I recall reading a couple of years ago (in New Scientist, I think) of an neat idea to turn offshore wind power (and perhaps solar) into something more applicable to variable load supply. The idea was that when not feeding the grid, the turbine would drive the electrolysis of seawater, generating hydrogen and pumping that onshore. The hydrogen batteries would then be used for variable-load supply, decoupling the supply of wind power from the demand.
