Evergreen Energy Inc. and TXU Sign Letter of Intent to Test Innovative Coal Technology

Cleaner Coal Technology Designed to Increase Efficiency and Reduce CO2 and Other Emissions From Coal-Fueled Power Plants 


DENVER, Jan. 31  /PRNewswire-FirstCall/ -- Evergreen Energy Inc. (NYSE:EEE) and TXU Generation Development Company LLC, a subsidiary of TXU Corp., have signed a letter of intent for detailed engineering, design integration and tests of the K-Direct coal refining process.

Should the results from the engineering, design and testing be successful, the companies could enter into one or more definitive agreements for the construction of K-Direct coal refineries at new or existing TXU power plants. The companies have agreed not to disclose more specific terms of the transaction until they sign a definitive agreement.

K-Fuel(R) refined coal results from an advanced process that is designed to improve the heating value and lower the emissions per kilowatt-hour produced from sub-bituminous and lignite coals.  The coal could be refined at the mine or at K-Direct coal refineries situated alongside existing or new coal-fueled power plants.

The two companies are now evaluating process compatibility, design options, project costs, schedules and the detailed results from tests of K-Fuel(R) refined coal processed from Texas lignite at Evergreen's Gillette, Wyoming coal refinery.

"TXU is setting a new environmental benchmark, raising the standard for both existing and planned coal-fueled plants," said Mark Sexton, chairman and CEO of Evergreen.  "We are pleased that K-Direct coal refineries are part of the trend toward cleaner coal solutions.  While many clean energy solutions for coal-fueled power plants remain commercially unproven and are several years away, we believe that K-Direct's process could work well with TXU's existing and planned coal plants.  TXU's efforts to lead the nation by using coal for power generation in an environmentally and economically responsible manner are commendable," added Sexton.

"This is another example of our ongoing efforts to investigate, develop and commercialize technologies to reduce emissions," said Mike Childers, CEO of TXU Generation Development.  "Our work with Evergreen Energy in evaluating the K-Direct coal refining process is another important addition to this effort."

The K-Direct coal refineries are designed to better and more efficiently reduce emissions, lower fuel consumption, and capture efficiencies of scale by using shared or common facilities.

Evergreen & K-Direct Background

Using a proprietary process involving steam and pressure, Evergreen Energy refines a wide range of sub-bituminous and lignite coals into K-Fuel(R), a more efficient coal that provides more energy with lower emissions and improves the performance of post-combustion emission control technologies.

Under the K-Fuel(R) process, a K-Direct refinery located next to an existing power generating station uses the station's secondary steam as a power source and returns large amounts of water produced by the K-Fuel(R) refinement process.

For example, when compared to raw coal from Wyoming's Powder River Basin K-Fuel(R) has approximately 30 percent more Btu's per pound with an approximate 70 percent reduction in mercury, and upon combustion significant reductions in sulfur dioxide, nitrous oxides and carbon dioxide on a "per kilowatt-hour generated" basis.  Results will vary depending on the type and source of the coal.

                                FACT SHEET

  *  Evergreen Energy's K-Fuel(R) coal refining process is a proven
     commercial technology that is available today (NOW-Gen) to improve the
     energy and environmental performance of coals like lignite.
  *  Evergreen has built the world's first coal refinery in Gillette,
     Wyoming that uses the K-Fuel(R) process and has already produced
     thousands of tons of refined coal that has performed well in both
     laboratory tests and full-scale deployment in large industrial,
     commercial and utility plant boilers. Tests showed reductions in sulfur
     dioxide, nitrogen oxide, mercury and carbon dioxide while improving the
     parent coal by as much as 30 percent in terms of heat content
     improvement and water elimination.
  *  Pre-combustion refinement of coal removes a significant portion of the
     pollutants before they are produced, reducing the need to capture and
     dispose of them in post-combustion.

  We Must Pursue The Best And Most Immediately Available Technologies To
      Improve The Environmental And Energy Characteristics Of Coal.

  *  Evergreen Energy's patented "refined" coal has more energy per pound
     than raw coals. Therefore, it is more efficient and produces fewer
     emissions per kilowatt-hour generated.
  *  Evergreen Energy's K-Fuel(R) and K-Direct commercial process is ready
     today, not years down the road.
  *  Evergreen Energy's process provides an immediate environmental and
     efficiency improvement to utilities, industrial customers and
     communities.

       Efficiency and Environmental Improvements From Refined Coal

  *  Refined K-Fuel(R) handles and transports equal to or better than the
     parent coal it is made from.
  *  Depending on the source of the raw coal, refined K-Fuel(R) burns with
     lower mercury, sulfur dioxide, nitrogen oxides and carbon dioxide
     emissions than raw, lignite or sub-bituminous coal when calculated on a
     unit energy basis.
  *  The use of K-Fuel(R) produced either at the mouth of the mine and
     transported or adjacent to the host coal-fueled power plant in a K-
     Direct facility is, in most cases, a superior, lower-cost compliance
     alternative to installing expensive back-end emissions controls that
     are costly to operate and contribute substantially to the host coal
     plant's parasitic load.
