Solar/wind + battery storage is cheaper than natural gas and a hell of a lot cleaner. It makes no sense to go for a more expensive, dirtier form of energy.
I’m excited about salt batteries taking up the slack on a lot of this infrastructure in the future.
Iron-air rust batteries are also pretty intersting. Just iron, air and water to store power by exploiting how rust forms.
anything that’s outside of rare metals batt technology either lithium or sodium based right now is basically off of the table, except for silver zinc iirc, and nickel hydrogen. Those are like the two options that are probably viable, everything else simply doesn’t exist yet.
They are a lot more expensive than expected at the moment, once they start selling at the 30$/KWh they were proposed at they will be fantastic but if they stay at their current price LFP is going to be a lot cheaper.
I don’t think that’s true, do you have sources for that? Because my understanding is that solar/wind is cheaper than natural gas, but battery storage makes it way more expensive at scale.
There’s a huge difference between day/night storage which is sufficient for most locations in the world that are somewhat closer to the equator, and seasonal storage. We have no good solution for seasonal storage at the moment.
Exactly. Day/night storage can probably be met (at least partially) by using EVs (i.e. arrive at work empty, recharge from solar, arrive at home full). But that’s not going to be enough to get through the winter in higher latitudes.
That’s why we need a reliable base load, and natural gas is very attractive because it’s:
- easier to build than nuclear
- way less polluting than coal
- compatible with existing supply lines
Battery storage is prohibitively expensive in many parts of the world, and there aren’t very many ready alternatives. I think we should be investing in nuclear power instead of utility grade battery backups, and we should be looking at EVs to help even out the day/night cycle.
What is your understanding based on?
Regarding production batteries might be more expensive, but they can be charged some thousand times without any additional cost
Just from looking at some government studies. This doesn’t necessarily compare longer-term costs, but it does give some direct comparisons between storage options.
I’m certainly no expert here, but just throwing out some rough estimates of battery degradation, it doesn’t seem to be cost-effective vs natural gas, which is already only slightly more expensive than solar. So solar plus battery storage seems to be significantly more expensive than natural gas.
It’s certainly more complex than that (i.e. you’d need less generation if battery backup is plentiful), but that’s the data I’m looking at.
Yah, downvote the guy for asking for sources for a baseless claim. I have heavy doubts that battery storage is anywhere near as cost effective as NG turbines. I’d love to see some real numbers on that.
And I say this as someone with a house running on batteries and solar exclusively.
I guess it kinda depends on how and where you source your batteries.
There was something in Australia I think that was using old EV batteries for grid scale power storage. As EV adoption goes up eventually old batteries will get pulled from vehicles, and reusing them for grid or even home scale power storage is a great use.
Sure, but that’s a) going to take some time and b) not going to be very convenient. Pulling something designed for a car (e.g. built in to the frame) and putting it into something for the grid are very different design spaces, so it could end up being prohibitively expensive to retrofit these car batteries into the grid system. Each manufacturer is going to use a different form factor, potentially different voltages, different cooling systems, etc. It’s probably easier to break down the batteries and remanufacture them than to reuse them directly for grid storage.
What I do think could be a huge boon is to use cars at rest as storage. A lot of people leave their cars plugged in all day at work (peak generation), as well as at night (no generation), which is a pretty decent fit for a base level of supply. You’d basically drive to work mostly empty and get home mostly full, and you’d get a discount on your energy bill for allowing your EV to be used for energy storage. I don’t know if any utility companies are using them that way, but that’s a fantastic way to get a bit more use out of EV batteries.
Solar/wind + battery storage is cheaper than natural gas and a hell of a lot cleaner. It makes no sense to go for a more expensive, dirtier form of energy.
How exactly is the production of batteries cleaner and cheaper than the production of natural gas?
In the US, the major source of natgas is now fracking.
And uh, fracking is about the most gross extraction method for anything you can dig out of the ground.
A potential solution here is to dramatically limit or eliminate protections for fracking, but still allow it. If they can pay for any damage they cause, they should be allowed to do it. The problem is that we’re subsidizing these efforts in a number of ways, and giving these orgs way too many protections. We should remove those, but IMO not ban fracking itself, since it can be a very useful way to produce energy in our transition away from coal.
