In one embodiment the system pertains to a first storage reservoir near the surface of a body of water and configured to store a fluid which has a lower density than water. A second storage reservoir is located below the surface of the body of water and configured to store a fluid which has a higher density than water. A pump, generator, and the first and second reservoir are operatively connected such that power is stored by displacing the fluid which has a higher density than water in the second storage reservoir by pumping the fluid which has a lower density than water in the first storage reservoir to the second storage reservoir. Power is generated or discharged by allowing the fluid which has a lower density than water in the second storage reservoir to return to the first storage reservoir. The fluid which has a higher density than water may be in liquid form."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low density fluid displacement to store or generate power","description":"The present application pertains to systems and methods for storing and generating power.
