Chalmers team engineers synthetic enzymes for bio-production of fuel alternatives

Green Car Congress

In other words: We are now able to produce petrol and jet fuel alternatives in yeast cell factories,” he said. The researchers are now focusing on using the modified enzyme to build yeast cell factories for production of chemicals and fuels from glucose. —Zhu et al. —Zhiwei Zhu.

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

Green Car Congress

The resulting biofuel, n -butanol, is a carbon-neutral fuel alternative that can be used in blends with diesel or gasoline. —Arpita Bose, associate professor of biology in Arts & Sciences, and leader of the study. We hope that it can be a steppingstone for future sustainable solar fuel production.

Study finds renewable fuel mandates alone not likely to lower carbon intensity of biofuels; the importance of localized LCAs and optimized low carbon fuel standards

Green Car Congress

Localized differences in electrical generation, crude oil sources, biomass production practices, refinery efficiencies, and other parameters may cause the fuel carbon intensity (FCI) of specific fuel pathways to differ significantly from the national average. renewable fuel standards—and LCFSs. —Boies et al.

Study Concludes That Large-Scale Transport of Ethanol Could Negate Its Economic and Environmental Benefits Compared to Gasoline

Green Car Congress

Emissions from ethanol transport in the CMU study applied to ethanol life cycle emissions from other studies. A new study by researchers at Carnegie Mellon University (CMU) concludes that the emissions associated with the transport of ethanol could negate its potential economic and environmental benefits compared to gasoline.

MIT study concludes that absent climate policy, coal-to-liquids could account for around a third of global liquid fuels by 2050

Green Car Congress

Converting coal into liquid fuels is known to be more costly than current energy technologies, both in terms of production costs and the amount of greenhouse gases the process emits. Production of CTL has a large carbon footprint, releasing more than twice the lifecycle greenhouse gases of conventional petroleum fuels.
