                                    Market

             Company Notes Its Existing Capacity to Win More Work

HIGHLANDS RANCH, Colo., May 2, 2013 (GLOBE NEWSWIRE) -- ADA-ES, Inc.
(Nasdaq:ADES) ("ADA") today announced that it has recently received awards and
letters of intent to award for approximately $30 million in Activated Carbon
Injection (ACI) and Dry Sorbent Injection (DSI) systems from multiple
utilities. Work has begun on some of the projects and deliveries of the
systems are scheduled to begin in 2014.

These awards are the result of the recent EPA Mercury and Air Toxics Standard
(MATS), which requires coal-fired power plants to reduce emissions of mercury
and sulfuric, hydrochloric and other acid gases by April 2015.ADA believes
that the MATS and other emission control regulations could generate a total
market in excess of $1 billion for ACI and DSI systems. Since the MATS market
commenced in 2011, ADA has won or received letters of intent to award
contracts currently valued at approximately $75 million for DSI and ACI
systems.We are currently working on bids or discussing potential projects for
ACI and DSI systems in excess of $180 million.

Dr. Michael Durham, President and CEO of ADA, stated, "We are very pleased to
be awarded these projects by our customers and proud to provide them with
solutions to ensure compliance with the new federal rules.The market for
equipment to meet the federal MATS rules is well underway and evolving as we
expected. ADA has taken a number of steps to prepare for this market,
including the August 2012 acquisition of the assets of Bulk Conveyor
Specialist, Inc., a leading provider of DSI systems. In addition, we have
grown our engineering capabilities and have put in place arrangements with
various suppliers and component manufacturers to meet the growing market
demand. With the increase in cash flows from our Refined Coal business,
including the recent $10 million payment from the sale of a new facility, we
have the resources to execute effectively on this rapidly growing business and
help our customers meet the MATS timelines."
