Scientists turn CO2 ‘back into coal’ in breakthrough carbon capture experiment

Scientists have managed to turn CO2 from a gas back into solid “coal”, in a breakthrough which could potentially help remove the greenhouse gas from the atmosphere.
The research team led by RMIT University in Melbourne, Australia, developed a new technique using a liquid metal electrolysis method which efficiently converts CO2 from a gas into solid particles of carbon.
Published in the journal Nature Communications, the authors say their technology offers an alternative pathway for “safely and permanently” removing CO2 from the atmosphere.
Current carbon capture techniques involve turning the gas into a liquid and injecting it underground, but its use is not widespread due to issues around economic viability, and environmental concerns about leaks from the storage site.
The new technique results in solid flakes of carbon, similar to coal, which may be easier to store safely.
