Compressed Natural Gas (CNG)

Definition - What does Compressed Natural Gas (CNG) mean?

Compressed Natural Gas is natural gas stored at a high pressure which can be used as an alternate for gasoline, propane or diesel fuel. It is safer than other fuels as natural gas is lighter than air and it disperses immediately when released. It can be found above oil deposits or can be collected from landfills or plants of wastewater treatment where it is known as biogas. It is formed by compressing the natural gas to less than 1 percent of its volume occupied at the standard atmospheric pressure.

Petropedia explains Compressed Natural Gas (CNG)

When Compressed Natural Gas is released it mixes with air and becomes flammable but only if the blend is within 5-15 percent natural gas. However, if the blend is less than 5 percent natural gas it does not burn as there is no enough oxygen. It is produced both domestically and worldwide at comparatively low cost and it is cleaner than diesel fuel or gasoline. The placement and cost of fuel storage tanks is the biggest barricade to quicker and wider adoption of the Compressed Natural Gas as a fuel.
