[email protected]Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (gaz sf6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on gaz 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 gas is 22,800 times more effective at trapping infrared rSee more on epa.govSulfur Hexafluoride: The Nightmare Greenhouse Gas That's Just hackaday/2021/11/10/sulfur-hexafluoride-the-nightmare-greenhouse-gas-thats...10/11/2021In 2018, global emissions of SF 6 were 9.0±0.4 Gg yr −1, with 2018 CO 2 emissions being 33.1 Gt (33,100,000 Gg).
