420,000 year assessment of fault leakage rates shows geological carbon storage is secure.

Carbon capture and storage (CCS) technology is routinely cited as a cost effective tool for climate change mitigation. CCS can directly reduce industrial CO emissions and is essential for the retention of CO extracted from the atmosphere. To be effective as a climate change mitigation tool, CO must be securely retained for 10,000 years (10 ka) with a leakage rate of below 0.
