The U.S. has been at the forefront of international LNG trade since its inception. The first shipload of LNG was delivered by the Methane Pioneer in 1959 from Lake Charles, La., to Canvey Island, U.K..

Ten years later in 1969, the Kenai LNG plant in Alaska, owned by Phillips Petroleum Co. and Marathon Inc., shipped the first LNG cargo to Japan, opening up the LNG trade to Asia. The Kenai plant,small by today’s standards at only 1.5 million metric tons per year (mt/y) [equal to 210 million cubic feet per day (MMcf/d)], was the largest LNG plant at that time and continued operation until the final cargo was sent in 2015.
