Abstract
The present invention relates to systems and methods for pumping or removing a fluid from a region within or on top of or in contact with a water or liquid body and applications for said systems and methods. Some embodiments may be applicable to, for example, inhibiting or preventing growth formation or fouling of structures in liquid environments. Other embodiments may be applicable to, for example, an energy storage device or a tidal power energy generation system.
Claims19
A system for generating electricity comprising:
- 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 and is substantially immiscible with water;
- a second storage reservoir located below the surface of the body of water and configured to store water;
- a pump;
- and
- a generator;
- wherein the pump, generator, and the first and second reservoir are operatively connected such that electricity is stored by displacing water in the second storage reservoir by pumping low density fluid in the first storage reservoir to the second storage reservoir and electricity is generated or discharged by allowing the low density fluid in the second storage reservoir to return to the first storage reservoir;
- and
- wherein the water and the fluid which has a lower density than water are both in liquid form.
5 more elements
A process to generate energy comprising:
- storing energy by displacing at least a portion of a first fluid having a first density with a second fluid having a second density which is lower than said first density wherein said first and second fluid are substantially immiscible in each other and wherein said second fluid is stored in a second reservoir located above a first reservoir which stores said first fluid;
- allowing a power discharge by displacing at least a portion of the lower density second fluid with the first higher density fluid;
- wherein said allowing step is facilitated by pressure and gravity;
- wherein said allowing step occurs beneath a surface of water;
- and
- wherein the first fluid and the second fluid are both in liquid form.
