»It's happening, it just hasn't yet arrived at scale.«

Making it at scale is a MAJOR challenge.

Germany alone consumes up to 1.6 billion kWh on a single day. That's the capacity of 16 million Tesla-S batteries with 100 kWh.

Solving the storage problem is simply infeasible and is never going to happen in the foreseeable future!

Germany has 50 million cars. Are you saying that after those have been turned eletric their batteries alone would be enough to cover the countrys battery needs?
Usually people buy cars to drive them around, not to use them as batteries for poorly designed grids.
Ergo the rise of concentrated solar thermal plants (CSPS) and using excess peak solar to produce hydrogen, ammonia, methonal, etc for off peak (night time) demand.

Batteries aren't the only way in which energy can be offset by 10 hours to meet lower night time demand.
