California Energy Commission Sacramento 9/30 to 10/ Stationary CO 2 Sources Sequestration Data and Impacts on Total Emissions Coal-Fired Power Plant and Gasification Facility

West Coast Regional Carbon Sequestration Project Kick-Off Sacramento 9/30 to 10/ What’s a “Nexant”  Formed on January 1, 2000  Core group from units of Bechtel Group, Inc.,  Ten permanent offices & projects around the world  Fulltime staff of 300  Portfolio of 75 projects in 30 countries Advanced Power Generation, Climate Change, CO2 Sequestration, Fuel Cells, Hydrogen (production, delivery, and vehicles), Solar, Biomass, Co-Production Clean Fuels Plant, Other Energy Stuff.

West Coast Regional Carbon Sequestration Project Kick-Off Sacramento 9/30 to 10/ Site and Industry Data Primary Emission Sources – Power, cement, chemical & refinery, mining, paper, and other large, technically sophisticated plants Secondary Sources – Combustors such as prisons, hospitals, military bases, universities Source criteria will be established as data is reviewed

West Coast Regional Carbon Sequestration Project Kick-Off Sacramento 9/30 to 10/ Data Sources Existing Federal reporting systems; US DOE, EPA Existing State reporting systems Telephone, s and other communications to collect data Visits and whipping posts

West Coast Regional Carbon Sequestration Project Kick-Off Sacramento 9/30 to 10/ Data Types Carbon inputs and outputs Other emissions, solid and liquid wastes Process descriptions Emission stream conditions, temperature, pressure, constituents Site data – location, transport access, available space, surrounding features As much cost and economics as will be provided

West Coast Regional Carbon Sequestration Project Kick-Off Sacramento 9/30 to 10/ Data Types (Maybe) Existing pollutant controls and waste disposal Existing and developing control technologies database And Maybe, Site process performance Major equipment types, age, and performance

West Coast Regional Carbon Sequestration Project Kick-Off Sacramento 9/30 to 10/ Data Structure To be determined – I think I know what is needed for decision-making from technical, process and environmental side. However, There is an early need to coordinate and define all our data structure to fit the databases, and assessment models

West Coast Regional Carbon Sequestration Project Kick-Off Sacramento 9/30 to 10/ Database and Assessment Objectives Definition of current conditions Pilot plant locations and logistics Other R&D opportunities i.e. CO 2 capture, multi-pollutant technologies, terrestrial opportunities too Early commercial opportunities Longer range CO 2 reduction and sequestration options

West Coast Regional Carbon Sequestration Project Kick-Off Sacramento 9/30 to 10/ Other Considerations and Grist for the Mill Global nature of the problem, the research, and the opportunities Timing for planning, R&D, education, policy and actions Practical technologies not yet available Retrofit of existing sources very unlikely Future plants will need to have zero emission designed and built-in

West Coast Regional Carbon Sequestration Project Kick-Off Sacramento 9/30 to 10/ More Grist Geological sequestration needs to be ready, tested, accepted, and cost efficient Oil and gas deposits a near-term possibility, deep aquifers and coal seams later, mineral carbonation much later The next 16 or so months will only skim the surface of what needs to be done
