How is LNG made?
The liquefaction process begins when natural gas is transported via pipeline to a liquefaction facility. There, components that will freeze at low temperatures (water, carbon dioxide, and heavier hydrocarbons) are removed and the remaining gas is chilled to about -260 degrees Fahrenheit, at which point the gas becomes a liquid. The LNG is then loaded onto specialized LNG carriers for transport. Some of the largest LNG tankers can carry enough natural gas to power 70,000 homes for one year.
When the LNG reaches an offloading facility, it may be regasified and then transported by pipeline to power plants for use in power generation; industrial facilities, for the manufacturing of steel, automobiles, and chemicals; and also homes and office buildings, for heating, cooking and drying clothes.
Alternatively, the offloading facility may load the LNG into a tanker truck, which will deliver it to a storage facility in its liquid state for use as a “peaking” fuel, which is fuel used to create power during periods of peak electricity demand, or to serve industrial and commercial end users that are not directly connected to the natural gas pipeline system, such as steel fabricators, fertilizer plants or chemical manufacturers.

U.S. LNG has been exported to over 25 countries and the list is growing. Follow along with our interactive map of U.S. LNG cargoes. By clicking on a country in green, you can find the date of the first export cargo, total volumes by year in Bcf, number of cargoes sent per year, which facility exported the gas, which vessel it was shipped on, and the date of every cargo sent out.
