What is liquified natural gas (LNG)?

Liquefied natural gas (LNG) is specifically defined as natural gas that has been cooled to a liquid state. This process involves reducing the temperature of natural gas, primarily methane, to about -162 degrees Celsius (-260 degrees Fahrenheit). In this liquid form, natural gas occupies about 1/600th of its gaseous volume, making it much more efficient to transport and store, especially over long distances where pipelines are not feasible.

The cooling process transforms the gas into a liquid without changing its chemical composition, which allows for easier handling and shipping. LNG is crucial for the global energy market, especially for countries that import natural gas, as it enables movement across oceans in specialized tankers.

This understanding is essential for those involved in CNG delivery, as it highlights the relevance of LNG in the broader context of natural gas usage and transportation.
