It seems clear that na-ion batteries will replace large scale grid storage especially in cold climates. This isn't another hyped up battery.

IMO, for large scale, nothing beats pumped water storage if you have the right conditions for the required lake. No risk of a bad cell causing a fire, no chemical degradation, no cooling or heating required and zero to full power within seconds just like a battery.

One of the few pumped hydro facilities in the US had a catastrophic flood

I should have been more clear. I'm saying sodium ion will be chosen when litium ion otherwise would have. We have a large battery at Moss Landing CA where I live. When those batteries need replacing, I'd bet they'll use sodium ion.

Sure. But batteries are needed for "more" and "location".

If a sodium battery is heavy and bigger but used for gridscale then that'll work fine.

For the record, there seem to be about 43 such installations and they make up 93% of commercial energy storage

Yes, but you don't. Those conditions are really scarce. And in the UK they're all either nature reserves or already used for this purpose.
