Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

Hydrogen production pathways include low- and high-temperature electrolysis; solar thermochemical disassociation; photobiological splitting (four pathways: direct and indirect biophotolysis using hydrogenase and nitrogenase); gasification (coal, biomass); steam reforming (methane, ethanol); and partial oxidation.

RAND study concludes use of alternative fuels by US military would convey no direct military benefit; recommends energy efficiency instead

Green Car Congress

If the US military increases its use of alternative jet and naval fuels that can be produced from coal or various renewable resources, including seed oils, waste oils and algae, there will be no direct benefit to the nation’s armed forces, according to a new RAND Corporation study.

Study finds copper catalysts work better at converting CO2 to renewable fuel when they gain and lose oxygen atoms

Green Car Congress

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) and Caltech have found that copper that was once bound with oxygen is better at converting carbon dioxide into renewable fuels than copper that was never bound to oxygen. Drisdell and his colleagues say their discovery is an important advance towards that goal.
