Yeah, I think massive chemical batteries for storing excess electricity to facilitate a contrived green energy market is a bad idea.

      As someone living in Texas presently: you could have saved yourself a full sentence:

      This is a shitty Texas-based company cutting corners…

      to

      Texas company

      or honestly:

      Texas

      Would be sufficient. Any Texan that doesn’t own x texas-based-company is tired of that company’s bullshit. It’s one of the few things natives and transplants agree on.

        We can all agree on that, Clearly li-ion is a bad choice for static use cases.

        But right now it’s the cheapest option, and it looks likely that will stay true for quite a while unfortunately.

              You can draw an arbitrary line of density you find good enough. But with how much space us wasted in some countries, that line should vary a bit place to place

                With 40 foot containers providing utility or smaller scale storage solutions of 2.9mwh per container with LFP batteries, that is about 170mwh per acre. Before stacking. I don’t believe a lack of density matters anywhere in the world. Spare space inside buildings is usually sufficient for building needs.

            Weirdly it’s not, except maybe gravity batteries where nice reservoirs happen to exist already. It should be but it’s not right now.

            Li-ion has economy of scale right now. I do think molten metal etc will overtake eventually, but they’re currently playing catchup and li-ion has dropped in price so much over time that it’s surprisingly cheap even where it should make no sense.

    So uh. I guess those coal and natural gas power plants would fare better in a fire. Something seems wrong there but OP clearly wouldn’t possibly post something on the Internet that was utterly detached from reality.

    Energy storage is just that. Fire is frequently quite good at releasing said energy.

    Lithium? poof.

    Oil? yup.

    Nat gas? mmhmm.

    wood? yup.

    Coal? dang.

    Guess all we got left is water - I’m sure that doesn’t have any specific regional requirements…

    So tell us champ: what energy storage you got all figured out from that armchair?

        I imagine you, like many, just don’t understand the insane engineering feat that is an electrical grid. Everything is realtime - Every time someone’s AC kicks on the grid must adapt and provide more power immediately. Power storage is a godsend to this process and in terms of relative age … is very new. With regard to power storage - there are very few ways to hold it that don’t run some risk of fire or other calamitous failure mode. That includes water - but I was being coy when making my statement implying it wouldn’t burn.

        To your comment: you could use salt/sea/undrinkable water for energy storage but it comes with regional requirements (elevation change typically) in addition to the water. It’s not one size fits all and definitely doesn’t work in many regions.

        Regarding your two options which you offered to create potable water (not to store energy:) Both are wildly inefficient and have one or more major drawbacks to them. Topically - one of these drawbacks is their massive energy requirement. So you provided a way to burn energy faster - not store it ;)

          If we build out our GHG-free power capacity beyond our electricity demand, efficiency isn’t an issue. We need fresh water. We need hydrogen and oxygen. I’m sure there are other convenient things to produce whenever electricity demand falls off. These energy storage and reselling schemes are just destroying value.

            We have sufficient generation. It’s a question of cleanliness, efficiency, and consistency. Consistency comes with storage and enables cleaner methods, while inconsistent, to be used.

            Using your example: what need do we have for food storage? We have grain right now - and we’re growing more! Who needs water storage - we have wells!

            Hydrogen and oxygen? Yeah we have that. What technology, currently available, are you suggesting we all switch over to, again? While I’m at it: last I checked stored hydrogen and oxygen have a tendency to uh… burn… and very “energetically.”

            You seem fond of the tin foil - you are apparently worried about “big lithium” or some such… wait until you hear about “big energy.”

            If you are genuinely posting and not acting in bad faith I imagine you need to broaden your view a bit.

              I’m not sure what you mean. Natural fresh water supplies are stressed in many regions. We need hydrogen to fuel vehicles and for the production GHG-free steel and fertilizer. Oxygen of course is necessary for medical and industrial applications. Safely handling hydrogen and oxygen is a solved problem and these gases are not polluting if you have to vent to atmosphere. It only makes sense from a wasteful, financially extractive perspective to store extra electricity by environmentally questionable means instead of actually using that energy right away.

                Hydrogen electrolysis is great, but its something to do with “too much” renewables, and also supports having too much batteries, which are more convenient for daily electricity needs from renewables, but also using up high battery storage capacity every day.

                We’ve been talking about energy and energy storage up till now. You’ve been mostly ‘on track’ with said responses up till this point - albeit overly generic and somewhat disconnected from reality… In the last couple responses you’ve jumped from water care to what I can only imagine was the first two Google results when looking up hydrogen / oxygen paired with energy.

                Is the other guy okay or did his shift end?

