Akermin says biocatalyst testing is turning out well for CO2 capture

Technology provider Akermin Inc. said June 3 that there has been a successful commissioning and testing of its proprietary Biocatalyst Delivery System at the National Carbon Capture Center in Wilsonville, Ala.

The pilot unit has operated continuously for several weeks capturing close to 90% of the CO2 from flue gas with significant rate enhancement and no degradation in performance, the company said. After several weeks of continuous operation, this marks the longest and largest demonstration of an enzyme-catalyzed process for CO2 capture.

“These results validate our technology and our approach and support scale-up and demonstration across multiple markets,” said Barry Blackwell, Akermin President and CEO. “We are excited to achieve such excellent results with our initial field pilot test. This achievement is a testament to the hard work of the entire Akermin team.”

The company also acknowledged the support of the U.S. Department of Energy’s National Energy Technology Laboratory (DOE-NETL), and project partners and suppliers that include: Novozymes, EPIC Systems, the National Carbon Capture Center (NCCC), Battelle and the Pacific Northwest National Laboratory (PNNL). 

The pilot plant will continue operations for several months with no replenishment of enzyme, Akermin said. The operating data provide technical and economic validation for CO2 removal from target markets such as biogas upgrading, liquefied natural gas (LNG) and ammonia production, and support larger-scale field pilot testing for natural gas- and coal-fired power plants, the company added.

In recent months, Akermin said it has developed a next generation approach using an environmentally-friendly salt solution and proprietary process scheme that enables on-line biocatalyst replacement. This solution will be demonstrated in future projects and can be applied to further reduce the cost of CO2 emissions reduction for large-scale industrial operations and natural gas- and coal-fired power plants.

Akermin is a cleantech technology development company located at BRDG Park at the Danforth Plant Science Center in St. Louis, Mo. Akermin’s multi-disciplined approach integrates enzymes within proprietary delivery systems that can be incorporated into conventional processes for energy efficient, green CO2 management solutions.

Novozymes is a leader in bioinnovation and enzyme research, development and production. Headquartered in Bagsvaerd, Denmark, the company maintains its North American regional headquarters in Franklinton, N.C.

EPIC Systems is a St. Louis-based engineering and fabrication company that provides pilot and production scale process plants and systems. 

Located in Wilsonville, Ala., and sponsored by DOE, the NCCC provides facilities to test developers’ technologies under commercially representative conditions with coal-derived flue gas and syngas, thereby accelerating the development of cost-effective CO2 capture technologies.
