sf6 gas Worries – The Most Potent and Persistent Greenhouse Gas

Sep 20, 2019 · While SF 6 concentrations are about 10 parts per trillion in Earth’s atmosphere and projected to rise (see Figure 2), taking into account its greater global warming potential relative to CO 2 brings it to an effective concentration of 240 parts per billion (CO 2 equivalents), which is just about 1000 times less than the present-day levels of CO 2 of around 410 parts per million.

insulating gas: The Truths and Myths of this Greenhouse Gas

Sulphur hexafluoride, commonly known as SF 6, has made a splash in the mainstream media of late. Several articles are pointing the finger at the growth in renewables—specifically wind turbines—as being responsible for the growth in SF 6 emissions, with some going as far as saying that the gas is the energy industry’s dirty little secret. In this spirit of transparency, we asked several experts from NTNU and SINTEF to separate the truths from the myths.
