French team finds light-driven algal enzyme that converts fatty acids to hydrocarbons

Green Car Congress

A team of researchers in France has discovered an algal photoenzyme that catalyzes the decarboxylation of free fatty acids to n-alkanes or -alkenes in response to blue light. Many organisms—photosynthetic and nonphotosynthetic—use light for processes such as growth, development, and metabolism. variabilis or C.

Hilux, Ranger EV ute conversions by Roev from $47,990 as company confirms 2023 production

EV Central

Australian manufacturer Roev plans to do just that from 2023 by converting Toyota Hiluxes and Ford Rangers to electric, with conversions priced from $47,990. That makes the locally-converted utes cheaper than the LDV eT60 that has just gone on sale priced from $92,990 drive-away. 2023 Roev electric Toyota HiLux.

Light over heat: UV-driven rhodium nanoparticles catalyze conversion of CO2 to methane

Green Car Congress

Duke University researchers have engineered rhodium nanoparticles that can harness the energy in ultraviolet light and use it to catalyze the conversion of carbon dioxide to methane, a key building block for many types of fuels. An open-access paper on the work is published in Nature Communications. —Zhang et al.

Elemental boron effective photothermocatalyst for the conversion of CO2 for fuels and chemicals

Green Car Congress

Researchers in Japan and China developed an efficient method for CO 2 reduction over elemental boron catalysts in the presence of only water and light irradiation through a photothermocatalytic process. A paper on their work is published in the journal Angewandte Chemie. When the sun shines on a surface, it is heated. —Jinhua Ye.

New mesocrystal photocatalyst enhances light-driven hydrogen production

Green Car Congress

When light is applied to photocatalysts, electrons and holes are produced on the surface of the catalyst; hydrogen is obtained when these electrons reduce the hydrogen ions in water. As a result, it has a more efficient conversion rate for producing hydrogen than conventional nanoparticulate photocatalysts.

Scientists develop method for direct conversion of methane to methanol or acetic acid under mild conditions

Green Car Congress

Researchers at Argonne National Laboratory, Tufts University and Oak Ridge National Laboratory have shown that mononuclear rhodium species, anchored on a zeolite or titanium dioxide support suspended in aqueous solution, can catalyze the direct conversion of methane to methanol and acetic acid using oxygen and carbon monoxide under mild conditions.

ICCT working paper highlights benefits of current and emerging light-duty diesel technology; “promising pathway for compliance”

Green Car Congress

Diesel vehicles have had a rough time penetrating the US light-duty vehicle market, reflecting outdated negative perceptions, higher fuel prices for diesel than for gasoline, the cost of complying with stringent US emission standards, and rapidly improving gasoline engines. —Isenstadt and German (2017).
