Batteries are for diurnal leveling. You don't need 24 hour storage for diurnal leveling.

For long term or rare event storage, something like hydrogen will likely be cheaper. Efficiency is lower, but that's a good tradeoff to get lower per-kWh-capacity cost.

We're still a long way from diurnal leveling though. Currently CA's battery output can't even match a single nuclear reactor; it's currently outputting 459MW to Diablo Canyon's 1,140MW.
