Here's an interesting bit I just ran across. I've heard about compressed air storage but have never seen a project take advantage of it (apparently there are only two in operation). Iowa to Combine Wind Energy & CAES Technology I didn't see any numbers on cost/kWh but the article did say that the cost of the storage infrastructure would run about $200,000-225,000, which is well less than the cost of a single utility scale turbine.
