Peak Energy just shipped the US's first grid-scale sodium-ion battery

  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:

  • don’t have as intense thermal management needs Lithium chemistries
  • don’t have the massive negative environmental impact for their source materials (because its a part of regular old table/sea salt)
  • doesn’t have the massive swings in capacity when operated in extreme hot or cold temperatures. Sodium Ion doesn’t care.

  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).

    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.

    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 are extracted from.

    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.

    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.

    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.

      Not so great in a flat dry desert though. Pump storage is great when there is lots of water and a naturally occurring elevation, but there’s lots of places on Earth that don’t have that, but do have energy to store.

      Pumped hydro?

    Would container ships be a good application? Or too heavy/large?

  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.

    • Cocopanda@lemmy.world ⁨2⁩ ⁨days⁩ ago

      It is what controls when to inject back up power to shave peak power, the brains to know when to use the grid when it costs the least and then it knows when to balance the solar with the back up to shave peak power.

      Check us out at Ampra Grid. It’s not for residential use. Mainly for massive industrial use. Msrp of about 19,400$.

  I wonder which is saltier, oil companies or the batteries.

  That much salt is not going to be good for blood pressure.

  It would be nice to see a price/GWh of this (along with running costs, it ways they save 1 Million per GWh, how much wre 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.

    Finally something the EU can invest in with those 600 billion. Or buy it, like all EU startups were by FAANG companies. 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.
