About Compressed Natural Gas


 CNG is a readily available alternative 

to gasoline that’s made by compressing natural gas to less than 1% of its volume

at standard atmospheric pressure. Consisting mostly of methane, CNG is odorless, colorless and tasteless. It's drawn from domestically drilled natural gas wells or in conjunction with crude oil production. CNG costs about 50% less than gasoline or diesel and emits about 90% fewer emissions than gasoline and is in abundance in America.

 FAQ    

 What is natural gas?


Natural gas primarily consists of methane (around 90%), with small amounts of ethane, propane and other gases. Methane is a simple gas molecule made up of one

atom of carbon and four of hydrogen (CH4). 

It is lighter than air and burns almost completely, with by-products of combustion being carbon dioxide (CO2) and water (H2O).


 

 What is CNG and where does it come from?


CNG is natural gas that is compressed to less than 1% of its volume at standard atmospheric pressure. It originates where natural gas does - from drilled natural gas wells as well as in conjunction with crude oil production.

 Why use natural gas as a fuel?


Engine, urban, and greenhouse gas emissions are much lower than from gasoline or diesel engines. It decreases our reliance on foreign fuel sources (98% of the natural gas used in the US is from North America), and it costs less per energy unit than gasoline or diesel.


 

 Who provides the CNG?


The local utility provides the CNG, which is piped

to the location where the gas will be compressed before being dispensed into the vehicles. 

 How is CNG Fuel measured?


CNG Fuel is measured in GGEs. In 1994, the US National Institute of Standards and Technology (NIST) defined a gasoline gallon equivalent as 5.66 pounds of natural gas. GGE is a factor that describes the number 

of gallons of a fuel that has the equivalent amount of energy as 1 gallon of gasoline.


 

What is GGE?


A gasoline gallon equivalent (GGE) is the amount

of alternative fuel it takes to equal the energy content of one gallon of gasoline. One GGE of natural gas produces an equal amount of energy

as one gallon of gasoline. 

 

How do you use natural gas as a transportation fuel?


Vehicles use natural gas as a fuel by either compressing it or liquefying it. Compressed natural gas (CNG) is the most common form of natural gas used in vehicles, by being compressed to 3600 psi. Engines for heavy-duty vehicles use liquefied natural gas (LNG), which is stored on the vehicles at –260º F.

CNG is not as new as you might think...


Natural gas has been considered for use

as a transportation fuel since the 1930’s. However, it was put on the back burner when large crude oil fields were discovered in the US and Middle East. Natural gas emerged again during the fuel shortage of the 1960’s and 1970’s and has slowly developed since then into a viable alternative to gasoline.
