Risk assessment for CCS systems

Purpose

To develop and apply qualitative and quantitative risk assessment methodologies for long-term capture and geological storage of CO2, using modified risk assessment methodologies initially developed in the GEODISC program.

Summary

• Determine technical risk, social risk, regulatory risk, and environmental risk and use as a basis for comparison and selection of preferred alternatives.
• Evaluate risks arising from existing CO2 transport and injection operations including relevant overseas activities.
• Document leakage rates from natural analogues and compare with tolerance levels for humans, animals and vegetation.
• Demonstrate to stakeholders that geological storage is safe, secure and environmentally beneficial
• Participate in international meetings involving risk assessment technologies and research being applied to carbon capture and storage.
• Integrate ‘uncertainty’ into geological site characterization.
