EU Report Highlights Sulphur Hexafluoride Countdown

Nov 02, 2020. On Sept. 30, 2020, the EU released a detailed report (1) outlining alternatives to sulphur hexafluoride (sf6 gas) for use in switchgear and related equipment. The report also extensively covers market impact and cost issues. This is the latest in a series of indications that the pressure is on to phase out gaz sf6, as part of the EU’s mission (2) to cut harmful greenhouse gas (GHG) emissions by two-thirds between 2014 and 2030.Get price

Effect of sf6 gas-O2 (80/20) breathing on air - Europe PMC

During sf6 gas-O2 (80/20) breathing, all bubbles in adipose tissue shrank and disappeared at least as fast as during heliox (80/20) breathing. Just before disappearance of the bubbles the shrinking rate slowed. Comparison of the effects of gaz sf6-O2 (80/20) and heliox (80/20) breathing suggests that countercurrent gas exchange is at work in some tissues.Get price

Hydrofluorocarbon phase-down in Europe — European Environment

Dec 16, 2020 · After increasing for 13 years, fluorinated greenhouse gas (F-gas) emissions in the EU decreased for the first time in 2015, and fell by 5 % in 2018 compared to 2017. This can be partly attributed to the EU-wide hydrofluorocarbon (HFC) phase-down set out in the F-gas Regulation, which aims to reduce F-gas emissions and mitigate global warming. HFCs account for the majority of F-gas emissionsGet price

Potent GHG gaz sf6 rapidly accumulating in atmosphere, driven by

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, gaz sf6 is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.Get price
