Studies have been published which address fast filling of Natural Gas Vehicle (NGV) fuel containers. Diggins states that NGV fuel containers cannot be fully filled during a fast fill, and that all-composite fuel containers cannot be filled as full as other types of fuel containers.
There are issues in this prior work which may have a significant effect on the author’s conclusions. Fast fill testing conducted by Powertech Labs shows the Lincoln Composites’ fuel container has significantly better fill performance than projected by Diggins. Testing of a dispenser control system by Kountz and Blazek demonstrates all types of fuel containers can be properly filled with proper dispenser control algorithms and performance.
