Abstract: A compressed natural gas storage and dispensing system having bulk storage tanks in fluid communication with a natural gas supply source; a compressor to produce compressed natural gas; dispensing storage tanks in fluid communication with the bulk storage tanks and in fluid communication with fuel dispensers; a liquified natural gas storage tank in fluid communication with the bulk storage tanks, wherein compressed natural gas resulting from vaporization of the liquified natural gas within the liquified natural gas storage tank is transferred to the bulk storage tanks as a supplemental source of compressed natural gas, or wherein liquified natural gas is vaporized in an ambient vaporizer and delivered to the bulk or dispensing storage tanks.

Abstract: A method of forming a polymer concrete CNG tank by forming an inflatable liner member composed of high density polymer impermeable to CNG; providing column forms as part of the liner member, the column forms having open tops and open bottoms and extending completely through the liner member; providing an outer form; positioning the liner member within the outer form with the column forms vertically oriented, the liner member being positioned to provide a gap between the liner member and the outer form; inflating the liner member; pouring polymer concrete about the liner member and through the column forms; and allowing the polymer concrete to cure. Reinforcement members may be positioned around the liner member and within the column forms prior to the step of pouring the polymer concrete.

Abstract: A fuel island redundant monitoring system having sensors of varying purpose to transmit data signals to dual remote monitoring stations. One monitoring site is a live monitoring station manned by personnel. The other monitoring station is a data receiving station utilizing unmanned machines, e.g., computers. The unmanned data station is capable of transmitting information to the manned monitoring station, to local fuel island managers and/or to local emergency responders, and/or to control equipment at the fuel island. The manned monitoring station is capable of transmitting commands or inquiries to the unmanned data station and/or to control equipment at the fuel island, and/or to local fuel island managers and/or to local emergency responders. Sensors may be dedicated to either the unmanned data station or the manned live monitoring station, or may send data to both stations.

Abstract: A compressed natural gas storage and dispensing system having descending pressure bulk storage banks in fluid communication with a supply source for CNG and dispensing storage banks in fluid communication with the descending pressure bulk storage bank, both banks being in fluid communication with fuel dispensers, wherein the delivery pressure of the CNG during, simultaneous refueling of CNG powered vehicles is equalized.
