Compressed natural gas (CNG) is natural gas that has been compressed for use as a vehicle fuel or to heat homes and cook food. Natural gas forms from decomposing organic material and is mostly methane. It is extracted and purified, then compressed to 1% of its volume at atmospheric pressure to form CNG. CNG vehicles are becoming more popular due to CNG's reduced emissions compared to gasoline, the abundant natural gas resources in the US, and because natural gas pipelines already exist in many areas. However, CNG is flammable, displaces oxygen, and must be handled cautiously.

1. CNG, LPG, LNG Etc…
(PRESSURIZED GAS AND LIQUID)

2. Pressurized Gas can be DEADLY!
…….Proceed with CAUTION!

3. What is CNG?
Compressed Natural Gas of course!
What is Natural Gas?
Good Question!
•Extremely flammable
•Displaces oxygen
•Lighter than air
•Stored at high pressures
(Compressed)

4. Natural Gas
Natural Gas (Mostly Methane) is formed by the anaerobic
decomposition of organic material.

5. CNG
So CNG is compressed natural gas, compressed to 1% of its size at
atmosphere pressure.
Where do we get it?

6. CNG
After the natural gas is collected it is purified, filtered, and mercaptan
is added for leak detection, since natural gas is colorless, tasteless,
and odorless.

7. CNG
Most people know natural gas is used to heat your home, and cook
your food, but did you know it can power your vehicle?

8. Why would we do that?
There are several reasons why CNG
vehicles (NGV) are popular. Some
are;
1. Reduced Emissions
2. Abundant resource in United
States
3. Infrastructure is “almost” there
(pipelines everywhere)
