News Room : GE Grid Solutions

The key difference between g3 and insulating gas is that g3 is a gas mixture while sf 6 is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling equipment needs to directly heat up the g3 bottle to a specific temperature, to reach the supercritical state of the gas mixture.Get price

Have you Heard of the Most Powerful Greenhouse Gas we Know

Meet sf6 gas, 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 sf 6 (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, insulating 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 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
