    Nov 25, 2019 · 80% of all sf 6 is used in gas insulated switchgear, a vital component of the grid (isolating and protecting different sections), so it’s an energy sector issue. Nicholas Ottersbach at Nuventura (a cleantech startup developing ways to replace insulating gas) explains that alternatives exist, but need the help of robust regulations to accelerate further development and rapid take-up.

  • Electric Power Systems Partnership | Fluorinated Gas

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for insulating gas, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used insulating gasin circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect insulating gas emissions from electric power systems, such as the type and age of the sf6 gas-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of gaz sf6, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of sf6 gascan impact the climate. The electric power industry uses roughly 80 percent of all gaz sf6 produced worldwide. Ideally, none of this gas would b...
