I wonder which is saltier, oil companies or the batteries.
It would be nice to see a price/GWh of this (along with running costs, it says they save 1 Million per GWh, how much were the running costs before!?), but any improvement in battery tech is definitely a good thing.
Also the size of the thing and what happens to batteries after they die.
But why US? Can't store fracking oil in there.
Finally something the EU can invest those 600 billion in. Or buy it, like lots of EU startups were by FAANG companies years ago. Tramp says it's dead tech, so it's ok.
I honestly dont care who develops these kind of technologies, because it will spread.
The impact of these products are too important.
This is big! Grid scale Sodium Ion battery technology is (on paper) the best candidate for cheap large scale electricity storage. The fact that this company is working on 9 pilot deployments mean that this will likely produce the real world results that the paper exercises promise.
There are SO MANY advantages of Sodium Ion battery tech for grid storage over everything else we've used so far (nearly all Lithium based).
Sodium Ion batteries:
The only downsides to Sodium Ion is that the batteries are physically larger for the same amount of energy stored (which isn't a problem for stationary storage), and the charging/discharging curves are not as linear as other chemistries (which again, isn't an issue because these are purpose built applications where the curves can easily be managed by battery management systems).
What about the environmental impact of degraded sodium ion batteries?
I'm not going to take sodium mining into account, as there are many ways that it can be extracted, with probably minimal impact, like salt evaporation ponds. I assume it's less destructive than building a hydro dam.
Would container ships be a good application? Or too heavy/large?
I would happily dedicate a corner of my garage for a big sodium ion battery.
Also, fun fact they can charge and discharge faster than lithium ion. Also, their chemistry doesn't lead to spontaneous combustion. Perfect for a house backup.
I think it's the fire thing that is really their killer feature. So to speak.
Can we make them from desalination plants, in part? Or no? I don't know the science for it.
Yeah, the brine is where various useful ions can be further extracted from. https://news.mit.edu/2019/brine-desalianation-waste-sodium-hydroxide-0213
I love this too, I just hope they don't use too much Phosphorous, because those reserves are limited too, maybe there are alternative designs once this gets going.
I'm really excited about na-ion, if commercial BMS circuitry was available I would already have some for a few home automation and sensing projects because of their low temp performance alone. But I'll have to spin up a custom implementation with an arduino or something and I don't have that kind of skills lol.
everything else we've used so far (nearly all Lithium based).
We have used water before lithium, and it isn't bad at all.
That much salt is not going to be good for blood pressure.

You're not supposed to eat the electricity
First off, you're not my mother.
I work for a controller OEM that builds the brains for managing these systems. It’s cutting edge stuff.
The part that controls/balances the discharge profiles, right? Because sodium batteries have a more non-linear discharge pattern.
