8 Storage

KEY MESSAGES

• Large-scale injection and geological storage of CO₂ has been safely performed in saline reservoirs for more than 15 years and in oil and gas reservoirs for decades.
• Current storage projects have developed and demonstrated comprehensive and thorough approaches to site management and monitoring.
• The majority of perceived risk in CCS projects is often associated with storage.
• It is important therefore that storage site selection and characterisation begin with the initial concept of a CCS project.
• More effort is needed to foster storage deployment globally, particularly in non-OECD countries. Interest is increasing in the role CO₂ EOR may have toward benefiting CCS.
