Shell, Codexis Deepen Biofuel Collaboration

March 16, 2009

REDWOOD CITY, CA --- Royal Dutch Shell and Codexis Inc. announced an expanded agreement to develop better enzymes that could accelerate commercialization of next-generation biofuels. 

Shell also increased its equity stake in Codexis and will take an additional seat on the company's board. Codexis has developed biocatalytic chemical processes aimed at reducing manufacturing costs across a broad range of industries, including transportation fuels. 

As part of the agreement, Codexis will work closely with Shell and Iogen Energy Corp. to enhance the efficiency of enzymes used in the Iogen cellulosic ethanol production process. The Iogen demonstration plant in Ottawa, Canada, currently produces hundreds of thousands of liters of cellulosic ethanol from agricultural residue, such as wheat straw. 

The research program with Codexis aims to enhance the Iogen process and shorten the timeline to its full-scale commercial deployment.  Iogen's technology uses enzymes to break down the cellulose in agricultural fiber and convert it to sugars, which are then fermented and distilled into ethanol. 

The new Shell-Codexis deal also continues the collaboration announced in November 2007 to investigate other biofuels, researching new enzymes to convert biomass directly into components similar to gasoline and diesel. Codexis will expand research at a center in the U.S. and at a new center in Budapest, Hungary. 

"The expert Codexis team will make a real difference in the race toward full-scale commercial production of biofuel from non-food sources," said Graeme Sweeney, Shell executive vice president for future fuels and CO2. "Better enzymes will improve efficiency and help lower costs."  

"In just over two years, our biofuels collaboration with Shell has grown from a pilot project to a significant multifaceted program to create commercial-scale biofuels from non-food sources," added Alan Shaw, Codexis president and CEO.
