Pneumatic energy storage and pumped water storage both have very low efficiency but also low cost, so there are plenty of techs in this space that are being explored.
The question is whether wind and solar can be made cheap-enough to be worth overbuilding them five times over to feed into inefficient energy storage, or if we should just stick to batteries or hydrogen.
