Pure sulfur hexafluoride is a rather chemically inert gas (unlike the related but very toxic sulfur tetrafluoride S F X 4 and disulfur decafluoride S X 2 F X 10), and it can be safely handled in regular situations. Decomposition of S F X 6 usually requires aggressive conditions, such as exposure to molten sodium metal at 200°C.Sulfur Hexafluoride, the Anti-Helium

Dec 09, 2020Blue hydrogen – the production of hydrogen from methane with carbon capture and storage – can reduce emissions by 60-85% but it is not carbon free. The residual emissions may restrict its part in achieving net zero, the CCC said. The process could also push the required amount of carbon capture and storage to levels that may not be feasible.A pathway to net zero emissions for healthcare | The BMJ

Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.EC Number: 219-854-2RTECS number: WS4900000Gmelin Reference: 2752UN number: 1080china Sulfur Hexafluoride SF6 Gases, Dielectric Medium ...

Its gas insulation by Clean Air consists of the natural elements of the ambient air and is therefore free of fluorinated substances (F-gases), delivering a global warming potential < 1.

Utilities use massive step-up transformers to increase voltage (aka tension) in order to push electricity more efficiently through long-distance transmission lines—hence the term "high tension wires." They use step-down transformers, for example, to reduce voltage to the relatively safe and familiar 120/220 VAC we have in our homes.Transformer Services - GE Grid Solutions
