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.

Photocatalytic optical fibers convert water into hydrogen

Green Car Congress

Researchers at the University of Southampton have transformed optical fibers into photocatalytic microreactors that convert water into hydrogen fuel using solar energy. Alongside hydrogen generation from water, the multi-disciplinary research team is investigating photochemical conversion of carbon dioxide into synthetic fuel.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability. One way this could be achieved is by using photoelectrochemical (PEC) water splitting which directly converts water and sunlight to solar fuel (hydrogen).

Audi in new e-fuels project: synthetic diesel from water, air-captured CO2 and green electricity; “Blue Crude”

Green Car Congress

Audi’s latest e-fuels project is participation in a a pilot plant project in Dresden that produces diesel fuel from water, CO 2 and green electricity. The sunfire plant, which operates according to the “power-to-liquid” (PtL) principle, requires carbon dioxide, water and electricity as raw materials.

Bio-inspired molybdenum sulfide catalyst offers low-cost and efficient photo-electrochemical water splitting to produce hydrogen

Green Car Congress

The optimized photo-electrochemical water splitting device uses light absorbers made of silicon arranged in closely packed pillars, dotted with tiny clusters of the new molybdenum sulfide catalyst. An alternative, clean method is to make hydrogen fuel from sunlight and water via a photo-electrochemical (PEC, or water-splitting) process.

Researchers at UC Santa Barbara develop efficient and stable plasmonic water splitter; potential alternative to semiconductor-based solar conversion

Green Car Congress

Researchers at UC Santa Barbara have developed an efficient, autonomous solar water-splitting device based on a gold nanorod array in which essentially all charge carriers involved in the oxidation and reduction steps arise from the hot electrons resulting from the excitation of surface plasmons in the nanostructured gold (plasmonic water-splitter).

High-entropy oxide as high-activity electrocatalyst for water oxidation

Green Car Congress

Researchers from the University of Twente in The Netherlands have developed a new high-entropy perovskite oxide (HEO) as a high-activity electrocatalyst for the oxygen evolution reaction (OER)—the key kinetically limiting half-reaction in several electrochemical energy conversion technologies, including green hydrogen generation.
