Let’s Look at Three Options to Improve Gas System Resiliency
Evolving state regulations and ongoing emissions tracking under the greenhouse gas reporting program are prompting utilities to transition away from sulfur hexafluoride (SF₆). Used extensively in high-voltage equipment for its reliable insulating properties, SF₆ is now under elevated scrutiny due to its global warming potential, which is 23,500 times that of carbon dioxide, and an atmospheric lifetime exceeding 3,000 years. Despite representing a small share of total greenhouse gas emissions, SF₆ from the electric power sector accounts for the majority of U.S. emissions from fluorinated gases.
