Miocic, J.; Gilfillan, S.; Frank, N.; Schroeder-Ritzrau, A.; Burnside, N.; Haszeldine, S. (2019): 420,000 year assessment of fault leakage rates shows geological carbon storage is secure. In: Scientific reports 9 (1), S. 769. DOI: 10.1038/s41598-018-36974-0.

"Carbon capture and storage (CCS) technology is routinely cited as a cost effective tool for climate change mitigation. CCS can directly reduce industrial CO2 emissions and is essential for the retention of CO2 extracted from the atmosphere. To be effective as a climate change mitigation tool, CO2 must be securely retained for 10,000 years (10 ka) with a leakage rate of below 0.01% per year of the total amount of CO2 injected. Migration of CO2 back to the atmosphere via leakage through geological faults is a potential high impact risk to CO2 storage integrity."
