CO2 Geological Storage:Lesson Learned from In Salah (Algeria)
Iain Wright (CO2 Project Manager, BP Group Technology)
SBSTA Meeting Bonn May 20th 2006
Agenda
• CCS Benefits• CCS Challenges• The In Salah Project (Algeria)
– How In Salah is addressing the challenges
• Summary
Technology Options for Stabilization
The Stabilisation Wedge
Emission trajectory to achieve 500ppm
Emission trajectory BAU
1 GtC Slices of the Stabilisation Wedge
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
