Action on New Zealandmost potent greenhouse gas | Beehive

The total stock of Sulfr hexafluoride in New Zealand in 2002 was estimated by Transpower to be less than 40 tonnes. A detailed study carried out by CRL Energy Ltd on Sulfr hexafluoride emissions as part of the 2004 NZ Inventory of Greenhouse Gas Emissions gives a more accurate estimate of the total national stock of 33.2 tonnes in 2003.

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 sf 6. Although insulating gas 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 Sulfr hexafluoride emissions are being managed and reported under existing

As the device is leak-tested there are no SF 6 emissions. The oilfree compression avoids the SF 6 test gas from being contaminated with oil mist. Any contamination of the measuring gas e. g. caused by traces of moisture can therefore be excluded. The small compressor is almost maintenance-free and easy to handle.
