> "All the problems associated with" what?

Economic challenges of quickly building grid-scale battery storage , battery production for the entire globe, NIMBY's etc.

> Modern batteries don't burst into flame

they literally do

> the overwhelming bulk of storage is not batteries

Well overwhelming bulk is a high bar and storage is geography dependent. Germany f.e. can't build as much pumped storage as Australia and Australia built a large amount of battery storage vs PSH.

Germany can has and will very well be building hydrogen and compressed air storage.

Well they certainly say they will, not sure about the rest.

Germany has an overabundance of hills. Most places do. But pumped storage is just one of many options

Modern batteries do not burn. Teslas do.

> an overabundance of hills.

That's not sufficient for pumped storage at scale, but Germany is mostly focusing on hydrogen for now.

It's a problem with lithium batteries in general, not just Tesla.

Lithium-ion batteries burn. But the topic was "modern batteries", which at the instant moment means LiFeP batteries, not "previous-generation batteries".

Lithium is anyway not favored for use in utility-scale storage, where its light weight offers no compelling value. Up-and-coming chemistries include iron-air (no explosions), calcium-antimony (no explosions), and bromine-zinc (no explosions). Hundreds of other chemistries are available.
