Enhanced methods for operating refueling station tube-trailers to reduce refueling cost

An apparatus for operating a refueling station to reduce hydrogen refueling cost comprising:

• the refueling station including a gaseous fuel supply source including a plurality of tanks on a tube trailer coupled to a first control unit, and high pressure buffer storage having predefined capacity coupled to a second control unit and the first tanks on the tube trailer by a pressure control valve and the first control unit, and a compressor;
• said first control unit and said second control unit monitoring a state of the hydrogen refueling station;
• said first control unit and said second control unit operating the hydrogen refueling station at different operational modes depending on the state of the refueling station at the beginning of each operational mode;
• and
• said first control unit and said second control unit assessing the refueling system at the end of each operational mode to identify the state of the system and selecting a next mode of operation.
