Unlock the potential of compressed natural gas (CNG)—an abundant, low-emission alternative to gasoline and diesel. As a versatile energy source, CNG is playing a growing role in the shift toward cleaner, more sustainable operations across industries. It can be the foundation for your long-term sustainability strategy with proven efficiency and cost-effectiveness.
Natural gas is a byproduct of oil drilling and coal mining but can also be independently harvested from natural gas fields. It is used as a motor fuel in two forms, compressed natural gas (CNG) and liquefied natural gas (LNG).
Natural gas has been safely used as a transportation fuel across the world for many decades. It is lighter than air and thus much less volatile than gasoline or diesel. In the event of a leak, natural gas wants to quickly rise away from the scene rather than pooling like liquid hydrocarbon fuels. Because natural gas is stored in vehicles at high pressure, CNG tanks and systems are required to pass extensive tests and meet rigorous industry standards prior to operation. As a result, a Quantum Type 4 tank is actually more resistant to penetration than liquid fuel tanks used in production vehicles.
Natural gas is lighter than air. If a leak were to develop, the gas would rise and disperse into the atmosphere, giving little chance for ignition. Gasoline and diesel fuel, on the other hand, are dense liquids that tend to pool and catch fire easily. When CNG is burned, it produces few emissions as compared with gasoline or diesel, meaning less smog and less air pollution. This makes CNG a promising motor fuel for the future.
Traditionally, pipeline natural gas comes from deep underground wells and is associated with petroleum production. RNG, on the other hand, is natural gas derived from organic waste material found in daily life, such as food waste, garden and lawn clippings, and animal and plant-based material.
Raw natural gas is odorless, so a distinctive sulfur-scented odor is added prior to distribution. This strong smell makes it easier to detect a leak. If you notice an odor, please inspect the vehicle for the source of the concern and then repair as needed. Note that the odorant becomes detectable at a concentration of approximately 1% by volume. However, the smell does not get stronger as the concentration increases. This means if you can smell it, the concentration is already at least 1%.
