Strange Article on Solar Thermal and Energy Storage

I keep an eye out for articles like this that talk about concentrated solar power (CSP –aka solar thermal) and the use of energy storage to make that power dispatchable.  Normally, they contemplate molten salt, as the cost of storing energy as heat is so much lower than other technologies, e.g., batteries. 

Here, however, the conversation, for some strange reason, revolved around compressed air energy storage (CAES).    Yes, as the spokesperson said, “the energy to compress the air could come from a solar thermal turbine. “ 

I’m not saying that it couldn’t, but it strikes me that it wouldn’t, given the horrendous inefficiencies that the project would suffer.  Let me ask frequent commenter Glenn Doty (and anyone else):  Am I wrong here?
