ADA-ES to Present at Pritchard Capital Energize 2007 Conference.

Management to Discuss Activities to Meet the Needs of Utilities for Mercury Control, and Provide Update on Vertical Integration into the Production of Activated Carbon

LITTLETON, Colo. -- ADA-ES, Inc. (NASDAQ:ADES) today announced that Michael D. Durham, Ph.D., President and Mark McKinnies, Senior Vice President and CFO, will present at the Pritchard Capital Partners Energize 2007 Conference on January 9, 2007 at the Omni Hotel in San Francisco, California.

ADA-ES' presentation will address ADA-ES' primary growth markets of Mercury Control and Section 45 Refined Coal Tax Credits. ADA-ES has been the market leader in developing mercury control technology for the power industry. The market for mercury control has been growing rapidly based upon new State regulations, which require up to 90% reductions in mercury emissions at existing power plants, and federal or state regulations that impose similar requirements on all new power plants. This heightened concern with mercury emissions has created a need for expanded capacity in the production of both equipment and activated carbon for this new and developing market. ADA-ES is committed to meeting the needs of the coal-fired power industry for these key components of mercury control technology.

In December of 2006, ADA-ES announced the termination of an exclusive market development agreement with Norit Americas, Inc. and ADA-ES' intention to vertically integrate into the production of activated carbon. The presentation will provide information on activities that ADA-ES is pursuing to secure its position and increase its earnings potential in this rapidly developing market. To date, ADA-ES has invested resources in multiple activities including: detailed market analysis, plant engineering, securing long-term access to lignite, the key raw material for producing activated carbon for this market, as well as partnering and acquisition discussions.

The presentation will be filed as a Current Report on Form 8-K with the U.S. Securities and Exchange Commission on January 9, 2006, and will also be available to any interested person via the Investor Information section of the Company's website at http://www.adaes.com.
