Codexis (CDXS) and CO2 Solution (CST.V) Unveil Carbon Capture Program

REDWOOD CITY, CA and QUEBEC CITY, July 13 /PRNewswire-FirstCall/ – Codexis, Inc. (Nasdaq:CDXS – News) and CO2 Solution Inc. (TSX-V:CST.v – News) today will make the first joint public presentation on their program to develop carbon capture technology to reduce pollution from coal-fired power plants.

The presentation is being made at the 4th Annual Carbon Capture and Sequestration Business Summit in Washington, DC (www.infocastinc.com/carbon10) by James Lalonde, Ph.D., Vice President of Biochemistry and Engineering Research and Development, Codexis and Jonathan Carley, Vice President, Business Development, CO2 Solution.

In May 2010, Codexis was selected to receive up to a $4.7 million ARPA-E Recovery Act program grant from the U.S. Department of Energy for development of innovative technology to remove carbon dioxide from coal-fired power plant emissions. The grant was one of 37 research projects which the DoE said “could fundamentally change the way the country uses and produces energy.” Coal-fired power plants are major emitters of carbon dioxide, a significant greenhouse gas. The grant supports development of biocatalysts for more efficient carbon capture from these plants.

Codexis and CO2 Solution are jointly developing this technology, and the companies will describe their development program today. Current carbon capture technology is inefficient and too expensive for large scale deployment. The collaboration focuses on development of customized carbonic anhydrase (CA) biocatalysts and their process applications that have the potential to enable cost-effective, industrial scale capture of CO2 from power plant flue gases. Program results to date have demonstrated the combined proprietary technologies can be used to create CA biocatalysts with improved absorption and stability in industrial conditions.

About the Codexis – CO2 Solution Collaboration

A technology development collaboration between Codexis and CO2 Solution was announced in December 2009. The technology is based on the use of customized CA biocatalysts that have the potential to enable cost effective, energy efficient processes for the capture of carbon dioxide. Carbonic anhydrase is an enzyme that efficiently catalyzes CO2 in living systems. As part of the collaboration, Codexis completed a CDN$2 million equity investment in CO2 Solution and holds 16.6% of CO2 Solution’s issued and outstanding common shares.

About CO2 Solution

CO2 Solution is an innovator in the field of enzyme enabled carbon capture and has been actively working to develop and commercialize the technology for power plants and other large stationary sources of carbon pollution. In the process, CO2 Solution has built an extensive patent portfolio covering the use of carbonic anhydrase, or analogues thereof, for post-combustion capture, including the kinetic enhancement of low-energy amine solutions for efficient CO2 absorption and regeneration.
