Company expands its leading intellectual property position in use of enzymes for efficient management of carbon pollution

Outstanding Shares: 79,187,836

QUEBEC CITY, Oct. 3, 2012 /PRNewswire/ - CO2 Solutions Inc. (TSX-V: CST), an innovator in the field of enzyme-enabled carbon capture technologies, announced today that it has been granted U.S. Patent 8,277,769, "PROCESS FOR TREATING CARBON DIOXIDE CONTAINING GAS". The patent broadly covers the use of the enzyme carbonic anhydrase (CA), or an analogue thereof, for the efficient capture of carbon pollution from various gas streams with any aqueous solvent or solution.

Significant industry applications of the patent for carbon management include power generation, oil refining, metals production, cement making, amongst others. The patent may be viewed here: 2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,277,769&OS= 8,277,769&RS=8,277,769.

"The issuance of this patent represents one of the strongest validations to date of our dominant intellectual property position in the field," stated Glenn Kelly, President and Chief Executive Officer of CO2 Solutions. "In addition, the patent further raises the barrier to entry for any potential competitor to CO2 Solutions in the field of enzymatic carbon capture, which has seen heightened interest recently from prospective North American commercial partners."

The issuance of this patent follows the previously announced allowance of U.S. Patent 8,192,531, "CO2 ABSORPTION SOLUTION". U.S. Patent 8,192,531 covers the use of CA for carbon capture with any secondary or tertiary amine solvent with significant near-term application in the treating of various industrial gasses, including natural gas processing.

Combined, these two patents increase the Company's reach into the growing opportunity for the management and beneficial reuse of carbon dioxide in the United States. This is particularly the case in large jurisdictions such as California, which are implementing cap and trade systems that impose penalties on carbon emissions and can provide economic opportunities for the capture of these emissions.
