Study estimates fuel economy improvements to US light-duty vehicles from 1975–2018 saved 2T gallons of fuel, 17B tons of CO2

Green Car Congress

A team from the University of Tennessee and the National Renewable Energy Laboratory (NREL) has the fuel savings due to fuel economy improvements over the past 43 years amount to approximately two trillion gallons of gasoline. gasoline demand would have put upward pressure on world oil prices.

Amyris renewable jet fuel receives regulatory approval in Brazil for blends up to 10%

Green Car Congress

Brazil’s fuels regulator, ANP, has cleared the way for the commercialization in Brazil of Amyris renewable jet fuel in blends of up to 10%. In the ES&T study base case, the researchers calculated a “rather optimistic” GHG footprint of 8.5g That paper is published in the ACS journal Environmental Science & Technology. Earlier post.).

PNAS study finds Vertimass CADO efficient way to convert ethanol to biohydrocarbons; 40 to 96% reduction in GHGs, based on feedstock

Green Car Congress

Increased oil prices or current production incentives make Vertimass fuel cost competitive, and CADO-derived hydrocarbon blendstocks pass on greenhouse gas emission reductions of the ethanol feedstock. GJ today with the potential to drop to $1.44/GJ GJ in the near future. —Pahola Thathiana Benavides.

Study: Kerry-Lieberman Bill Would Cut US Oil Imports By Up to 40% Below Current Levels

Green Car Congress

A new study by the Peterson Institute for International Economics concluded that the Kerry-Lieberman “American Power Act”—the energy and climate change legislation recently introduced in the Senate ( earlier post )—would reduced US oil imports by 33-40% below current levels and by 9-19% below projected business-as-usual levels by 2030.

Sandia study finds meeting RFS2 requirements unlikely without stronger enforcement mechanism; the importance of drop-in biofuels

Green Car Congress

The Sandia researchers showed that the key to meeting the RFS2 targets is the fuel price differential between E85 fuel and conventional gasoline (low ethanol blends), so that E85 owners refuel with E85 whenever possible. The Sandia study examines the set of circumstances under which the RFS2 mandate might be satisfied. Barter, Dawn K.

Comprehensive modeling study finds electric drive vehicle deployment has little observed effect on US system-wide emissions

Green Car Congress

The results of a new, comprehensive modeling study characterizing light-duty electric drive vehicle (EDV) deployment in the US over 108 discrete scenarios do not demonstrate a clear and consistent trend toward lower system-wide emissions of CO 2 , SO 2 , and NO x as EDV deployment increases.

Stanford, UC Santa Cruz study explores ramifications of demand-driven peak to conventional oil

Green Car Congress

In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).
