> neither practical nor safe to build 100% solar grid
No one is suggesting a 100% solar grid. You combine solar, wind, geothermal, hydro, and nuclear.
> battery
Battery prices have been in free-fall for a while, and there are a bunch of interesting tech for grid-scale energy storage. The vanadium redox battery is appealing for grid-scale energy because the energy capacity is determined by the amount of liquid you store in its tanks, so scaling that is trivial. Sodium ion batteries are appealing since they're made with abundant materials and their lower energy density compared to lithium ion isn't a concern for grid-scale storage.

Which is why no one is suggesting 100% solar. You do a mix like I described earlier.
