Understanding CNG Fueling Stations


When your fleet relies on compressed natural gas, it could be a good idea to have your own CNG fueling station on hand. Many companies have opted for this method instead of relying on third-party suppliers. Having your own fueling station makes it more convenient for you to fuel your fleet, and it can also be more cost-effective in the long run.

CNG fueling stations are not one size fits all. There are different types of fueling stations that offer different benefits for fleets with different needs. If this is something you’re considering, learn more about the different CNG fueling stations to determine which makes the most sense for your fleet.

Time-Fill Stations
Time-fill stations are a great option for those looking for a cost-effective CNG solution. These stations can be custom designed to meet your fleet fueling needs, so it’s a great choice whether you have a fleet of 6 or 60. These stations require very little storage—the gas supplied by your utility provider is delivered to a compressor that slowly dispenses CNG into your vehicles over a period of time. Once the fuel tanks are full, the system automatically stops fueling.

Time-fill stations can simultaneously fuel multiple heavy-duty vehicles, so they are perfect for fleets that return to a central location each day, such as mass transit buses, school buses, concrete mixers, delivery trucks, or refuse trucks.

Fast-Fill Stations
Fast-fill stations deliver CNG as quickly as traditional liquid fuels—they can deliver up to 10-20 GGEs per minute depending on the design. Unlike time-fill stations, fast-fill stations require higher horsepower compression units and utilization of high-pressure storage that make CNG readily available, which is why these are a great option for both private fleets and retail use. The utility supplier’s gas source is delivered to a compressor at a low pressure. CNG is then stored at a high pressure in multiple storage tanks.

If you have light- or medium-duty trucks that need multiple fill-ups throughout the day, such as transit buses or taxis, fast-fill stations are a great choice.

Combination Stations
Sometimes you need the best of both worlds, and the combination station incorporates elements from both the time-fill and fast-fill stations. These stations are the right choice for truck fleets that require mid-day fill-ups as well as overnight fueling. If you need more flexibility in your fueling schedule, a combination station is the right choice.
