Background on the technology and the terms used on this page.

LNG against pipeline gas
A pipeline delivers gas at lower cost than LNG over land up to roughly two to four thousand kilometres, beyond which liquefaction wins, and across any significant body of deep water LNG usually wins at any distance.
How LNG works
Liquefied natural gas is natural gas chilled to about minus 162 degrees Celsius, at which point it becomes a liquid roughly 600 times smaller than the gas, so it can be shipped where no pipeline runs.
Mtpa, bcm and cubic metres
LNG capacity is quoted in three incompatible units, and the two conversions that matter are 1 million tonnes a year equals about 1.36 billion cubic metres of gas a year, and 1 cubic metre of liquid equals about 600 cubic metres of gas.
What terminal status actually means
A project status describes how far an LNG terminal or train has progressed, and the gap between proposed and operating is the single most misread number in the industry.
