Electro-biodiesel: Scientists make 45x more efficient fuel from CO2


Scientists develop electro-biodiesel from CO2 with 45x efficiency, paving the way for carbon-negative fuel production.

“This novel idea can be applied to the circular economy to manufacture emission-negative fuels, chemicals, materials and food ingredients at a much higher efficiency than photosynthesis and with fewer carbon emissions than petrochemicals,” said Yuan, who began the work with Dai at Texas A&M University. Microbes then converted the intermediates into lipids, or fatty acids, and ultimately became biodiesel feedstock, said Yuan, also director of the National Science Foundation-funded Carbon Utilization Redesign for Biomanufacturing-Empowered Decarbonization (CURB) Engineering Research Center (ERC). “This research proves the concept for a broad platform for highly efficient conversion of renewable energy into chemicals, fuels and materials to address the fundamental limits of human civilization,” Yuan said.
