sf6 gas: The Truths and Myths of this Greenhouse Gas

Sulphur hexafluoride, commonly known as SF 6, has made a splash in the mainstream media of late. Several articles are pointing the finger at the growth in renewables—specifically wind turbines—as being responsible for the growth in SF 6 emissions, with some going as far as saying that the gas is the energy industry’s dirty little secret. In this spirit of transparency, we asked several experts from NTNU and SINTEF to separate the truths from the myths.

Have you Heard of the Most Powerful Greenhouse Gas - Plan A

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 insulating gas (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 gaz sf6 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.
