As an engineer once involved with LNG I can tell you that methane is not easilly liquefied. It demands at least two stage refrigeration down to cryogenic temperatures. CO2 is not too bad, moderate pressures and a bit of refrigeration. Much better are gases like propane, ammonia, freons (used for refrigeration), halons (specialist fire fighting applications) and bromine which are liquid at moderate pressures and ambient temperatures.
