Other alternatives used or attempted include mixtures of SF6 with nitrogen, SF 6 /N 2 and different fluorinated gases but few meet the replacement criteria. Proprietary options are in development.

Sulfur hexafluoride (or SF6) is far from the most common gas that warms the planet, contributing around 1% of warming to date—carbon dioxide and methane are much more well-known and abundant.

EPRI’s research on potential strategies for SF6 replacement also extends to tracking and understanding the regulatory developments affecting SF6 and alternate technologies. Photo courtesy of EPRI.

SF6 or sulfur hexafluoride is an inorganic, colorless, inflammable, and potent greenhouse gas and an extraordinary electrical insulator.New York, Jan. 14, 2022 (GLOBE NEWSWIRE) ...

A 30-year, nationwide study of ecological changes — including the effects of climate warming — has been releasing a powerful greenhouse gas, and critics want it to stop.

The U.S. government is celebrating some success at reining in emissions of a potent greenhouse gas called SF6, which traps 25,000 times more heat than CO2 does over a century-long timescale ...

California proposes phasing out the use of SF6 in GIE and further reducing allowable GHG emissions from such equipment. California Air Resources Board (CARB) staff recently published a discussion ...

In the proposed regulation, New York will decisively phase-down SF6 in gas insulated equipment (GIE), by implementing emissions limits, utilization restrictions, and reporting requirements for ...

SF6 emissions from China nearly doubled from 2.6 gigagrams (Gg) per year in 2011 - when they accounted for 34 per cent of global emissions - to 5.1 Gg per year in 2021, when they amounted to 57 ...
