Gelion designing the one battery so that it uses the vast majority of the existing lead-acid battery manufacturing steps was a stroke of genius. Far, far too many potentially revolutionary battery technologies never make it out of the lab because they fail to make the jump to mass production, but I bet this one doesn't meet that same fate. The high functional temperature range and nonflammability are great, too, it means I could theoretically put one in my uninsulated garage and not care that the garage becomes an oven in the summer and a freezer in the winter. The thing would likely still work safely regardless.

I just think that comparing lithium and zinc bromide was a poor choice, seeing as it looks like compared to the 2nd most common battery ever, lead acid, zinc bromide wins in a landslide, the big one being that you can’t use half of your lead acid battery without damaging them, with there DOD being really bad, he also mentioned they’re more energy dense then lead acid. So there smaller and can discharge further, while also being affordable… I know that would have made this one sided if he was comparing zinc bromide to lead acid, but for me, when you can make better car batteries, better off grid power storage for farms and boats, what’s not to like?

I think this one's decided there Matt... As a half-Aussie I'm STOKED to see this coming out of Oz - it makes me so happy. God I hope they start pumping these out as fast as humanly possible, even if it's an evolving product. Use them for fixed location storage exclusively, standardise the installation and access mechanisms, get it into place in a practical sense and make sure the end client is aware it's a version 1.0 solution and will evolve/improve. Here in the UK we're running into grid problems (not just generation) and I have read that we may not be able to carry and deliver the power requirements for wider scale adoption of EVs mandated by soon-to-change regulations. We really really need distributed grid storage and rather badly... Australia has a strange mixture of savagely overpriced power (a side-effect of pseudo-competition overlaid on the old distribution structure) and power is monumentally more expensive than it should be; despite that they've endured brownouts and blackouts where there is no way that should be justified (this isn't a bushfire or flood thing, it's a government and mismanagement thing apparently). Imagine these popping up under houses and tied to domestic solar arrays, etc. - the amount of sunshine they get is hard to fathom. As for going outside - I know how those noodles in the microwave actually feel. The sun is harsh and relentless much of the time, if these really are much cheaper then the main problem will be getting your mitts on these batteries and infrastructure (God help you trying to find a licensed installer then). Not sure how many lead-acid plants we have in the UK but licensing that tech would probably make sense, even if it ends up being a stepping stone before fusion reactors take over the world (as the media claimed this morning) we really do need that interim step. Even more so if international tensions and war is on the horizon; this makes a grid vastly more difficult to knock out indeed. National grid resilience is just not sold hard enough by either the industry or government (against attack or disaster) and I really think we need to step that message up sharply. These types of devices are the meat and potatoes of making that happen, absolutely LOVE it.

The Bromide and Sodium based batteries will probably be ideal for these uses, and both should bring storage costs down. I'm expecting that Sodium will also replace the LiFE batteries that are currently popular for Tradie Truck dual battery, off-grid living and camping power solutions. Davo's spot on about finding licensed installers - there's a lot of people going DIY for the automotive and camper installs. Every country needs grid resilience, the lack of it is why it's very easy to upsell UPS units for PC's and security systems, and that's something the Virtual Power Station model can help fix, especially while many of the deregulated corporations over charging for power are busy ignoring the need for grid maintenance until things fail.

I have a large lithium-ion DIY powerwall in it's 5th year of operation. Over the last 5 years, LifePo4 has taken DIY powerwalls by storm. A key difference between them is the voltage range. Lithium-ion has a relatively large (3.0v -> 4.2v) operating range so you can set max charge/discharge by voltage to manage DOD. LifePo4 has a very flat discharge curve which means it's preferred to do coulomb tracking instead of the simpler voltage approach to manage DOD. MY POINT: One thing you don't mention in these battery technology discussions is the voltage range - e.g. flat like LifePo4 or wider like Lithium-ion. And are they compatible with nominal 12v, 24v 48v systems. For example, lithium-ion does not work for 12v systems as neither 3s or 4s matches the voltage range of standard equipment properly - but does fine for 24v and 48v equipment. LifePo4 does all 3. I agree these are smaller points :) but I'd suggest that these youtubes are nerdy and the voltage range, 12/24/48v compatibility, BMSs available?, and cycles are of great interest to DIY folks like myself and would add interest in you're presentations.

