At least with fixed position industrial batteries, folks can control heat and discharge/recharge rates etc., so they should last longer than in cars.
I can't see batteries being much of a factor on the grid in the US for a long time, if ever. I wonder if we could use excess power to generate hydrogen and then store than and run fuel cells as needed, but it sounds expensive, to me. The hydro storage angle looks more probable, though then you need dams.
Vital to grid reliability, today, the U.S. pumped storage hydropower fleet includes about 22 gigawatts of electricity-generating capacity and 550 gigawatt-hours of energy storage with facilities in every region of the country.
