Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. EH&E) and Adjunct Professor of Environmental Health at Harvard’s T.H. Scully et al.

Emissions Analytics argues that current Pareto-efficient solution for decarbonization would be hybrids, not BEVs, based on do-no-harm

Green Car Congress

On this basis, and of Pareto efficiency, Emissions Analytics argues, until battery-electric vehicles can reach certain performance characteristics, government and industry support should switch immediately from EVs to full hybrids to create maximum welfare. The test cycle was made up of five repeats of the EQUA cycle, totalling 741 km.

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.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. The researchers collected simulated rides provided by three fleets: gasoline-powered, and electric-powered with either 40 kWh or 60 kWh battery packs. Scott Institute for Energy Innovation.

National labs team delivers techno-economic analyses of H2 DRI scenarios for green steel

Green Car Congress

Yet, the lack of established process and business models defining “green steel” make it difficult to understand what the respective H 2 price has to be in order to be competitive with commercial state-of-the-art natural gas DRI. … per kg, while achieving a CO 2 emission reduction of 76% at the plant site. per kg H 2 or less.

FEV testing finds Transient Plasma ignition system increases fuel efficiency and decreases emissions

Green Car Congress

Data was collected with the stock ignition system with a representative ignition strategy, followed by comparison to a drop-in replacement with the TPS nanosecond pulsed power ignition system (coil and plug). The Toyota 2.5L engine was tested at FEV North America and results indicate improvements over the stock ignition system.
