System, method and apparatus for pressurizing a fluid to power a load

1. A system to pressurize a fluid to power a load, comprising:

a load, the load being a pump for pumping liquids, and the pump having a liquid inlet and a liquid outlet;

a high pressure gas reservoir supplying high pressure gas to the load;

a low pressure gas reservoir receiving low pressure gas discharged from the load to supplement the low pressure gas in the low pressure gas reservoir;

a gas charging subsystem supplying the low pressure gas to the low pressure gas reservoir, the gas charging subsystem comprising a plurality of series-connected pressurizing units operable to initially pressurize a gas to a low pressure, the gas charging subsystem deactivating when the low pressure gas reservoir is at a predetermined pressure threshold; and

an operating pressurization system drawing the low pressure gas from the low pressure gas reservoir and supplying the high pressure gas to the high pressure gas reservoir, and the operating pressurization system comprising a plurality of parallel-connected pressurizing units;

wherein the high pressure reservoir is nested within the low pressure reservoir, and the low pressure reservoir protects walls of the high pressure reservoir against the ambient pressure.

2. The system of claim 1 , wherein the pump includes:

a. a tank;

b. opposing first and second piston heads slidably housed within the tank, and

c. a bulkhead transversely bisecting the tank between the first and second piston heads;

d. wherein the first piston head sealingly divides the tank into a first air compartment and a water compartment;

e. wherein the second piston head sealingly divides the tank into a second air compartment and the water compartment; and

f. wherein the bulkhead sealingly divides the water compartment into a first water compartment and a second water compartment.

3. The system of claim 1 , wherein each pressurizing unit includes a cylinder with a piston rod slidably extending therefrom and a float attached to the piston rod.

4. The system of claim 1 , wherein a sequestration module is connected to the gas charging subsystem, the sequestration module sequestering a component of the the low pressure gas and supplying to the low pressure reservoir the low pressure gas without the component.

5. The system of claim 4 , where the gas is air and the component is carbon dioxide.

6. The system of claim 5 , wherein the air enters the gas charging subsystem at atmospheric pressure through an atmospheric intake.

7. The system of claim 1 , wherein the gas charging subsystem is configured to distribute surplus low pressure fluid when the low pressure reservoir is within a predetermined threshold of its capacity for storing the low pressure fluid.

8. The system of claim 7 , wherein a manifold is connected to the gas charging subsystem to distribute the surplus low pressure fluid.

9. The system of claim 8 , further including a second operating pressurization system connected to the manifold to receive the surplus low pressure fluid.
