"Carbon dioxide pumped into old oil wells could react with salt water and erode ‘host rocks’ and cement, researchers find".

"Pumping carbon dioxide underground is critical to meeting an international goal of holding global warming “well below 2C”.

Climate modellers struggle to make emissions budgets add up without widespread use of carbon capture and storage in the medium term.

But researchers from Penn State University have found multiple ways CO2 can escape from geological reservoirs, highlighting a risk the process could fail."
