A fuel storage container for use in fuel storage and distribution arrangements to store pressurized natural gas (LNG) at a pressure of approximately 1035 kPa (150 psia) at approximately 75 90 kPa (1100 psia) and at a temperature of approximately -123 ° C (-190 ° F) to approximately -62 ° C (-80 * F) and supply vaporized LNG upon demand for combustion in an engine. Fuel storage containers are constructed of ultra-resistant low-alloy steel containing less than 9% by weight nickel, strength and fracture toughness suitable for containing such liquefied pressurized natural gas. Fuel storage distribution arrangements use fuel storage containers. While not limited to this, the present invention is especially useful for automobiles, buses, trucks, and other vehicles with engines designed to operate by natural gas combustion. |
