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
