Decarbonisation Tech Instantly Converts CO2 to Solid Carbon
28th February 2022
Australian researchers have developed a smart and super-efficient new way of capturing carbon dioxide and converting it to solid carbon, to help advance the decarbonisation of heavy industries.

The “bubble column” method starts with liquid metal being heated to about 100-120C.
Carbon dioxide is injected into the liquid metal, with the gas bubbles rising up just like bubbles in a champagne glass.
As the bubbles move through the liquid metal, the gas molecule splits up to form flakes of solid carbon, with the reaction taking just a split second.
“It’s the extraordinary speed of the chemical reaction we have achieved that makes our technology commercially viable, where so many alternative approaches have struggled,” Chiang said.
