Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

WTW energy demand and GHG emissions for EV and PHEV drivetrains for various electricity sources; gasoline ICE vehicle is solid square, hybrid the hollow square. First, it considers the performance of both mature and novel hydrogen production processes, multiple electricity generation pathways and several alternative drivetrains.

EPA Trends on EVs and PHEVs; beginning of a “measurable and meaningful impact” on new vehicle fuel economy and emissions

Green Car Congress

The agency’s reasoning was that since alternative fuel vehicle production has generally been less than 0.1% of total vehicle production until very recently, the impact of excluding alternative fuel vehicles was negligible. —EPA 2014 Trends report. Alt fuel vehicle impact on OEMs. EPA Trends report.

EIA AEO2015 projects elimination of net US energy imports in 2020-2030 timeframe; transportation energy consumption drops

Green Car Congress

The Annual Energy Outlook 2015 (AEO2015) released today by the US Energy Information Administration (EIA) projects that US energy imports and exports will come into balance—a first since the 1950s—because of continued oil and natural gas production growth and slow growth in energy demand.

SwRI wins $20M EPA contract for emissions and fuel consumption testing, analytical services

Green Car Congress

When a vehicle is tested for emissions and fuel economy on a chassis dynamometer, the load from aerodynamic drag, friction, and tire losses associated with road operation must be simulated. First, actual on-road operation must be characterized, which is referred to as the road-load force specification.

Study suggests energy and GHG impacts of synthetic hydrocarbon fuels from CO2 are greater than impacts of existing hydrocarbon fuels

Green Car Congress

Synthetic fuel production from fuel-combustion-based energy and CO 2 (top) and from atmospheric CO 2 using solar electricity (bottom). GHG emissions of different liquid fuel production routes related to a functional unit of 1 MJ. R indicates reference alternatives not explicitly modeled in this study.

7 airlines sign letters of intent to negotiate purchase of biomass-derived jet fuel from Solena Fuels; up to 16M gallons of fuel per year

Green Car Congress

The core of Solena’s three-step solution is its patented Solena Plasma Gasification (SPG) technology, which is capable of producing a synthetic fuel gas (BioSynGas) from the thermal conversion of bio-based hydrocarbons. The third step upgrades the FT products into jet fuel.

CMU study concludes alt fuel vehicle incentives for OEMs result in increased fleet gasoline consumption and emissions

Green Car Congress

A study by researchers at Carnegie Mellon University has concluded that regulatory incentives for OEMs for alternative fuel vehicles (AFVs) intended to encourage a technology transition in the transportation fleet result in increased fleet-wide gasoline consumption and emissions. —Jenn et al. —Jenn et al. 5b02842.
