Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

A study by a team of researchers from Technische Universität Berlin (TUB) and Fritz-Haber-Institut der Max-Planck-Gesellschaft has found that direct seawater splitting for hydrogen production has substantial drawbacks compared to conventional water splitting and offers almost no advantage. Additionally, H 2 O is needed for water splitting.

Researchers discover novel water-assisted approach to double or triple rate of furfural conversion

Green Car Congress

Researchers at the University of Oklahoma, in collaboration with the University of Tulsa, have a novel approach for the water-assisted upgrading of the renewable chemical furfural, doubling or tripling the rate of conversion. Energy and water are interconnected in the production of renewable fuels. —Zhao et al.

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%

Japan team reports pathway to green ammonia: photocatalytic conversion of nitrogen with water

Green Car Congress

Researchers in Japan report that a commercially available TiO 2 with a large number of surface oxygen vacancies, when photo-irradiated by UV light in pure water with nitrogen—successfully produces ammonia (NH 3 ). As a result of this, NH 3 is produced from water and N 2 under ambient conditions by using sunlight as energy source.

Toyota and DIFFER partner on direct solar production of hydrogen from humid air, rather than water

Green Car Congress

The Dutch Institute for Fundamental Energy Research ( DIFFER ) is partnering with Toyota Motor Europe (TME) to develop a device that absorbs water vapor, and splits it into hydrogen and oxygen directly using solar energy. This first prototype achieved 70% of the performance that is obtained when an equivalent device is filled with water.

Argonne team combines two protein complexes to make hydrogen fuel from water

Green Car Congress

Researchers from the US Department of Energy’s (DOE) Argonne National Laboratory have combined two membrane-bound protein complexes to perform a complete conversion of water molecules to hydrogen and oxygen. An open-access paper describing their work is published in the journal Chemical Science. —Lisa Utschig. ?. Soltau, Karen L.

EU project HyFlexFuel converted sewage sludge and other biomasses into kerosene by hydrothermal liquefaction (HTL); SAF

Green Car Congress

For the future, it will be important to commercialize advanced biofuel conversion technologies, which utilize a broader and more sustainable feedstock base. Under these conditions, biomass is converted into a crude bio-oil, which is separated from the process water behind the reactor.
