NOVELTY - The method involves pressurizing fluid initially in a series of stages to yield low pressure fluid. The low pressure fluid is again pressurized concurrently in parallel stages to yield high pressure fluid to be supplied to loads (118). The high pressure fluid and the low pressure fluid are accumulated separately. The accumulated high pressure fluid is supplied to the loads. Low pressure fluid received from the loads is combined with the accumulated low pressure fluid. The combined accumulated low pressure fluid is re-pressurized concurrently in parallel stages to yield the high pressure fluid.    USE - Method for pressurizing fluid to power loads to generate energy. Uses include but are not limited to a reservoir, generator, extractor e.g. desalinator and carbon-di-oxide sequestrator, and an injector i.e. hypoxia-reducing air injector.    ADVANTAGE - The method enables deploying few pressurizing unit and deploying fewer conduit between load-units for effective resisting of interior and exterior pressure in an economical manner with improved maintenance. The method allows compressing atmospheric air by multiple stage of pressurization unit and harness maximum incident energy, so that the loads are powered effectively. The method allows the low pressure reservoir to be connected with an atmospheric intake for initial charging operations, thus avoiding replenishment of air due to leakage or drawn-off to power ancillary equipment. The method enables preventing production of tremendous heat sink than can freeze proximate apparatus.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a system for pressurizing fluid to power loads    (2) an apparatus for pressurizing fluid to power loads    (3) an apparatus for storing and conveying pressurized fluid.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a system for pressurizing fluid to power loads, where a pressurization unit has a standard cylinder suspended from a tailored float and a sequestration stage is defined between a charging subsystem and an operating subsystem.
