A time-fill system does not have a storage system and has a much smaller –and less expensive– compressor. It typically refuels CNG vehicles overnight at a rate of about one gallon per hour. Time fill works for vehicles that remain idle overnight, such as refuse trucks and school buses
There are also home refueling options for individuals that own a CNG powered vehicle and are looking for the convenience of being able to fuel at home. The units connect to a residential gas line and typically hung on a garage wall. They can fuels a single vehicle at the rate of slightly less than a half a gallon per hour.
Natural gas may also be stored on-board in the form of liquefied natural gas or LNG. To become LNG, natural gas must be cooled to –260 degrees Fahrenheit. The biggest advantage of LNG over CNG is space requirements. LNG requires only 30 percent of the space of CNG to store the same amount of energy. In order to keep the LNG cold, LNG is stored on-board vehicles in thermal storage tanks.

- NGV Texas converted several of our 42 school buses to run on CNG. They provided the best quality conversion for the amount of money spent. We had no issues with those conversions and were pleased to be the first heavy duty vehicles to use their patented Fuel Interface Module. I wish all of our new buses were as reliable as these NGV Texas conversions.Charles Stone
