For over 100 years natural gas has been delivered through tens of thousands of miles of interstate, intrastate and distribution pipelines providing heat, hot water and fuel to residential, commercial and industrial customers across the U.S.
Below is an overview of the various states natural gas can be found. No matter the form, natural gas is a safe, clean and reliable fuel used by more than 70 million U.S. homes and businesses.
- Natural Gas (NG)
- Vapor composed of four hydrogen atoms and one carbon atom (CH4 or methane)
- Odorless, colorless and produces very low environmental emissions compared to other fossil fuels
- Compressed Natural Gas (CNG)
- Natural gas vapor compressed to less than 1 percent of its original volume
- High pressure - dispensed starting at 3,600 PSI
- Used in lower fuel consumption applications (e.g., trucks needing less than 50 gallons per day or small scale commercial and industrial users)
- Liquefied Natural Gas (LNG)
- Natural gas cooled to -260°F converts from a vapor to a liquid
- Low pressure - dispensed at less than 100 PSI
- Used in high fuel consumption applications
- 1 cubic foot of LNG is equal to 600 cubic feet of natural gas vapor
