Siemens Gamesa plans to phase out the usage of sulphur hexafluoride, or SF6 – a "climate-killing" fluorinated gas (F-gas) used as insulation material in switchgear – from its products by 2030.

The wind turbine manufacturer said the colourless, odourless, synthetic gas is used as an effective insulating material for medium and high-voltage electrical installations to prevent short-circuits and accidents, and is a standard component in any electrical management device.

But it has also been identified as one of the world’s most potent greenhouse gases which stays in the atmosphere and warms the earth for at least 1,000 years, and the European Commission has proposed to completely phase it out in switchgear by 2030.
