Preparation of an international initiative to mitigate sulphur hexafluoride emissions in the power sector

Context

Sulphur hexafluoride (SF6) is the most climate-damaging known greenhouse gas, but it has so far been given little attention in the field of international climate protection. In particular, SF6 escapes from gas-insulated switchgear in the power infrastructure. Because grids and renewable energies are being expanded, emissions are threatening to rise sharply, especially in developing countries and emerging economies. In addition, many old systems are reaching the end of their service life, meaning that the operators have to recycle or dispose of the contained SF6 properly. To do so, grid operators require trained personnel and awareness.

Objective

The Federal Ministry for Economic Affairs and Climate Action (BMWK) is ready to launch an international initiative to reduce SF6 emissions in the power industry worldwide.

Approach

Together with the BMWK, the project is preparing the international initiative to reduce SF6 emissions in the power grid.

To achieve this, it is initially working with the think tank ‘Perspectives Climate Research’ to prepare a technology analysis that includes specific infrastructure solutions and financing instruments. The analysis thus shows how SF6 emissions can be reduced and a switch to alternative technologies can be implemented successfully.

Based on this concept, the project determines the initial situation in potential cooperation countries. In doing so, it looks at the current infrastructure, practice, regulation, relevant institutions, resources, available data, nationally determined contributions (NDCs), awareness of the problem and political interest.

Finally, the project is preparing for the initiative to be embedded in international institutions. It contacts governments that can contribute to the dedicated, transnationally coordinated initiative.
