Yes. The most efficient means seems to be using air compressed by wind generated electricity to replace the air that would otherwise have to be compressed in a gas turbine. the compressor section of a gas turbine apparently uses roughly half the energy generated by the hot section turbine.
If you do a search on "compressed air energy storage" you will find mention of a few such systems built or building.
