Electric companies currently do not need storage. They need the power the most when the sun is out.

That could be, or it could be a combo of homes, businesses and cars. Tech companies though are still going to need local solutions. The power requirements of data centers and cloud computing are enormous.Long-term, won't the storage come from 100 million electric cars, plugged into the grid on any given evening? Smart management of a national-scale fleet of electric cars creates quite a bit of storage capacity.

Probably not. Having a smart charger that puts charge in when the utility is 'flush', e.g. with renewable power, yes. Pulling energy out of the battery to power the grid, probably not much.
The first, demand response helps with RE intermittency.
The second, will wear the battery out prematurely. For example, my LEAF battery costs $6000 has a 24 kWh capacity and is good for say 1000 cycles. Thus, each 24 kWh cycle costs $6 in wear, or $0.25/kWh. While batteries will get cheaper, they will likely be undercut by stationary batteries.
If the power company would pay you to add miles on your vehicle, and the miles actually wore it out like real miles, how much would you charge per mile?
