INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Dear user, Thank you for the outreach you are undertaking for the IPCC Special Report on Carbon dioxide Capture and Storage! This note contains some instructions on how this standard presentation can be used. Please note that the Summary for Policymakers (SPM) is agreed government text and the official point of view of the IPCC. The slides in this presentation reflect this carefully established scientific consensus. While presenting the results of the IPCC Special Report, please stay close to the contents of the report and indicate clearly when you are giving your personal rather than the IPCC view. The presentation is very long and repetitive. Depending on your audience, please pick and choose from the slides, and modify them where you deem it appropriate, keeping in mind the agreed SPM text. The notes under the slides contain language from the SPM and the Technical Summary and other explanations for your reference. With kind regards, Bert Metz and Ogunlade Davidson, co-chairs WGIII

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) CO 2 capture and storage system Fuels Processes Storage options

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) How could CCS play a role in mitigating climate change? Part of a portfolio of mitigation options Reduce overall mitigation costs by incresing flexibility in achieving greenhouse gas emission reductions Application in developing countries important Energy requirements point of attention

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Energy requirements Additional energy use of % (for same output) Capture efficiency: % Net CO 2 reduction: % Assuming safe storage

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Maturity of CCS technology Research phase means that the basic science is understood, but the technology is currently in the stage of conceptual design or testing at the laboratory or bench scale, and has not been demonstrated in a pilot plant. Demonstration phase means that the technology has been built and operated at the scale of a pilot plant, but further development is required before the technology is ready for the design and construction of a full-scale system. Economically feasible under specific conditions means that the technology is well understood and used in selected commercial applications, such as in case of a favourable tax regime or a niche market, processing at least 0.1 MtCO 2 /yr, with few (less than 5) replications of the technology. Mature market means that the technology is now in operation with multiple replications of the commercial-scale technology worldwide.

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Geographical relationship between sources and storage opportunities Global distribution of large stationary sources of CO 2 (Based on a compilation of publicly available information on global emission sources, IEA GHG 2002)

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Geographical relationship between sources and storage opportunities Storage prospectivity Highly prospective sedimentary basins Prospective sedimentary basins Non-prospective sedimentary basins, metamorphic and igneous rock Data quality and availability vary among regions Prospective areas in sedimentary basins where suitable saline formations, oil or gas fields, or coal beds may be found. Locations for storage in coal beds are only partly included. Prospectivity is a qualitative assessment of the likelihood that a suitable storage location is present in a given area based on the available information. This figure should be taken as a guide only, because it is based on partial data, the quality of which may vary from region to region, and which may change over time and with new information (Courtesy of Geoscience Australia).

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Costs Two ways of expressing costs: Additional electricity costs –Energy policymaking community CO 2 avoidance costs –Climate policymaking community Different outcomes: US$/kWh 20* US$/tCO 2 avoided (with EOR: 0*– 240 US$/tCO 2 avoided) * low-end: capture-ready, low transport cost, revenues from storage: 360 MtCO 2 /yr

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) CCS component costs CCS componentCost range Capture from a power plant US$/tCO 2 net captured Capture from gas processing or ammonia production US$/tCO 2 net captured Capture from other industrial sources US$/tCO 2 net captured Transportation US$/tCO 2 transported per 250km Geological storage US$/tCO 2 injected Ocean storage US$/tCO 2 injected Mineral carbonation US$/tCO 2 net mineralized

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Economic potential

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Economic potential Cost reduction of climate change stabilisation: 30% or more Most scenario studies: role of CCS increases over the course of the century Substantial application above CO 2 price of US$/tCO 2 15 to 55% of the cumulative mitigation effort worldwide until ,200 GtCO 2 cumulatively up to 2100, depending on the baseline scenario, stabilisation level ( ppmv), cost assumptions

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Storage potential Geological storage: likely at least about 2,000 GtCO 2 in geological formations "Likely" is a probability between 66 and 90%. Ocean storage: on the order of thousands of GtCO 2, depending on environmental constraints Mineral carbonation: can currently not be determined Industrial uses: Not much net reduction of CO 2 emissions

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Technical and economic potential “It is likely that the technical potential for geological storage is sufficient to cover the high end of the economic potential range, but for specific regions, this may not be true.” "Likely" is a probability between 66 and 90%.

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Health, safety, environment risks In general: lack of real data, so comparison with current operations CO 2 pipelines: similar to or lower than those posed by hydrocarbon pipelines Geological storage: –appropriate site selection, a monitoring program to detect problems, a regulatory system, remediation methods to stop or control CO 2 releases if they arise: –comparable to risks of current activities (natural gas storage, EOR, disposal of acid gas)

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Health, safety, environment risks: potential leakage from geological reservoirs and remediation

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Health, safety, environment risks: trapping mechanisms for geological storage

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Health, safety, environment risks Ocean storage: –pH change –Mortality of ocean organisms –Ecosystem consequences –Chronic effects unknown Mineral carbonation: –Mining and disposal of resulting products –Some of it may be re-used

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Impacts –pH change –Mortality of ocean organisms –Ecosystem consequences –Chronic effects unknown Ocean Storage Change of bacteria, nanobenthos and meiobenthos abundace after exposure to 20,000 and 5,000 ppm for hrs during experiments carried out at 2000 m depth in NW Pacific 100% 80% 60% 40% 20% 0% -20% -40% -60% -80% -100% <10  m10-30  m MeibenthosNanobenthosBacteria Change population 20,000 ppm 5000 ppm

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Will leakage compromise CCS as a climate change mitigation option? Fraction retained in appropriately selected and managed geological reservoirs is –very likely to exceed 99% over 100 years, and –is likely to exceed 99% over 1,000 years. "Likely" is a probability between 66 and 90%, "very likely" of 90 to 99% Release of CO 2 from ocean storage would be gradual over hundreds of years Sufficient?

INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) What are the legal and regulatory issues for implementing CO 2 storage? Onshore: national regulation –Few legal or regulatory frameworks for long-term CO 2 storage liabilities Offshore: international treaties –OSPAR (regional), London Convention –Ocean storage and sub-seabed geological storage –Unclear whether or under what conditions CO 2 injection is compatible with international law
