Lithium-ion and iron-air will likely work in tandem, with li-ion handling storage up to 8 hours, and something like iron-air for longer storage. Lithium-ion for grid storage will likely use the LiFePo chemistry, which is mostly iron and phosphorous. Lithium in the long run won't be scarce, and Fe, P are abundant.

I am curious if there is a catch. I am wondering what the coulombic efficiency is, and C rate. If either one is low, that would give good reason why it's being used for stationary use only despite having an incredibly high specific energy. At 700+Wh per kg, you could easily build an electric plane. But that doesn't seem to be their goal at all. I have so many questions now. I will be emailing them soon. I want to get my hands on one!! Update: unfortunately I was correct. Around 50% coulombic efficiency, and very very low c rate. I couldn't find any exact figures but there are some lecturers that cover this. Makes sense considering how similar it is to nickel iron batteries. These may work for stationary use, but that's it. I can't wait to see how well they actually work considering how bad the efficiency is. Ahh well.

100% this... I'm tired of hearing of these all being grid-scale. 99% of all outages I know of (Only the big ones make the news) are "last mile", When it comes to the regular daily (there's always power out somewhere) outages, grid scale helps NO ONE. Grid scale needs to be only an interim solution where the infrastructure can't yet handle point-of-load storage or buffering. Sure, load the keep-out area of active or decommissioned nuclear plants, around coal plants, etc (already dedicated land owned by the power companies) and there is room around almost any sub-station for a few mega-packs but those need to be supplemental to last-mile storage. Having distributed capacitors is never a bad thing, but it needs to be the least-focused piece. The economies of scale definitely work for grid-scale, but is that what the battery and inverter companies want when they can gouge individual consumers at retail prices? Grid-scale requires large plots of land, buildings, building permits, large time-consuming projects that take months/years filled with not-in-my-backyard protests. Point-of-load provides jobs for many installers instead of a small crew, the permitting is spread out to local authorities, the projects go in much faster, and when you CHOOSE to have it installed, it's yes-in-my-backyard. If the power companies want to own and control the storage, our neighborhood also has in-ground transformers that could be deepened. An option they could offer would be to put their own version of the power-wall upstream of the meter, then if I want to install solar, they would still own the safety-disconnect aspect and can coordinate the neighborhood smart-grid to either assist the supply of the sub-grid or disconnect it completely if necessary. They could also just subsidize any home power-wall/solar installations and then charge/credit under a number of schemes - ie: excess energy generation is paid as credit towards the equipment lease or perhaps fixed monthly lease price (paid-off at end of lease) and the sell-back is credit

Generally, there's three issues with residential storage - cost, service, and regulation. On the cost side, all energy systems have some sort of support components - the 'balance of plant'. Even if it's just a box and a fan, the Balance of Plant for small systems tends to be very expensive compared to grid scale. Similarly, someone has to occasionally provide service to the battery. Residential scale service has a high entry barrier- even if it's just training new service techs, and few companies want to front that cost. Finally, is regulation. The grid is interconnected. In the event of a power interruption, a central premise of all utilities is that power is off at source. Batteries make the grid into 'electrified islands' that present risk to line repair folks so regulation requires automatic disconnect equipment, etc. That also costs a lot of money when you're talking about millions of little houses instead of a few thousand substations.

Sounds like power density is much lower than lithium-ion, hence the repeated mention of discharge over days? Did I miss a mention of a power density comparison ? Would still be a great addition to spread out solar and wind power over time

It might be interesting to see a direct comparison between Ambri liquid metal batteries (10k cycles with only 1% loss of capacity and very fast charge and discharge), iron air, solid state (half the weight no fire risk - Teslar & Toyota) and also don't forget the highly scale-able liquid air 'battery' (look up High View Co. UK). I can see one issue restricting the steel / air battery is the current heavy carbon footprint of iron smelting. Roll on large scale renewable H2!

This is a fundamental change in the game. The energy density is largely due to the fact that much of the anode reactant mass is in the atmosphere floating around the battery instead of having to be inside of the battery. This, and the metal flow battery, IMO shows much promise for mass stationary auxiliary electrical storage. The unanswered questions here is what is the durability of the battery, i.e. how many cycles can it take before needing new iron electrodes.

