ABSTRACT:
A system and method for selectively refueling a plurality of vehicle storage tanks with compressed natural gas (CNG) are provided that utilize a compressor system operable at suction pressures ranging from about 330 to about 3600 psig and discharge pressures ranging from about 330 to about 4500 psig in combination with means for temporarily storing CNG at an intermediate storage pressure of from about 330 to about 4500 psig, preferably from about 1700 to about 2700 psig, means for selectively filling vehicle storage tanks with CNG from an inlet source, from the compressor discharge and from the intermediate storage tanks, and means for selectively supplying CNG to the compressor inlet at either the available line pressure or the intermediate storage pressure.
