China team develops efficient multifunctional catalyst for conversion of CO2 to gasoline-range hydrocarbons

Green Car Congress

This catalyst exhibited 78% selectivity to C 5 -C 11 as well as low (4%) CH 4 at a CO 2 conversion of 22% under industrial relevant conditions. Moreover, the multifunctional catalyst exhibited a remarkable stability for 1,000 h on stream, showing potential to be a promising industrial catalyst for CO 2 conversion to liquid fuels.

Sandia-led team demonstrates two efficient hybrid biochemical routes for lignin conversion to value-added chemicals

Green Car Congress

A Sandia National Laboratories-led team has demonstrated two new routes to lignin conversion that combine the advantages of earlier methods while minimizing their drawbacks. Conversely, harsh chemicals can deconstruct lignin in hours or even minutes. Together, Singh reports, these chemicals have a combined market value of $255.7

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

The advancement could significantly boost the production of hydrogen from sunlight by using the cell to split water at a higher efficiency and lower cost than current photoelectrochemical approaches. The research is outlined in a paper in Nature Energy. Crisp, Jing Gu, Boris D. Chernomordik, Gregory F. Pach, Ashley R. Marshall, John A.

NREL shows graded catalytic-protective layer boosts longevity of high-efficiency photocathodes for renewable hydrogen

Green Car Congress

Researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL) have developed a method which boosts the longevity of high-efficiency photocathodes in photoelectrochemical water-splitting devices. A PEC cell absorbs sunlight and converts that energy into hydrogen and oxygen by splitting water molecules.

Cambridge team demonstrates light-driven photoreforming of unprocessed biomass to H2 at room temperature

Green Car Congress

Biomass conversion is one of the most affordable routes to generate sustainable H 2 , but this process requires the demanding chemical transformation of lignocellulose. In the interest of increasing the selectivity and efficiency of this conversion, it is possible to replace the thermal input with sunlight. Wakerley, Moritz F.

E-Waste is a Cybersecurity Problem, Too

Cars That Think

The conversation has been edited for length and clarity. If they get back into the land and water, it has very negative effects on the health of our vegetation, our animals, and our people. Five years of banging the drum, and thanks to this article, we were finally off to the races…comparatively. Comparatively.
