insulating gas: The Truths and Myths of this Greenhouse Gas

insulating gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, gaz sf6 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. Sulfr hexafluoride 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 Sulfr hexafluoride is used in wind turbines: TRUE. sf6 gas 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 gaz sf6 at low-to-medium voltage levels in the future.

Sulphur hexafluoride (SF 6) is a greenhouse gas and has a very high radiative forcing effect and a GWP of 22,800 compared with a figure of 1 for carbon dioxide. Emissions occur due to its use in a small number of applications. Annual emissions have decreased by 58% since 1995.
