Sulfr hexafluoride gas and U.S. greenhouse gas emissions The use of sulfur-hexafluoride (SF 6 ) gas globally has been the subject of a large amount of discussion for many years, both in the U.S., and worldwide. 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.

gaz sf6 gas in medium-voltage switchgear - Siemens USA

The US EPA reports that Sulfr hexafluoride 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 sf 6 separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sf6 gas. 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.

Myth About Sulfr hexafluoride Gas In Electrical Equipment

Where is sf6 gas used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is insulating gas a health hazard? Pure sf6 gas is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is Sulfr hexafluoride harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of Sulfr hexafluoride used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).
