SCR-Tech Teams With AEP and Southern Company to Optimize Sulfur Dioxide Conversion in Regenerated SCR Catalyst

CHARLOTTE, NC -- (MARKET WIRE) -- September 6, 2005 -- SCR-Tech, a subsidiary of Catalytica Energy Systems, Inc. (NASDAQ: CESI), announced today that it has entered into a development partnership with American Electric Power (NYSE: AEP), and Southern Company (NYSE: SO), to measure and evaluate the reduction conversion in sulfur dioxide (SO2) to sulfur trioxide (SO3) demonstrated by regenerated Selective Catalytic Reduction (SCR) catalyst. The goal of this effort is to optimize SCR-Tech's regeneration process to further minimize SO3 formation while maintaining or exceeding full catalytic activity.

SCR-Tech's proprietary cleaning and regeneration process extends the life of SCR catalyst by achieving full restoration of its activity level and NOx reduction performance. In addition to offering SCR operators a lower cost alternative to purchasing new catalyst, the use of regenerated SCR catalyst has been demonstrated to reduce the conversion of SO2 to SO3 by up to 35% when compared with the conversion rate typically achieved by fresh catalyst. Research has shown that minimizing the amount of SO3 produced through the oxidation of SO2 within the catalyst can help coal-fired power generating facilities minimize SO3 emissions and their related corrosive costs.

Under the terms of the joint development initiative, the three companies will work together over the next several months to test and quantify the SO2 to SO3 conversion rates demonstrated by SCR catalyst regenerated under a variety of conditions, and benchmark the performance of this regenerated catalyst against new and deactivated catalyst. The data collected throughout the program will be used to ascertain the optimal balance between catalyst activity level and SO2 conversion specific to the varied operating conditions of coal-fired boilers.

Data collected by SCR-Tech will be used to further tailor its catalyst regeneration process to achieve maximum restoration of catalytic activity while minimizing SO2 to SO3 conversion. Results from the jointly funded project, which is scheduled to be completed in the first half of 2006, are expected to be published in a technical paper and presented at an industry conference next year.

SCR-Tech President Bill McMahon, commented, "SCR-Tech is committed to continuous technology innovations to help our customers improve performance and reduce their costs associated with SCR systems. We look forward to working closely with two of the leading and most respected utilities in the world to further enhance our service offerings and expand our spectrum of cost-effective environmental compliance solutions. By optimizing our regeneration process to accommodate the diversity of fuels, firing systems and catalyst types available in the industry, we believe we will be able to create additional value for AEP , Southern Company, and all of our future customers."

Tom Hart, Manager of Air Emission Control Equipment Engineering of AEP's Engineering Technical and Environmental Services organization, stated, "AEP has long been a leader in research and development efforts designed to improve emissions-control technologies for existing coal-fired generation or to develop clean-coal technologies for future generation. This project with SCR-Tech is an important one, since its results may help to minimize the creation in SO3 from existing emissions-control systems while controlling the cost of catalyst used in the systems, both important factors to companies like AEP that are committed to generating electricity in a cost-effective, environmentally responsible manner."

Steve Wilson, Director of Research and Technology Management for Southern Company's Research & Environmental Affairs organization, stated, "We pride ourselves in being an industry leader in finding cleaner ways to produce electricity. As one of SCR-Tech's first customers, we've had a long-standing relationship and have experienced first-hand the cost benefits and emissions reduction performance that can be achieved through the use of regenerated catalyst. We believe that this technology shows great promise in further reducing the total amount of SO3 that is produced by the SCR catalyst through improved understanding and optimization of this process."
