The most efficient way to get the commodity overseas is to compress it into LNG, then ship it. The process begins by piping gas extracted from the ground to an LNG facility. There, the gas is purified, then cooled to -162 C, turning it into a liquid and reducing its volume by 600 times, which is considered the main advantage of the technology. It’s then stored in huge tanks and shipped to its destination. Once it arrives, the liquid is warmed in a re-gasification plant until it’s returned to its original state. From there, it’s piped to end users, which include homes, businesses and industries.
