Water tank energy storage would be far safer. During hours of off-peak energy is used to to fill a water tank to capacity. During peak hours the water is allowed to flow to a second, lower tank through a hydroelectric generator. During off peak the water is pumped back up and the cycle repeats.

Or we could build a crap-ton of nuclear plants.

It’s called “pumped hydro” and has been around forever. The “tanks” are upper and lower reservoirs. Pump water uphill at night when power rates are low and there is unused capacity…flow the water downhill through generators the next day from noon to 8 pm.

Simple and effective “battery.” Hard to find sites.

Castaic Lake pumped storage north of Los Angeles. Three new reservoirs are proposed for the California coast to store offshore wind turbine energy.