Great video Matt. Its good to see this with the companies like Redflow having their products actually on the market, not just in labs/testing. These seem to make so much more sense for many non mobile storage solutions. They also had some good claims about losses when the battery was idle that seemed to be another real advantage over the lithium storage solutions. It seems like lithium is more riding a wave of popularity and more people need to be made aware of other solutions that may be more suitable for specific applications.

From the European point-of-view we seriously need to focus on energy storage that handles the "last mile" meaning distributing the energy storage as close to the homes as possible. Having a cheap, safe battery to put into basements and car parks is essential for this application. We cannot build the whole infra to handle EV cars and going "all electric", so we need to "trickle load" a very distributed energy storage that is as close to the homes and cars as possible. We also need a lot of storage as many countries have waaay over built wind energy.

Great update on these batteries. I definitely would consider them as a possible home backup storage system (if they become available for the USA residential market). I will have to check into this possibility.

Australia, with its abundant sunshine, is ideal for such a battery placed in the back of every garage in every single family home, not to mention larger stores/shopping centers. My friends in the country talk of EVs selling out whenever available and proliferation of rooftop solar. I think it's only a matter of time (and, perhaps, govt policy).

Hang on a minute. The Redflow battery is not a typical flow battery in which the electrons are exchanged between atoms of the same metal in different oxidative states. It is a plating battery in which Zn is plated on to a substrate during charge and goes into solution during discharge. As for full discharge, they must be fully discharged periodically to avoid spicule build up. For this purpose it is useful to have two of these 10kWh batteries. Periodically one is fully discharged into the other.

Hey Matt! As a Filipino consumer who is acquainted with carbon-zinc, alkaline, and lithium-ion batteries, I was pleasantly surprised to hear that a zinc-bromide type battery has been existing for 137 years. However, it was not even mentioned in our high school science classes here in the Philippines. Anyway, thank you so much for the video presentation. I really hope such zinc-bromide battery technology will be gradually re-introduced in the global market.🇵🇭😉☺️🔋🔌

The round trip efficiency for the LiFePO4 (also known as LFP) lithium chemistry is around 95%, actually. This is where essentially all lithium-based vehicle and fixed storage systems are headed. You may have been quoting efficiencies that include the charge controller in the loop which would not have been an apples to apples comparison, or other lithium chemistries which don't represent where the technology is heading.

An excellent and well-explained video Matt! You find ways to explain complex technology to those of us without an EE degree. Thank you. Sounds promising for use downstream of renewables in both large scale and home/office backup.

Although I love the idea of making better use of Iron, it does sound as if Gelion and Redflow have their grid compatible products ready for retail. Especially here in Australia with so many households pumping their excess photovoltaic power to the grid each day, we're in need of grid sized battery capacity; and a tech that would have better than a ten year life with daily discharge sounds quite plausible.

Given that Li based batteries are still the preferred choice for EVs, any technology that replaces the need for Li batteries in stationary storage is a good idea. If I understood correctly it appears these companies are already in production, so this is a real, not an uncertain future technology.

Would be very interesting to hear how these ZnBr batts compare at single house scale e.g 10-20 kWh. There are still people installing Pb-Acid batts due to the immediate cost and (perceived?) fire risks of LiFePo, even though after 5 years they start regretting it. If the material costs really beat LiFePo, I can see a big market in that sector!

Hey Matt, I've been watching your videos for some time now and due to the many, many different energy technologies being explored, each trying to improve or solve a particular part of our complex energy needs, it's becoming very difficult to compare/contrast them. Have you considered moderating leaderboards? One for say Utility Scale storage at cost/kWh, another for energy production at LCOE? Maybe with projected environment impact costs thrown in? A leaderboard for small-scale storage like vehicles would be good too. And you regularly make content anyway when new companies come on the scene and existing companies make improvements...a perfect time to update the appropriate leaderboard. Finally, it might be a good way to give citizens a simple, understandable, and *impartial* view of the data when government leaders are making decisions and/or picking winners/losers.

