Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

A recent study suggests that the UK’s use of Sulfr hexafluoride 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.

What Is Sulfr hexafluoride? and How Is It used?Is sf6 gas A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of sf 6 Emissions Difficult? Do Better Solutions Exist?Conclusionsf 6 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 sf6 gasproduced (Powell, 2002: 6). Within the electrical industry insulating gasis 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.

Analysis: Why the UK’s CO2 emissions have fallen 38% since

The Big PictureAnalysing Emission ReductionsElectricity GenerationTransportationBusiness, Residential and Other CO2 SourcesEmissions Embodied in TradeConclusionsMethodologyUK emissions have declined from around 600m tonnes of CO2 (MtCO2) in 1990 to 367MtCO2 in 2017. If underlying factors driving emissions had not changed, Carbon Brief’s analysis shows that a growing population and a constant electricity generation mix would have led to emissions increasing by around 25% compared to 1990 levels. Instead, emissions actually fell by 38% to 367MtCO2, as shown in the black area in the figure below. Each coloured wedge in the figure shows one factor contributing to this decline. As the chart shows, no single factor was responsible for more than around a third of the total reduction in the UK’s CO2. Overall, emissions in 2017 were 51% lower than they would have been without these changes Decreases in CO2 emissions from electricity production is one of the main drivers economy-wide (dark blue wedge), accounting for around 36% of the total emissions reduction in 2017.

gaz sf6: The Truths and Myths of this Greenhouse Gas

insulating gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, Sulfr hexafluoride is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. gaz sf6 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 insulating gas is used in wind turbines: TRUE. sf 6 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 sf 6 at low-to-medium voltage levels in the future.

Why SF₆ emissions from the renewable energy sector should not

Increasing insulating gasGlobal Warming PotentialDecarbonisation FirstMeasurements show that SF₆ has been increasing in the atmosphere. While SF₆ emissions across Europe have more than halved since the mid-1990s, global emissions are increasing, mostly owing to increases in SF₆ emissions from the electrical industry, which are predicted to continue. Even so, it’s important to put the role of SF₆ as a greenhouse gas into context with other greenhouse gases. The most important sentence in the BBC’s article is this: Unfortunately, this critical point isn’t developed. The global concentration of atmospheric CO₂ today is about 410 parts per million, whereas the global concentration of SF₆ is only about 10 parts per trillion. In other words, there is 41 million times more CO₂ in the atmosphere than SF₆. But since SF₆ is 23,500 times stronger at trapping heat than CO₂, doesn’t this still mean it’s a bigger problem than CO₂ for the climate? CO₂ is actually a very weak greenhouse gas and is much less efficient at trapping heat compared to other greenhouse gase...
