The main issue with using batteries for load balancing is the massive resource investment required for them at a grid level, BUT that’s more of a concern with lithium based batteries due to a number of factors. Sodium batteries use way more easily accessible and abundant materials.

NGL I’m hella fuckin hyped about sodium batteries vs lithium batteries.

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.
