FOR IMMEDIATE RELEASE

ADA-ES REPORTS THIRD QUARTER RESULTS AND HIGHLIGHTS RECENT

CORPORATE DEVELOPMENTS

Littleton, CO – November 6, 2008 – ADA-ES, Inc. (NASDAQ:ADES) today announced financial results for the third quarter ended September 30, 2008. See attached tables.

For the third quarter, total revenues were $5.0 million compared to $5.6 million in the same period of last year, with the decline primarily due to reduced revenues from DOE and industry supported mercury programs ($1.0 million versus $2.1 million). The Company expects funding for mercury related projects to continue to decline, but anticipates funding for CO₂ technology to commence in late 2008 and continue to grow. Gross margin was 33%, essentially flat with last year’s third quarter. ADA reported an operating loss of $256,000 compared to operating income of $34,000 in the third quarter of last year and a net loss of $167,000, or $0.03 per diluted share, compared to net income of $215,000, or $0.04 per diluted share, in the 2007 third quarter.

Dr. Michael D. Durham, President and CEO of ADA-ES commented, “Thus far in 2008, ADA-ES has signed contracts or received orders to proceed with 6 Activated Carbon Injection (“ACI”) systems for delivery in 2008 through 2009, bringing the total number of ADA ACI systems installed or currently in process to 35. Additionally, we recently received positive indications from customers on 5 systems that must be installed in 2009. We experienced a significant increase in bid and proposal activity for ACI systems in the third quarter; since August we have bid or are currently bidding on 16 ACI systems and expect to bid on between 30 and 40 ACI systems through 2009 based upon current regulations. Many of the new inquiries for ACI systems are stemming from Canada, which recently imposed new mercury regulation compliance dates.”

Dr. Durham continued, “All of the ACI systems being installed will require ongoing supply of activated carbon (“AC”) beginning in 2009 or 2010. ADA continued to hit key milestones during the third quarter, especially related to ADA’s position as a long-term supplier of AC:

• ADA formed a 50/50 joint venture with Energy Capital Partners (ECP) designed to supply the equity needed for the development of the largest AC production facility in North America. Highlights of our agreements include:

• ECP will purchase 3.6 million Convertible Preferred shares. The first 1.8 million shares were priced above market at $9.37 per share with the second 1.8 million shares to be priced at a later date.

• Allows the Company to sell up to an additional one million ADA shares to fund equity contributions to the AC project.

• Provides a mechanism for ECP to contribute additional capital to finance plant construction if ADA experiences a funding shortfall.

• We began construction of the plant in August through a contract with BE&K Construction Company for the engineering, procurement, and construction work with confirmed pricing, schedule, and performance.

• ADA completed a private placement of 909,000 shares of our common stock to 3 institutional investors, raising a net of approximating $6.4 million.

• We signed a $125 million six-year contract to supply treated AC to Luminant, a Dallas-based, competitive power-generation business.

“So far, we have been awarded $160 million in contracts for AC and have responded to $500 million in additional requests for proposals. With these contracts in place and more awards expected, we remain confident that we will secure the debt financing required to complete the AC production facility.”

The Company also reports progress on its two other clean coal technology business areas:

• In The Emergency Economic Stabilization Act of 2008, Congress included language on Section 45 that provides a one-year extension of the deadline for equipment installation and eliminated the increase in “market value” requirement for refined coal.

• ADA signed contract and started work on a $3.2 million project to advance the development of carbon dioxide capture technology for existing coal-fired boilers. This program is co-funded by DOE as well as several elite power generators including AEP, Southern Company, Luminant, and Xcel Energy.

Dr. Durham concluded, “The extremely unstable market conditions over the past few months have had a substantial impact on ADA’s stock price, despite the fact that our customer base and the markets we serve, primarily existing coal-fired power plants, are largely insulated from economic downturns. Additionally, the President-elect supports clean coal. We expect the new administration and Congress to act in 2009 to provide multi-pollutant federal regulations that include mercury emission control and a substantial increase in funding for carbon capture technology which would further enhance our market opportunities. We are extremely pleased with ADA’s advancements year-to-date, and are enthusiastic about the Company’s outlook for long-term growth and success.”

Separately, the Company announced that Dr. Durham will present at the Ingalls & Snyder LLC Seminar for Specialty Chemical Companies on Monday, November 10, 2008 at 9:45 am EST at The Harvard Club in New York City. The presentation slides will be filed as a Current Report on Form 8-K with the U.S. Securities and Exchange Commission on November 10, 2008, and will also be available to any interested person via the Investor Information section of the Company’s website at http://www.adaes.com.
