Abstract:

Carbon dioxide (CO₂) capture at the site of production and storage at deep underground sites is currently being investigated as a way of reducing emissions to the atmosphere. There is potential underground storage capacity for between 1300 and 11 000 Gt of CO₂, but the risks and impacts on ecosystems of possible leakage from these storage areas and the associated transport systems need to be understood. While the risks in transport, e.g. pipeline failure, are reasonably well known, the experience of deep storage is relatively short and risks are estimated on the basis ...
