Outline

• Fischer-Tropsch CTL
• Spatial data development
• Sequestration inquiry tool development
• http//www.WVCarb.org
• Site Rating Model development

Fischer-Tropsch CTL

• Aka, coal liquefaction, coal to liquids, CTL
  synfuels, etc. Two primary methods

ONE

4
Data Development

• Infrastructure Data
• Sequestration Data
• Source WVGES
• Sequestration potential per unit area
• Will be implemented into NatCarb.org

5
CTL Infrastructure Requirements

• Standard stuff electricity, roads, coal supply,
  etc.
• Water, water, water! to move!
• Carbon sequestration proximity. to move!
• Existing pipelines.

Sequestration Per Unit Area

• Source data shapefile polygons blobs with a
  number attribute of capacity

• At a specific point
• How much carbon dioxide can be sequestered
  within X distance?
• Problems!

9
Sequestration Per Unit Area

• To develop this tool, we must undergo raster
  conversion.
• Total sequestration (metric tons) must be
  converted to
• Metric tons PER 90m pixel
• S per 90m sequestration/(area sq. m/8100)
• 90 meter pixels result in values within 2 of
  actual.

10
Tool Development

• Data development has been driven by the need to
  answer this question
• How much carbon can we put in the ground within
  10 miles of THIS point?

Ratings Development

• Goal To rate (1-100) sites in West Virginia for
  their suitability to host a CTL facility.
• Model will be scripted, repeatable, and variables
  can vary as necessary.
• Model is constructed around weighted distance
  decay functions.
• Carbon sequestration decays by distance, volume
  and economic value.
• Infrastructure decays by distance and cost.

14
Ratings Development

• Rating sequestration neighborhoods

• Option 1 given a need for a predetermined
  amount of sequestration, what size neighborhood
  do we need?
• Use radius in a distance decay function
• Difficult to calculate
• Statistically over-values sequestration
  variables

• Option 2 given a need for a predetermined
  amount of sequestration (10 years of CTL
  production), and several neighborhood sizes (1,
  5, 10, 20 miles), which sites offer the MOST
  sequestration in the SMALLEST neighborhood?

Radius ?
R 1, 5, 10, 20 miles Q ?

Ratings Development

• Sequestration
• can be retrieved with an existing GIS
  function, neighborhood analysis, focal
  statistics. Calculates a sum within a
  neighborhood.
• Somewhat resource intensive to calculate

Future Work

• Inclusion of a click and rate tool for
  potential CTL sites
• Model refinement
• New research into distance metrics for
  sequestration
• New energy economy data clearinghouse
