A system includes a cooler configured to cool a first gas portion of a compressed gas fuel and discharge a cooled fluid. The cooled fluid comprises a cooled gas portion and a cooled liquid portion. The system also includes a separator configured to separate the cooled fluid into the cooled gas portion and the cooled liquid portion and a mixing tank configured to mix a second gas portion of the compressed gas fuel with the cooled gas portion in direct contact with one another to produce a superheated gas fuel. The superheated gas fuel comprises a degree of superheat above a lower threshold for a combustion system.
