There is better energy storage method than batteries availabe in some parts of the U.S..
We have it a few miles from here. It's a reservoir that they pump water into during low energy usage times and then drain it through turbines to generate electricity during high usage times.
It seems like a great energy storage approach to me, but there must be problems with it because it's not used many places. Maybe the main problem is due to lithium battery storage being the "hot thing" right now.

Thats an economics issue. During peak use periods they produce power by allowing water out, but pumping it back always uses more energy than it creates, But, since power is worth more during peak use times the difference in cost to pump it back can be overcome at night when consumption, and price per Kw are lower.
