In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario.

For instance, electricity generated from coal or natural gas is associated with higher carbon emissions, while renewable sources like wind or solar energy contribute negligible carbon pollution. The shift towards renewable energy sources further enhances the environmental benefits of EVs.

This is especially important for assessing the GHG emissions of PHEVs. For battery EVs, the GHG emissions for “fuel/electricity” production are dominated by the coal and natural gas used in electricity generation. BEVs powered by renewable electricity and FCEVs fueled by green hydrogen are the only two technology pathways that qualify.

In the new report, the authors observe that while a shift to renewable/low fossil carbon routes may potentially offer significant reductions in GHG, it also generally requires more total energy; i.e., the specific pathway is critical. Producing synthetic gas (SNG) from wind electricity (e.g.,

However, US coal shipments, which are primarily via rail, decline slightly. California’s Zero-Emission Vehicle regulation, which nine additional states have adopted, requires a minimum percentage of vehicle sales of BEV and PHEV. Freight rail ton-miles grow by 20% during the same period, led primarily by rising industrial output.

Developing technologies for the conversion of biomass and coal-to-liquid fuels. By 2035, cellulosic ethanol and/or coal-and-biomass-to-liquid (CBTL) fuels with carbon capture and storage could replace about 15% of current fuel consumption in the transportation sector (1.7–2.5 emissions, according to the report.

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. The lowest WTW energy demand and GHG emissions were achieved using electricity from waste incineration, biogas CHP, hydropower, wind power, and photovoltaic power.