Honestly, letting lithium have its niche as the small battery while letting something more affordable take up the big battery position with fewer downsides sounds like the best of both worlds. Less investment of lithium in these massive storage plants means more lithium to supply portable batteries, while the arguably more recycle-able Zinc/Bromide can take up the bulk of space and cut down on costs involving fire prevention systems, with those also being put to better use elsewhere. It sounds like there should be a catch somewhere.

Thanks Matt. Storage seems to be the one factor that most national grids lack, and it becomes very obvious during times of grid instability or power shortages for whatever reason. I think about batteries and inverters everyday, more so during power outages (every day for several hours a day currently).

I have always been pro-Flow batteries for grid-scale. With Lithium and other precious metals being used for car batteries it does not make sense for mega packs to be wasted on grid-scale energy anymore. As long as these can be stacked up in shipping containers, then they can be very useful for being placed right in the middle of cities instead of wasting land out in the middle of nowhere.

So the cost of these innovative battery storages is $52 kW/h. Nuclear is ~$160 MW/h and solar/wind is 40MW/h. I can't see this equation working for intermittent renewables. Nuclear is so much more expensive, but when you factor storage, it is a drop in the bucket. This is accounting for all, including handling all nuclear waste. I cannot see the economical incentive to replace fossil with intermittent renewables, maybe we should be focusing on nuclear as a first step while we work on cheeper storage?

I'd use Zink Bromine. I have a lawn/area on my property behind my house, out of view, that lends it self for the purpose. I don't mind the density beeing low, when the rest seems to be good.

So far your Rust battery and Aluminum Air battery videos seem to present safe and most promising electric energy storage technologies. Also your video about nuclear waste batteries is interesting.

You forgot to mention that Lithium batteries for Grid Storage are competing for raw materials with the electric car industry! This will increase the inflationary pressure on them as the electric car industry scales up. It will probably be a LOT cheaper to use a different chemistry for Grid Storage applications like Zinc-Bromine than using precious Li-ion materials that are much more valuable to go into cars, delivery vans, buses and trucks!

One of the more interesting tangents this made me think of was the upcycling of older ICE related industries (car batteries) It made me wonder what other parts of the ICE engine production line could be converted. Like the people who used to make starter motors converting to making electric bike motors or similar... Not sure what a spark plug maker could be transformed into.

wally7 is correct, ICE will be with us for a while longer due to the energy density of gasoline. We can make synthetic fuel from nuclear power through pulling carbon out of the air, or continue using petroleum until the petroleum runs out.

How about the Edison Battery; the nickel-iron battery. They have low energy density, so the batteries are big, and a fairly high self-discharge rate, but in a fixed installation the fact they can handle unlimited total discharge, a wide range of temperatures, and a lifespan in excess of 50 years makes them appealing.

I have to say I really like the Gelion battery concept but I'm liking it more for home storage solutions. I say this because from what I've read about gravity battery systems. That's the way I think we should be investing more time looking into. But I also agree 100% with what you say. There is going to be, and has to be, a combination of solutions if we are going to do this right. Just like the tackling of the renewable energy situation. Oh, and love the video.

We don't want too many different technologies out there. What would be good however is a consortium that recommended a standard set of sizes and voltages. E.g. If a large car battery was one such size at a nominal 12v ., so that lead acid ws still allowed to play, then it would mean that companies would target that size as a replacement. Now inverter makers tweak the charging and input/output voltages of their units so they can adapt to a Standard Battery#3. The standards association would define a series ranging from a motorcycle battery up to units that required being placed with fork lift., each unit being something like 2-4 times the size of the next smaller one. Standard should specify foot print, hold down, terminal type and location. In this way when the Acme Battery corp goes belly up with their Uranium battey in 2050, I can replace their batteries with a different modular battery, retune my inverters, and job done.

