1. A system for producing vehicle fuel, comprising:
- a liquefied natural gas (LNG) production facility configured to receive a natural gas from a natural gas source and to convert the natural gas to an LNG;
a compressed natural gas (CNG) production facility configured to receive a natural gas from the natural gas source and to compress the natural gas to form CNG; and
a power generation facility configured to receive at least one of a flash gas and a boil-off gas from the LNG production facility and to generate electric power.

Abstract
Systems and methods for increasing the efficiency of liquefied natural gas (LNG) production, as well as facilitating coproduction of electric power, and compressed natural gas (CNG) are described. The systems and methods facilitate producing an intermediate LNG at a higher temperature, recovering refrigeration from flash gas and boil-off gas from the LNG, using flash-gas and boil-off gas as fuel to generate electric power, and providing LNG, CNG, and electric power to a vehicle fueling facility.

11. A method for producing vehicle fuel, comprising:
-
delivering a natural gas to a liquid natural gas (LNG) production facility, and condensing at least a portion of the natural gas to form an LNG for fueling a vehicle; delivering a vapor comprising at least one of a flash gas and a boil-off gas formed from the LNG to a power generation facility, wherein at least a portion of the at least one flash gas and boil-off gas are used as fuel to generate electric power for fueling a vehicle; and delivering a natural gas to a compressed natural gas (CNG) production facility that compresses at least a portion of the natural gas to form a CNG for fueling a vehicle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
