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.
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.
