There was a plan, to use giant cylinders of landscape as hydraulic batteries. The problem was the cost of excavation or building the cylinder. Then this came along, not even promoted as the future.. https://www.newcivilengineer.com/the-future-of/future-of-tun... And it's ideal.as in they could turn testsites into batteries.
