Sulfr hexafluoride: The Truths and Myths of this Greenhouse Gas

insulating 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. Sulfr hexafluoride is the energy industry’s “dirty little secret”: FALSE. sf 6 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 insulating gas 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 Sulfr hexafluoride: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on sf6 gas at low-to-medium voltage levels in the future.

Relevance of insulating gas in Switchgear and its Contribution to

Check out more market insights on our blog. Greenhouse Gases. Before jumping into those details, lets first take a step back and understand the rightful concern regarding the negative impact of sf6 gas on our environment. Greenhouse gases (GHG) are a group of compounds which can trap heat in the atmosphere which results in a warmer earth surface.

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, insulating gas is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.
