CO2 Conversion to Ethanol (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Scientists are seeking ways to reduce environmentally harmful levels of carbon dioxide from vehicle emissions and other sources by improving chemical processes that convert carbon dioxide gas into ethanol (molecular structure shown here) for use in liquid fuels, for example. X-ray experiments at Berkeley Lab have helped to show what's at work in the early stages of chemical reactions that convert carbon dioxide and water into ethanol.
