MIT/UC Davis professors challenge claims that ethanol production decreased gasoline prices in 2010 and 2011

Green Car Congress

These trends make the empirical analysis extremely sensitive to model specification; however, we find that empirical models that are most consistent with economic and statistical theory suggest effects that are near zero and statistically insignificant. and statistically insignificant. t margin for oil refiners.

Argonne Study Examines Impact of Real World Drive Cycles on Efficiency and Cost of Different PHEV Configurations

Green Car Congress

For drive cycles, the Argonne team used the Kansas City data collected in 2005 by the US EPA, which instrumented more than 100 drivers and collected their driving statistics for one day. Cost benefit analysis. Based on the results, Argonne also modeled out the cost-benefit of the different configurations. Aymeric Rousseau.

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

Green Car Congress

C and pressures above 200 bar to be facile, and therefore the capital cost of plant and equipment is substantial. Modern H-B plants produce ammonia at an energy cost of at least 8 MWh tonne -1. The reaction between N 2 and H 2 requires temperatures in excess of 400 ?C Ammonia production is currently responsible for ~1.0% Generation 2.
