Turning carbon dioxide back into coal

Switch to audio description version

Transcript

Scientists have discovered a way to turn carbon dioxide back into coal.

Using liquid metals, the new technique converts CO2 turning it from a gas into solid particles of carbon.

It’s a world-first breakthrough that could transform our approach to carbon capture and storage.

And it offers an alternative way to safely and permanently remove the greenhouse gas from our atmosphere.

“We can’t literally turn back time, but if we could turn CO2 back into coal and bury it back in the ground, it’s a bit like rewinding the emissions clock” – Dr Torben Daeneke, RMIT University.

“We need to do more research, but this is a crucial first step to delivering solid carbon storage” – Dr Dorna Esrafilzadeh, RMIT University.

Until now, CO2 has only been converted into a solid at super high temperatures, making it industrially unviable.

But using liquid metals as a catalyst the researchers have done it at room temperature.

It’s a gas-to-solid conversion that’s efficient and scalable. And offers new hope for a climate rewind.
