A method and system(s) are disclosed for integrating a new fuel into an operating transportation system in a continuous, seamless manner, such as diesel fuel being gradually replaced by compressed natural gas (“CNG”) in long haul trucks. Integration can be implemented using two enabling technologies. The first is an engine system capable of operating seamlessly on two or more fuels without regard to the ignition characteristics of the fuels. The second is a communications and computing system for implementing a fueling strategy that optimizes fuel consumption, guides the selection of fuel based upon location, cost and emissions and allows the transition from one fuel to another to appear substantially seamless to the truck driver.

1. A system for fueling a vehicle, comprising: a billing module operable to determine a cost of fuel dispensed to each of a plurality of fueled vehicles;one or more fuel-containing vessels;one or more compressors;a plurality of fueling posts;one or more manifolds;one or more flow meters; andone or m
1. A system for fueling a vehicle, comprising: a billing module operable to determine a cost of fuel dispensed to each of a plurality of fueled vehicles;one or more fuel-containing vessels;one or more compressors;a plurality of fueling posts;one or more manifolds;one or more flow meters; andone or more transmission pipelines in fluid communication with the one or more fuel-containing vessels, the plurality of fueling posts, the one or more manifolds, the one or more flow meters, and the one or more compressors;wherein: in response to a request for fuel, the fuel is dispensed to a vehicle of the plurality of vehicles from a selected one of the plurality of fueling posts;an amount of fuel dispensed at any of the plurality of fueling posts is determined by the one or more flow meters, the one or more flow meters being operatively connected to the billing module;each of the plurality of fueling posts is located in or adjacent to a vehicle parking space that is free of a ground catchment system for spilled fuel;if the fuel is a gaseous fuel, the billing module determines the cost of the gaseous fuel dispensed differently based on whether the gaseous fuel is dispensed in a slow-fill mode or a rapid-fill mode;the slow-fill mode is a mode in which the gaseous fuel is pressurized, over a slow-fill period, from a lower pressure to a maximum pressure of a receiving fuel receptacle of the vehicle; andthe rapid-fill mode is a mode in which the gaseous fuel is expanded, over a rapid-fill period, from a higher pressure source to the maximum pressure of the receiving fuel receptacle. 2. The system of claim 1, wherein the gaseous fuel is one of natural gas, hydrogen, hydrogen enhanced natural gas and propane. 3. The system of claim 1, wherein the billing module determines the cost for the rapid-fill mode to be more than the cost of the slow-fill mode. 4. A method for fueling a vehicle, comprising: at a selected fueling post, dispensing a fuel to a parked vehicle, wherein the fuel is dispensed from a fueling system, the fueling system comprising one or more fuel-containing vessels, one or more transmission pipelines, one or more compressors, and one or more manifolds, operatively connected to the selected fueling post;measuring, by one or more flow meters, an amount of fuel dispensed to the parked vehicle; anddetermining, based on the amount of dispensed fuel, a cost to be paid by an operator of the parked vehicle,wherein an area around a location of fueling of the parked vehicle is free of a catchment system for spilled fuel,wherein if the fuel is a gaseous fuel, the determining determines the cost of the gaseous fuel dispensed differently based on whether the gaseous fuel is dispensed in a slow-fill mode or a rapid-fill mode,wherein the slow-fill mode is a mode in which the gaseous fuel is pressurized, over a slow-fill period, from a lower pressure to a maximum pressure of a receiving fuel receptacle of the parked vehicle, andwherein the rapid-fill mode is a mode in which the gaseous fuel is expanded, over a rapid-fill period, from a higher pressure source to the maximum pressure of the receiving fuel receptacle. 5. The method of claim 4, wherein the gaseous fuel is one of natural gas, hydrogen, hydrogen enhanced natural gas and propane. 6. The method of claim 4, wherein the determining determines the cost for the rapid-fill mode to be more than the cost of the slow-fill mode.
