The only current storage technology cheap enough if you happen to have the nice problem of having to curtail renewable production during peak is water electrolysis -- if you also happen to have the natgas storage and distribution infrastructure already in place.
MWh and GWh scale battery infrastructure isn't cheap at all. It will likely take a decade to have affordable 10 kWh scale domestic storage, and it will be most likely sodium, not lithium. 100 kWh scale, which is almost enough for seasonal demand levelling will still take pressurized hydrogen in cylinders.
