Get PriceGreenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (SF6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on SF6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to-date. Over a 100-year period, SF6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of carbon dioxide (CO2). SF6 is also a very stable chemical, with an atmospheric lifetime of 3,200 years. As the gas is emitted, it accumulates in the atmosphere in an essentially un-degraded state for many centuries. Thus, a relatively small amount of SF6can have a significant impact on global climate change. More information on long-lived fluorinated greenhouse gases, their emissions, emission sources, and trends is available on EPA's overview of greenhouse gases page.See more on epa.govManaging SF6 Gas Inventory and Emissions epa.gov/sites/production/files/2016-02/documents/conf...Managing SF6 Gas Inventory and Emissions Implementing Digital SF6 Tracking Solutions Chase Sanders csanders
