If it's out of calibration or otherwise not optimized, there's a chance that an iron air battery will produce hydrogen peroxide as an unwelcome byproduct.

Iron Air batteries would be really cool if the were scaled down for off grid storage at the small compound scale. 3 to 5 house holds. Or for that matter for decentralized storage. Lets say one lot in a residential neighborhood for every 20 regular lots. If you have solar, wind etc on your house. You charge your local grid before you send the extra back to the big grid. De-centralization should make the overall grid much more resilient.

I'm not _sure_ that would work. My concern is that these systems are slow to start up and slow to discharge, so I'm thinking that in a small neighborhood, energy needs would rise and fall quickly as one house's air conditioner came on and another house's toaster turned off, and I don't think that this sort of device could be that agile. On the other hand, if you have hundreds of homes being served, and they all _generally_ need a certain amount of power at a given time, then a large facility of these can rise up to _mostly_ cover that, with Lithium batteries or capacitors or other things handling the small "blips" along the edges of that massive wave. Now, maybe if each home _also_ had their own Li-ion battery to handle the spikes, that could work, there are options.

In the Netherlands we (Technical University of Eindhoven / Metalot / Rift) are also working on using iron as an energy carrier. One difference is that we combust iron powder in a reactor, creating heat and iron oxides. These oxides are then converted back into iron using hydrogen that is generated from renewable energy sources. Might be interesting for you to also take a look at this implementation.

@@marcusnichols5595 I was aware of this idea, and I am pretty confident, a high MW grid connection had always been appreciated financially, in contrast to what you think. Some projects even take it a bit further. They say that there is not only value in the grid connection itself (HV lines), but they keep the turbine and turbine shaft. This is a large rotating mass (rotating at net frequency speed such as 50 Hz or 60 Hz) that stores a certain amount of rotational energy by itself, and has a certain inertia as well as all the frequency transformation and control/stabilization aspects built-in to feed the grid. However they drive this rotating mass from renewable energy. Thus, they can make use of even more parts of the former coal-fired power plant. My point is to put risks and benefits into perspective: if you take over "too much" of the power plants, then you take over the need for power distribution as well. You may be faster to connect your renewable energy source, but it will be connected essentially at places, where there was coal. This is not necessarily, where consumers are, which are in cities, or electric power is needed near heavy industry. In addition, the location of the former coal-fired power plant can be a place with low renewable energy sources (like wind energy, hydro energy, biomass energy, sunlight). So, even if there is a good grid connection, it may still not be appropriate for several forms of renewable energy facilities. In essence good grid connection is only one property of a particular site. Your renewable ennergy sources should be nearby and strong. And your consumers should be nearby in order to not put billions and billions of dollars/euros in power distribution networks. Decentralizing power supply as well as decentralized storage and peak shaving have their own properties: risks and chances.

A short but excellent video that brings some good news to boost. Do update us when the storage facility will be online. Also, I am curious about combining this type of energy storage with construction of ziggurat style buildings to maximize the amount of storage per unit of space to reduce land usage.

Great news!!! Thank you for an episode about SOLUTIONS. 👍😀

Nice to know. It would be quite a good way to use the roof place as solar pannel array too.

I see the chance to stack your solar on top of the batteries as a strong plus for the cost effectiveness of the units (land costs is once, now twice). Another thought is stacking wind and solar on top. In another video, "Just Have a Think" covered a wind based power system that is for rooftops and is intended to be used in conjunction with solar. Combining these, your batteries are basement level (they are heavy), and your wind and solar are on top. Side transparent solar can then be used as windows for more energy collection. As well, use geothermal for building temperature control. The up front costs will be more, but the long term costs will be much less. I am amazed at how much progress has been made on electric (by any form) energy storage has progressed in the past 50 years as compared to all previous progress. Now, as society rediscovers old construction methods to regulate internal building temperatures more effectively and less expensively (as money or power), this aspect of our abuse of natural systems may actual start slowing down.

Iron-air sounds perfect for standalone housing and light mfg. I'd have one on a homestead, for example. Ship it in, set up a turbine, do something else for a week, and there you are, heat, cooking, light, hot water, machine supply. Expand as needed.

Brilliant. As always.

In many countries you have the situation that if you have a private PV system you get paid not very much if you deliver your power to the grid, but save the high utility rate if you use the power yourself. So maximising your self usage is key to profitability. If you can store your power over longer periods, this could potentially greatly improve the economics of pv systems. I can also imagine having two types of batteries that work together. Li-ion for intraday storage and iron air fir long term storage.

Thanks for the update. This iron air battery seems pretty cool to me, a lay person who still has trouble telling the difference between volts and amps.

Great channel. I really enjoy the content, especially when there’s positive news like in this video. Thanks.

I remember your video on this and how cool it sounded. I’m so glad you revisited this for us all. Hopefully we can all do something to help keep anything to fight climate change going strong

Appreciate the details and am looking forward to seeing how well it performs.

Great video! This going back is really something 👍 Thank you!

Yaay I am so happy this is moving forward!

Agree it’s really good to see some of these technologies (slowly) coming to fruition and this one certainly seems to make sense. What of solid state batteries- that’s the big one!

You are the best at this stuff.

Ah, simplicity is serenity. From solar straight to long term safe storage. no fires, no hazmat, recycling is easy and cheap.

Ok, this is exciting.

Glad to hear some good news 👍

Sounds good, cheers, Dave!

Thanks Dave - good stuff. I'm beginning to feel hopeful.....

That is great news! The climate needs it!! 👍👍💪💪

The earth doesn't care about iron batteries. She simply wants living organisms which contain iron.

Would be interesting to see a more detailed cost breakdown, the cost of the basic materials of an iron battery seem much cheaper than even LiPo so interested to see why they're more expensive at scale.

Cool technology that will make renewable energy available when needed, which solves a problem that renewable energy has. Thanks for keep us up to date on this important technology.

I'm honestly glad that you plan on actually covering both the good and the bad here. A lot of channels like these just seem to find "the future of energy storage" every week and, as always, they end up going nowhere, but they keep making videos anyway. It's fine if you see a project that could be big and is interesting, but people all too often seem to think there will just be some magic bullet that suddenly makes all the world's electrical problems go away. And I mean, there is, they just don't like it because they think it's dangerous and radiation is scawy. I still do wish more channels actually addressed nuclear honestly, given it's arguably the cheapest, on-par with or even safer than solar, (yes, including meltdowns) and pollutes 2-4x less than solar on a per GW produced level. But, if the focus *_is_* going to exclusively be on renewables, a more measured and realistic status update on how much progress has actually been made is the best way to do it. edit : P.S. while I am definitely more reserved on these sorts of things compared to I think most people probably watching, using spent-coal-fields for these sorts of things is actually quite smart given that that land isn't actually being used. One of the big issue with things like solar or most energy storage plants is just how much land has to be cleared for it, so using already condemned land is a good use for it.

I like that Xcl, my utility, is doing this now!
