Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). coal, oil, natural gas, and biomass). Winter O 3 increases due to reduced loss via traffic NO x. Winter while PM 2.5

Lux Research: cost of electrofuels remains far from viable

Green Car Congress

The cost of electrofuels—fuels produced by catalyst-based systems for light capture, water electrolysis, and catalytic conversion of carbon dioxide and hydrogen to liquid fuels—remains far away from viable, according to a new analysis by Lux Research. Hydrogen-to-fuels.

Monash team proposes roadmap to renewable ammonia economy; 3 generations of technology

Green Car Congress

Generation 3 avoids the need for the Haber-Bosch process entirely by direct electrochemical conversion of N 2 to NH 3. The process generates H 2 from natural gas or coal through steam reforming and combines it with N 2 , which has been separated from air by a cryogenic process, to form NH 3.

Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

Hydrogen production pathways include low- and high-temperature electrolysis; solar thermochemical disassociation; photobiological splitting (four pathways: direct and indirect biophotolysis using hydrogenase and nitrogenase); gasification (coal, biomass); steam reforming (methane, ethanol); and partial oxidation. —Yazdanie et al.

SGH2 building largest green hydrogen production facility in California; gasification of waste into H2

Green Car Congress

SGH2’s gasification process uses a plasma-enhanced thermal catalytic conversion process optimized with oxygen-enriched gas. Producers of so-called blue, gray and brown hydrogen use either fossil fuels (natural gas or coal) or low-temperature gasification (.

Rice team develops plasmonic photocatalyst for one-step light-driven conversion of H2S to hydrogen and sulfur

Green Car Congress

An illustration of the light-powered, one-step remediation process for hydrogen sulfide gas made possible by a gold photocatalyst created at Rice University. Each island was a gold nanoparticle about 10 billionths of a meter across that would interact strongly with a specific wavelength of visible light. —Naomi Halas.
