Emissions of the powerful greenhouse gas sf 6 are rising

A recent study suggests that the UK’s use of sf6 gas has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of Sulfr hexafluoride to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.

Pollutant information - NAEI, UK

Category: Greenhouse gases. 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. The largest source is related to the use of SF 6 for electrical insulation (47% of the total in 2018).

Arcing occurs within circuit breakers whenever they operate. This process causes the absorption and deceleration of electrons, which in turn causes partial decomposition of the SF 6 gas. One of the main reasons why SF 6 is used as an insulating gas is its ability to recombine the decomposition products and regenerate itself.

Do Better Solutions Exist?Conclusionsf6 gas is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all insulating gasproduced (Powell, 2002: 6). Within the electrical industry gaz sf6is used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.
