VIDEO: How do rocks store CO2?

Dr Maxine Akhurst, principal geologist at the British Geological Survey (project lead for work package 3), gets some help from two rock stars to show how certain rocks are ideal for storing the greenhouse gas, carbon dioxide (CO2) deep below ground and ensuring it stays put.
