This buffer CNG station was designed to serve a fleet of 50 to 60 transit buses. Marathon worked with the Client from the outset of the project, providing a detailed fueling needs study to determine the impact of a large expansion of the fleet. Marathon then evaluated fueling options for the Owner and continued to support the project through the design, bidding, construction and commissioning phases.

Buffer fast fill stations are designed to provide high speed fueling during extended fueling shifts that might last for several hours. The storage buffer itself is intended only to allow the compressors to continue to run loaded as buses are connected and disconnected. Buffer fast fill stations tend to include the largest and most complex equipment of all fill station configurations but provide the ability to dispense a large amount of fuel over an extended total fill shift.
