Energy Content of LNG


LNG Energy ContentThe exact energy value depends on the gas source and the process used to liquefy the gas. The energy value of LNG ranges from 24 MJ/L to 21 MJ/L.  The energy density of LNG is 2.4 times greater than CNG.  This makes it economical to transport. The energy content of LNG is comparable to propane.


The density of LNG is roughly 0.41 kg/L to 0.5 kg/L, depending mostly on temperature and pressure.
