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.govEmissions Inventory Considerations for Supporting the, and sulfur hexafluoride. In addition, for the AZ CCMP process, a black carbon emissions inventory covering all sectors was also developed. These inventories are important elements of CCMP processes, as they are essential in identifying where emissions are headed and where opportunities lie for reducing emissions. In

Get Price09/06/2020A green alternative to SF6. The company identified an important step in its sustainability journey: to start removing SF6, a greenhouse gas that is harmful to the environment, from the MV switchgear installed on its networks. This was accomplished with SF6-free air-insulated MV switchgear that uses only air and vacuum, instead of SF6. It eliminates the need to use SF6 while retaining the same performance, physical footprint, and connections as traditional SF6 MV switchgear.
