Startup Building Zinc-Based Alternatives to Lithium Batteries Granted $400M Loan from the US (popsci.com) 97

Popular Science reports that America's Department of Energy "is providing a nearly $400 million loan to a startup aimed at scaling the manufacturing and deployment of a zinc-based alternative to rechargeable lithium batteries."

If realized, Eos Energy's utility- and industrial-scale zinc-bromine battery energy storage system could provide cheaper, vastly more sustainable options for the country's burgeoning renewable power infrastructure... Unlike lithium-ion and lithium iron phosphate batteries, alternatives such as the Eos Z3 design rely on zinc-based cathodes alongside a water-based electrolyte, notes MIT Technology Review. This important distinction both increases their stability, as well as makes it incredibly difficult for them to support combustion. Zinc-bromine batteries meanwhile also boast lifespans as long as 20 years, while existing lithium options only manage between 10 and 15 years. What's more, zinc is considered the world's fourth most produced metal...

The U.S. Department of Energy also notes that "over time," Eos expects to source almost all of its materials within the U.S., thus better insulating its product against the market volatility and supply chain issues. While the Department of Energy previously issued similar loans to battery recycling and geothermal energy projects, last week's announcement marks the first funding offered to a manufacturer of lithium-battery alternatives.

MIT's article notes that Eos's semi-autonomous facility in Pennsylvania already produces around 540 megawatt-hours annually — and it isn't operating at full capacity. This new loan could boost factory toward full-power. The $398-million loan funds "up to four state-of-the-art production lines," according to the announcement from the U.S. Energy Department.

It notes that the technology is "specifically designed for long-duration grid-scale stationary battery storage that can assist in meeting the energy grids' growing demand with increasing amounts of renewable energy penetration." If finalized, the project is expected to manufacture 8 GWh of storage capacity annually by 2026. That is enough to provide electricity to over 300,000 average U.S. homes instantaneously or meet the annual electricity needs of approximately 130,000 homes if fully charged and discharged daily. The project is expected to create up to 50 union contractor construction jobs and as many as 650 new operations jobs when at full operational capacity...

Critically, Eos batteries are non-flammable and do not require active cooling to operate. The batteries can achieve 100% depth of discharge...

    What seems like the largest lithium deposit in the world was just found in the US. It looks to be enough to supply several times the entire supply of lithium mined everywhere in the world combined last year, for more than a century. Ironic that the US is also providing this loan I suppose.

        Not really, this is all about economics. Zinc–bromine batteries can't hold a candle to any kind of lithium-ion battery when it comes to energy density, including the non-flammable solid-state lithium batteries. The selling point here is low-expense which means it's competing with lead-acid batteries for industrial scale energy storage.

        If it were cheaper to use an extremely flammable material to store energy then industrial energy storage companies would use it. This is an economics issue.

        That is correct. Zinc-Bromine batteries are suited for power station energy storage, and not transportation use. So LI-ion batteries are not an issue as far as feedstock goes.

        My thoughts on all of this is that there is already a solution for stationary energy storage, the Nickel-Iron Battery. Its main features are it is tough as nails. It doesn't have the same energy density as Li-Ion, higher self discharge lower energy energy retention, but it is plenty good enough for things like overnight energy storage for solar powered systems, even wind if people are going to install them in places where it isn't always blowing.

        Regardless, yes, these zinc-Bromine batters should work okay.

        I've always thought that Li based batteries were not a good idea for grid energy storage.

        And the research is ramping up again for Sodium Ion batteries. And there is a lot of that stuff around. That would be a likely competitor for Lithium based batteries in the future.

      • We already have very cheap (lead acid) batteries for permanent/backup storage. I know many datacenters have entire banks of (open or sealed) lead acid batteries. The lifecycle is a lot longer, recycling is a lot easier. There are many things that make for very good batteries, the question whether they are more cost effective is thus dependent on the cost of (mostly vertical) space.

    • If the deposit you're talking about is the one I'm thinking of, they might have some difficulty getting it [boston.com].

      Regardless, lithium batteries are better suited to applications where weight and volume are important... which neither are in grid storage. Given the amount of grid storage we need it is nice, if not necessary, to have multiple technologies to choose from.

