Stationary CO2 Sources

1
Coal-Fired Power Plant and Gasification Facility

• Stationary CO2 Sources
• Sequestration Data and Impacts on Total Emissions

2
Whats 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.

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

4
Data Sources

• Existing Federal reporting systems US DOE, EPA
• Existing State reporting systems
• Telephone, emails and other communications to
  collect data
• Visits and whipping posts

5
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

6
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

7
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

8
Database and Assessment Objectives

• Definition of current conditions
• Pilot plant locations and logistics
• Other RD opportunities i.e. CO2 capture,
  multi-pollutant technologies, terrestrial
  opportunities too
• Early commercial opportunities
• Longer range CO2 reduction and sequestration
  options

9
Other Considerations and Grist for the Mill

• Global nature of the problem, the research, and
  the opportunities
• Timing for planning, RD, 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

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
