  4. Excerpt from OilGas 24 Scandinavian Oil and Gas Magazine Statoil, Shell assemble carbon frontrunners courtesy Statoil A mobile carbon-scrubbing construction will be tested in May at the Shell-Statoil carbon-dioxide project at Risavika, just outside Stavanger, it was learned Tuesday. Canadian supplier Cansolv is one of three suppliers to the full-scale Halten CO2 project at Tjeldbergodden central Norway. Mitsubishi Heavy Industries and Fluor are the other carbon sequestration companies employed in the tests. The companies are vying for a contract to stop 2.5 million tonnes a year from flowing into the atmosphere at a future 850 Megawatt gas-plant on the Tjeldbergodden site…. … Cansolv is dwarfed by the two industrial giants, but “sits on solid knowledge on the separating of carbon from natural gas”, although the plan is to separate 85 percent of the C02 from the power plant’s exhaust passages. • http://www.oilgas24.com/bm/Gas/statoil-shell-assemble-carbon-frontrunners.shtml

  5. Technology Focus • Core platform process is CANSOLV SO2 Scrubbing – Selective amine scrubbing in an oxidative environment • The Cansolv breakthrough in operating costs: • low salt formation • low amine degradation • low heat of regeneration • R&D Focus in 2000-2007 on developing high performance solvents for NOx, Hg & CO2 absorption • Commercialization Focus in 2005-2007: optimizing processes: • CO2 - SO2

  6. UN International Panel on Climate Change • Changes in Global Temperature and Climate are due to anthropogenic sources of green house gas - Working Group 1 - Feb. 2007 • Changes in Global climate have non-uniform local impact • on ecosystems and area weather, climate and populations • - Working Group 2 - April, 2007 IPCC Website - http://www.ipcc.ch/

  7. Kyoto Protocol • Entered into force February, 2005 • Mandates a 5.2% reduction in GHG emissions in • comparison to 1990 levels between 2005 and 2010 • inclusive of economic growth. • Factoring in economic growth, Kyoto represents a • 29% reduction

  8. World Energy Demand World Energy Demand is Expected to double by 2030. Oil and gas consumption Expected to increase by 60% by 2030 Source - IEA Website - http://www.iea.org/

  9. The Power Industry is the World’s Greatest Producer of CO2 • Greatest potential for CO2 Capture is from power plants • Current EOR CO2 injected is 50 MMtpy • Required CO2 capture by 2030 is 7,000 MMtpy

  10. Geological Storage Reservoirs Have the Greatest Capacity for Captured CO2 For Example: • In North America, the top 500 sources emit 3.3 Gt/yr • 3.1 Gt CO2/yr can be stored in formations within 150 km of each source Total storage capacity Is much greater Source; IEAGreenhouse

  11. History of PCOR* in the US IllustratesHow a CCS Program can be Executed The United States DOE established the National Energy Technology Laboratory (NETL) to manage seven partnerships • Phase 1 studies identified sources and sinks 2003 - 2005 • Phase 2 studies executed research programs to • study key sequestration strategies - 2005 to present *Plains CO2 Reduction Partnership
