sf6 gas: The Truths and Myths of this Greenhouse Gas

gaz sf6 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. sf 6 is the energy industry’s “dirty little secret”: FALSE. insulating gas 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 sf 6 is used in wind turbines: TRUE. Sulfr hexafluoride 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 sf6 gas: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on sf6 gas at low-to-medium voltage levels in the future.

Have you Heard of the Most Powerful Greenhouse Gas we Know

Meet Sulfr hexafluoride, 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 Sulfr hexafluoride (sulphur hexafluoride) is stronger than CO2 in terms of global warming potential. You read right: Sulfr hexafluoride 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
