Researchers develop highly efficient organometal halide perovskite photoelectrodes for water splitting

Green Car Congress

Photoelectrochemical (PEC) water splitting based on solar energy is one promising approach for the production of green hydrogen. However, its widespread application is limited by a lack of efficient photoanodes for catalyzing the rate-limiting oxygen evolution reaction (OER), an important reaction in PEC water splitting. 202300951

ULEMCo delivers water tanker converted to use hydrogen dual fuel

Green Car Congress

UK-based ULEMCo has worked with Yorkshire Water to produce what is believed to be the first water tanker anywhere to operate on hydrogen fuel. tonne bowser has been converted from a standard truck to use hydrogen dual fuel, an approach that allows fleet managers to transition more quickly to low carbon operation.

Blue Biofuels achieves full conversion (99%+) of cellulosic material to sugars on repeatable basis

Green Car Congress

reports that it has achieved full conversion ( 99% + ) of king grass cellulosic material to water soluble sugars on a repeatable basis. This conversion occurs with a reaction time of less than one minute. Full conversion is the most efficient use of the feedstock possible and exceeds earlier projections.

BMW i Ventures invests in Prometheus Fuels; CO2 air-capture and conversion to carbon-neutral gasoline

Green Car Congress

BMW i Ventures has invested in Prometheus Fuels ( earlier post ), a company removing CO 2 from the air and turning it into zero-net carbon gasoline that it will sell at gas stations, at a price that competes with fossil fuels, starting as early as this year. to C 2 fuel products such as ethanol.

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.

Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

Researchers at the University of Oxford have developed a method to convert CO 2 directly into aviation fuel using a novel, inexpensive iron-based catalyst. The conversion reaction also produces light olefins—ethylene, propylene, and butenes—totalling a yield of 8.7%. and selectivity to C 8 –C 16 hydrocarbons of 47.8%
