Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

The catalyst shows a carbon dioxide conversion through hydrogenation to hydrocarbons in the aviation jet fuel range of 38.2%, with a yield of 17.2%, and a selectivity of 47.8%, and with an attendant low carbon monoxide (5.6%) and methane selectivity (10.4%). In brief, the Fe–Mn–K catalyst shows a CO 2 conversion of 38.2% —Yao et al.

USC team develops novel organic redox flow battery for large-scale energy storage

Green Car Congress

Scientists at USC have developed a novel water-based Organic Redox Flow Battery (ORBAT) for lower cost, long lasting large-scale energy storage. ORBAT employs two different water-soluble organic redox couples on the positive and negative side of a flow battery. Click to enlarge. —Yang et al. —Yang et al.

Liverpool team develops better material for PEM fuel cells; porous organic cage solids with 3D protonic conductivity

Green Car Congress

In the search for more effective PEMs, reseachers have looked to porous solids such as metal-organic frameworks (MOFs) or covalent organic frameworks. However, there are few examples of proton conduction in porous organic molecular solids. … We demonstrate this concept for a range of crystalline porous organic cages.

Study indicates warming Arctic is remobilizing persistent organic pollutants into the atmosphere

Green Car Congress

A new study by researchers from Canada, Norway and China indicates that warming in the Arctic is revolatilizing persistent organic pollutants (POPs) that have accumulated in sinks such as water and ice. Their paper appears in the journal Nature Climate Change. —Ma et al. Nature Climate Change doi: 10.1038/nclimate1167.

MBL begins first test of tropical seaweed farming for biofuels production

Green Car Congress

A team of researchers led by Loretta Roberson, associate scientist at the Marine Biological Laboratory, Woods Hole, has installed the first seaweed farm in Puerto Rico and US tropical waters. Puerto Rico has stable warm temperatures and ample sunlight year-round, as well as a wide range of exposure to prevailing winds and waves.

RIKEN researchers develop bio-inspired catalyst that splits water at neutral pH

Green Car Congress

Plants use photosynthesis to convert carbon dioxide and water into sugars and oxygen. The process starts in a cluster of manganese, calcium and oxygen atoms at the heart of a protein complex called photosystem II, which splits water to form oxygen gas, protons and electrons.