                Look. Here’s a sobering bottom line: if it were technologically feasible to “replace batteries” we would have already. Hydrogen powered x isn’t functionally acceptable because:

                a) It stores like shit.

                b) boom (pressure or rapid combustion - take your pick)

                c) It is shockingly (hah) hard to get oxygen and hydrogen to split efficiently. Very few sources of hydrogen are actually energy positive or more efficient than what we already have in more convenient, safer, higher density forms.

                I’m all for progress… but armchair warriors that claim the “moral high ground” by shitting on what works currently - while not being able to provide a single other suggestion beyond what they got drip fed from their feed and distilled by their echo group chamber need to sit the fuck down. Want to “stick it to big battery?” Go back to landlines. Put a crank back on your car. The list goes on.

                I digress. Back to energy storage: if you’ve got some brilliant solution - get to it. We’re waiting.

    This is why you don’t use battery chemistries that can thermally run away autoignite in grid storage. The plant was using LG JH4 batteries, which use an NMC chemistry. I don’t think that LiFePO4 cells were as ubiquitous when this plant was first constructed, so the designers opted for something spicy instead.

    This shit is why you use LiFePO4. It can’t thermally run away autoignite, it lasts longer, and the reduced energy density doesn’t really matter for grid storage. Plus, it doesn’t use nickel or cobalt so the only conflict resource is lithium.

    EDIT: LiFePO4 batteries can enter thermal runaway, but they can’t autoignite.

      Mechanical energy storage, like pumped hydro or flywheel. Thermal energy storage, like molten salt.

      Electrochemical isn’t entirely off the table either: less-volatile chemistries are available, and better containment methods can reduce risks.

      Non-electrical chemical storage methods are available: electrical energy can be used for hydrogen electrolysis, or Fischer-Tropsch hydrocarbon fuels. Fuel cells, and traditional ICE generators can recover the energy put into those (relatively) stable fuels, or we can export it from the electrical generation industry to the transportation industry.

      There’s also avoiding (or minimizing) the need for storage at all, with “demand shaping”. Basically, we radically overbuild solar, wind, wave, tidal, etc. Normally, that would tank energy prices and be unprofitable, but we also build out some massive, flexible demand to buy this excess power. Because they are extremely overbuilt, the minimal output from these sources during suboptimal conditions is more than enough to meet normal demands; we just shut off the flexible additional demand we added. We “shape” our “demand” to match what we are able to supply.

          Find an engineer or an engineering channel to better understand the grid. Energy generation - clean or otherwise - has to be adjusted in realtime… further: the above statement doesn’t clearly understand or solve for over generation vs under generation. There’s a fix: a reservoir. In other words: storage. This (storage) is present everywhere from the grid to almost literally every circuit board.

          You’re picking a fight with batteries/energy storage - then making an argument about something unrelated. “Storing cooked beef sure is hard” is not properly solved with “the store stocking more beef.” They are tangentially related… but not the same thing.

            further: the above statement doesn’t clearly understand or solve for over generation vs under generation.

            Filling a reservoir during the day to run a steel mill overnight is a complete waste of a reservoir: move the steel mill to daytime hours and you don’t need the reservoir.

            And yet, we are doing this now: We are driving consumption to overnight hours that can’t possibly be met by solar. We are offering cheap “off peak” power, and incentivizing overnight consumption.

            We do have good reason for it: we need that excess overnight demand to improve the efficiency of our base load generation. But, those same incentives are killing solar/wind efficiency and artificially increasing the need for storage.

            Yes, we need storage to match the imbalance between generation and demand. But it is far more important that we minimize that imbalance first.

            Shifting demand to time of production (demand shaping) is much more efficient than shifting production to time of demand (storage).

            OP’s position is rather ludicrous for a number of reasons, but they are not wrong on this particular point.

              This is just factually ridiculous.

              Filling a reservoir during the day to run a steel mill overnight is a complete waste of a reservoir: move the steel mill to daytime hours and you don’t need the reservoir.

              This isn’t a logical comparison. Here’s an apples to apples: It’s the rainy season - my plants have water … I take excess water and keep it in a rain barrel. An unexpected dry spell occurs: My plants have water.

              We’ll return to this in a moment.

              And yet, we are doing this now: We are driving consumption to overnight hours that can’t possibly be met by solar.

              Being night I’d imagine that’s a tough fight for solar… I’ll give you that. 🙄

              …But, those same incentives are killing solar/wind efficiency and artificially increasing the need for storage.

              No.

              Storage - or a buffer if you will - is simply a requirement of many systems. Electricity is no different. Renewables benefit substantially by having it and would be horribly inefficient without it.

              …Shifting demand to time of production (demand shaping) is much more efficient than shifting production to time of demand (storage).

