ADA-ES Refined Coal 
process:
Adds proprietary chemicals on
Western Coal
For Cyclone boilers
Burns cleaner and more
efficiently

-29-
Status:  Cyclean Refined Coal
Simple process designed for rapid deployment
Demonstrated at three full-scale plants
achieving emission reduction levels that can
qualify for the tax credit
Patents on key components of technology;
recently applied for new patents
Marketing effort underway

-30-
Cyclean Business Model
Established a JV, Clean Coal Solutions LLC (CCS), with
an affiliate of NexGen Resources Corporation
NexGen to pay ADA-ES $5mm for 50% of CCS upon tax
qualification
Expect CCS to have chemical revenue of $3-4/ton
The $6/ton tax credit to be monetized into $4.80/ton
revenue (may share tax credit with customer)
Target market: Cyclone boilers burning PRB coal
60 million tons per year total market
20 million tons per year currently require mercury control

-31-
Remaining Challenges for Refined Coal
Recent PRB
Coal Prices
Clarification of “50% Market Value”
requirement
2006 price spikes created unexpected volatility
Congressional clarification required
Bill currently in joint House/Senate committee

Summary
ADA-ES has been instrumental in creating a new mercury
control market
Existing rules: estimated 150 ACI systems, 400 mm lbs/yr AC
Pending Federal Rule: estimated 600-700 ACI systems, 1 B
lbs/yr AC
Already a leading provider of engineering services and
equipment for the mercury control market
Building new AC plants for this market
Operating permits for 6 production lines expected Q1-2 2008
Well positioned to respond to AC demand by Federal rule
Progress with Refined Coal; substantial market opportunity
Developing control technology for Greenhouse gases
The next big opportunity in Emission Control
Strong financial position and growing revenue base
