CO2 Solutions Completes Investigatory Phase of Collaboration with Alcoa


Outstanding shares: 79,187,836 

QUEBEC CITY, July 10, 2012 /CNW/ - CO2 Solutions Inc. (TSXV: CST), an innovator in the field of enzyme-enabled carbon capture technology, announced today the completion of the initial investigatory phase of its carbon capture pilot program with Alcoa, Inc.  The project, started in April, 2011, is designed to capture and sequester industrial carbon emissions in alumina production waste, neutralize these materials and then create a commercially viable product.

The program, part of Alcoa's ongoing commitment to enhance its operational sustainability, proposed to use Alcoa's induct scrubber technology to capture carbon dioxide (CO2) emissions. After capturing the emissions, the technology treats and then uses a primary by-product of the aluminum manufacturing process known as alkaline clay, or bauxite residue, as well as other alkaline industrial residuals.

The initial stage of the project tested Alcoa's gas scrubbing process using enzymatic technology from CO2 Solutions and Codexis, Inc. Alcoa funded the project, which also received financial contributions from the U.S. Department of Energy (DOE), made available by the American Recovery and Reinvestment Act (ARRA).

The results of the initial phase of the project have been reviewed by CO2 Solutions, Codexis and Alcoa scientists and engineers. The project yielded positive results at bench scale, which confirmed the potential of the enzymatic technology for efficient CO2 capture from industrial effluent gases.

The following important, positive technical results were noted:

  • The use of CO2 Solutions/Codexis technology provided for marked increases in CO2 capture efficiency and the ability to reduce equipment sizing
  • Enzyme stability was noted in the carbonate solvent employed
  • The potential to utilize enzymes to enhance CO2 capture with a carbonate solvent was confirmed and provides the opportunity to apply this technology approach to other industrial applications

The project could not meet the DOE project completion schedule, which called for full commercial deployment by 2014 and consequently will not move ahead to the next phase at this time.  However, CO2 Solutions will continue with the further development of this application of its technology.

"While the project will not proceed as planned, the technical results validate our belief that our enzyme-enabled carbon capture technology will become commercially viable for both carbon dioxide capture and sequestration," said Glenn R. Kelly, CO2 Solutions' President and Chief Executive Officer. "The positive results from this program have already led to evaluations of our technology being undertaken with other industrial partners."
