Abstract: The present application pertains to processes and systems for storing or generating power. A representative method stores energy by pumping a first fluid having a first density from a first reservoir at a first elevation to a second reservoir at a second elevation using a first fluid pump and pumping a second fluid having a second density from the second reservoir to the first reservoir using a second fluid pump. Power is generated by allowing the second fluid to transfer from the first reservoir to the second reservoir using a second fluid turbine and allowing the first fluid to transfer from the second reservoir to the first reservoir using a first fluid turbine. Generally, the first elevation is above the second elevation; the first fluid density is less than the second fluid density; the first fluid displaces the second fluid in the second reservoir during the storing of energy; and the second fluid displaces the first fluid in the second reservoir during the generating of power.
