Both are natural gas with the same composition, but the state of existence is different.

CNG is compressed natural gas, which is natural gas-pressurized (over 3,600 psi) and stored in a container in its gaseous state.

LNG is liquefied natural gas. LNG is condensed into a liquid by cooling gaseous natural gas to -162°C under normal pressure. Liquefied natural gas can greatly save storage and transportation space and cost, and has the characteristics of large calorific value and high performance. LNG is a clean and efficient energy source.

Because importing LNG helps energy-consuming countries to diversify energy supply and ensure energy security, while exporting LNG helps natural gas producing countries to effectively develop natural gas resources, increase foreign exchange income, and promote national economic development, LNG trade is becoming a global energy market. new hotspot. CNG filling station includes mother station, standard station, and substation. The main refueling station generally takes gas from high-pressure pipelines to refill CNG cylinder trucks and then supplies gas to sub-stations through CNG cylinder trucks. At the same time, it has the ability to directly refuel CNG vehicles; Press the pipe network to take gas, and refill the CNG vehicle. LNG is liquefied natural gas, which is liquid, and CNG is compressed natural gas, which is gaseous. Both are natural gas but exist in different forms, the former is liquid and the latter is gas. LNG can be converted into CNG by gasification and then pressurization.
