Abstract

In this paper, the authors articulate the phaseout of sulphur hexafluoride (SF6) in the electrical high voltage (HV) insulated switchgear system. The main focus is on the transition to SF6 alternatives and compilation of existing research on the life cycle assessments (LCAs) of these technologies. Their potential for decarbonization is explored through comparative methodologies, optimal ways to reduce carbon footprints and enhance sustainability. By synthesizing the effects of these technologies on carbon footprints, the study underlines the role that revolutionary answers have in propelling decarbonization attempts in the electrical transmission sectors through innovative solutions which with broader climate change mitigation strategies. Subsequently, it undertakes a detailed comparative LCA evaluation of different aspects, indicators and approaches. Then, this process is followed through with a detailed interpretation of the impacts of the methods and assumptions used in calculating the final assessment results. Consequently, this interpretation emphasizes the most influential and transparent method regarding the product's environmental performance across its entire life cycle stages. The outcomes show that complete standardized LCA is necessary to effectively compare the ecological impact of various HV products and technologies. It allows related stakeholders to conclude the fairest LCA in their decisions and strategy towards decarbonization. There are also proposals and recommendations for future research and decision-making regarding future enhancements and improvements for comparable and accurate environmental assessments.
