DOE tool allows consumers to estimate localized upstream greenhouse gas emissions for EVs and PHEVs

Green Car Congress

The US Department of Energy (DOE) has published a Beyond Tailpipe Emissions Calculator that provides estimates of total greenhouse gas (GHG) emissions associated with driving an electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV), including emissions from the production of electricity used to power the vehicle.

Porsche simulates hydrogen V8 for virtual Nordschleife run; 440 kW, 261 km/h, near-zero NOx

Green Car Congress

We have therefore developed a hydrogen combustion engine that aims to match the power and torque of current high-performance gasoline engines as a concept study. liter eight-cylinder gasoline engine—or rather, its digital data set, since we conducted the entire study virtually using engine performance simulations.

“Charging Station” — Is That the Location or the “Charger”?

EV Adoption

If we didn’t have enough hurdles to electric vehicle adoption in the US, one of the challenges that drives me absolutely bonkers is the confusing and inconsistent use of charging terminology. To scale up EV adoption we need to increase consumer awareness and understanding of the “electric refueling” process. But nobody else cares. .

CMU study finds small battery PHEVs and gasoline hybrids the least-cost policy solution to reducing gasoline consumption

Green Car Congress

Comparison of current federal subsidy to base case assumptions showing lifetime fuel savings (HomeEve charging scenario). An EPA estimate based on the Chevy Volt’s reported efficiency is also included for comparison. Earlier post.). per gallon saved while subsidizing 16 kWh battery PHEVs at roughly $4.50

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

Green Car Congress

Renault’s comparison of the carbon footprint of EV and ICE vehicles over production, operation and end of life. The publication gives the opportunity for an “apples-to-apples” comparison between the environmental impacts of the two types of powertrains: same manufacturer, same model, same boundary conditions. Gasoline Fluence 16V.

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.

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.
