Study finds energy savings of PHEVs relative to HEVs dependent on charging coverage and daily VMT

Green Car Congress

A study based on a spatial and longitudinal travel dataset by a team from Lamar University, Iowa State University and Oak Ridge National Laboratory found that whether plug-in hybrids (PHEVs) have lower energy costs that conventional gasoline vehicles (CGVs) or hybrid-electric vehicles (HEVs) depends on charger coverage.

Simulations identify potential approach to reducing amount of rare earths required in permanent magnets

Green Car Congress

Pölten University of Applied Sciences in Austria have shown that rare earth permanent magnets may contain local deformations in the crystal lattice of the material, resulting in a weakening of the magnetic force of the material in these areas. superconductors in both wind generators and electrical transmission lines.

Harmonizing Low Carbon Fuel Standards

Green Car Congress

Eleven northeast and mid-Atlantic states are currently participating in the evaluation of a regional Clean Fuels Standard (CFS), which would lower the average carbon intensity of transportation fuels in the region and support the development and use of alternative fuels such as advanced biofuels, electricity, and natural gas.

Study finds removing corn residue for biofuel production can decrease soil organic carbon and increase CO2 emissions; may miss mandated 60% GHG reduction

Green Car Congress

Using corn crop residue to make ethanol and other biofuels reduces soil carbon and under some conditions can generate more greenhouse gases than gasoline, according to a major, multi-year study by a University of Nebraska-Lincoln team of researchers published in the journal Nature Climate Change. The uncompressed input data totalled ?3
