• Eliminating sulfur hexafluoride | 2021 | Siemens Energy Global

    A few years ago it might have been in your running shoes, your window insulation or in your tires: sulfur hexafluoride or SF 6 – the most potent greenhouse gas in the world, with a potential for global warming around 23,500 times greater than carbon dioxide. While manufacturers have since pulled SF 6 from shoes, windows and tires, tons of it are still being used to insulate high-voltage switchgear in substations around the world.
