New gases for GIS: reducing greenhouse gas emissions from the electrical grid

SF6 plays a key role in our current power system, particularly in gas-insulated substations (GIS). However, it is also one of the most potent greenhouse gases known to man. Therefore, we need to find an alternative. While there are gases that could replace SF6 in GIS, more research is still needed, and SF6-free technology is still at an early stage of development. These are knowledge gaps that SINTEF’s “New Gases for GIS” project hopes to fill.
