Researchers show mixotrophic fermentation process improves carbon conversion, boosting yields and reducing CO2

Green Car Congress

Consequently, first and second generation bioproduct manufacturing processes are economically challenged, particularly in light of recent low oil prices. One way to mitigate high feedstock cost is to maximize conversion into the bioproduct of interest. In this study, researchers tested how C. Jones, Alan G. Fast, Ellinor D.

Purdue analysis finds H2Bioil biofuel could be cost-competitive when crude is between $99–$116/barrel

Green Car Congress

Their analysis is published in the journal Biomass Conversion and Biorefinery. H 2 Bioil is created when biomass, such as switchgrass or corn stover, is heated rapidly to about 500 °C in the presence of pressurized hydrogen. The conversion process was created in the lab of Rakesh Agrawal, Purdue’s Winthrop E.

PNAS study finds Vertimass CADO efficient way to convert ethanol to biohydrocarbons; 40 to 96% reduction in GHGs, based on feedstock

Green Car Congress

Unlike prior processes for converting alcohols into hydrocarbons with multiple steps for dehydration, oligomerization, and hydrogenation, the Vertimass consolidated alcohol dehydration and oligomerization (CADO) conversion is accomplished in a single reactor system using a metal exchanged zeolite catalyst. GJ in the near future.

Startup Siluria Technologies developing novel bio-templated catalysts for economic direct conversion of methane to ethylene; potential for transportation fuels

Green Car Congress

It’s a robust technology, but you have to pay the oil price, and if you have to burn an awful lot of heat in order to enable that endothermic chemistry, if you were to care about the energy footprint of this, it’s the three pounds of CO 2 produced to make one pound of polyethylene. in a 1997 paper in Science.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil. by Brian J.

RAND study concludes use of alternative fuels by US military would convey no direct military benefit; recommends energy efficiency instead

Green Car Congress

Specific topics included: Opportunities to produce alternative fuels in a way that reduces lifecycle greenhouse gas emissions, including the use of clean energy alternatives such as nuclear, solar, and wind energies for powering the conversion processes. For the near- and mid-term alternative fuel options (i.e.,
