CCS 2006: Key Challenges

1. Reducing the Costs– Mainly Capture, Capital Cost and Efficiency– Target: $20-30/t CO2

2. Is it Legal?• Long-term Storage Integrity• Legal & Regulatory Frameworks

3. Can you get Paid? • Policy Frameworks• Market Eligibility (CDM,ETS)

4. Public Acceptance

• Only the separated (yellow) CO2 will be stored –the combustion CO2 (blue) will be vented

In Salah CO2 Storage

• Industrial Scale Demonstration of CO2 Geological Storage (Conventional Capture)

• Started Storage in August 2004• 1mmtpa CO2 Stored (17mm tonnes lifetime)• $100mm Incremental Cost ($6/tCO2)

– No Commercial Benefit

• Test-bed for CO2 Monitoring Technologies

–In Salah CO2 Assurance• R&D (CSLF $30 million)

Joint Industry R&D Project

Objectives (2004-09)

1. Provide assurance that secure geological storage of CO2 can be cost-effectively verified and that long-term assurance can be provided by short-term monitoring.

2. Demonstrate to stakeholders that industrial-scale geological storage of CO2 is a viable GHG mitigation option.

3. Set precedents for the regulation and verification of the geological storage of CO2, allowing eligibility for GHG credits

Why Monitoring?

• Need more cost-effective tools to demonstrate long-term storage integrity

• Oil & Gas Industry already has most of the tools required, but has never had a commercial reason to develop them

• Mother Nature made all geological formations different– Monitoring technology that works in one location may not

work in another– Need to develop a pool of knowledge – Need to set standards for site certification
