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

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

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

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

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

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

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

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
