According to Datang Group, the power station can be charged and discharged more than 300 times a year.
Well, nice, but “more than 300 times a year” is definitely a weird goal to define or a weird metric to brag about, right?
I mean, what in it’s desig could be so critical that they wouldn’t just say ‘once daily’ or something.
Does it require maintenance days when no cells are operational?
Hopefully we can soon get one as home batteries to extend the use of solar panels. Because I don’t feel great about having a lithium battery that large in my house
the power station can be charged and discharged more than 300 times a year. A single charge can store up to 100,000 kWh of electricity and release electricity during the peak period of the power grid. It can meet the daily power needs of around 12,000 households and reduce carbon dioxide emissions by 13,000 tons annually.
Nice
Put one of these in every neighborhood please.
Check UK stories.
People leaving next to turbines hate them due to noise pollution.
Well, shit. Better not build sodium ion batteries then.
Doesn’t California have some insane battery too?
Yes, but that is Lithium-ion. These batteries are Sodium-ion which are better for the environment and can potentially be made a lot cheaper… It’s still pretty new technology so it’s not really in any consumer products yet.
Sodium batteries are already in electric cars many months ago
Also you could buy individual cells on AliExpress
Sodium batteries will not replace lithium in cars, as the density is too low.
It means the battery weighs more but contains less power.
For an EV, that wouldn’t work, as the heavier the car is, the more power it uses.
With sodium you will probably half the range of the EV, which is already low.
probably half the range of an EV
Many EVs have ~250 miles range. I need a quarter of that in usable winter range for my commute. If I could get an EV with 125 miles of advertised range (about half that in winter) for a third the price, I’d do it.
It’s not going to replace my road tripping car, but it could replace my commuter, which needs very little range.
Economy of scale matters, so does practicality. Which one is generally lasting longer per number of charges and what’s the long term viability of both given the time they were build and the available tech at that time? I totally understand the greater availability of sodium vs lithium. However, will it last? Last time I read much about it, reliability was weak, charge capacity over time dropped drastically, and failures were high. (It has been a couple of years, so things may be changing. )
Something new and shiney can be nifty, but past that, what is this? It seems like an expensive hood ornament that will rust in the rain. Lithium is expensive and toxic to mine, but so are all metals to some extent, and this has plenty.
It seems like it’s buying something 25% off on a $100 thing that won’t last well. Sure, you saved $25 once, but you’re buying 3 of them in the same time frame.
Nah. Time to reread, sodium is absolutely a viable tech now.
Yes. Last I saw they lasted for more charges and had similar capacity to lithium. It’s been invested into so much because it is viable.
Nice
Hell yeah
I can’t wait to see this headline again but about a bigger battery somewhere else
Nice. This seems to be the future that solves a lot of problems. Right now in Australia, we’re seriously entertaining building nuclear power plants for the first time ever, to provide base load power that renewables allegedly can’t. Large sodium batteries could help us avoid that.
Sounds like a way to waste loads of money and keep people on fossil fuels.
Must be way cheaper to build more batteries and build out inertia. (Would still need backup power at this point though).
Reminds me of Elon’s Hyperloop. Not intended to actually work, but instead be a distraction to deflate interest in public transportation.
It’s not just base load, turbines also provide grid stability. All the quick fluctuations as people turn things on and off are hard to load balance with solar, wind, or battery. A big spinning turbine has a lot of inertia. That helps keep thr grid at a constant frequency. As solar gets bigger and bigger we might need big solar powdered flywheel generators just to stabilize the grid.
Inverters could also provide “virtual inertia” which help to stabilize the grid frequency. However most of today’s inverters don’t have it, or it’s disabled.
This means we don’t need solar powered flywheels, which are inherently inefficient, we just need software (edit: and batteries of course) more or less.
Partially. Inverters providing virtual inertia is good but has the problem of still being active and reactive. It helps and is cheaper and more efficient than flywheels.
Flywheels and turbines however provide a very sticky frequency. They help out a lot with stability and give inverters time to respond.
Think balancing a stick on your hand vs anchoring it in clay.
If we take enough turbines off line we are still probably going to need some mechanical power stabilization no matter how inefficient.
But yeah I think we are going to see a blend using as much electrical and as little mechanical as possible.
Lol,
Batteries are perfect for load balancing.
Please, know your facts
Batteries can’t stabilise frequency. If the frequency changes too much, the grid will go down.
You literally need a giant spinning turbine for this.
It’s pretty basic energy engineering, and is not related to load balancing.
The LNP doesn’t have a legitimate interest in transitioning to nuclear power or they would’ve begun over the last decade or so that they were in power.
Instead they’ve proposed - now that they’re in opposition - a technology which is banned at the Federal level and individually at the state level, because they know that gives them years of lead time before they ever have to begin the project.
On top of that, all of the proposed sites are owned by companies who’ve already begun transitioning to renewable generation or renewable storage, and most of them are in states in which the state Premiers have publicly stated that they will not consider overturning their bans on nuclear power.
