Here are several key terms to kinow when discussing natural gas fueling. Understanding them will help anyone sound like a pro when discussing natural gas including:
Compressed Natural Gas (CNG)
- The vehicle fuel tank is a high pressure (3,600 psi) cylinder.
- A CNG vehicle gets about the same performance as a gasoline vehicle with only a slightly lower gasoline gallon equivalent (GGE).
- CNG is used in light-, medium-, and heavy-duty vehicle applications.
Liquefied Natural Gas (LNG)
- Produced by super-cooling natural gas to negative 260-degrees Fahrenheit in order to convert it to a liquid. LNG is typically used in heavy-duty truck applications.
- Designed to run only on natural gas
- Runs on either natural gas or gasoline, with two separate fueling systems connected the same internal combustion engine.
CNG Infrastructure Types
- Drivers can fill up in the same amount of time as a gasoline vehicle.
- Best suited for retail stations, where vehicles arrive in need of a quick fill, and CNG can be dispensed alongside gasoline.
- May take many hours to fill up; the time depends on the number of vehicles fueling, compressor size, and storage.
- Typically used for fleets with central refueling locations that allow vehicles to fill up overnight.