That said, we should absolutely be investing in clean energy. I want to see a renewed push for nuclear power, expansion and optimization of hydro, etc. But we’re not going to switch to green energy overnight (and the US is improving on emissions faster than many other countries), and fracking works well in the short-term as we move away from coal. As renewables get built out, we can reduce how much fracking we do.
Cool story. How do we pull rare earth minerals, needed for batteries, from the ground?
You make the batteries once, and the pollution due to production is spread over the 10-15 year lifetime of the battery. During that time gigawatt hours of clean power sloshes in and out of them. This in contrast to having to produce enough gas to make all of those gigawatt hours once, then throw the gas away as co2 and get more, along with the attendant pollution.
Batteries have infinite energy now? No storage issues due to electrical surges, heat, cold, or anything else that makes batteries sub optimal? While seemingly by magic, mining rare earth minerals spreads its environmental impact over 10-15 years of the lifetime of the battery with 0 negative impact to the area the mine is located?
Oh wait… None of that is true so I guess you can try again.
Mostly because natural gas is a one and done thing when it is used. Batteries can be recycled. Production of natural gas is largely done through racking which destroys the groundwater. While batteries often require mining (excluding mechanical ones), they often can be broken down and reused in new batteries. And of course there is the greenhouse gas emissions from methane that are horrible. Methane is extremely leaky. Methane usage emits about as much greenhouse gas emissions as coal does.
I enjoy how much effort it takes to ignore how batteries are produced in order to argue for them in a comparison with natural gas.
Do you want the math or would you prefer less reading and more pictures?
Nothing like an ignoramus to try and make someone else feel stupid for asking a question.
Since you are all knowing, explain to me exactly how deep earth mining is less costly and better for the environment than deep earth drilling.
Or did you think we just magically pull batteries from thin air at 0 cost?
there’s not enough lithium on this planet to store enough energy for like half of europe nevermind entire world
you know how to do this the right way? use pumped-storage hydropower. need more? build more, then dump power into heaters (or better yet heat pumps) on demand from grid since fossil fuel heating will be replaced anyway. (we’re nowhere close to this, but it can sink a lot of energy quickly while not using it at some other times)
Pumped hydro is both very geologically limited and environmentally detrimental. That technology alone will not substantially reduce the need for other power storage technologies/ peaker plants.
Pumped hydro is both very geologically limited and environmentally detrimental.
If you are willing to live with the very considerable impact and are willing to do a costly megaproject, one possibility that I’ve raised before: it’d be possible to go implement Atlantropa, but instead of using it (exclusively) to generate hydroelectric power, as its creator envisioned, use it for pumped storage. The world will never need more energy storage than that could provide.
https://en.wikipedia.org/wiki/Atlantropa
Atlantropa, also referred to as Panropa,[1] was a gigantic engineering and colonisation idea that German architect Herman Sörgel devised in the 1920s, and promoted until his death in 1952.[2][3] The proposal included several hydroelectric dams at key points on the Mediterranean Sea, such as the Strait of Gibraltar and the Bosporus, to cause a sea level drop and reclaim land.
The central feature of the Atlantropa proposal was to build a hydroelectric dam across the Strait of Gibraltar, which would have generated enormous amounts of hydroelectricity[4] and would have led to the lowering of the surface of the Mediterranean Sea by as much as 200 metres (660 ft), opening up large new areas of land for settlement, such as in the Adriatic Sea. Four other major dams were also proposed:[5][6][7]
- Across the Dardanelles to hold back the Black Sea
- Between Sicily and Tunisia to provide a roadway and to lower the inner Mediterranean further
- On the Congo River below its Kasai River tributary, to refill the Chad basin around Lake Chad, provide fresh water to irrigate the Sahara, and create a shipping lane to the interior of Africa
- Extending the Suez Canal and locks to maintain connection with the Red Sea
Sörgel saw his scheme, which was projected to take more than a century, as a peaceful pan-European alternative to the Lebensraum concepts that later became one of the stated reasons for Nazi Germany’s conquest of new territories. He envisioned Atlantropa as a way of providing land, food, employment, electric power, and, most of all, a new vision for Europe and neighbouring Africa.
There are two very considerable issues there:
-
First, dropping the Mediterranean Sea by 200 meters is going to have a very large impact on the coasts of northern Africa and southern Europe. Sörgel considered that desirable, but obviously there are going to be a lot of people who don’t like such a change.
