Non-conventional energy storage

[dr dodge]

I have been doing some reading on super critical fluids. They are pretty amazing things. I can't help but wonder if there is a way to use the it for energy storage. Quite a few listed on wiki are critical at close to ambient temps. and the pressures are very easily attainable.

How much of the energy put into making the media be recoverable days or months later?
anyone know of a more complete listing of compounds?

I don't see how the concept of energy storage applies here. Could you expalin what you have in mind?

Typically, fluid based energy storage is done by heating or cooling a fluid in an insulated container or better yet, making it change phase (such as by making ice).
