PEMRGPURDUE ENERGY MODELING RESEARCH GROUPS
Phase I Background• Project began in Phase I by developing a
compendium of information about Clean Coal Technologies (CCT) topics along two dimensions– Technologies of CCT– Indiana environment for CCT
• Then investigated a series of scenarios about alternative technologies, and impacts of CO2 capture in new construction and/or some retrofit
3
PEMRGPURDUE ENERGY MODELING RESEARCH GROUPS
Phase II Vision• Investigate the feasibility of one or more
Synfuel Parks in the state using gasified Indiana coal to produce– Any or all of Fischer-Tropsch (FT) Diesel, Jet
Fuel, Electricity, Syngas, and related chemicals
• Having conforming air & water emissions and expectation of sequestering CO2

Single Site vs. Distributed• Originally thinking about all park activity at
single sites• Recently decided to include Distributed
Synfuel Parks with production facilities at multiple locations– Demo Case: SW Indiana coal shipped to the
existing Wabash spare gasifier, then sending syngas to new FT plant, feeding the Mt. Vernon refinery to do diesel production

PEMRGPURDUE ENERGY MODELING RESEARCH GROUPS
Synfuel Park Design Opt• Maximize the economic returns over
– Sites– Coal supplies– Numbers, sizes & types of different facilities– Markets for different products (including
competitive risks from crude oil & tar sands)– Transportation & infrastructure at all stages– Management of CO2 & other environmental
concerns– Government incentives & regulation
8
PEMRGPURDUE ENERGY MODELING RESEARCH GROUPS
Activity to Date• Funding only available quite recently
– Progress has been delayed• Focused so far on data collection about
– Technologies for the various components– Cost for technologies & infrastructure to
support them– Potential for CO2 sequestration– Standards for site selection

Technologies & Costs1. Syngas production Low temperature reactor + catalyst
Theoretical work has been there a long time. Great Point Energy has worked on this. It is said to be able to bring down cost but we don’t yet know by how much
High temperature gasification reactorThis is a proven technology and we have collected cost data
Hydrogen gasificationTechnology and cost are unproven

Technologies & Costs2. FT Liquification• There is a separate CCTR study and we will
coordinate• We have collected lot of technology and cost
data. There are various processes using basically the same principal. Some are commercial while others are still under test
• Catalyst used seems to be an important factor in determining cost (Syntroleum claims a super one)
• Choice of FT technologies related to product mix desired
11
PEMRGPURDUE ENERGY MODELING RESEARCH GROUPS
Technologies & Costs3. Power production• Power production benefits from steam with high
temperature gasification, but less so with the lower temperature technologies
4. Sites• Some developers will already have preferred sites• In addition, we have identified site criteria to screen
possibilities: power grid, water, rail, coal mines, sequestration, gas pipelines, highway, land use
12
PEMRGPURDUE ENERGY MODELING RESEARCH GROUPS
CO2 Sequestration • CO2 sequestration – May be a key to the
future for clean coal projects
• Have been collecting cost & potential data of CO2 capture, pipeline, injection etc., and working with IGS and Illinois Geology Survey for likely sequestration sites (EOR, CBM, and aquifer)
13
PEMRGPURDUE ENERGY MODELING RESEARCH GROUPS
CO2 Sequestration - Magnitudes• Estimated potential
– Western Indiana (EOR+CBM) = 0.234 Gton (361 Gscf)– Eastern Illinois (EOR+CBM) = 2.480 Gton (3903 Gscf)– Eastern Indiana (saline) = 80.7 Gton *– Illinois Basin (saline) = 34-39 Gton *
• CO2 production– Indiana coal-fired power = 0.092 Gton / year
• Natural gas consumption comparison– Indiana total = 526 Gscf / year
* different studies with conflicting assumptions

Related Student: Risk Analysis• Whether a syngas plant survives depends on the
movement of natural gas prices• CTL the same relative to world crude prices and
competition from oil sands in Canada • Student working on a gaming model that takes
into consideration the gaming behavior of OPEC & oil sands vs. CTL & syngas
• The results (to be presented at a DOE conference) show CTL may have a big role

PEMRGPURDUE ENERGY MODELING RESEARCH GROUPS
Demo Case of Distributed Park• Wabash has a spare gasifier ready for use• Mount Vernon refinery has a capacity of 23,000
bpd (with almost 25% extra capacity)• There is a gas pipeline between Terry Haute and
Evansville• Questions are: Can the pipeline be used for
shipping syngas south? Would it be better to add the FT facilities near the Wabash gasifier and ship liquids?

PEMRGPURDUE ENERGY MODELING RESEARCH GROUPS
Main Thrusts of Future Work• Reduce sites to a small list• Select technologies to include and continue
to collect data on performance & cost• Link with data on infrastructures & analyses
of market risks• Structure an optimization model for Synfuel
Park design• Refine & apply the model under numerous
scenarios to produce project findings
