<p>Systems and methods for storing and releasing energy comprise directing inlet air into a vertical cold flue assembly, cooling the air and removing a portion of moisture. The air is directed out of the cold flue assembly and compressed. The remaining moisture is substantially removed. The air is cooled in a main heat exchanger such that it is substantially liquefied using refrigerant loop air. The substantially liquefied air is directed to a storage apparatus. In energy release mode, working loop air warms the released liquid air such that the released liquid air is substantially vaporized, and the released liquid air cools the working loop air such that the working loop air is substantially liquefied. The substantially vaporized air is directed to a combustion chamber and combusted with a fuel stream. A portion of expanded combustion gas may be used to heat and substantially vaporize the released liquid air.</p> |
