Why the EU should ban SF6

May 21, 2018· SF6, the most potent greenhouse gas in existence, was banned for all appliions in the EU in 2014 – except in the electricity industry. The reason for the exemption, writes Nicholas Ottersbach, researcher, that there was no viable alternative. But according to Ottersbach that is no longer the case.

Increasing demand for an alternative insulation medium to sulphur hexafluoride (SF6) has led to the investigation of new environmentally friendly insulation gases which could be used in high voltage equipment on the electrical power network. One such alternative, which is currently being explored by researchers, is Trifluoroiodomethane (CF3I) which could potentially be used in a gas mixture

“Besides removal of the by-products, we have two main options under investigation: either to reuse the gas and keep the ratio of the original gas; or separate the components and subsequently re-mix them for further use. We already have long-term experience with gas mixtures, such as N2/SF6 or CF4/SF6, so a similar process is foreseen.”

Myth About SF6 Gas In Electrical Equipment

3. Is SF6 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. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
