RMIT University researchers are rewinding the clock on carbon emissions

Researchers at RMIT University in Melbourne, Australia, have developed a technology that could change our approach to carbon capture and environmental sustainability.

The technology is a method to efficiently convert CO2 from a gas into solid particles of carbon. The method could be used to safely and permanently remove the greenhouse gas from our atmosphere.

Current technologies for carbon capture and storage focus on turning CO2 into a liquid form and injecting it underground, but these methods have been met by challenges in engineering, economic viability, and environmental damage. The new method, according to RMIT researcher Torben Daeneke, could be a more sustainable approach.

“While we can’t literally turn back time, turning carbon dioxide back into coal and burying it back in the ground is a bit like rewinding the emissions clock,” says Daeneke. “While more research needs to be done, it’s a crucial first step to delivering solid storage of carbon.”

Dorna Esrafilzadeh, head of the RMIT research team, says the technology could even lead to a new, more sustainable source of energy.

“A side benefit of the process is that the carbon can hold electrical charge, becoming a supercapacitor, so it could potentially be used as a component in future vehicles,” says Esrafilzadeh. “The process also produces synthetic fuel as a byproduct, which could also have industrial applications.”