Greetings from Australia, Matt, I'm hoping we're getting one step closer, en masse, to the up-take of renewable energy storage. However, If you have the time, space, know-how, climate and commitment required to do all the right things: harvest your own rainwater, grow your own vegetables, raise chickens, rabbits and ducks for protein, buy other necessities in compostable packaging, make bio-gas and compost from your garden and kitchen waste, have a chemical toilet and have no requirement for the utilities and services that are available you still have to pay "availabililty charges" for water supply, garbage collection, etc so local governments can get paid to do nothing. We are already paying hundreds of dollars each year to our local council for multiple bins to separate our recyclables but most of it still goes to landfill. We pay an extra 20c for recycling of bottles and cans to receive a 10c refund yet most of that still goes to landfill. It's all administration, pretense, fraud and corruption on a grand scale by bureaucrats to manipulate the green vote and keep their jobs. As we get closer to energy self-sufficiency at home I expect our corrupt governments will bring in unfathomable laws enabling an "availability charge" for power to prop up the poles and wires that they have sold or want to sell ("privatise") to foreign investors for billions of dollars that we, the people, will never see. Redflow and others: This would greatly hinder the up-take of home storage of renewable energy and the ROI on your R&D investment. Environmentalists: Wake up and watch this space. Governments: Don't you even think about it!

I LOVE 💕 these battery new technologies videos. As an electronic engineer, my dream since childhood is to create the eternal battery. This dream began when my toy's batteries were often dead. It should have some way to keep batteries to run almost forever, at least for many many years. And very compact. 💥💥💥

I have a VERY efficient energy storage battery: Water! Use intermittent electricity from wind or solar to desalinate sea water, and store the water in tanks or reservoirs for later use. The "energy storage" is the grid power you don't have to use to run the desalination. This technique is perfect for storing that energy because such a "battery" has no storage inefficiency. To increase the storage capacity, just make a bigger reservoir. Or use the empty ones we have now.

Great video of information and you sir are a great spokesman for your channel, very coherent and direct with factual data. I just liked and subscribed... Also, people while Matt brings us this ingenious technology, it is time to look into investing into some of these companies. Blessings and great health to all.

I think these Flow batteries have a big future as a safe fixed storage solution and would love to see Australia carry out large scale installation and trial of both of these solutions. If this works out we have a solution for flow batteries in fixed storage releasing the Lithium batteries for vehicles. This should bring down the cost of the batteries as there is another option.

You need an episode or a series of episodes to compare where some of these technologies are at. typical science sites explain individual technologies but rarely compare how close to reality they are. You see a technology and then never hear of it again. Did they get stuck on a particular problem or did some other solution seem more promising.

Our house backup UPS is AGM lead-calcium so this seems like a great fit here. Large-scale corporate UPS are often banks of flooded lead-calcium. Forklifts, scissor-lifts and long-life transportation seem like a fit too.

The Gelion batteries are poised to hopefully replace lead-acid applications, with a very real possibility of being a 1:1 replacement and not needing any advanced circuitry like Lithium does. I have also read that the RedFlow batteries can have the liquids recycled and essentially cleaned for re-use. They can also sit near indefinitely at any state of charge without the usual degrading. I was very keen to get one in a home solar setup, but RedFlow is pursuing the large scale market more than home (at least here in Australia). But still very exciting technologies!

It's another way of storing energy. Ultimately, there will be several options used, each chosen as being the best for the particular application. One newish idea is to store sand in an insulated container and use it as a heat sink to store surplus energy. The sand can be heated to several hundred degrees Celsius and the heat used directly or converted to electrical energy. Perhaps using a Stirling engine generator setup. This system is almost infinitely scalable, it uses cheap and locally available materials that don't degrade with use..

Curious. If they have the same format as lead acid batteries and so many more cycles, why hasn’t the automotive battery industry converted or already looking at this as a replacement for all the existing ICE and lead acid applications? If cheaper and more effective, it would seem to be one hell of a use case and existing market to upgrade.
