LNG Overview: Advantages, Storage Solutions, and Limitations
LNG (Liquefied natural gas) is a liquid form of natural gas that is liquefied by reducing its temperature to about -162 degrees C. Due to very low temperature, LNG has a tendency to boil off. To overcome the problem, it has been stored in vacuum-insulated, double-walled, cryogenic storage tanks. LNG has a similar gas composition to CNG, the only difference is that LNG has been cooled down to a liquid stage for higher energy storage density, ease of transportation, and safety due to low-pressure storage. LNG is typically transported in specially designed cryogenic tanks installed on ships or trucks, and it is stored in insulated tanks at receiving terminals or facilities.
The primary benefit of LNG range enhancement compared to CNG, as the liquefaction process reduces the volume of natural gas. For a particular storage tank volume, LNG provides about three times longer vehicle range.
The liquefaction process of natural gas involves the removal of certain impurities such as dust, water, heavy hydrocarbons, etc. Due to impurities removal, LNG is slightly cleaner than CNG.
LNG also has multiple challenges such as gas boils-off, variation in gas composition over time, relatively high knocking tendency, etc.
