LNG is natural gas refrigerated to a very low temperature and stored as a liquid.

Liquefied natural gas (LNG) is essentially natural gas in liquid form, having been reduced to a liquid state by a process of cooling to a temperature of minus 162°C.

Once it reaches the receiving facility, the LNG is transferred to special storage tanks, where it is kept in liquid form at near atmospheric pressure and temperatures of minus 160°C. It remains in storage until required for redelivery.
