• insulating gas gas in medium-voltage switchgear - Siemens USA

    The US EPA reports that insulating gas has an atmospheric lifetime of around 3200 years, and a global warming potential (100-year horizon) of 23,900 times that of CO2. The EPA does no t report emission of Sulfr hexafluoride separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and Sulfr hexafluoride. The emissions of HFCs, PFCs, and gaz sf6 for 2000 are shown in the EPA report as having 2% of the global warming potential of all greenhouse gas emissions.

    SF 6 is recognized as an extremely potent greenhouse gas, primarily because of its atmospheric lifetime of about 3,200 years, with a global warming potential (GWP) of 22,800 years. The reference gas for GWP values is CO 2, which is assigned a GWP of 1.0. The EPA considers SF 6 as the most potent greenhouse gas that they have investigated. 1
