ABSTRACT:
A system for delivering natural gas, from a moveable transport or pipeline, is off-loaded at an automotive re-fueling station, or other end-user facility, into one or more storage vessels equipped with internal flexible bladders. The pressure of the gas, stored inside the bladders, will be increased to levels sufficient for re-filling automotive on-board storage tanks, or other end uses, by pumping a hydraulic fluid in the annulus between the bladder and the walls of the steel storage vessels, thereby collapsing the flexible bladder and squeezing gas out to an on-board storage tank. The use of a hydraulic pump, instead of a more-expensive compressor, to pressurize the gas, results in significant cost savings which reduces the overall cost of CNG at the station, making CNG (the "preferred alternative fuel") less expensive than gasoline and/or diesel, which will enable CNG to replace gasoline and/or diesel as the primary fuel for automobiles, trucks, and busses.
