Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Isn't there a design, for wind powered energy plants, that consists (basically) of a whacking huge air pressure energy reserve?  IIRC, excess power is channeled into pumps that increase the air pressure inside a tank.  The potential is then used to drive the turbines during low/no wind.

to do much good.  

I know those tiny compressed air cars have fairly small tanks, but they operate at very high pressure.  Much easier to build a small strong tank than a huge one.

People are looking at large scale battery systems, giant flywheels etc.  but the old reliable is pumping water uphill for later use.

There are, as I understand it, functioning versions of this.

There are also potentials for constructing versions of hydro facilities ...

Could use wind to make hydrogen (already occurring in limited cases) ... flywheel storage ... etc ...

Lots of potential storage options ... challenge is to move from the potential to cost-effective large-scale implementation.
