Shell and Codexis expanding cellulosic ethanol development
Other biocatalysts that Codexis is developing go beyond ethanol and might be able to convert biomass directly into the compounds that make up gasoline and diesel fuel. These compounds contain longer carbon chains than ethanol and have greater energy density. By producing something more chemically similar to gasoline or diesel, the fuels could be used in existing vehicles without modification and without some of the corrosion issues that ethanol is subject too.