Maybe this could also be a method of... steel production - electrochemical reduction of iron ore to iron metal using the excess energy from solar panels? I heard, that for example solar power plants in Nevada must be turned off (partially) in summer, because they produce much more than is needed. So, maybe use this energy for desalination of seawater or producing something that anyways needs electric energy (like aluminum or copper). Or CO2-free steel. During steel production in blast furnace much CO2 is released, so with use of green energy we can have this process environmentally friendly.

Pokrec, Some solar panels may be off because they produce their power at the wrong time of the day for the grid's demand. Using such sporadic power is not practical for what needs to be a continuous process, it is not commercially viable. Steel is not made in a blast furnace, iron is and it needs the carbon from the coke used as fuel to make it into iron. It is not just a step in steel production but a valuable metal in it's own right.

But you are right, this would be impractical. Still it would be worth to think, if there is a process, that would be economically viable to use it using the intermittent solar energy to produce something useful.

The theoretical energy density of Li-ion chemistry is also in that neighbourhood, around 550Wh/kg. Still if such a battery stil only has an energy density comparable to Li-ion and even with shorter cycle life, it might still be the better option for EVs if it is cheap. Getting your iron-air cells replaced every year for $600 is still better than a new Li-ion pack that costs $10.000 but lasts only 8-10 times as long.

If the weight isn't prohibitive and an easily switched out car battery could be made from this that was cheap - then you just have 2 or 3 of them at home and switch the drained one out for one that is charged. This concept (not using this battery) was proposed before as a way to capture excess energy generated from windfarms during low need hours (at night) so that it doesn't get wasted. Building such cars on a large scale (which are powered by easily switched out battery packs) would then enable "gas" stations to provide charged batteries in exchange for the drained battery on long trips. Essentially you wouldn't own the battery or their cheap cost would make it similar to how people exchange empty propane tanks for full ones. There would thus be no need to wait around for recharging either at home or on long trips. But if the pack would be too heavy it would kill that application. Cheers!

From their patents, it appears that they use what amounts to a sponge or foam structure for the iron electrode, which leaves plenty of room for the oxide - probably Fe(O)OH - to form. I think they'd have to be careful to oxidize only a portion of the iron, so that the electrode itself doesn't collapse (and stop conducting), and if that's the case, they can only store a fraction of the theoretical charge capacity per kg of iron. Hence the vast number of cells in a commercial installation. They're not large, but they are going to be heavy things. Shipping-container-sized versions would be more economical but would have to be constructed on-site.

Surely “distributed” and shared power grids also need to be replaced - at least in part - by decentralised power production. Households with solar panels on the roof (& even some commercial properties) all using their own power + sending back excess power to the broader grid just make sense!? Imagine all houses had some panels on the roof and a small wind turbine or two. Then imagine the same on smaller commercial properties and roofs of shopping centres…. That must make a huge impact on dense cities. THEN you add this kind of exciting iron-air batteries and suddenly the worlds power grids can really change.

This is very cool. Not only can I see grid sized storage but also would possibly be a lower cost alternative for off grid applications. Washing machine sized batteries would mean some preplanning for intial install and possible replacement. Definately going to need a forklift.

It sounds like if this technology gets validated and can be built for $20 a kWh, you could have a 100kWh battery at a price as little as $4k or $5k including production profits and distribution. This would mean you can put an oversized solar array on your house and have 3 to 4 days or more worth of energy stored in case of rainy or cloudy days. But we can't underestimate the resistance something like that would face from entrenched utility interests with massive amounts of money and lobbying power. In the USA, that industry generates around $400 Billion dollars a year in a mostly monopoly protected sector. They are not going to abandon that money printing machine without a fight.

In reality, micro grids would be more efficient and more cost effective, along with more reliable since you can eliminate large part of the power transmission infrastructure. However, as noted, it is not in any company's interest to sell you a one time solution. They would much rather produce and store the energy, and then sell it to you on a continuous basis.

Serviceability can be done with access ports that double as storage space. For larger homes these things need to be more centralized, but can still be accomplished with a utility closet. I think local storage (and more importantly production) of energy is the only viable future this type of technology has. A global effort is a recipe for disaster.
