Systems and methods for producing and storing pressurized liquefied natural gas (PLNG) are provided, wherein the systems and methods include (a) a natural gas processing plant suitable for producing PLNG; and (b) at least one container suitable for storing the PLNG, the at least one container comprising (i) a load-bearing vessel made from a composite material and (ii) a substantially non-load-bearing liner in contact with the vessel, said liner providing a substantially impermeable barrier to the PLNG. The systems and methods also preferably include (c) means for transporting the at least one container containing PLNG to an import terminal.
