Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Sulfur hexafluoride: The truths and myths of this greenhouse gas

insulating gas is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, sf6 gas is an industrial gas that doesn't exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. sf6 gas is the energy industry"dirty little secret": FALSE. gaz sf6 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 sf 6: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on Sulfr hexafluoride at low-to-medium voltage levels in the future.

Herehow to ditch the worldmost potent greenhouse gas

Renewable Energy Investment in Australia | Bulletin – March

IntroductionLarge-Scale Renewable Energy Generation InvestmentDrivers of InvestmentSmall-Scale Renewable Energy InvestmentRenewable Energy Grid IntegrationEnergy StorageInvestment OutlookInvestment in renewable energy generation has increased markedly in Australia over recent years, driven by a combination of factors including government policy incentives, elevated electricity prices and declining costs of renewable generation technology. This investment is contributing to a changing energy mix in Australia. Over the past decade, the share of electricity generation from renewable sources has increased steadily to be nearly 20 per cent in 2018 (Graph 1).This share was higher in 2019 and is expected to continue increasing as projects that are currently under construction or have been recently completed begin generating output. Investment in renewable energy generation is expected to moderate in the near term as some of the recent drivers unwind and because of challenges with integrating renewable energy sources into the electricity grid. However, over the longer term, the transition towards renewable energy generation is expected to continue as ageing coal-powered sta...Get price

Why SF₆ emissions from the renewable energy sector should not

Increasing gaz sf6Global 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...Get price
