What are the differences and advantages between LNG and CNG?

[LeGrace]

Both are natural gases with the same main components. The differences and advantages between LNG and CNG lie in their states of existence and safety hazards. State of existence: When natural gas is cooled to approximately -162°C under normal pressure, it changes from a gaseous state to a liquid state, known as Liquefied Natural Gas (LNG). On the other hand, Compressed Natural Gas (CNG) is natural gas that is pressurized and stored in containers in a gaseous state. Safety hazards: The primary methods for storing and transporting natural gas are through Compressed Natural Gas (CNG). Due to the high pressure of CNG, it poses many safety hazards, such as a higher risk of fire. In comparison, Liquefied Natural Gas (LNG) has a higher ignition point—auto-ignition temperature of about 590°C—a narrower explosion range (5%~15%), is lighter than air, and easier to disperse, making it safer.
