Georgia Tech life-cycle study finds TCO of medium-duty electric and diesel delivery trucks similar; electric life-cycle energy use and GHG lower than diesel

Green Car Congress

Life-cycle energy use and GHG emissions normalized with NYCC diesel case (8.06 They also found that the total costs of ownership (TCO) of the electric and diesel trucks are similar. Over an array of possible conditions, the median TCO of electric trucks is 22% less than that of diesel trucks on the NYCC. MJ/t·km and 0.63

Study concludes 20% synthetic diesel blend could reduce PM emissions in Beijing by ~19%

Green Car Congress

PM emissions from current vehicles in Beijing could be reduced by approximately 19% by simply blending 20% synthetic diesel with currently available diesel, according to a new study by Tsinghua University, the Desert Research Institute in Nevada and Greyrock Energy, a developer of gas-to-liquids technology.

EPA GHG Inventory shows US GHG down 1.7% y-o-y in 2019, down 13% from 2005

Green Car Congress

This decrease was driven largely by a decrease in emissions from fossil fuel combustion resulting from a decrease in total energy use in 2019 compared to 2018 and a continued shift from coal to natural gas and renewables in the electric power sector. from 2018 to 2019, and CO 2 emissions just from fossil fuel combustion decreased 2.7%

EPA: US GHG fell 0.5% y-o-y in 2017; power sector down by 4.2%, transportation up 1.21%

Green Car Congress

This decrease was largely driven by a decrease in emissions from fossil fuel combustion, which was a result of multiple factors including a continued shift from coal to natural gas and increased use of renewables in the electric power sector, and milder weather that contributed to less overall electricity use.

Georgia Tech study finds MD electric urban delivery trucks have cost advantages over diesel in some conditions; relative benefits depend on numerous factors

Green Car Congress

The study found that TCO for electric and diesel medium-duty urban delivery trucks were similar. Researchers at Georgia Tech have compared medium-duty (MD) electric and diesel urban delivery trucks in terms of life-cycle energy consumption, greenhouse gas (GHG) emissions, and total cost of ownership (TCO).

NREL/Chevron team characterizes chemical composition and properties of renewable diesels derived from FT, hydrotreating, and fermentation of sugar

Green Car Congress

A team from the US National Renewable Energy Laboratory (NREL) and Chevron Corporation has examined the chemical composition and properties of several diesel fuels and blendstocks derived from Fischer?Tropsch Thus, these fuels should have more similarities than differences regardless of feedstock or manufacturing process.
