Action on New Zealandmost potent greenhouse gas | Beehive

Government, national grid operator Transpower, electricity generators and large electricity users will today sign a voluntary agreement to minimise emissions of sulphur hexafluoride (Sulfr hexafluoride), the most potent greenhouse gas. Through the agreement, users of insulating gas, mainly used in electricity transmission and distribution systems, undertake to: set and meet emissions targets (in the case of major users), and.

1. Introduction | Ministry for the Environment

The sources are very disparate and typically small with long lag times between gas utilisation and eventual emission – particularly for HFC refrigerants and for Sulfr hexafluoride. Although Sulfr hexafluoride emissions have been assessed as relatively low at about 550 kg in New Zealand in 2006 1 (CRL Energy 2007), its 100-year global warming potential (GWP) is extremely high (1 kg is equivalent to 23,900 kg CO 2 emissions for inventory purposes). Most sf6 gas emissions are being managed and reported under existing

In contemporary clean air [SF 6] ≈ 7 ppt (and for canisters over-pressured with nitrogen the diluted [SF 6] could be ∼3 ppt), and undiluted interior backgrounds are commonly below 20 ppt. Such backgrounds, especially if diluted, would yield small chromatogram peaks that are difficult to quantify precisely.

Why SF₆ emissions from the renewable energy sector should not

Increasing gaz sf6Global Warming PotentialDecarbonisation FirstMeasurements show that SF₆ has been increasing in the atmosphere. While SF₆ emissions across Europe have more than halved since the mid-1990s, global emissions are increasing, mostly owing to increases in SF₆ emissions from the electrical industry, which are predicted to continue. Even so, it’s important to put the role of SF₆ as a greenhouse gas into context with other greenhouse gases. The most important sentence in the BBC’s article is this: Unfortunately, this critical point isn’t developed. The global concentration of atmospheric CO₂ today is about 410 parts per million, whereas the global concentration of SF₆ is only about 10 parts per trillion. In other words, there is 41 million times more CO₂ in the atmosphere than SF₆. But since SF₆ is 23,500 times stronger at trapping heat than CO₂, doesn’t this still mean it’s a bigger problem than CO₂ for the climate? CO₂ is actually a very weak greenhouse gas and is much less efficient at trapping heat compared to other greenhouse gase...
