Review assesses eco-friendly replacement gases for electrical equipment insulation, highlighting technical trade-offs and crucial data gaps regarding chemical dissociation products.

Key Points

Evaluate the environmental impact of industrial sulfur hexafluoride emissions from electrical grids and assess the viability of emerging eco-friendly insulating replacement gases.
Reviewed the technological history and atmospheric accumulation of sulfur hexafluoride (SF6) across high-voltage transmission and distribution systems.
Synthesized available dielectric, chemical, and environmental performance data for the latest generation of alternative insulating gas candidates.
Widespread deployment of SF6 in compact power infrastructure has driven a continuous increase in atmospheric concentrations of the potent greenhouse gas over recent decades.
Novel replacement gases offer substantial potential to mitigate greenhouse gas emissions from electrical equipment, though their adoption introduces engineering trade-offs.
Designating any single eco-friendly gas as superior remains premature due to insufficient dielectric, toxicological, and chemical stability data concerning operational dissociation products.
