Well concrete and steel are the major material components, fairly cheap, but pumps and turbines require high precision machining, fairly expensive. Lithium will probably be cheaper.
Probably not economical in current conditions, but worth doing to say it was done.

Most storage systems have a big downside in that the J that you use once a year costs just as much to store as the one you use every day. This perhaps permits putting a lot of air down there as reserve for when the sun doesn't shine for days on end. Lithium is non-viable for dealing with long periods of darkness (big storm on top of your collectors.) To ensure the lights stay on in the worst case you need weeks worth of storage.
