MISSION – Emission-free HV and MV transmission switchgear for AC and DC

MISSION contributes to minimising both the use of fossil fuels and emissions of greenhouse gases into the atmosphere by

• Developing SF₆-free switchgear for AC and DC systems will enable emission-free energy transmission in a resilient and sustainable electric grid.

The SF₆-free switchgear components are for use in the future AC and DC systems. They will enable emission-free energy transmission in a resilient and sustainable electric grid. Most of today’s MVAC and HVAC switchgear is filled with the insulation gas SF₆ (sulphur hexafluoride). This is the most potent greenhouse gases: SF₆ is 24 300 worse than CO₂. SF₆ represents a significant part of grid owners’ emissions due to leakages when handling the gas or defective seals in the installations where the gas is used.
