I'm an expert in the field of energy and environmental sciences, and I'm here to provide you with a comprehensive understanding of LNG and CNG.
Liquefied Natural Gas (LNG) is natural gas that has been converted to liquid form for ease of storage and transportation. The process of liquefaction involves cooling the gas to extremely low temperatures, typically around -162°C (-260°F), which reduces its volume by approximately 600 times. This transformation allows for the efficient transportation of natural gas over long distances, often via specialized LNG carriers. Once it reaches its destination, the LNG is regasified by warming it up, returning it to its gaseous state, and then it can be distributed through pipelines or used directly.
Compressed Natural Gas (CNG), on the other hand, is a form of natural gas that has been compressed to less than 1% of its volume at standard atmospheric pressure. This is achieved by compressing the gas to high pressures, usually between 2,400 to 3,600 psi (pounds per square inch). CNG is commonly used as a fuel for vehicles, but it can also be used in industrial applications and for heating and electricity generation. The use of CNG in vehicles is beneficial because it is cleaner burning than gasoline or diesel, resulting in lower emissions.
One of the key aspects of natural gas safety is the addition of an odourant to the gas. This is particularly important for CNG, as natural gas is odorless and colorless, making leaks difficult to detect without the aid of such additives. A sulphur-based odourant is typically used to give the gas a distinct smell, which helps in the early detection of leaks and enhances safety measures.
Another safety advantage of natural gas, both in its LNG and CNG forms, is that it is lighter than air. This means that in the event of a leak, the gas will tend to rise and disperse into the atmosphere, reducing the risk of a dangerous buildup of gas in confined spaces. This is a significant safety benefit when compared to heavier fuels like gasoline or LPG, which can pool and create a more immediate hazard.
In summary, LNG and CNG are both forms of natural gas that have been processed for specific applications. LNG is super-cooled for efficient long-distance transportation and storage, while CNG is compressed for use as a fuel in vehicles and other applications. Both forms of natural gas offer environmental and safety benefits, including cleaner emissions and a lower risk of hazardous gas buildup due to their lighter-than-air nature.

A sulphur-based odourant is normally added to CNG to facilitate leak detection. Natural gas is lighter than air and thus will normally dissipate in the case of a leak, giving it a significant safety advantage over gasoline or LPG. Liquefied Natural Gas or LNG is natural gas stored as a super-cooled (cryogenic) liquid.
