How do you convert CO2 to rock?

We're living in an age of rapid technological development which - alongside many benefits - comes at an environmental cost. We speak to Dr Shurui Miao, an experimental chemist who aims to decouple technological advancement from the impacts of increased carbon emissions, by finding a way to safely store carbon underground. As he explains, by finding a way to convert CO2 from the atmosphere into minerals, we could store carbon securely and sustainably into the future, and ultimately begin to mitigate the effects of climate change.
