Huge hurdles to overcome. We'll get there eventually.
The Tesla grid storage batteries will pay for themselves very quickly.

And that doesn't even count the fact that we no longer would have to build peaker plants - which are VERY EXPENSIVE to build and to operate.

Gravity storage systems are cheap, scalable, and very efficient - about 85%.
