What is LNG?
Liquefied natural gas (LNG) is natural gas that has been cooled to its liquid state, at about -260 degrees Fahrenheit, for shipping and storage. The volume of LNG is about 600 times less than the gas, making it possible to transport large quantities of gas to places pipelines may not reach. The process to liquefy natural gas was developed in the 19th Century, and has been used in the United States since the 1940s. Many communities rely on LNG as a supplemental source of natural gas during peak times; more than 78 percent of New England’s energy on the 10 coldest days of the year comes from LNG.
