Burying Carbon – how we can lock CO2 underground to combat climate change

Carbon dioxide (CO₂) is the main driver of climate change, but our world still depends heavily on fossil fuels and industries that produce it. One solution is to capture CO₂ and store it deep underground in rocks where it can remain safely for millions of years.

But, how do we know how long it can be stored for and that it will stay there?

This talk explores how we can use natural underground CO₂ reservoirs and chemical “fingerprints” to understand how to safely store CO2 and how it can react to turn into new rock.

This lecture, delivered by Dr Stuart Gilfillan, introduces the topic.
