But I do think there should be home energy storage that doesn't involve chemical batteries. Where are all the pumped hydro, flywheels, and compressed air storage for consumer use?
There’s no perfectly safe energy storage. The danger comes from the concentration of energy. Water can cause flooding or you can drown in it. Flywheels can disintegrate into shrapnel. It’s always risk management.
