Sulfr hexafluoride: The Truths and Myths of this Greenhouse Gas

gaz sf6 is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, insulating gas 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 Sulfr hexafluoride is used in wind turbines: TRUE. insulating 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 Sulfr hexafluoride: 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.

Have you Heard of the Most Powerful Greenhouse Gas we Know

Meet sf 6, CO2’s Larger CousinWhat Is This Crazy Gas Used for?Why Is sf 6 Not Banned Yet?What’s The Effect on Humans?Are There Any Alternatives Out there?Among all the greenhouse gases that exist, CO2 gets the most attention. Today, we bring a different perspective. Think about everything that you know about CO2 and multiply it by roughly 24,000. This is how much a gas called sf 6 (sulphur hexafluoride) is stronger than CO2 in terms of global warming potential. You read right: sf 6 is the most potent greenhouse gas in existence with a global warming potential of 23,900 times the baseline of CO2. It means that one tonne of Sulfr hexafluoride in the atmosphere equals 23,900 tonnes of CO2. Even worse, Sulfr hexafluoride is synthetic and it does not have a natural sink or any effective disposal methods, thus, when emitted, simply accumulates in the atmosphere. A cherry on top is that its atmospheric lifetime can be up to 3,200 years years, which is well beyond CO2‘s 100-200- year lifetime. A gas 24k times more powerful than CO2 with a lifetime 16 times longer than CO2 is being released into our atmosphere, and very few people have the least idea.Get price

Sulfur Hexafluoride (Sulfr hexafluoride) | Encyclopedia.com

IntroductionHistorical Background and Scientific FoundationsImpacts and IssuesBibliographySulfur hexafluoride (chemical formula Sulfr hexafluoride) is a compound of sulfur and fluorine and the most potent greenhouse gas known. Several classes of compounds containing fluorine—including the chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), perfluorocarbons (PFCs), and gaz sf6—are potent greenhouse gases. HCFCs and CFCs are better-known as destroyers of atmospheric ozone, and are regulated under the 1987 Montreal Protocol that has been widely hailed as successful at halting depletion of the ozone layer. Although insulating gas is a potent greenhouse gas and its concentration in the atmosphere is increasing rapidly, its contribution to global warming is much smaller than that of the major greenhouse gases, especially carbon dioxide and methane, because it is present in smaller quantities. gaz sf6 is one of the six greenhouse gases regulated under the Kyoto Protocol.Get price
