CNG Stations

Bath has been designing CNG stations since the early 1990's.  The list in the table at left describe a few of our recent projects.

The first step in designing a CNG station is to identify the type of vehicles will be fueled (light-duty vehicles, forklifts, buses, solid waste, etc.). The type of vehicles often determines the best station design a specific fleet. For example, a school bus fleet can best be served by a slow-fill system, while a fast-fill system would be better for a light-duty vehicle fleet. The number of vehicles and size of their tanks must be identified so the station can be correctly sized. If vehicles will be purchased over a period of time, decisions should be made about whether to phase the installation of compressors over time or whether to build out the station in one step. The fleet manager is likely to have preferences about the fuel management system. Some require detailed records showing the quantity of fuel placed in each vehicle so it can be compared to mileage and other factors. Others are interested only in the gross amount of fuel consumed by the fleet in a period of time. Public access stations need credit card payment or tracking systems.
