CO2 Solutions announces issuance of U.S. patent

Process for CO2 capture using Carbonates and Biocatalysts

Quebec City, Quebec, September 10, 2014 – CO2 Solutions Inc. ( the “Corporation”) (TSX-V:CST), the leader in the field of enzyme-enabled carbon capture technology, today announced it has been granted U.S. Patent No. 8,722,391 entitled Process for CO2 capture using Carbonates and Biocatalysts with Absorption of CO2 and Desorption of Ion-rich Solution.

The patent adds even more depth to CO2 Solutions’ already-extensive U.S. patent portfolio, providing broad coverage for enzyme accelerated carbonate-based solvent processes for carbon capture. CO2 Solutions believes the patent may have significant value relative to these CO2 capture processes, especially where precipitates are produced during the absorption stage. Formation of precipitates can drastically reduce the amount of solvent to be heated to produce pure CO2 for industrial re-use. This, in turn, reduces the total energy requirement, and hence the associated costs are lower than for comparable solutions available on the market.

Evan Price, CEO of CO2 Solutions, stated, “This patent is yet another element in our robust intellectual property portfolio which we believe effectively covers all viable routes to commercialization of carbonic anhydrase enzyme-based systems for the capture of CO2.”
