Description
Liquefied Natural Gas (LNG) is a clean-burning, odourless, colourless, and non-corrosive fuel created by cooling natural gas to approximately -162°C (-260°F) at atmospheric pressure.
This cryogenic process reduces its volume by about 600 times, making it highly efficient for storage and long-distance transport, particularly where pipeline infrastructure is not feasible.
Composed primarily of methane (CH₄), LNG may also contain small amounts of ethane, propane, butane, nitrogen, and other hydrocarbons.
LNG is considered one of the cleanest fossil fuels, with significantly lower carbon dioxide (CO₂), sulphur oxide (SOx), nitrogen oxide (NOx), and particulate emissions compared to coal or oil.