              Demand shaping when we’re taking about the grid is largely the result of seasons, the availability of light, and our day to day actions. We turn lights on at night, the heat on when we are cold, and the air on when we are hot. We cook meals before and after work. Demand shaping on the scale that is being suggested requires a positively insane amount of change and has an infinitesimally small chance of occuring.

              Now: we have solar during the day and turbines for when it’s windy. This is your production. You cannot shift it. It is raining - my plants are getting water. How then, do you water your plants when it is dry? This answers itself.

              OP’s position is rather ludicrous for a number of reasons, but they are not wrong on this particular point.

              Op believes that energy storage shouldn’t be necessary. At all. They have clearly stated elsewhere that their opinion is not based on research and it shows. A grid requires a buffer - or a series of fast acting production which effectively simulates one. Solar / wind without that buffer would be nearly unusuable.

              Op is misguided at best and while technically not completely wrong: for them to be right we’d need to live in some utopia with vastly different technologies that we have presently. I like sci-fi too… but I’m not going to lobby congress to get rid of planes in favor of teleporters.

                Yes, that is one of the ludicrous arguments that I acknowledged OP is making.

                Storage - or a buffer if you will - is simply a requirement of many systems.

                Agreed. As I said: “Yes, we need storage to match the imbalance between generation and demand. But it is far more important that we minimize that imbalance first.”

                Demand shaping when we’re taking about the grid is largely the result of seasons,

                No. You are describing one type of demand shaping, but it is not the only one, and it is not the type I am referring to. “Time of use” plans are another type that consumers are more aware of. I’m referring to the industrial version of TOU rate plans.

                I am saying that these varieties of demand shaping are currently setup to support traditional nuclear/coal baseload generation, rather than solar/wind. They are currently designed to increase the minimum, overnight load on the grid. They are currently used lower peak demand, and raise the trough.

                Those TOU plans need to shift to driving consumption to daylight hours: To maximize the amount of power consumed as it is generated, and thus minimizing the need for storage.

                for them to be right we’d need to live in some utopia with vastly different technologies that we have presently.

                Only if we are trying to get every consumer to participate. We don’t actually need to do that.

                This is just factually ridiculous.

                Filling a reservoir during the day to run a steel mill overnight is a complete waste of a reservoir: move the steel mill to daytime hours and you don’t need the reservoir.

                This isn’t a logical comparison.

                Dude. We are already doing exactly that. We have grid storage facilities being charged by solar power during the day and discharging overnight. We also have steel mills and aluminum smelters paying lower rates to operate overnight rather than during the day, to meet the needs of baseload generators.

                But ultimately, the solar, nuclear/coal, storage, and steel plants are all on the same grid. So we are, effectively, doing exactly what I said: running the steel mills with stored solar power. Yes, there are legitimate reasons for doing it this way, but those reasons are ultimately based on legacy issues.

                To continue the shift from traditional coal/nuclear baseload generation to solar/wind, we either need enough storage to run the steel mills overnight, or we need to shift the mills to daytime operation.

                Again: Storage is important, yes. But, demand shifting is far more important.

                  I’m going to preface this response with: I will be consolidating / paraphrasing your responses I quote - I do not intend to misrepresent anything you said - it will simply be to manage post length. I have read your post in its entirety and am responding as such.

                  Yes, that is one of the ludicrous arguments that I acknowledged OP is making.

                  Consider that OPs statement used a LOT of the same language and recommendations but was horribly off base. I was re-asserting the fault in his views to remind you that he was - without question - completely wrong. This doesn’t mean that you are. It does mean that you shouldn’t give him a pass because he expressed interest in a solution you support. If anything this is a teaching moment where you confirm that he, is in fact wrong, but this is how x works.

                  With regard to storage…

                  I’m glad we see eye to eye on its presence in a working solution. Please understand that this has largely been the contentious point throughout the thread so this is where I focused when you asserted that OP wasn’t wrong in (even a particular) capacity. It needs to be clear so information isn’t misrepresented.

                  With regard to Demand shaping …

                  This is my view coupled with some basic knowledge of how things work - with a healthy dose of extrapolation: that is to say this response is opinion and not an area of expertise for me… but is where things logically ended up with this particular subject.

                  I understand the focus you are taking with demand shaping - but from my perspective I do not think the net result will be as great as you believe it to be… but for tangentially related reasons. Before I get into the meat of that - yes, I wholeheartedly agree that optimizations in any form are a good thing. Many gains in the field of energy generation and storage are measured in small steps so ~2-5% still matters.

                  With that said:

                  Generally speaking price/kWh is determined by usage overall at that time… Now factor in that these industrial factories you are moving are contributing to the current price (at their current time slot) - which is lower than where you want to move them.

