Biofuel vs. Artificial Photosynthesis (image) University of Illinois at Urbana-Champaign Caption This image shows biofuel production (left) compared to fuel produced via artificial synthesis. Crops takes in CO2, water and sunlight to create biomass, which then is transferred to a refinery to create fuel. In the artificial photosynthesis route, a solar collector or windmill collects energy that powers an electrolyzer, which converts CO2 to a synthesis gas that is piped to a refinery to create fuel.
