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.

Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

That insight could also help the car industry make cleaner combustion engines. The industrial processes behind crude oil refineries and the inner-workings of gas-powered combustion engines can emit PAHs, which can form into toxic air pollutants such as soot. Zhao et al.

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. Louis have discovered a new way to train microbes to make n -butanol.
