Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

is shown with both UK and French grid mixes. Renault recently made public the findings of an internal study, published first in October 2011, detailing and comparing the lifecycle assessments (LCAs) of the battery-electric and two internal combustion engined versions (gasoline and diesel) of the Renault Fluence.

Lifecycle analysis finds Fischer-Tropsch diesel from coal and biomass with CCS can use less fossil energy than petroleum diesel, with GHG close to or below zero

Green Car Congress

A new study by Michael Wang and Jeongwoo Han at Argonne National Laboratory and Xiaomin Xie at Shanghai Jiao Tong University assesses the effects of carbon capture and storage (CCS) technology and cellulosic biomass and coal co-feeding in Fischer-Tropsch (FT) plants on energy use and greenhouse gas (GHG) emissions of FT diesel (FTD).

IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

The IEA said that this reflects the continued domination of fossil fuels—particularly coal—in the energy mix and the slow uptake of other, lower-carbon supply technologies. Smart grids, for example, make it easier and cheaper to replace fossil-fired power with renewables without jeopardizing the reliability of the energy system.

CMU study finds that HEVs and PHEVs with small battery packs offer more emissions and oil displacement benefits per dollar spent than large pack PHEVs and BEVs; policy implications

Green Car Congress

Strategies to promote adoption of hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) with small battery packs offer more social benefits (i.e., In our base case, we assume average US values for emissions and damage valuation of electricity generation, oil refining, vehicle.

Renewable Energy Generation: Change is not a destination, just as hope is not a strategy, a lesson exported from Detroit

Green Car Congress

RPS policies as of March 2011. In contrast, China’s 12 th five-year plan, March 5, 2011, requires 11.4 In Germany, renewable electricity generation will be 35 percent by 2020, and 50 percent by 2050. Why then do we not have the same clarity of goal for the electricity generating industry here in the USA?

Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

Green Car Congress

The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand. The researchers also considered intermediate (20% electric-powered miles) electrification—halfway between the high and low.

ARB posts six new LCFS pathway applications for comment; new PFAD biodiesel approach

Green Car Congress

The LCFS requires oil producers, importers and other fuel providers gradually to reduce, on a full-fuel lifecycle basis, the carbon intensity (CI) of their transportation fuel mix (measured in gCO 2 e/MJ) by from 0.25% in 2011 to 10% by 2020. The baseline carbon intensity for gasoline in the LCFS lookup table is 99.18 Earlier post.)
