If I want to store 10-20 kilowatts or more excess energy, what would be the best way of doing so?

Easiest one would be a huge-ass plumbum-sulphuric acid battery like in a car but the size of a small room. A bit unconventional, but costs a thousand bucks instead of 20.000 when you buy LiFePo-shit for something like solar panels.

What else? Is pumping water up somewhere worth the effort?
