Penn team proposes liquid-organic hydrogen carriers as endothermic fuels for hypersonic aircraft

Green Car Congress

A team at the University of Pennsylvania is proposing the use of a liquid-organic hydrogen carrier (LOHC)—specifically, 1,2,3,4 -tetrahydroquinoline (THQ)—for use as an endothermic fuel for thermal protection of hypersonic aircraft engines. A paper on their work is published in the journal Fuel. earlier this year.

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

Researchers from Japan’s NIMS (National Institute for Materials Science), the University of Tokyo and Hiroshima University have jointly conducted a techno-economic analysis for hydrogen production from photovoltaic power generation (PV) utilizing a battery-assisted electrolyzer. This approximately converts to US$1.92

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

In the new UMass approach, the hydroprocessing increases the intrinsic hydrogen content of the pyrolysis oil, producing polyols and alcohols. The zeolite catalyst then converts these hydrogenated products into light olefins and aromatic hydrocarbons in a yield as much as three times higher than that produced with the pure pyrolysis oil.

Researchers produce hydrogen from water and charcoal mix at room temperature using laser pulses

Green Car Congress

Researchers at Wakayama University in Japan have produced a mixture of hydrogen and carbon monoxide gas by irradiating a mixture of carbon powder and distilled water with intense nanosecond laser pulses at room temperature. Electrodes or any other photocatalysts were not used to produce the hydrogen. Credit: ACS, Akimoto et al.

USC team develops highly efficient catalyst system for converting CO2 to methanol; 79% yield from CO2 captured from air

Green Car Congress

Researchers at Loker Hydrocarbon Research Institute and Department of Chemistry, University of Southern California, have developed a highly efficient homogeneous Ru-based catalyst system for the production of methanol (CH 3 OH) from CO 2 and H 2 in an ethereal solvent (initial turnover frequency = 70 h −1 at 145 °C).

Copper foam catalyst yields different product slate from CO2 than smooth electrodes; importance of catalyst architecture

Green Car Congress

A catalyst made from a foamy form of copper has different electrochemical properties from catalysts made with smooth copper in reactions involving carbon dioxide, according to a new study by a team from Brown University. The foams are made by depositing copper on a surface in the presence of hydrogen and a strong electric current.

Purdue, EPFL team propose Hydricity concept for integrated co-production of H2 and electricity from solar thermal energy

Green Car Congress

Researchers from Purdue University and École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are proposing a new integrated process involving the co-production of hydrogen and electricity from solar thermal energy—a concept they label “hydricity”.
