CO2 Solution may have the key to large scale carbon capture and storage

GLOBE-Net, November 10, 2010 - A small Quebec City-based company - CO2 Solution - has developed a patented enabling technology for the efficient capture of carbon dioxide (CO2), the most important greenhouse gas (GHG), from power plants and other large stationary sources of emission.

The technology uses the enzyme, carbonic anhydrase-the fastest known catalyst for carbon dioxide absorptions, which VP of Business Development Jonathan Carley likened to "an industrial lung."

"We use basically nature's best solution to this problem," he said. The enzyme is industrially optimized and introduced into conventional carbon dioxide scrubbing technology. It is used to accelerate carbon dioxide absorption in the system, which the company said results in lower process costs.

Once the CO2 is captured, the enzyme assists in subsequent production of pure CO2 for underground storage and/or use in oil recovery.  In this way, the Company has taken advantage of a biomimetic approach to CO2 capture based on millions of years of evolution.

Conventional CO2 capture with available technology, based primarily on the use of amine solvents, is an energy intensive process that involves heating the solvent to high temperature to strip the CO2 (and regenerate the solvent) for underground sequestration. 

The conventional use of amines involves an associated capture cost of approximately US $60 per ton of CO2, which represents approximately 80% of the total cost of carbon capture and sequestration (CCS).   This large cost for the capture portion has, to present, made large scale CCS nonviable.

As an innovative solution to this problem, CO2 Solution has achieved significant results in applying the enzyme to conventional capture solvents (amines and others) to improve their performance.  These results point to the ability of the enzyme to materially lower the cost of carbon capture by allowing a reduction in the size of the absorber equipment and lowering process energy requirements.

CO2 Solution is presently 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.

The 16-employee firm has raised about $20 million and is currently seeking $10 million for initial field demonstrations of its technology, Carley said. The company raised a $1 million private placement in 2006.

A commercial launch is expected in 2013, with the company planning to sell its technology through engineering, procurement and construction partners. It's also seeking additional strategic partners, with one agreement already underway with Codexis, Inc., a California-based company.

In May 2010 Codexis was selected to receive up to a $4.7 million from the U.S. Department of Energy, for the development of innovative technology, in collaboration with CO2 Solution, to remove carbon dioxide from coal-fired power plant emissions.

In July this year, the first joint public presentation on the CO2 Solution technology was made at the 4th Annual Carbon Capture and Sequestration Business Summit in Washington, DC  by James Lalonde, Ph.D., Vice President of Biochemistry and Engineering Research and Development, Codexis and Jonathan Carley, Vice President, Business Development, CO2 Solution.

Glenn Kelly, President & CEO of CO2 Solution, was the former President & COO of Rabaska Inc., a subsidiary of Gaz Metro, Gaz de France and Enbridge Inc.  Previously, Mr. Kelly was President of Intragaz Inc., a company specializing in the development and operation of underground natural gas storage facilities.

As the search for less costly methods for the capture and storage of carbon dioxide continues, technologies such as those developed by CO2 Solution will become more interesting to investors and large scale utility operators.

Clearly, CO2 Solutions is an innovators to watch.

The article states that the use of the enzyme should materially lower the cost of carbon capture by allowing a reduction in the size of the absorber equipment and lowering process energy requirements. However, no figures are given. It is stated that using conventional amines solvents cost about $ 60 per t of CO2 captured. With souch cost $220 per t of carbon capture it should be very much cheaper to use tree plantations, the cost of sequestration should be $25 to $30 per t of C. This could be used for energy purposes and the cycle repeated!
