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.

Interim NREL Report on In-Use Azure Balance Gasoline Hybrids in FedEx Fleet Finds Substantially Lower Tailpipe Emissions, Similar Fuel Economy to Diesels

Green Car Congress

FedEx has deployed 20 gasoline hybrid electric vehicles (gHEVs) on parcel delivery routes in the Sacramento and Los Angeles areas. This hybridized, gasoline-fueled vehicle is equipped with a three-way catalyst, which results in very low tailpipe gaseous emissions. Barnitt, May 2010 ( NREL/TP-540-47693 ).
