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.
