Storing energy from turbine without batteries

Does anyone here have any info about storing energy such as Wind Energy from a turbine in another form than batteries?

I've read about developments with compressed air but I've no idea how this would work on a small scale.

A friend of mine tells me that it might be more efficient to store energy as heat or at least to convert windpower directly to heat eg. drive a generator hooked up to an electric element.

I can't vouch for this though.

This website gives details of quite a few alternatives:

I was tempted by the idea of pumping water up to a reservoir, myself, as we have steep land with a stream at the bottom, but then I did the calculations and found we'd be able to store about two thirds of a kilowatt hour!

I'd only use thermal storage if you wanted the electricity for heat anyway. If what you actually want is electricity, then you'd lose a lot of energy turning electricity into heat and back into electricity again.

I came to the conclusion that, for all their faults, batteries probably are the best.

Take nobody's word for it, especially not mine! If I offer you an ID of something based on a photo, please treat it as a guess, and a starting point for further investigations.
