    Patent covering use of enzyme for carbon capture at coal fired power
    plants is fourth new patent received by CO2 Solution in 2009

QUEBEC, Nov. 3 /PRNewswire-FirstCall/ - CO2 Solution Inc. ("CO2 Solution" or the "Company") is pleased to announce that it has received a new United States patent, 7,596,952 - Process and a plant for recycling carbon dioxide emissions from power plants into useful carbonated species. The patent provides for exclusivity in the field of using the enzyme carbonic anhydrase, or an analog thereof, for the capture of CO2 from any fossil power plant, where captured CO2 is converted into a carbonated species. The company believes that the patent has potentially significant value for efficient carbon capture in coal and other fossil fuel power plants

This patent is the fourth new patent received by CO2 Solution during 2009, in addition to the following:

    U.S. Patent 7,514,056 - Process and installation for the fractionation of
    air into specific gases; Protects the use of carbonic anhydrase for use
    in efficiently capturing CO2 from compressed air as part of an air-
    separation unit for the production of oxygen. The Company believes that
    the patent can address the cost challenge that conventional air-
    separation processes face due to ever increasing CO2 concentrations in
    ambient air. The specialty gas industry has shown interest in the patent
    and CO2 Solution intends to pursue possible commercialization
    opportunities therein.

    U.S. Patent 7,521,217 - Carbonic anhydrase having increased stability
    under high temperature conditions; Covers the Company's proprietary
    enzyme 'mutants' which have increased thermal and industrial stability
    through genetic engineering.

    Canadian Patent 2,443,222 - A process and plant for the production of
    Portland cement clinker (equivalent U.S. Patent 6,908,507); Covers the
    use of the enzyme for the capture of CO2 from cement plant flue gas and
    the production of calcium carbonate for reuse in the cement making
    process, and has the potential to materially reduce overall carbon
    emissions from the cement production process.

Regarding the issuance of these four new patents, Mr. Glenn Kelly, President & CEO stated: "These patents build on our already broad intellectual property portfolio in enzymatic carbon capture, at a time when industry is increasingly searching for new ways to capture CO2 that are more efficient than conventional scrubbing technology. There has recently been heightened interest in the use of carbonic anhydrase in this context. As such, we believe these patents further solidify CO2 Solution's technology leadership position in the field, and in the rapidly growing carbon capture space."

About CO2 Solution

Based in Quebec City, CO2 Solution Inc. has developed a proprietary bio-technological platform for the efficient capture of carbon dioxide (CO2), the most important greenhouse gas (GHG), from power plants and other large stationary sources of emissions. The Company's technology platform exploits the natural power of a biocatalyst (enzyme), carbonic anhydrase, which functions within humans and other mammals to manage CO2 during respiration. CO2 Solution has successfully adapted the enzyme to function within an industrial environment, and thus has taken advantage of a biomimetic approach to CO2 capture based on millions of years of evolution. The Company is commercializing its technology for coal fired power generation, the oil sands and other CO2-intensive industries where a low-cost capture solution is key to meeting climate change legislation in a cost effective manner.

CO2 Solution's technology platform is protected by several North American and European patents, including the use of carbonic anhydrase for CO2 capture and release in a packed column system. News releases and additional information can be found at www.co2solution.com.
