'Secret' gas boosts climate warming

Electrical industry's 'dirty secret' boosts warming

It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years, the BBC has learned.

Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents. But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road.

Levels are rising as an unintended consequence of the green energy boom. Cheap and non-flammable, SF6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations. It is widely used across the industry, from large power stations to wind turbines to electrical sub-stations in towns and cities. It prevents electrical accidents and fires.

Across the entire UK network of power lines and substations, there are around one million kilograms of SF6 installed.

A study from the University of Cardiff found that across all transmission and distribution networks, the amount used was increasing by 30-40 tonnes per year.

This rise was also reflected across Europe with total emissions from the 28 member states in 2017 equivalent to 6.73 million tonnes of CO2. That's the same as the emissions from 1.3 million extra cars on the road for a year.

Researchers at the University of Bristol who monitor concentrations of warming gases in the atmosphere say they have seen significant rises in the last 20 years.

"We make measurements of SF6 in the background atmosphere," said Dr Matt Rigby, reader in atmospheric chemistry at Bristol.

"What we've seen is that the levels have increased substantially, and we've seen almost a doubling of the atmospheric concentration in the last two decades."

Concentrations in the atmosphere are very small right now, just a fraction of the amount of CO2 in the air.

However, the global installed base of SF6 is expected to grow by 75% by 2030. Another concern is that SF6 is a synthetic gas and isn't absorbed or destroyed naturally. It will all have to be replaced and destroyed to limit the impact on the climate.

Love that people think problems don't exist outside of America :bradley:

And this is why we have to be more thoughtful about synthetics. Nature doesn’t have a way to deal with them. Just like when we use pesticides... where does that all go? In the ground. Where do we get our drinking water? FROM THE GROUND

We can still blame Trump :ohwell:

We won't be right but that hasn't stopped people from believing things before :ohwell:

OT: humans destroying the Earth?! :udidnt: no! :udidnt: never! :udidnt:

It's fun stuff.

 

Yeah ive seen it used like that, found it kinda unexpected that it can become a greenhouse when its that heavy. I figured it would just stay on the ground

Well it does make you wonder if that gas is also "secretly" produced in the US.

yeah,  we kinda get tunnel vision here in the us … its not intentional tho,  

like a cat in a sil, I observe life, moving and still. My words give a clue,look inside to see whats true

its not that this problem was hatched by evil co...  but regulations need to be erected to get the problem fixed.