          We should be switching more of the stuff we currently make out of steel to aluminum anyway, especially the automobiles. Automobiles are the most aggressively recycled consumer good, and making the unit body out of aluminum means enormous energy savings by the time you have recycled it just twice. (You reach energy consumption parity by recycling it once.) Aluminum has the advantage that the recycled material has the same properties as the original alloy, so long as you separate it correctly — which can now be done cheaply with laser spectroscopy.

          • But aluminum is also a lot more expensive and more difficult to work with. Lots of cars incorporate aluminum, already. My car has an aluminum hood, engine block, head, transmission case, etc.

            Would it be "better" if more panels and support structure were aluminum? Yes- it would be lighter, much more corrosion-resistant, and lead to being more fuel efficient and perform better. But at what cost. Cars are already getting insanely expensive. If, for example, it added another $10K to the sticker price, it

              I believe steel is just as recyclable as aluminum.

              It is not. It gets harder when you recycle it, then you have to add stuff back in. Also the temperature you have to heat it to is much higher. It takes more energy to refine aluminum the first time, but like I said before, you reach energy parity once you've recycled it just once. And (again, again) we recycle cars very aggressively, so they are the poster children for use of aluminum.

              We often have trouble hearing ourselves.

              These metals have fundamentally different properties and are largely unable to replace one another.

              These metals have both things in common and differences, and aluminum can replace steel in some circumstances and not in others. You can rarely use one in place of the other without design work, but you can commonly use one in place of the other.

              All of your examples may be valid, and I'm not going to try to track down counterexamples; Why bother? We're talking about cars right now, and the truth is that virtually everything in an automobile but the fasteners and brake surfaces that's commonly made from ferrous materials can be replaced with aluminum, and already has been in many vehicles. The Honda NSX and Audi A8 prove that you can have aluminum vehicles with only cost drawbacks. But those cost problems only exist until you have the mass of vehicles to recycle, and at this point the R&D has been done to make even the subframes, engine mounts and such out of Aluminum and not "just" the body, every part of the engine but the crank and the running surfaces on the cams, the wheels, the trim, etc etc.

              While we're on the subject, a lot of the crap we commonly make out of plastic now could have aluminum cases instead — and some of it does and is better for it, which is how we know it's not only viable but desirable. The plastic's recyclability is limited in the best cases, but the aluminum can literally be recycled forever without losing any properties but those restored through heat treatment.

              Aluminum refinement is the problem area, but it continues to improve, and increasing the volume can only increase the rate of improvement. But once you've refined the metal and produced the alloy, the savings in energy alone mount rapidly.

              Did I ever claim that aluminum could replace all of our uses of steel? Nope. But it can replace a lot of 'em, and once the initial energy investment is made, the savings thereafter are dramatic. And the more of it we use, the cheaper it will be to recycle as well, because material won't have to be transported as far before sufficient quantity of like alloys is available. And it does take a lot of mass out of a vehicle, and lends itself to designs which are more predictable in a crash (like the tubular members in the front of the A8.)

                • There's no question that there's an up front cost to aluminum, but you have to get steel nearly twice as hot as aluminum during the recycling process, and aluminum is also cheaper to heat treat for the same reason. Recycle it twice and you've saved energy compared to using steel to build a unit body.

          The Energy Department issued its final rules for the program in 2007, along with a list of 16 companies that made the cut for to apply for its first round of awards, and Solyndra was among them.

          [...]

          Bush energy officials wanted to get the loan closed on their way out the door — it was listed as the first of their "three highest priorities through January 15." (Obama took office Jan. 20, 2009.) But the Energy Department's credit committee held things up for more analysis.

          [...]

          It noted Solyndra's project "appears to have merit." But the clock had run out.

          That didn't keep Bush from touting the loan guarantee program on his way out of office. On Jan. 6, 2009, in remarks on conservation and the environment from the Eisenhower Executive Office Building, he said, "We dedicated more than $18 billion to developing clean and efficient technologies like biofuels, advanced batteries and hydrogen fuel cells, solar and wind power, and clean, safe nuclear power. We're providing more than $40 billion in loan guarantees to put these technologies to use."

          Ultimately, the Bush administration program didn't finalize a single loan guarantee.

