CO2 Solutions Announces Extension of Agreement with Codexis

TSXV: CST         
Outstanding shares: 79,687,836

QUÉBEC CITY, May 21, 2013 /CNW/ - CO2 Solutions Inc. (TSXV: CST) is pleased to announce that it has renewed until March 31, 2015 its Joint Development Agreement (JDA) with Codexis, Inc. ("Codexis") to continue the development and deployment of CO2 Solutions' enzymatic carbon capture technology.

Under the amended and restated JDA, CO2 Solutions' proprietary enzymatic method for the efficient capture of carbon dioxide from power plants, oil production operations and other large sources of emissions will continue to benefit from Codexis' directed enzyme evolution technology and enzyme production capabilities. CO2 Solutions' technology uses the natural enzyme, carbonic anhydrase, to enhance the efficiency of CO2 capture from industrial emission sources, at lower cost than conventional carbon capture technology. Codexis' technology has dramatically improved this enzyme's ability to function in harsh industrial conditions. Carbonic anhydrase provided by Codexis is now suitable for pilot and demonstration testing in CO2 Solutions' carbon capture projects.  Carbonic anhydrase is found in humans and other living organisms and is critical in the efficient management of CO2 during respiration.

Commenting on the agreement, Evan Price, President and CEO of CO2 Solutions remarked, "We are pleased to extend our agreement with Codexis.  With this continued collaboration, CO2 Solutions intends to continue to capitalize on the opportunities that it affords to help bring this technology to the North American and global markets and provide a solution for the efficient, large‐scale mitigation of greenhouse gas emissions, including CO2 Solutions' recently announced project in the Alberta oil sands."
