Liquefied natural gas (LNG) is natural gas chilled to about -162° Celsius, the point at which natural gas condenses to become a liquid. The cooling process takes place in an LNG facility, similar to a large refrigerator.
LNG comes from the same natural gas used throughout Canada to heat our homes, schools and businesses; cook our food; and, increasingly, to fuel trucks, buses and ships. Even BC Ferries will soon have three new vessels powered by LNG. You can read more about that here and here.
One of the benefits of shipping LNG to overseas markets is enabling countries to displace coal when generating electricity, which leads to lower overall greenhouse gas emissions.
As for where LNG comes from, the gas used in LNG facilities in B.C. will come primarily from the northeastern region of our province, where it has been safely produced for generations.
