Not the person you're replying to but pumped hydro is the most primitive I know of.
Also: why must the highly variable renewables share the grid with highly variable demand, use them to make hydrogen (only when the sun is shining/wind is blowing), feed that into a totally separate power plant, simple to manage - if renewables really get cheap who cares if it's inefficient.

Tanked anhydrous ammonia will be common, with more ordered from tropical solar farms when local tankage runs low. Underground and underwater compressed air will also be common. Liquified air might be.
