CNG or compressed natural gas is a domestically available, economical, clean burning, alternative fuel source for vehicles.
Rather than burn gasoline or diesel fuel, a consumer would fuel their vehicle with natural gas. In order to provide enough range, the gas is compressed and stored on the vehicle in pressurized tanks. Tanks that can hold up to 3,600 psig.
Sounds a little scary doesn’t it? Not when you compare the physical properties of Natural Gas and gasoline. The fact is that natural gas is a much safer fuel than gasoline. Natural gas readily disperses in air because of its simple molecular structure. (Ever wonder why the stove in your home doesn’t burn gasoline instead of natural gas?) Just take a look at the chart below and those on following tabs for some interesting facts:
Natural Gas – a simple hydrocarbon
A typical configuration consists of a pre-treatment skid, the biogas cleaning module, and optional polishing modules to condition the gas for specific applications. The system’s compact footprint makes it suitable for locations with limited land available to site a project.
As you can see from the chart, natural gas has a ratio of four (4) hydrogen atoms to one (1) carbon atom. This makes CNG the lowest carbon fuel available today: with the exception of hydrogen itself, natural gas (NG) has the highest hydrogen content of any fuel.
Its simple molecule structure makes complete combustion easy and results in less tailpipe pollution than petroleum fuels. Natural Gas Vehicles (NGVs) produce approx. 93 – 95% less emissions than similar petroleum fueled vehicles. (source: EIA)
