Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

New catalyst improves conversion of CO2 to syngas

Green Car Congress

Researchers from the University of Illinois at Chicago (UIC) have identified molybdenum disulfide as a promising cost-effective substitute for noble metal catalysts for the electrochemical reduction of carbon dioxide. In other chemical-reduction systems, the only reaction product is carbon monoxide. —Mohammad Asadi.

Argonne team finds copper cluster catalyst effective for low-pressure conversion of CO2 to methanol with high activity

Green Car Congress

Researchers at Argonne National Laboratory have identified a new material to catalyze the conversion of CO 2 via hydrogenation to methanol (CH 3 OH): size-selected Cu 4 clusters—clusters of four copper atoms each, called tetramers—supported on Al 2 O 3 thin films.

NREL develops novel method to produce renewable acrylonitrile; carbon fibers from renewable biomass

Green Car Congress

Most importantly for this project, acrylonitrile is also the primary building block in carbon fiber composites, which are used for lightweighting applications in automotive and air transportation. —NREL Associate Laboratory Director Adam Bratis and principal investigator of the NREL-led Renewable Carbon Fiber Consortium.

Study concludes permanent loss of peatlands in open-pit oil sands mining adds significantly to carbon burden of oil sands production

Green Car Congress

Researchers at the University of Alberta (Canada) have quantified the transformation of the boreal landscape by open-pit oil sands mining in Alberta, Canada to evaluate its effect on carbon storage and sequestration. million metric tons of stored carbon. Converting from units of carbon to CO 2 equivalents, this is between 41.8

Stanford researchers develop copper-based catalyst that produces ethanol from CO at room temperature; potential for closed-loop CO2-to-fuel process

Green Car Congress

Researchers at Stanford University have developed a nanocrystalline copper material that produces multi-carbon oxygenates (ethanol, acetate and n-propanol) with up to 57% Faraday efficiency at modest potentials (–0.25?volts 57% of the electric current went into producing these two compounds from carbon monoxide). volts to –0.5?volts

U Chicago, MIT study suggests ongoing use of fossil fuels absent new carbon taxes

Green Car Congress

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. We need both a policy like a carbon tax and to put more R&D money into renewables.
