SF₆ Knowledge Hub

 

Through this SF₆ Knowledge Hub, the CTCN brings together its technical assistance, projects, guidance materials, and partnerships supporting developing countries in addressing SF₆ emissions. The hub also provides entry points for stakeholders to learn, engage, and access CTCN support.

 

Context

Sulfur hexafluoride (SF₆) is the most potent greenhouse gas with a global warming potential of more than 24,000 times that of CO₂ and an exceptionally long atmospheric lifetime. It is mostly used in electrical transmission and distribution infrastructure as an isolating gas. 

Managing existing SF₆-containing equipment, and planning a transition to available alternatives present significant technical and institutional challenges, particularly for developing countries. These challenges require practical solutions, capacity building, and access to relevant experience and technologies.

 

SF₆ Transition Community

The SF₆ Transition Community, an initiative of the Knowledge Hub, is a global knowledge exchange platform to support the safe management and phase-out of sulfur hexafluoride (SF₆) in the power sector.

The Community brings together stakeholders from government, industry, finance, international organizations, civil society, and academia to share challenges, best practices and lessons learned, and accelerate the transition to SF₆-free alternatives through peer learning and collaboration with the aim of advancing: 

  • Technologies to monitor SF₆ related GHG emissions 
  • Lessons learned from pioneering countries and technologies 
  • Robust policy and regulatory frameworks 
  • Safe and effective SF₆ management practices across the lifecycle 
  • The transition towards modern, reliable, and low-carbon SF₆-free power grids 

​If you are interested in joining this Community, please contact CTCN at [email protected]
