DOE: Life cycle GHG emissions for 2020 electric small SUV were half those of a conventional gasoline small SUV

Green Car Congress

Using current technologies, all evaluated biofuel, battery electric, and hydrogen fuel cell vehicle pathways offer significant C2G GHG emissions reduction compared to the current gasoline internal combustion engine vehicle. C2G emissions are a sum of WTW emissions and emissions associated with vehicle manufacturing.

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. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

PNNL team develops onboard fuel separation technology to enable octane-on-demand for improved fuel economy

Green Car Congress

Researchers at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) have developed an onboard separation system that could support increased fuel economy and lower greenhouse gas emissions as part of an octane-on-demand fuel-delivery system. Unfortunately, these engines exacerbate engine knock. —Allan Tuan.

Nacero transitioning unbuilt facility from low-carbon gasoline to SAF and LCAF; TOPSOE MTJet

Green Car Congress

Nacero will transition its current pre-construction, multi-billion USD facility in Penwell, Texas—designed to produce low carbon gasoline—to the production of sustainable aviation fuel (SAF) and lower carbon aviation fuel (LCAF). TIGAS efficiently produces high-value gasoline from natural gas, shale gas, or associated gas.

EIA: fuel economy standards drive down projected gasoline use; diesel use, product exports rise

Green Car Congress

In the US Energy Information Administration’s Annual Energy Outlook 2014 (AEO2014) Reference case, more-stringent vehicle fuel economy standards contribute to a decline in motor gasoline consumption through 2040. The Reference case projects an increase in VMT that, all else equal, would increase motor gasoline fuel consumption.

EIA: fuel economy improvements bring diminishing returns in fuel savings

Green Car Congress

Improving fuel economy exhibits diminishing returns in fuel savings, according to a brief analysis by the US Energy Information Administration (EIA). Similarly, the fuel and cost savings of improving fuel economy from 12 mpg to 15 mpg are the same as increasing from 30 mpg to 60 mpg.
