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 3โ€“11% (5โ€“24ยข per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

Researchers report that SiC derived from ag waste can function as Li-ion anodes; competitive with silicon

Green Car Congress

Researchers at the University of Michigan, with colleagues from Michigan State University and Karlsruhe Institute of Technology (KIT) in Germany, report that high surface area silicon carbide (SiC) w/wo 13 wt. 6Li MAS NMR and XPS show no evidence of Li x Si, with Li preferring all-C environments supported by computational modeling.

U-M study finds crop-based biofuels associated with net increase in GHGs; falsifying the assumption of inherent carbon neutrality

Green Car Congress

A new study from University of Michigan researchers challenges the assumption that crop-based biofuels such as corn ethanol and biodiesel are inherently carbon-neutral—i.e., This assumption has been used in cap-and-trade programs and carbon taxes as promulgated to date, which address only fossil-derived CO 2 emissions.

GLBRC research review concludes cellulosic biofuels can benefit the environment if managed correctly

Green Car Congress

Carbon debt generated by stand establishment can be minimized by avoiding tillage and by avoiding lands with large C stores either above ground (such as forests) or below ground (such as wetlands). —Robertson et al.
