This seems kind of inefficient, but I love all these large-scale energy storage attempts. And these people are a hell of a lot smarter than I am.

Inefficient compared to batteries? I found another article saying this company hopes that the energy dome will cost ⅔ the cost of a lithium-ion battery installation with the same energy capacity. https://www.popularmechanics.com/science/energy/a61572150/carbon-dioxide-energy-dome-plant/

Every approach is inefficient. Gotta pick your losses. You have to keep in mind scalability (how many parts can be bought at what volume at what price). In particular if you are not planning many years ahead.
