Abstract: An apparatus for supplying fuel to a gaseous fuel consuming device, such as a gaseous fueled vehicle or the like, generally includes one or more gas compressors for compressing the gaseous fuel to a predetermined pressure, preferably less than 500 psig (3450 kPa). The apparatus preferably also includes apparatus for cooling the compressed gaseous fuel at least to ambient temperatures. Sorbent filtering and storage means are also preferably provided for maximizing the amount of fuel to be stored in the apparatus in order to supply a quick initial charge of the gaseous fuel to the vehicle or other gaseous fuel consuming device.

Abstract: A low pressure gaseous hydrocarbon fuel storage system and power plant is described, which generally comprises means for storing a self-contained supply of a gaseous hydrocarbon fuel, a prime mover, means for conveying the gaseous hydrocarbon fuel to and from the storing means, and means for controlling the flow of the gaseous hydrocarbon fuel from the storing means to the prime mover. The storing means, which may include one or more vessels or cylinders, contains a predetermined sorbent material for reducing the pressure at which a given amount of the gaseous hydrocarbon fuel is stored. The prime mover, such as an internal combustion engine, has means for combining the gaseous hydrocarbon fuel with air to produce the mechanical energy therefrom necessary to move the vehicle.

Abstract: A low pressure gaseous hydrocarbon fuel storage system and power plant is described which generally comprises on-board means for storing a self-contained supply of a gaseous hydrocarbon fuel, a prime mover, means for conveying the gaseous hydrocarbon fuel to and from the storing means, and means for controlling the flow of the gaseous hydrocarbon fuel from the storing means to the prime mover. The on-board storing means, which may include one or more vessels or cylinders, contains a predetermined sorbent material for reducing the pressure at which the gaseous hydrocarbon fuel is stored. The conveying means is adapted to convey the gaseous hydrocarbon fuel to the on-board storing means from a stationary source of the gaseous hydrocarbon fuel, and also to convey the gaseous hydrocarbon fuel from the storing means to the combining means of the prime mover during the operation of the vehicle.
