WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

Researchers at Washington University in St. The resulting biofuel, n -butanol, is a carbon-neutral fuel alternative that can be used in blends with diesel or gasoline. We hope that it can be a steppingstone for future sustainable solar fuel production. —Wei Bai. Ranaivoarisoa, T.O.,

Study Concludes That Large-Scale Transport of Ethanol Could Negate Its Economic and Environmental Benefits Compared to Gasoline

Green Car Congress

A new study by researchers at Carnegie Mellon University (CMU) concludes that the emissions associated with the transport of ethanol could negate its potential economic and environmental benefits compared to gasoline. L of E16, are an order of magnitude greater than equivalent transport costs for gasoline, at $0.003/L.

Study finds behavior-influencing policies remain critical for mass market success of low-carbon vehicles

Green Car Congress

Policies to entice consumers away from fossil-fuel powered vehicles and normalize low carbon, alternative-fuel alternatives, such as electric vehicles, are vital if the world is to significantly reduce transport sector carbon pure-emissions, according to a new study. Note the different scaling used in the graphs.

UC Davis report finds LCFS compliance costs may rise rapidly; recommends offsetting measures

Green Car Congress

The LCFS program calls for a 10% reduction in the carbon intensity of fuel sold in California over the next decade. Obligated parties are upstream producers and importers of gasoline and diesel fuel sold in the state. The program is agnostic as to which fuels can be used to meet the Standard. —Lade and Lin.

Researchers Propose New Method for Life Cycle Impact Assessment; Transportation Fuels as a Case Study

Green Car Congress

A pair of researchers from Purdue University and Rochester Institute of Technology are proposing a new approach to Lifecycle Impact Assessment (LCIA), designed to represent simultaneously multiple weights spaces and the sensitivity of the rank ordering to uncertain or multiple stakeholder values expressing different priorities.