          So Bush didn't actually reject the Solyndra loan, they just failed to push it through before the Obama administration came in.

          F) Solyndra ultimately failed, on approx the date Bush Admin analysts predicted

          The issue isn't that Solyndra lost money, the issue is we knowingly flushed millions down the toilet as payback for campaign contributions. (See above timeline)

          No, the issue is that you've seemingly created an extremely misleading summary of events.

      • We didn't have to fund Solyndra to fund the other 23 companies under that program, they could have respected the prescient analysis tge Bush admin did when they assessed and rejected the application from Solyndra (BTW, Bush Admin analysts even correctly calculated when Solyndra would fail if funded!)

    I've been over their website. I can find that their basic battery is the Z3 and that it is supposed to last 6000 cycles at least with 88% capacity after 20 years. What I can't find are basics like weight, physical dimensions and capacity for the individual modules. Not to mention that there's no real indication of price either. There's a lot of marketing speak, and they are really enthusiastic about their large rack solutions, containerized solutions and their giant hangar solutions, but they don't seem to think the home market is even a thing. It looks like regular people can't really buy these. When they can, it will probably only be through middle men that mark them up like crazy and package them in some "solution" or another that negates any possible cost savings over lithium.

    I admit that's a somewhat bleak view, but it does seem like way too many new technologies are kept too closely held by the companies that develop them. Sometimes it seems like they might have more success if they just wanted to sell stuff.

      They're also starting up, chasing the big easy targets first makes sense. I still don't get it, because while a neighbourhood UPS that also manages line conditioning would be nice I really don't see power companies caring when their existing infrastructure keeps the money rolling in without any new infrastructure costs.

      • Good posting, and I agree with it.

        Home energy backup is already met for those without on-site renewables using generators that are a fraction of the cost and size. Of course, they are also loud, often smelly, and require some maintenance.... and fuel coming from somewhere (typically natural gas, gasoline, or diesel). But they also can potentially supply power indefinitely. Not just X hours.

        And if these newer batteries are much safer and cheaper, it will open up even more opportunities. Right now, the th

        • > Right now, the thought of mounting a lot of lithium to my garage wall is a bit scary.

          Especially since regular use will eventually short them out from dendrite formation, and they burn at 2000c which is well beyond the melting temperature of any material you're likely to house them in. Li-ion isn't a great technology for batteries you should expect some consumers will have in place and neglect for 20 years. In a car you'd typically expect that performance issues would have them replaced long before th

            An ejection system would be a pretty fancy solution. I think a better solution might be some sort of basement lined with refractory bricks and with a chimney. Or just use non-flammable batteries, like the ones in this article.

            • Effectively, you'd build a blast furnace around your battery pack, though you'd probably avoid feeding it fresh air.

              But the ejection system is WAYYY more fun.

          • I think I'd want a Li-ion home power system to have an eject button - have the whole thing roll out into the middle of my driveway where it's less likely to burn down everything around it.

            Could be problematic, living on a hill. "Eject the warp core"

            • >Could be problematic, living on a hill.

              I have one correction for you:

              "Could be problematic, living downhill from someone with this system". On the hill you'd be just fine.

I still don't get it, because while a neighbourhood UPS that also manages line conditioning would be nice I really don't see power companies caring when their existing infrastructure keeps the money rolling in without any new infrastructure costs.

        Exactly, I just don't see the power companies making that kind of infrastructure investment when there's no real consequences to them if they don't. Meanwhile, there's a definite home market out there with people who want their home power to be uninterruptible and are looking for a safe solution that won't cost an arm and a leg. Even if they're not trying to be off-grid or maximize use of renewable power, they may simply want their power to stay on even if there's a power outage. I think there's a definite

          Great, start a startup that uses recycled car batteries to assemble a racked battery solutions for the retail market. That's actually a good idea. Extracting virgin materials to build such batteries on the other hand, probably isn't environmentally friendly. Batteries are very dirty things to make, somehow people forget this.
          • by tragedy ( 27079 )

            While there's nothing wrong with that idea, it's probably not going to meet the required capacity, plus there are concerns about flammability, etc. The messiness of making a battery is not really comparable to the messiness of, for example, a fossil fuel powered generator. The environmental impact of all of these technologies is relative. Nothing is environmentally neutral to produce.

