Sulfr hexafluoride: The Truths and Myths of this Greenhouse Gas

sf6 gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, sf 6 is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. sf6 gas is the energy industry’s “dirty little secret”: FALSE. insulating gas is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives gaz sf6 is used in wind turbines: TRUE. Sulfr hexafluoride is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to insulating gas: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on Sulfr hexafluoride at low-to-medium voltage levels in the future.
