Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

Fuel-cycle SO 2 emissions of EVs compared to those of gasoline ICEVs and HEVs in China, current (left) and future (right). The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.

UC Davis researchers suggest we may be at the beginning of a real hydrogen transition in transportation

Green Car Congress

In many respects, hydrogen FCVs could offer features that are similar to today’s gasoline cars and are more challenging to achieve in battery-powered vehicles, including good performance, large vehicle size, refueling time of 3-5 minutes and a range of 300-400 miles. They find that perhaps 50,000 FCVs in a given region (e.g.

US National Research Council Report Finds Plug-in Hybrid Costs Likely to Remain High; Fleet Fuel Consumption and Carbon Emissions Benefits Will Be Modest for Decades

Green Car Congress

The PHEV-10, similar to the Prius Plug-In ( earlier post ) has a larger battery pack than an HEV to allow 10 miles of driving powered by electricity only and a gasoline engine that drives the wheels in parallel with the electric motor when power demand is high or the batteries are discharged.

Grail Engine Adopts Enerpulse Pulse Plugs for Forced Semi-Homogeneous Charged Compression Ignition in Concept Two-Stroke Engine

Green Car Congress

HCCI combustion can deliver a very efficient engine, potentially providing a 20% to 30% boost in gasoline engine efficiency without the NO x or PM emissions of a diesel. Unlike a spark ignition gas engine or diesel engine, HCCI produces a low-temperature, flameless release of energy throughout the entire combustion chamber. Matthew Riley.

GM Quantifies CO2 and Fuel Consumption Reductions Via E-REVs And PHEVs, As Compared To Conventional Hybrids

Green Car Congress

In the paper, the GM team broke down CO 2 and fuel consumption reduction potentials into several categories: The introduction of E-REVs and PHEVs to existing grids, displacing petroleum use; The influence of charging availability and consumer behavior on CO 2 reduction; Changes in power grid mix as well as vehicle stock; and.
