Argonne releases GREET 2020

Green Car Congress

Renewable natural gas and lactic acid production from wet waste feedstocks. The results show that both waste-derived RNG and LA production pathways bring significant GHG emission reduction benefits. These pathways include methanol derived from natural gas, flare gas, biomass, renewable natural gas, coal, and black liquor.

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

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

For power generation in the US, natural gas is commonly used in both simple-cycle natural gas turbines and combined-cycle natural gas turbines which use waste heat recovery to increase electrical generating efficiency. The share of conventional natural gas and shale gas was assumed to be 77% and 23%, respectively.

They also note that large-scale production of synthetic fuels or hydrogen from coal or gas offers the potential for GHG emissions reduction—but only if CO 2 can be captured and stored. Biogas, particularly from waste materials, has a very low GHG impact, whether the biogas is used to fuel cars or produce electricity.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The PHEV (Plug-in Hybrid Electric Vehicle), a subset of the electric car, combines a primary electric motor with a much smaller back-up engine fueled with a hydrocarbon/biofuel mix. (In In this paper PHEV refers solely to the long-range PHEV of 60 miles (100 km) electric-only range.) It is much more than that.