The draw-back with sodium batteries needs to be known, because they won’t replace lithium anytime soon.
The density is lower, which is a great problem in EVs.
Not trying to be negative, but for an EV, or anything handheld, you get more weight for less power. Which is essential in a car, that uses more power the heavier it is.
What sodium IS the best at, are use cases where weight and size doesn’t matter. Like with battery farms.
In this case they are much better than lithium.
While you’re not wrong, sodium batteries coming on the market have 200 Wh/kg. This is comparable to where LFP batteries were a few years ago. That means the newer sodium batteries are about as good as what’s in lots of EVs right now.
The ceiling is going to be lower than with lithium. Sodium ions themselves weigh about 3 times more than lithium, for the same +1 charge. So it’s not just that sodium is a certain number of years behind lithium. It’s that it’ll likely plateau at a point permanently behind where lithium will likely be.
But for static storage, only price/kw matters.
Price per kw and price per kwh stored. And price per kwh over the expected lifetime of the battery itself (longevity and reliability and safety and disposal will have to be factored into total cost of ownership).
Still only price and kw. 😤
No, kw (power) is a fundamentally different unit from kwh (energy).
Energy is conserved, so that’s how we use it and pay for it, but power capacity is very important for infrastructure. A battery that can hold 1 GWh worth of energy, but can only output it at a rate of 10 MW, might have a ton of limitations to its usefulness.
Sodium could easily replace lithium in EV applications if people would acknowledge that only 2% of trips are more than 50 miles. Though it’s probably moreso the auto industry’s fault that people have this assumption they need to prepare for a three hundred mile journey on a moments notice.
If manufacturers were putting out cars that had four figure price tags with double digit ranges, they would become the best selling vehicles within a decade and no one would care if it was sodium, lithium, or sawdust. Of course, there is less profit to be made from smaller vehicles and so the corporations won’t bother.
EV owner here. 50 miles is not practical, beacuse then I need another for the other 2% of trips that are longer than that. This also ignores detours or traffic jams, when google will try to reroute me over a longer, but faster route. Plus, the “50 miles” readout you get is always just an estimate and the real range depends on temperature, driving speed, start-stops and how much elevation you need to cover. Some 30km trips here cost me 50+ EV km because its all uphill in one direction. I usually add 30km to my trip as required charge, because when the battery reaches 25km the car starts to complain with a nervously blinking battery readout and a “Charge now!” message on the dashboard.
“But then you just charge during the trip!” - Well this only work if i go somewhere where i know where to find RELIABLE chargers. I am well aware that there are good apps that show me charging locations, but getting a charging spot I can actually use is a different story:
- charging station can be used by someone else, or there is queue and each car will most likely charge for 30+ mins. Of course, sometimes some inconsiderate pricks will hog a spot untill their car is fully charged, even if it takes his frikkin tesla 2h
- charging stations close for repairs, sometimes for weeks
- some charging stations need an account or RFID-tag before you can use their (but not other) charging network
- other charging stations require you to bring your own cable
- some charging stations dont have the connector you need for your car
- some stations on the map are bogus, for example that one at my local volvo dealership that only exists to charge the showroom and customer cars, but is not accessible to the public.
Not saying EVs are bad, but the charging infrastructure still needs some work to be reliable and accessible. Petrol stations always have some large, obnoxious signs on the side of the road that you cant miss; Charging stations are sometimes just a tiny grey box on a wall and a 5-space parking lot, or behind a building and you never notice it when driving by.
A lot of households, like my own, have multiple cars. We have a commuter (50 miles round trip) and a family car. We use the commuter for most trips around town (only commutes 2x/week), and the family car for longer road trips.
I don’t need a car that can do both, I just need to replace the commuter since that’s where the vast majority of our driving is.
Don’t try to solve the hard problem of putting charging stations in the middle of nowhere, solve the easy problem of replacing that second car. For that, sodium-ion is more than sufficient. Focus infrastructure improvements on apartment complexes, workplaces, and shopping centers so people who don’t have a garage can charge.
That’s assuming you don’t have issues charging at where you live, which is a pretty big if for a lot of people. A 300 Mi charge would mean if you can’t charge daily, you would be able to go a couple of days without having to do so.
A 300 Mi charge would mean if you can’t charge daily, you would be able to go a couple of days without having to do so.
Given most trips are less than 3 miles, if you had a 300 mile range vehicle, that’s about three months of average driving, not a couple of days. My point was that people don’t go on long drives the vast majority of time and don’t more than fifty or so miles of range.
I’ll use Tesla as the example here only because it’s the prominent electric car brand. Directly from them:
A 120 volt outlet will supply 2 to 3 miles of range per hour of charge. If you charge overnight and drive less than 30 to 40 miles per day, this option should meet your typical charging needs.
They go one to say you can get a 10x improvement on the miles per hour when charging from a 240v outlet. Even accounting for installation of a new outlet to the garage or side of the house, this would be far cheaper than buying a vehicle with hundreds of miles of range and using a supercharger every other week.
