CO2 Solutions develops new carbon capture enzyme
Testing suggests it will help lower the cost of enhanced oil recovery.
QUEBEC CITY — CO2 Solutions Inc. has developed a new high-performance carbonic anhydrase enzyme that will be used in the company’s carbon capture process.
The Quebec City-based developer of carbon capture technology said extensive bench testing showed the new enzyme, named 1T1, demonstrated longevity and catalytic performance that significantly surpassed the same characteristics of the best third-party enzymes currently used by the company.
CO2 has filed patent applications for 1T1, which it said will be used in its process for the efficient post-combustion capture of carbon dioxide with low‐energy aqueous solvents.
“To date, the large-scale adoption of CO2-driven enhanced oil recovery (EOR) has been held back by the limited availability of large volumes of low cost CO2,” said Louis Fradette, senior vice-president, process engineering and CTO. “We believe that the benefits generated by using 1T1 in our process address this issue and increase the potential for these types of applications to become reality.”
The company says initial manufacturing results suggest the production cost per unit weight of enzyme protein are likely to be substantially less than that for the third-party enzymes that are currently used.
The production of 1T1 has been outsourced to a third party, and industrial-scale batches have been manufactured.
The new enzyme will be used in the upcoming tests at the University of North Dakota Energy & Environmental Research Center (EERC), scheduled for December.
1T1 was developed with the financial assistance from the Industrial Research Assistance Program (IRAP).
