Which battery technology are you referring to?

Lithium-ion has pretty big operational safety concerns (thermal runaway) and as far as I know we haven’t completely figured out the recycling either.

Pumped storage has massive environmental implications and is typically very difficult to get approved by local governments.

Flow batteries are still a very infant technology. There’s very big design differences between manufacturers that have very big tradeoffs. But I do believe these will “win” the storage race, eventually.

Flywheel and gravity storage don’t have the magnitude and duration requirements for grid-level storage solutions.
