Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for insulating gas, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used sf 6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect sf 6 emissions from electric power systems, such as the type and age of the Sulfr hexafluoride-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of Sulfr hexafluoride, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of sf 6can impact the climate. The electric power industry uses roughly 80 percent of all insulating gas produced worldwide. Ideally, none of this gas would b...

Sulfr hexafluoride: The Truths and Myths of this Greenhouse Gas

Sulphur hexafluoride, commonly known as SF 6, has made a splash in the mainstream media of late. Several articles are pointing the finger at the growth in renewables—specifically wind turbines—as being responsible for the growth in SF 6 emissions, with some going as far as saying that the gas is the energy industry’s dirty little secret. In this spirit of transparency, we asked several experts from NTNU and SINTEF to separate the truths from the myths.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
