Energy storage by compression:
I'm assuming you're speaking of compressing air, or some other gas to store energy. The issue is how you "compress" it. There's isothermal compression, adiabatic, and isobaric. No process will exactly fit any of these, but some have greater entropy increase than others. Whichever process produces the smallest change in entropy will result in the greatest fraction of energy stored. I don't remember exactly which it would be, but I am assuming adiabatic, as the greatest work on the gas would be done in that case, and so this should mean the greatest increase in the internal energy of the system for a particular amount of energy put in. This is just my two cents. [[User:Colin|Colin]] 22:28, 24 May 2011 (PDT)
