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. 1 were obtained, with conversions greater than 80% at 600 °C.

New catalyst improves conversion of CO2 to syngas

Green Car Congress

Researchers from the University of Illinois at Chicago (UIC) have identified molybdenum disulfide as a promising cost-effective substitute for noble metal catalysts for the electrochemical reduction of carbon dioxide. The new catalyst produces syngas, a mixture of carbon monoxide plus hydrogen. —Mohammad Asadi.

UK team produces hydrogen from fescue grass via photocatalytic reforming

Green Car Congress

A team of researchers from the UK’s Cardiff University’s Cardiff Catalysis Institute and Queen’s University Belfast have shown that significant amounts of hydrogen can be unlocked from fescue grass—without significant pre-treatment—using sunlight and a metal-loaded titania photocatalyst. Reaction conditions: 0.36 g

Argonne team finds copper cluster catalyst effective for low-pressure conversion of CO2 to methanol with high activity

Green Car Congress

Researchers at Argonne National Laboratory have identified a new material to catalyze the conversion of CO 2 via hydrogenation to methanol (CH 3 OH): size-selected Cu 4 clusters—clusters of four copper atoms each, called tetramers—supported on Al 2 O 3 thin films.

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.

Stanford researchers develop copper-based catalyst that produces ethanol from CO at room temperature; potential for closed-loop CO2-to-fuel process

Green Car Congress

Researchers at Stanford University have developed a nanocrystalline copper material that produces multi-carbon oxygenates (ethanol, acetate and n-propanol) with up to 57% Faraday efficiency at modest potentials (–0.25?volts volts versus the reversible hydrogen electrode) in CO-saturated alkaline water. volts to –0.5?volts Christina W.

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”.
