Fast-Fill CNG Fueling Stations
Fast-fill CNG stations are generally best suited for retail environments where light-duty vehicles, such as vans, pickups, and sedans, arrive randomly and need to fill up quickly. These stations receive fuel from a local utility line at a low pressure and then use a compressor to increase the gas to a high pressure. Once compressed the CNG moves to storage vessels so the fuel is ready to dispense so drivers experience similar fill times to gasoline fueling stations—less than 5 minutes for a 20 gallon equivalent tank.
Benefits of a Fast-Fill CNG Fueling Station
- CNG is metered and dispensed similar to ordinary liquid fuel dispensers.
- Fast filling requires about the same time as fueling with conventional fuel.
- Fast-fill CNG systems can incorporate a credit card reader for authorizing, dispensing, and billing the transaction.
- Public-access CNG stations can be unmanned and open to the public 24/7.
- Multiple customers can fuel their vehicles simultaneously.
- Requires less space for construction and dispensing.
- Can be used in conjunction with a time-fill CNG system or added to an existing time-fill CNG system at a later date.
