HIGHLANDS RANCH, Colo. -- February 11, 2013

ADA-ES, Inc. (NASDAQ: ADES) (“ADA” or the “Company”) is pleased to announce
the appointment of Kim B. Clarke to the Company’s Board of Directors. Ms.
Clarke, an independent director, will be a member of the Compensation, and
Nominating and Governance Committees of the Board. Ms. Clarke’s term will run
until ADA’s next annual meeting of shareholders at which directors are
elected. Ms. Clarke and Alan Bradley Gabbard, who was appointed to the Board
in November 2012, will be members of a slate of nine directors that the Board
plans to propose at the next annual meeting of shareholders. In connection
with proposing this slate of nine directors, the Board plans to reduce the
size of the board from 11 directors to nine to reflect the retirement of two
current directors effective as of such meeting.

Ms. Clarke has over 35 years of experience in human resources, safety and
information technology, and has significant experience in energy and a number
of service industries. Ms. Clarke has served as Senior Vice President and
Chief Administrative Officer of Key Energy Services, Inc. (NYSE: KEG) since
2008 and served as Vice President and Chief People Officer from 2004 through
2007. Prior to Key Energy Services, Inc., she served as the Vice President of
Human Resources for GC Services LP and Vice President Human Resources for
Browning-Ferris Industries. Ms. Clarke received a Bachelor of Science degree
in human resources from the University of Houston in 1982 and completed the
Director Development Program at the Kellogg School of Management at
Northwestern University. She currently serves as Chairperson of the University
of Houston College of Technology Dean’s Board of Advisors.

Refined Coal

The Company is currently operating eight Refined Coal (RC) facilities, four of
which are leased to two different RC investors. ADA continues to expect to
complete a contract for a fifth RC facility with a new RC investor later this
month, which will follow the completion of a debt restructuring associated
with the sale of the power plant where this RC facility is operating.

Commenting on the outlook for the RC business, Dr. Michael D. Durham,
President and CEO, said “We look forward to closing this transaction with the
new RC investor and expect to work with them and other RC investors on future
projects. In addition, we are encouraged by indications that the IRS is
planning to release clarifications regarding potential recommended structures
for tax-financing partnerships. We also understand that the IRS will resume
the process for releasing Private Letter Rulings for RC, which was halted in
August 2012. We expect that this clarity will help accelerate the closing of
contracts for a number of RC facilities throughout this year and into 2014.”

The Company expects to provide further updates on its RC business later this
month, with additional details to be released when the Company reports its
2012 results in early March.
