Action on New Zealandmost potent greenhouse gas | Beehive

Where is Sulfr hexafluoride used? The main use of Sulfr hexafluoride globally is in electricity transmission and distribution systems. sf6 gas has excellent insulating properties and is the preferred insulator for high voltage electrical supply equipment such as: substations, gas-insulated switchgear and circuit breakers. This usage accounts for 80% of the total annual emissions.

The key difference between g3 and Sulfr hexafluoride is that g3 is a gas mixture while Sulfr hexafluoride is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling equipment needs to directly heat up the g3 bottle to a specific temperature, to reach the supercritical state of the gas mixture.
