Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

Phil Ansell, an aerospace engineer at the University of Illinois Urbana-Champaign, modeled the life cycle carbon dioxide equivalent emissions of liquid hydrogen production required to meet the fuel needs of Chicago’s O’Hare International Airport (ORD) with today’s electric grid mix. Ansell presented his findings at AIAA Aviation 2023 in June.

New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

Researchers in Canada have demonstrated a new photochemical diode artificial photosynthesis system that can enable efficient, unassisted overall pure water splitting without using any sacrificial reagent. overall water splitting reaction. The device could also be reconfigured to turn carbon dioxide back into fuel.

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

Researchers at the University of Michigan, McGill University and McMaster University have developed a binary copper?iron The researchers think that it could be recycling smokestack carbon dioxide into clean-burning fuel within 5-10 years. Turning carbon dioxide into methane is a very difficult process. Image credit: Baowen Zhou.
