• b) provide cold energy to a volume of gas at above the liquefaction temperature in a liquefaction system at a second location.

A method of delivering liquefied natural gas (LNG), comprising:

• flowing LNG to a heat exchange apparatus from an LNG storage tank on an LNG carrier at an LNG gasification location;
• recovering cold energy from the LNG using the heat exchange apparatus having a regenerator matrix including a volume of high heat capacity materials to form at least partially vaporized natural gas;
• storing the cold energy in the high heat capacity materials for use at an LNG liquefaction location;
• and
• delivering the at least partially vaporized natural gas to a consuming market.
