ENVIRONMENTTECHNOLOGY[WATCH] Carbon Dioxide Turns Back Into Coal

Carbon dioxide emitted by vehicles, coal plants, and factories are being turned back into coal. Magic? It’s science.

Climate change gets worse by the minute. While storms lash the midwest part of the planet, the other side of the Earth endures drought and heat wave. Until now the debate over global warming is not over whether it is true or not.

Different environmentalists and conservationists around the world keep track of what is happening and find ways to counter the harmful effects of climate change. Most countries agree that the planet needs rehabilitation by conducting tree planting programs and recycling plastics while giving cryptocurrency as incentives. Other countries are cutting back on coal usage to reduce carbon dioxide in the atmosphere.

For the first time in history, researchers from RMIT University in Melbourne, Australia developed a new procedure that could transform carbon dioxide (CO2) back into pieces of carbon. This technique reduces pollution by eliminating greenhouse gases from the environment.

The proposition provides a more workable approach compared to the several methods of capturing carbon and storage systems that condense carbon dioxide into a liquid form that could be interspersed underground. The said approaches consist of numerous technical and safety issues which are likewise expensive.

“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,” said Dr. Torben Daeneke, RMIT researcher and an Australian Research Council DECRA Fellow.

The experimental approach is electrochemical consisting of uniquely-designed liquid metal catalyst that makes carbon dioxide from gas gradually turned into solid carbon flakes. The liquid metal cerium (Ce) catalyst has specific surface properties which makes it a perfect electrical conductor. Also, the current chemically triggers the surface of the catalyst.

According to Dr. Dorna Esrafilzadeh, one advantage of the technique is that carbon can grasp electrical charge that becomes a supercapacitor that can be possibly utilized as an element in future vehicles. She is also the paper’s lead author and Vice-Chancellor’s Research Fellow at RMIT’s School of Engineering.

The research, “Room temperature CO2 reduction to solid carbon species on liquid metals featuring atomically thin ceria interfaces” is published in the journal Nature.
