Company expands its leading patent position in the use of carbonic anhydrase for efficient carbon captureTSX-V: CST Outstanding Shares: 79,187,836 QUEBEC CITY, May 2, 2012 /PRNewswire/ - CO 2 Solutions Inc. (TSX-V: CST), an innovator in the field of enzyme-enabled carbon capture technologies, announced today that it has received the Notice of Allowance from the U.S. Patent and Trademark Office for the issuance of US20100203619, "CO 2 ABSORPTION SOLUTION". The patent will cover the use of carbonic anhydrase (CA) in any form for carbon capture from a gas stream and with any secondary or tertiary amine solvents. This Notice demonstrates the unique nature of the Company's technology, which uses low-energy amine solvents accelerated by CA to cost-effectively capture CO 2 for reuse or sequestration. Near-term commercial applications exist for the technology, such as the processing of various industrial gasses, as well as potential long-term markets, such as flue gas treatment in the power generation and oil industry. "This new patent further solidifies our leadership position in the field of enzymatic carbon capture at a time of intense industry interest in carbonic anhydrase. It provides the ability to deploy our carbon capture technology with low-energy and more environmentally sustainable amines in industries that are using more energy-intensive and costly amines such as monethanolamine (MEA). With our technology we can provide our customers with significant operating cost savings with a 'drop-in' solution that seamlessly integrates within existing gas-treating plants", stated Glenn Kelly, President & CEO of CO 2 Solutions.
