SF6 Breakers control of emissions prices

SF6 Breakers control of emissions prices

Nov 15, 2011Fugitive emissions – which are inadvertently released often through valve leaks or breaks – contributed approximately 14 percent of the Energy Department's Scope 1 and 2 total greenhouse gas emissions in 2008. The most common fugitive emission at Department sites is sulfur hexafluoride (SF6), a nontoxic gas used in electric insulation.
