Liquefied Natural Gas (LNG) is a form of natural gas that has been cooled down to a liquid state at minus 162 degrees Celsius. This process reduces its volume by around 600 times, making it easier and more cost-effective to transport. LNG is mainly used as a fuel for vehicles, power generation, and heating. It is also a cleaner source of energy compared to traditional fossil fuels, producing lower levels of carbon dioxide and other pollutants when burned.
