I was initially sceptical about this concept, but it seems to have merit?

Seems a lot easier than liquid air storage.

It's one of the storage methods that I think has great potential ..... so long as it works economically. I also love the irony of using CO2 as a way to help the planet.

I think this sits in the longer term storage bracket with flow batts and LAES, but before CAES and H2. So many options arriving, or developing all the time, and anything that reduces demand on conventional batteries, will help to spread the load too.

Maybe cover the domes with cheap flexible PV, perhaps Perovskite as (if) it develops well.
