The difficult part is storing it on the kind of massive scale required full stop. Sacrificing efficiency can only do so much to help solve this, especially since the wasted energy has to go somewhere and dealing with that has its own costs...

A lot of these problems solve themselves with proper pricing. For example if power is nearly free during daylight hours and expensive in the evening, businesses will shift some percentage of energy intensive operations to daylight hours. EV charging stations will charge more during evening hours.

Charging EVs during daylight hours while they are parked at work places instead of overnight at employees homes is another way we can shift use. Some of these things might be done via pricing, others perhaps government incentives.
