AFV for Florida is a statewide organization founded to support a growing market for vehicles powered by alternative fuels, including natural gas.
Participants include trade associations, companies, and governmental entities that use of compressed or liquified natural gas as a transportation fuel. Such coalition participants may market, distribute or produce natural gas. They may also be end users of natural gas vehicles such as beer distributors, recyclers, or package delivery companies. Or, they may may service or manufacture natural gas vehicles.
Natural gas produces lower levels of greenhouse gas emissions than hydrocarbon fuels such as coal and oil. This fuel source is versatile, relatively inexpensive, efficient, and widely available in great supply.
The primary natural gas vehicle fuels are compressed natural gas (CNG) and liquefied natural gas (LNG), purchased as units called gasoline or diesel gallon equivalents (GGEs or DGEs). This measurement quantifies their energy content as compared to a gallon of gasoline or diesel fuel.
Compressed Natural Gas
According to the U.S. Department of Energy “CNG is produced by compressing natural gas to less than 1% of its volume at standard atmospheric pressure. To provide adequate driving range, CNG is stored onboard a vehicle in a compressed gaseous state at a pressure of up to 3,600 pounds per square inch.” ( U.S. Department of Energy, Alternative Fuels Data Center). CNG is used in both light duty vehicles such a cars and vans and large tractor trucks.
Liquefied Natural Gas
LNG, natural gas in liquified form, is manufactured through a purification and super-cooling process. As it is cooled below its boiling point, extraneous compounds are removed methane with small amounts of other hydrocarbons is all that remains. It is typically used in vehicles requiring longer range trips.