                  A couple things to consider:

                  • Assuming their usage is significant enough to move the needle: (at scale) most factories would then have their workers on a standard workday as well. Remember that 2nd/3rd shift workers are probably sleeping through at least 1 of the “peak usage” periods which in its own way is also offsetting demand. This in all probability would be a dampening effect on the shift that would be expected from the primary “move.”

                  • Assuming no major effect from the workers changing schedule (which based on my understanding would not be the case) - and indeed a sizable move from the factories proper… you’d still need the factories to be willing to take on the increased energy costs associated with moving into the more expensive energy window. While this is the “ideal” you are looking for: This feels… unlikely. (see utopia comment)

                  With regard to peaks and troughs:

                  I believe we both agree that storage is a necessary component of most solar / wind installations. Presently (to my knowledge) most battery systems are used primarily as a “smoothing” buffer for incoming energy as neither sun nor wind are constant resulting in variable returns. Secondarily, they function as a substitute during extended periods on non-generation (nighttime.) Now these battery systems are going to exist regardless what usage is occurring when - they exist to make the solar/wind systems reliable and efficient.

                  Lets factor in our constants:

                  • Energy generation: The sunlight isn’t changing nor is the solar installation’s size. Daytime generation + nighttime generation should not change functionally at all here as (to my knowledge.)

                  • Daily energy: this should not change - the factories continue to use “roughly” the same energy as before.

                  Functionally this solution isn’t changing how much energy is in the system, nor is it changing energy consumed. It may be changing how much the batteries are cycling… which, sure, would be an environmental impact… but not production. To resurrect my rain example: we haven’t changed the barrel size, the rain amount, or the plants that require said water. We’re just changing when we water them.

                  Dude. We are already doing exactly that.

                  (This is loosely referenced knowledge - but it passes the sniff test:)

                  Making the change you and OP are referring to works in a bubble but not in the way you are envisioning it. Presently at least. A grid, as you observed, is a series of power stations working together to provide the sum of energy required. The grid, as I asserted earlier, is very exacting in its requirements to function (pressure system example.) It stands to reason that the intermittent producer be locked to a rate they can “safely” achieve based on averages and their storage capacities. They will not be the first pick nor the lions share of “reactive energy” provided. We can’t produce more “sunlight” without robbing Peter to pay Paul - a battery dump during the day to assist with reactive energy results in less energy to provide at night. This system is optimized and sized for a set “average” generation during the day with an expected offload at night. (rain example again)

                  So who picks up the slack for the move to prime hours? You provided that answer:

                  But ultimately, the solar, nuclear/coal, storage, and steel plants are all on the same grid.

                  So yes, the shaping could move demand into the peak hours - and then would re-apply stress to the exact producers that the mills were moved originally to relieve. This feels like a non-starter to me: Task failed successfully …at least in our current conditions - which leads us to:

                  Again: Storage is important, yes. But, demand shifting is far more important.

                  Absolutely using solar to offset steel mill energy consumption is an outstanding concept - but it requires build outs, regulation changes, and a lot of different parties to agree to make that change. I may have been hyperbolic in my utopia / teleporter examples but the point is: those changes are neither quick nor easy and may as well be the stuff of science fiction for now. I agree its important to phase out legacy producers like coal / oil - I firmly believe nuclear is here to stay until it is replaced by the next “big” producer. Will renewables eventually be our primary source of power? We see examples of it working - so sure. Its possible. But renewables will continue to be a package deal with storage. The technology may change but the storage requirement will remain constant. (This part is, again, aimed at op- not you.)

                  Final thoughts: I spent far longer on this than I anticipated - but I think your post warranted it. You provided facts to the best of your knowledge and clearly were compelled to state the case for something you believe in. Ultimately - I wouldn’t say we disagree: I think we are both looking at different time horizons. Currently, in the here and now, your solution isn’t readily available nor easily achieved. That said- it is clear that at least some people are seeking what you presented as an eventuality. ~10 years from now it may well be reality. I still believe that you shouldn’t have defended OP’s position as you did. A partial affirmation likely will be received as “Oh, see! I was right- mostly…” and they will carry on; learning nothing.

      Abandon the model of buying and storing electricity when demand is low and reselling power back to the grid when demand is high. Instead, electricity should almost always be generated in excess of demand with the difference going to hydrogen and oxygen production for various medical, industrial, agricultural, and transport applications. If we ever run out of storage, they can be safely vented to atmosphere.

        Before you can can do that, you need enough renewable generation capacity to exceed peak demand. And of course that will never happen because of the bottomless appetite of AI and bitcoin mining for electric power.

          We need an authoritarian figure to nationalize the energy supply, shut down these wasteful expressions of late stage capitalism, mandate rooftop solar, and build out our nuclear fleet.
