Liquefied Natural Gas

Liquefied natural gas is made by purifying, then super-cooling, natural gas to negative 260 degrees Fahrenheit. During this process, many elements are removed to yield methane.

After the liquefied natural gas is produced, it must be stored at extremely low temperatures in in a cryogenic tank – a challenge what has limited its widespread use. The U.S. Department of Energy reports that liquefied natural gas is primarily used in medium- and heavy-use commercial trucks, rather than passenger vehicles.
