McKinnies, Senior VP & CFO 303-734-1727 www.adaes.com or Investor Relations Counsel The Equity Group Inc. www.theequitygroup.com Melissa Dixon, 212-836-9613 MDixon@equityny.com Linda Latman, 212-836-9609 LLatman@equityny.com ADA-ES, Inc. (NASDAQ: ADES) today announced that it was notified by the Department of Energy that it had been selected to develop a technology that will capture carbon dioxide from coal-fired power plants. ADA-ES will be the prime contractor in what is expected to be a several million dollar project with the DOE's National Energy Technology Laboratory and several industry participants. Several major power producers interested in supporting the development of the technology have provided letters of commitment to contribute $1.2 million of the project

funding. These participants include AEP, Luminant, Southern Company, and Xcel Energy. In addition, the Electric Power Research Institute has agreed to support the project. Final scope of work and terms are to be worked out with DOE on the contract over the next two months.

The technology is being designed to provide a means of reducing the emissions of greenhouse gases from coal-fired boilers. In the United States, alone, there are 1,100 coal-fired power plants with a total capacity of 320 GWs of electricity and, as a group represent the single largest source of carbon dioxide emissions from human activity. Regulations to limit carbon emissions in the future are being discussed at the International, Federal, Regional, and State levels.

ADA-ES will be developing emission reduction technology based around the use of solid sorbents. Most competing technologies use liquid solvents such as ammonia or amines to accomplish this task.

Dr. Michael Durham, President of ADA-ES, Inc., commented, "We are pleased that the Department of Energy selected our Company to perform this needed work. The DOE and power producers have confidence in our reputation and proven abilities to develop innovative solutions for reducing emissions and meeting environmental standards and in going the next step in providing the technology commercially. The political momentum for enacting carbon dioxide regulations at the state and national levels is rapidly growing, and technologies need to be developed that are going to meet the requirements in a cost-effective way."

The project is expected to start by October 1, 2008 and last for three years. During that time, ADA-ES will be managing a team of technical experts and will be performing testing at several of the power producers on the team.
