Researchers at the RMIT University at Melbourne, Australia have for the first time developed a process to turn CO2 into coal. Gaseous C02 can be converted in solid chunks of coal using this process. The new process uses liquid metal as a catalyst to permanently and safely convert CO2 into a solid form for storing. Current methods of carbon capture and storage involve compressing CO2 into a liquid and injecting it deep into the ground. This process is neither environmentally safe nor economically viable.
So far converting CO2 gas into solid carbon involved using extremely high temperature and could not be deployed at an industrial scale. But in this new process, CO2 can be converted to coal at room temperature making it an applicable technology.
Another advantage of this process is that the carbon produced can be used as electrodes paving its use in future electric vehicles.
This RMIT process has been the most promising breakthrough for carbon sequestration until now.
