pm. So much so that the ISO recommended that people pre-cool their homes across most of the day in order to be able to then reduce their power consumption from 4pm to 9pm. Short-term storage is and CA is pushing hard for more energy storage just in general (solar is over-producing so we need energy storage in order to continue expanding solar and wind). At the moment, California has grid-scale batteries approaching 3GW of output (about 10GWh of storage or so, off the top of my head). This is ideal for Lithium ternary and LFP battery installations. Not so much for redox. Where Redox style battery systems will really help out is with overnight generation... where the grid needs steady but fairly low-to-modest power generation for many more hours... around 10 hours instead of higher output for 4 hours.

Ask Ukraine what Europe's cooperation and energy dependence with Russia has done for them.

It does not really matter who makes these batteries and improves green tech so long as it is widely available. I assume that China's bigger market, lower costs and economies of scale mean it will likely dominate this particular technology at the international level. That is fine with me if that means that these batteries are more affordable to people all over the world. The same goes with any other green tech. As an aside, the US has been putting up obstacles to dealing with climate change for decades. By contrast, China has been trying to develop this tech for a long time.
