Key QuestionsKey Questions
1. How do natural CO2 storage sites fail?
- Faults, lithology, caprock seal and groundwater regime.
2. What are the pathways of CO2 migration to the surface?
- Can we predict/prevent leakage in engineered sites?
3. How long does CO2 migration to the surface take?
- CO2 needs to be stored for 10,000 years.
4. Can leakage of CO2 be monitored and quantified?
- Which chemical tracers can be used.
- How effective are they at monitoring natural CO2 leakage?

- Cold water springs and geysers
driven by pressure of CO2.
- Gas is 95 - 99% CO2
- 0.5 - 3.5 % N2
- Trace noble gases.
- CO2 release from > 80ka.
- Where does this water and CO2
originate from?
- How is this CO2 being transported
to the surface?
