EU report on SF6 alternatives and potential SF6 phase out
The EU Commission (DG CLIMA ) has issued a new report on Sulphur Hexafluoride (SF6) alternatives and potential SF6 phase out scenarios related to the so-called F-gas regulation (EU Regulation 517/2014). Usage of SF6 has been banned already in multiple applications with electrical equipment being excluded from these restrictions up to now. The EU report (PDF 319 KB) is assessing the availability of SF6 alternatives and is giving an evaluation for a potential SF6 phase out.
EU stakeholder workshop discussing SF6 phase out scenarios
In a next step the EU Commission (DG CLIMA ) has invited related stakeholder including member states, switchgear OEM’s, utilities and NGO’s to discuss potential SF6 phase out timings. The workshop is based on the 2020 EU report and additional input the commission has received via direct consultation with related stakeholders. It is expected that the commission will issue a proposal for the revised F-gas regulation by the end of 2021 and the regulation will take effect end of 2022/beginning of 2023. It is therefore time to act and to start implementing suitable SF6 alternatives!
In addition, a recent study conducted by the University of Antwerp concluded that the reported SF6 stock and emissions are significantly underestimated. The study also provides an estimate of CO2 eq savings for potential SF6 phase out scenarios using the example of a 145kV Gas Insulated Switchgear (GIS).

Novec Insulating Gases are the ideal SF6 alternative as they combine excellent dielectric performance and safety with exceptional environmental properties. Used as part of a gas mixture, Novec Insulating Gases reduce the greenhouse gas potential by more than 99% in on-grid commercial equipment.
Our partners are using Novec Insulating Gases as part of their SF6 free products in multiple medium- and high-voltage applications going back to first installations in 2015:
g3, (pronounced "g" cubed) is GE's game-changing alternative to SF6 gas, developed for HV electrical transmission equipment and is using 3M Novec 4710.
g3 products feature the same ratings and same dimensional footprint as the state-of-the-art SF6 ones, with a drastically reduced environmental impact.
