Codexis reports dramatic increase of enzyme carbon dioxide capture performance

Publish date: September 1, 2011

The chemical company Codexis reports a two-million fold increase in enzyme performance for CO2 capture.

At a CO2 Capture Technology Meeting in Pittsburgh in August 2011, Codexis presented results proving its customized carbonic anhydrase (CA) enzyme performance to be about two million times more efficient than that of natural forms of the enzyme. The CA enzymes could catalyze carbon capture under industrial conditions. Evolved enzymes are functional and stable in relatively inexpensive, energy efficient solvents for 24 hours at temperatures greater than 90 degrees C – the company says. Use of carbon dioxide capture solvents with those enzymes is expected to reduce the costs and energy requirements to capture CO2 produced by coal-fired power plants.

 

Company’s work is supported by a grant from the DoE’s ARPA-E Recovery Act program and is jointly developed with CO2 Solution Inc, Canada. By using its patented CodeEvolver(TM) evolution technology the company develops processes to reduce CO2 emissions from coal-fired power plants.
