Researchers in Australia have developed a new way to capture CO2 and convert it to solid carbon. The process has been developed in the laboratory and the next step will be to test it with a small prototype. It has the potential to provide a novel way to capture and store CO2.
Current approaches to carbon capture and storage (CCS) focus on compressing the CO2 gas into a liquid and then injecting it underground. This approach is expensive, often requires long pipelines from the source to the disposal site, and is energy-intensive. The new approach, if proven feasible at a large scale, uses less energy as the process does not require high temperatures.
A short video of the process can be seen on YouTube.
