To implement carbon capture and storage (CCS) successfully, each underground repository will need careful appraisal based on its unique history and setting, according to a new study co-authored by researchers from the University of Bristol.

In 2000, one of the first commercial appraisals of CO2 geological storage was begun in Weyburn, Saskatchewan Province, Canada where approximately 3 megatonnes of CO2 are successfully sequestered every year. Scientists at Bristol have played a key research role in developing methods for monitoring the CO2 migration and storage in the reservoir.

In a paper published today in the Proceedings of the National Academy of Sciences, Dr James Verdon and colleagues from Bristol, the Geological Survey of Canada, the British Geological Survey and BP Alternative Energy compare results from the world’s three largest CCS projects.  Their study finds that not all sites are equal and successful implementation of CCS requires careful appraisal.
