Natural gas is a clean, low cost, domestically available alternative fuel that can power our vehicles. The advantages to our energy independence by reducing foreign oil imports, the reduced cost compared to gasoline and less emissions have been well documented. However, there may still be a misconception about the safety of Compressed Natural Gas (CNG) compared to gasoline.
All fuel sources contain energy that is released through combustion and any fuel can be potentially dangerous if not properly handled. Throughout time we have learned to harness these fuels for heating, light and powering our vehicles.
The fact is that CNG is safer than gasoline as a vehicular fuel based upon two important facts; the physical qualities of natural gas and the structural integrity of the NGV fueling system.
Natural gas or methane is a non toxic gas that is lighter than air. This means that it will not puddle (like gasoline) or sink to the ground like propane, which is heavier than air. Instead, Natural Gas will rise and dissipate in the atmosphere.
Natural gas also has a higher ignition temperature. This means that it is much harder to ignite. The storage systems used for compressed natural gas are infinitely stronger that the gasoline tanks found on cars and trucks today.
