The cost-effective method could revolutionize how we remove carbon from the atmosphere, particularly in regard to climate change.

Scientists have created a method to convert carbon dioxide back into solid coal, a breakthrough that could change the ways carbon is removed from the atmosphere and permanently stored.

It’s one of several recently developed negative emissions techniques that seek to make carbon capture and storage cheaper, safer and more efficient. This particular method was developed by a research team led by RMIT University in Melbourne, Australia, and it uses a liquid metal electrocatalyst, containing nanoparticles of the rare-earth metal cerium, to convert the greenhouse gas into a stable, coal-like solid.
