IL Clean Coal Review Board October 16, 2000
The Illinois Clean Coal Review Board announced
today that ClearStack Combustion Corporation will receive a $1 million grant to demonstrate its
environmental control break-through technique called the Ashworth Combustor TM. This innovative
technique reduces the three major air pollutants (SO2, NOX and particulate) from coal combustion
using a simple three-stage combustion system. Tests have shown that under deeply reducing
conditions, with lime or limestone addition that coal sulfur (as CaS) can be captured in a non-leaching
slag eutectic. Low NOx emission levels can also be achieved (< 0.15lb NOX /106 Btu).

"ClearStack technology
could lead to the opening of one or more existing or new mines. It's one of the more promising
technologies right now," said Taylor Pensoneau, President of the Illinois Coal Association and a
member of the Illinois Clean Coal Review Board.

Rod Blagojevich, Governor of Illinois, during a radio broadcast, cited ClearStack
as the kind of state-assisted research project that could help the beleaguered Illinois coal industry,
which has dwindled as power generators have turned to cleaner burning low-sulfur coal to meet federal
clean-air emissions standards. “There is a company here in the Springfield area called ClearStack
Combustion…,” Blagojevich said. “We don’t need to do any more research and development and waste
taxpayer dollars on it. The technology already exists.”

A new means of on-site fuel generation for potato processing
facilities using recovered potato waste solids has been discovered. The breakthrough could help
companies achieve energy savings while at the same time operate in a more environmentally friendly
manner. This Water & Oil Technologies-patented fuel feedstock process, combined with the use of the
Ashworth Combustor, will create the desired syngas while meeting environmental requirements on both
sides of the Atlantic.

This project demonstrates the commercial viability of
ClearStack Combustion Corporation’s Ashworth Combustor TM. This novel combustion technique uses
three stages of combustion, which reduces SO2, NOx, and particulate. The host site for the first retrofit
was the Illinois Department of Human Service’s Lincoln Development Center in Lincoln, Illinois. Phase
two of the project will be carried out with assistance from Ameren AEG, Promecon, and Sargent and
Lundy. This project will determine whether or not, AEG’s Hutsonville Boiler #6 can be retrofitted with
the Ashworth Combustor System.
