Scientists Turn CO2 Back Into Coal
Current carbon capture methods transform the greenhouse gas into a liquid, but that’s expensive and doesn’t provide safe storage. Now, researchers in Australia say they’ve gotten liquid metals to convert gaseous carbon into solid form, according to a paper published in Nature Communications, allowing for secure underground storage. One researcher explained that the process is “efficient and scalable,” and a step toward “rewinding the emissions clock.”
Could the coal be used? Yes: Since it holds an electrical charge, it could be used as a supercapacitor for vehicles.
