Berkeley Lab scientists generate low-cost, hybrid thermoelectric materials

Green Car Congress

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have constructed a low-cost, nanoscale composite hybrid thermoelectric material by wrapping a polymer that conducts electricity around a nanorod of tellurium—a metal coupled with cadmium in today’s most cost-effective solar cells.

Genomatica has been producing BDO at pilot scale in 3,000 liter fermentations since the first half of 2010, and is moving to production at demonstration scale in 2011. Fermentation requires no organic solvent, and the water used is recycled. Greener reaction conditions: Kraton Performance Polymers, LLC, Houston, Texas.

ICCT study concludes no technical barriers to use of higher blends of ethanol

Green Car Congress

Theoretically, cars operating on higher ethanol blends than the design point could emit greater concentrations of pollutants in exhaust gas. In the cylinder where combustion takes place, the fuel evaporates before it is burned, and this evaporation helps cool off the air/fuel mixture and exhaust gas.

BIO Conference Highlights Emerging Range of Pathways to Drop-in Renewable Hydrocarbon Fuels

Green Car Congress

The following list of companies presenting their pathways to hydrocarbon fuels at the BIO conference is not exhaustive; indeed, other companies at the same conference could take their platforms, which they are currently targeting at the lower-volume, higher-value chemical molecule market, to produce higher-volume, lower value transportation fuels.
