UC Davis ITS researchers take a detailed look at water consumption and withdrawal requirements for ethanol

Green Car Congress

Water consumption intensity of ethanol from corn grain and crop residue and the avoided/displaced water use credits assigned to coproducts: DGS and electricity. In their paper, Mishra and Yeh analyze the lifecycle water requirement consumption and withdrawal requirements of ethanol produced from corn and from crop residue.

Audi testing find e-ethanol and e-diesel produced by Joule often perform better than conventional counterparts

Green Car Congress

Joule’s Helioculture platform uses engineered microorganisms directly and continuously to convert sunlight and waste CO 2 into infrastructure-ready fuels, including ethanol and hydrocarbons (n-alkanes) that serve as the essential chemical building blocks for diesel. Audi is testing different blends of the e-fuels as well as 100% fuel.