    • You can do a decent comparison from wikipedia information on the battery chemistry. It's basically got less than one tenth the energy density that lithium-ion has so there's no way this is going to be useful for any mobile application. And it would appear that the cost is 3-4 times per kWh than lithium which has you wondering what the hell is so great about it. That too is listed in the wikipedia entry and it's not that impressive which makes you wonder who in Washington is getting campaign funding out o

      In other words, you just revealed it's yet another battery breakthrough no one will remember in a year.

      There are dozens of "battery breakthroughs" we hear of every year. How many have made it and replaced batteries as we know it? None of them.

      In other words, these guys have produced a battery in the lab that looks promising. Likely they'll try to go commercialize it, run out of money and sell it to whomever is willing to buy the remnants.

      If it's truly revolutionary, then likely they'll attract funding and b

        This is definitely a niche technology anyway. It wasn't expected to replace batteries as we know them. Interesting detail about Exxon Mobil and the lithium ion battery. I think we can recognize that an oil company might not have much incentive to produce batteries that might be very effective at replacing fossil fuel in cars. So, as a possible example of active suppression, that might not be the best example of a technology taking a while to get to market.

  • Eosâ(TM)s batteries use a water-based electrolyte (the liquid that moves charge around in a battery) instead of organic solvent, which makes them more stable and means they wonâ(TM)t catch fire, Richey says.

    The one thing doesn't mean the other. They may well be the most fire-resistant batteries of all time, but lead-acid batteries with water-based electrolyte can catch fire if you deplete the electrolyte enough - the case is flammable. And the down side to water-based electrolyte is that it can cook off, especially in contexts with series-parallel arrangements of batteries.

    • Ahh yes, because a little bit of plastic or possibly even some hydrogen burning ( if your ventilation is shite ) from a lead-acid is the same as a lithium metal fire. Right. Got it.

      • So to be clear, you think burning plastic is great?

        I support (as I have said here many times) the banning of NMC Li-Ion batteries, because they are a combustion hazard and also contain cobalt which is not something you really want to be breathing either. We should only allow LFP or even less flammable and less toxic lithium chemistries (if they exist) since NMC offers little reward and has massive drawbacks.

      • > a lithium metal fire

        There us no metallic lithium in a rechargeable lithium battery. It's all in the form of salts and not readily available for burning. What burns in a lithium battery fire is the highly volatile electrolyte.

        • by sfcat ( 872532 )
          The heat of the fire causes the Li to come out of the salt and then it becomes volatile pretty much instantly and boosts the flame. That being said, it doesn't explode in the same was as a hydrocarbon or sodium for instance.

  • They seem to have a production cost deficit compared to other grid storage solutions, or they would be able to run at capacity. Building more production lines won't reduce their production costs much AFAICS. Not until they go bankrupt and default on all their loans any way, that could significantly reduce their production costs.

    • The point of a subsidy is exactly the same as that of a loan, or a grant; The government recognizes a need for X as a matter of national security and stability. X isn't going to happen any time soon because The Invisible Hand of the Free Market(tm) is busy masturbating the 0.1%, so government steps in with taxpayer money to try and make it happen.

That's one worker for every 200 homes, and if we put the fully-loaded of each worker at, say $90K/year (including salary, taxes, benefits, pension, etc), that's $450/house/year BEFORE factoring in the cost of the electricity, be it solar, hydro, nuclear, fossil fuel, whatever.

    Thier ZBM3 module, used as base component to build larger modules, is a 'small doghouse' sized unit, which stores 10kWh. eg. Their QuadPod can store 40kWh up to 12 kW. Long term, standby power, with no need for a reserved amount of power for battery conditioning. 100% power drain is possible, and encouraged.

  • The most interesting thing to me is the 100% discharge claim.
  • So apparently they make Zinc-Carbon AA batteries for extremely long term, low-draw use. They never get residue on the terminals so they're for ultra long term storage. I put them in my thermostat and they ran out after less than a year. I found out they have like 400mAH. So they'd be great in maybe a remote control for a TV or something. But the point is they work, they're cheap, they're environmentally friendly upon disposal, and they're for sale for a reasonable price. If someone cares more about price an
