Scope of Presentation
Why coal-to-liquid (CTL)?
What is Headwaters DCL technology
How to deal with high ash coals
Strategy for implementing CTL project
3
Indian Oil Balance
(BP Statistical Review)
Indian oil import projected to be 6 million BPD in 2030
CTL is the pragmatic alternative to imported crude

India ranks 4th in coal reserves
(mostly high ash coals)

CTL Technology Options
Direct Coal Liquefaction (DCL)
Coal + H2 Catalyst
linear + ring Hydrocarbons (CxH2x)
Coal/resid + H2 Catalyst linear + ring Hydrocarbons (CxH2x)
Indirect Coal Liquefaction (ICL)
1. Gasification: Coal + O2 + Steam
Syngas (H2 + CO)
Catalyst
2. FT Synthesis: H2 + CO
linear Hydrocarbons (CxH2x+2)

Approach in Processing High Ash Indian Coal
High ash coal:
– lower efficiency
– higher maintenance cost
Ash reduction prior to DCL
– Conventional coal washing
– Coal/oil agglomeration
– Solvent refined coal
Blending with low ash or no ash feedstock
– Gasification: petcoke (ash <30%)
– DCL: petroleum resid (ash < 12%)
(coal/oil co-processing)

Economic Analysis of ICL Project
(US mine mouth location)
Baler & O’Brien
(Mar/2007)
CAPEX
$85K per barrel/day capacity
OPEX
$15/bbl
Feedstock
$10 short ton
Total Liquid Yield 1.9 bbl/short ton
Distillate Price
122% of WTI
Equity
100%
No CO2 Capture
Breakeven crude oil price (WTI) = $48
To generate 12% after-tax IRR with no government incentive
Economics of CTL project depend on coal type, scale, & location
16
Overview of Worldwide CTL Activities
China: to startup first DCL plant; ICL-FT, MTG, MTO
under design/construction; government controlled pace
USA: mostly ICL with emerging interest in DCL
Indonesia: Active partnership with Korean & Japanese
companies
India: Oil India Limited Assam DCL project; government
coal block allocation RFP (both ICL and DCL proposals)
Australia: UCG & ICL-FT activities
Mongolia, Columbia, etc..
17
CTL Strategies/Key Points for Success
Coal reserve secured and accessible
Proven technology and adequate security package
Robust and experienced contractor
Deep pocket sponsors for completion &
performance risk
Optimal financing structure (low debt/equity ratio)
Sound risk allocation strategy
Use derivatives to control commodity risk
Positive government policy incentives
