ABSTRACT:
A dual service system and method for selectively compressing and dispensing methane, hydrogen, and variable mixtures of methane and hydrogen for use as a gaseous fuel. The use of an in-line gas density meter, hydraulic intensifier, pressurized gas cooler, optional intermediate storage and multiple dispensers are disclosed. An inline gas density meter is used in combination with a programmable logic controller and a control valve on the hydrogen supply line to create a closed feedback loop for selectively controlling the hydrogen content of the resultant pressurized fuel gas.
