LNG is a commonly used acronym for liquefied natural gas, essentially natural gas that is put into liquid form, often for the purpose of transportation.
For international trade, LNG is sent in insulated tanker ships using refrigeration that keeps the liquefied natural gas at a chilly -260 degrees Fahrenheit. Global shipments travel to receiving terminals on a daily basis where pipelines are then used to provide this clean-burning energy source to homes, schools, businesses and government buildings. More receiving terminals are being built around the world each year.
In the U.S. there is growing debate over LNG exports, some of which could come from the Marcellus and Utica shale formations found in Pennsylvania, West Virginia and Ohio.
The Energy Information Administration estimates that in just three years natural gas supply could exceed demand, allowing the U.S. to be a net exporter of LNG. Bipartisan support for such exports has grown to include local and national politicians; most recently, more than 100 members of the House of Representatives signed onto a letter to Department of Energy Secretary Steven Chu that asked the Obama administration for advance LNG exports without delay.