-
Second, if it’s permitted to build structures in this new area – as was originally intended – then a rupture of the dams would produce cataclysmic flooding; we would essentially have recreated the Zanclean flood:
Ninety percent of the Mediterranean Basin flooding occurred abruptly during a period estimated to have been between several months and two years, following low water discharges that could have lasted for several thousand years.[3] Sea level rise in the basin may have reached rates at times greater than ten metres per day (thirty feet per day). Based on the erosion features preserved until modern times under the Pliocene sediment, Garcia-Castellanos et al. estimate that water rushed down a drop of more than 1,000 metres (3,000 ft) with a maximum discharge of about 100 million cubic metres per second (3.5 billion cubic feet per second), about 1,000 times that of the present-day Amazon River.
The Royal Air Force bombed two dams in Germany during World War 2 to flood an industrial area in Germany. Russia just blew up a hydroelectric dam in Ukraine that caused a mess and water to drop upstream by 2 meters. If such a dam were to be attacked in a war like that, it would be horrendous. We’d be talking about a water depth difference a hundred times that and a far larger area.
EDIT: And a third, I suppose – if you take water out of the Mediterranean via evaporation and pumping, it will eventually wind up elsewhere, and we live in an era where sea level rise is already a concern, so it’ll cause sea level rise elsewhere. Would eliminate concerns about sea level rise for the Mediterranean, though…
at least it works at scale relevant to grids. there are other interesting devices that store high grade heat in things like molten silicon or sand, then convert it to electric energy again, but it’s rather at prototype scale now i think. power to hydrogen is fine if it’s replacing hydrogen from natural gas, but it’s wack for storage of energy
Lithium Ion is more advanced battery technology because it’s got high energy density which means it’s used in consumer electronics. Lower energy density technologies exist with better properties for storing at grid scale. They’re heavier and bigger than lithium ion batteries, but can store energy a lot longer and use much more available materials. One example is Form Energy’s Iron/Air battery, which uses rusting iron to store electricity for hundreds of hours.
there’s not enough lithium
I am hopeful that developments in sodium ion battery tech will yield different strategies. The weight and energy densities vs cost and abundance mean that it makes more sense (at this time at least) to reserve lithium ion battery tech for more mobile use cases like handheld devices and EVs, but use sodium ion battery tech for things like grid storage or home energy management solutions. I dream of a day in the next decade or two in which virtually nobody bothers to have a generator for emergency home power and instead opts for a UPS with inverters and chargers hooked up to a home battery, allowing not only emergency power, but a “smart” system to power the home via battery during high grid demand and charge during low demand, normalizing grid supply curves and making power bills cheaper for all. The path to this starts with big scale early adopters like hotels and apartment buildings, which could easily supplement energy needs through solar panels on their large roofs at the same time.
For all the enshittification we’re seeing across most industries, I am cautiously optimistic that we might be living at the edge of an energy revolution. We may see fucking huge fundamental changes to our energy infrastructure within our lifetimes, and that’s one of the few things I’m excited about for the near future. It’s unfortunate that it’s taking a crisis to force these changes, but it would be a great pivot nonetheless.
i think that in order for that to happen we have to change the way we think about energy. more of use it when it’s available, and less use it on demand
Sodium batteries are already being produced (only in one factory in the US and one in China so far but its a start to commercial production), there’s enough of that stuff to build batteries for the entire planet a thousand times over.
Didn’t realize we had sodium batteries being made in the US on a commercial scale.
there’s not enough lithium on this planet to store enough energy for like half of europe nevermind entire world
This is a good use case for sodium batteries. They’re less energy-dense so not great for vehicles, but for a stationary application like this they’re perfect.
yeah this is fine, but these need to run at high temperatures last time i’ve checked. that makes it a bit more complicated to use
There are plenty of alternatives for lithium batteries, chiefly sodium and a redox flow. Heating/cooling is good as well to store, but not every structure is energy efficient enough that it would make much sense. Good thing to work towards, but grid batteries would probably be faster and easier to implement. I have reservations towards pumped hydropower, in part due to watching how hard it is to decommission a lot of hydroelectric dams these days in US as well as the cost to create the areas to hold the water (a lot of the areas that are geographically advantageous for pumped hydropower tend to be nature reserves or national parks, soo…).
