Sulfr hexafluoride: The Truths and Myths of this Greenhouse Gas

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

Emissions of the powerful greenhouse gas insulating gas are rising

The amount of the gas – known as Sulfr hexafluoride – in the atmosphere is minute, only about three parts per trillion by volume, but its global warming potential is significant. It’s 23,500 times more warming than carbon dioxide.Get price

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 sf6 gas 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 CO2in terms of global warming potential. You read right: gaz sf6 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 sf 6 in the atmosphere equals 23,900 tonnes of CO2. Even worse, sf6 gas 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, 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 CO2is being released into our atmosphere, and very few people have the least idea.Get price
