  1. CO2 Sequestration Catherine Peters Princeton University Deep Carbon Cycle Workshop May 15-17, 2008 Carnegie Institution Geophysical Laboratory

  2. CO2 Capture and Storage (CCS) Fuels Processes Storage options INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC)

  3. Geological storage options INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC)

  4. CO2 phase diagram 100 Supercritical Fluid Critical Point Solid 800 m 10 depth Liquid Pressure [MPa] 1 Land Gas surface 0.1 -80 -60 -40 -20 0 20 40 60 Temperature [deg C] Deeper than 3000 m, CO2 Is denser than sea water. Density: 500 kg/m3 Data from Span and Wagner 1996

  5. Geographical relationship between sources and storage opportunities INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) Global distribution of large stationary sources of CO2 (Based on a compilation of publicly available information on global emission sources, IEA GHG 2002)

  6. 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 INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) 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).