Since most energy is used for heat, storing it as heat makes a lot of sense, and there are sand thermal storage systems that can scale from single household to whole neighborhoods.
i have a sneaking suspicion that if 80%+ of energy is used on heating anyway then storing that heat at point of use and topping it up when excess energy is available is the easiest, least wasteful way to go
redox flow doesn’t have that much better energy density. granted, it’s great for long term storage, but it’s still not there, plus it takes stupidly large amounts of vanadium to run. there’s also zinc bromide flow battery but this one deposits zinc so it’s limited on one side
You know what pumped storage hydro is? A battery. Unfortunately that is not an option everywhere and takes up a massive amount of space. The space portion is not a huge issue for grid energy storage for the most part but it can definitely limit where you can do it and its capacity.
As for the amount of lithium available, there is absolutely more than enough considering it is one of the most abundant materials on our planet. Not that we need to use lithium for grid energy storage. Lithium is very high density energy storage which you are correct that is not a high priority for grid energy storage.
Basically there is no one solution for grid energy storage. There are mechanical batteries, medium density chemical batteries, and even “depleted” EV batteries. We just need to apply what is right for each particular scenario.
I’m not disagreeing with you overall. But I figured more info and context is helpful.
Of course, Li-ion batteries will never cover large-scale power demand. Not primarily because of lack of lithium, but because it’s a technology that scales far too poorly into the MWh/TWh scale, and has a far too short lifetime.
The battery tech we need for truly large scale storage is different from what we need for small, portable storage. Stuff like redox-flow batteries are looking promising.
There’s also hydrogen, with different storage methods being actively researched- from direct storage to using ammonia as a carrier.
The issue with using mechanical storage (like pumped hydropower) is threefold (off the top of my head):
- It has ridiculously low energy density
- Even after > 100 years of pumps and turbines, the power loss in a pump/release cycle is very high.
- It’s heavily limited by geography
I’m not saying pumped hydropower isn’t part of the solution: I believe the solution is that we need many solutions. I just think it’s important to point out that battery tech isn’t some monolithic thing, and that there are issues with pumped hydropower (and mechanical storage in general).
We put in 10kwh of batteries in Feb of this year with our solar panel installation. So I suppose I might be part that headline’s statistic. April was the last time we had a monthly electrical bill. Last month we ripped out our aging gas furnace and put in a cold climate heat pump. One week after we had the natural gas disconnected permanently from the house. Our cars are charged on sunlight. We’re doing what we can do de-carbonize.
I’m jealous! I’d love to do all those things to my house. Unfortunately, I’m priced out of homeownership in my area. So I rent and all the money I’d otherwise be spending on climate-friendly upgrades are instead financing my landlord’s wealth accumulation.
I’ll be the first to say de-carbonizing a home isn’t cheap to do (or the home ownership for that matter). I’m doing what I can by buying and implementing the de-carbonized solutions today to increase market demands driving the technology and solutions lower for everyone else.
Batteries and gas aren’t really comparable so I’m guessing this means batteries are expanded at a rate 10x higher than natural gas is being expanded, which makes sense because natural gas is such a mature staple that it doesn’t have that much opportunity growth.
Batteries are also not an energy source, but storage.
(Yeah I guess that’s technically true of all energy sources, but batteries are more like a tank than a consumable…)
Of course adding batteries to store energy from off peak renewables to ready them for the peak is the point of this, but I would point out I don’t think anything prevents charging batteries from fossil-fuel generated electricity. I wouldn’t be surprised if an economic equilibrium dictates this to be the case, even.
I think batteries will be highly valued equipment as a smoothing function to help reduce heavy load wear on any kind of generating equipment to help with peak loads, regardless of what’s charging them… possibly allowing fossil burning plants to run closer to a base load level at all times.
Per the article… Yes. Batteries are counted as a source by the EIA, not just the writer’s opinion. They can supply power on demand, so it counts. It doesn’t seem that gas is slow because it’s mature, but rather it’s just not as enticing. It says one single gas plant was added and provided just 2% of the increased energy production whereas wind was 7, batteries were 20, and solar was more than all of that.
Yeah my original comment here was a lot more breathy than it should have been. I’m not critical of the article it’s definitely uplifting and accurate. But I think new battery tech on the grid would see usefulness even if renewables weren’t inconsistent, but that’s a whole different topic I suppose.
This is even more impressive when you realize that in some regions of the country, power companies are adding zero renewables. TVA, the biggest power provider in the country, is all-in on natural gas, allegedly because its board members get incentives from natural gas providers and refuse to expand predicted demand with solar, wind, or forced geothermal.
