Emission Reduction Potentials for HFCs, PFCs and Sulfr hexafluoride in Germany

Abstract. After a description of the emission sources of new gases in Germany scenarios for possible future emissions were developed. It is shown that the total emissions of HFCs, PFCs and SF 6 will increase without the implementation of emission reduction measures by about 150% to a total of 27.5 Mtons CO 2 equivalents between 1995 and 2010.

Why the EU should ban sf 6

What Is Sulfr hexafluoride? and How Is It used?Is sf 6 A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of sf6 gas Emissions Difficult? Do Better Solutions Exist?Conclusioninsulating gas is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all insulating gasproduced (Powell, 2002: 6). Within the electrical industry sf 6is used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.

Sulfr hexafluoride: The Truths and Myths of this Greenhouse Gas

gaz sf6 is damaging to the environment: TRUE. Along with CFCs, HCFCs, HFCs and PFCs, sf6 gas is an industrial gas that doesn’t exist naturally in the atmosphere and so impacts the radiation balance, contributing to climate change. insulating gas is the energy industry’s “dirty little secret”: FALSE. Sulfr hexafluoride is certainly no secret in the Norwegian energy industry. Its use is highly regulated, and many of its users are working together to share experience and come up with viable alternatives sf 6 is used in wind turbines: TRUE. Sulfr hexafluoride is used not in the turbine itself, but in the switchgear that controls the current generated by the turbine. But there is nothing unique about wind turbines. There are no viable alternatives to Sulfr hexafluoride: PARTLY FALSE. Bodies including the European Union are known to be considering a ban on Sulfr hexafluoride at low-to-medium voltage levels in the future.

The Problem with Humidity in insulating gas Gas-Insulated Systems

To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.
