Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. The conversion rate reaches 32.9 ± 1.38

University of Utah engineers develop fast method to convert algae to biocrude

Green Car Congress

The new kind of jet mixer extracts lipids from algae with much less energy than the older extraction method, a key discovery that now puts this form of energy closer to becoming a viable, cost-effective alternative fuel. However, scalable high energy density alternatives to fossil fuels remain challenging. —Tseng et al.

Evonik and Siemens launch phase 2 of Rheticus: butanol, hexanol from CO2 and water using renewable electricity and bacteria

Green Car Congress

The goal is to develop an efficient and powerful test plant that will use carbon dioxide and water as well as electricity from renewable sources and bacteria to produce specialty chemicals. The first unit comprises two electrolyzers which convert H 2 O and CO 2 to H 2 and CO.

New halogen conversion-intercalation chemistry enables high-energy density aqueous Li-ion battery

Green Car Congress

Combining this cathode with a passivated graphite anode, the team created a 4V-class aqueous Li-ion full cell with an energy density of 460 Wh kg -1 of total composite electrode and about 100% Coulombic efficiency. At 460 Wh kg -1 , the energy density of the full cell is greater than that of state-of-the-art non-aqueous LIBs.
