As an author & a recovering engineer, I have used windbottling in my post extermination novella (Coastal Event Memories, Volume V, Voyage of Discovery). In the story, a surviving community on the Eastern shore of an Inland Sea that used to be the California Central Valley construct a ship to explore the world and contact other groups of survivors. The sail propelled ship had 20 KW of salvaged solar panels, and used direct coupled motor generators to drive Tesla Turbine compressor motors. The compressed air was stored in salvaged carbon graphite fiber pressure tanks. When the solar array was not producing, the stored air was throttled back through the Tesla Turbine motors and drive the generators. The electrical power was used to provide lighting, auxiliary propulsion, and limited instrumentation.

While this concept does use some artistic license, There was a test system built in Kansas that used off peak grid power to compress air in an salt mine cavity. The stored air was then used to drive a turbine generator to support peak grid power loads.
