UC Davis team engineers cyanobacterium for enhanced direct production of 2,3-butanediol; design methods for exogenous chemical production

Green Car Congress

In a paper published in the Proceedings of the National Academy of Sciences (PNAS), they reported the production by their organism of 23BD from CO 2 reached 2.38 g/L—a significant increase for chemical production from exogenous pathways in cyanobacteria.

UC Davis process produces gasoline-range hydrocarbons from biomass-derived levulinic acid; field-to-tank yield of >60% claimed

Green Car Congress

GC-MS chromatogram of the liquid products obtained after hydrodeoxygenation of angelica lactone dimer. Considering that levulinic acid is available with more than 80% conversion from raw biomass, a field-to-tank yield of drop-in, cellulosic gasoline of more than 60% is possible, the researchers claimed.

Waste gasification company Sierra Energy closes $33M Series A funding; FastOx

Green Car Congress

The funding will help Sierra Energy further develop and commercialize its FastOx gasification technology, which converts virtually any waste into clean, renewable energy and fuels without burning. Sierra Energy was founded in Davis, California in 2004. Waste is fed into the top of the gasifier vessel through an airlock.

NREL process boosts production of ethanol from algae

Green Car Congress

Cost of algal biofuel production is still a major challenge and the Energy Department has made reducing the costs of both algae production and conversion of algal intermediates to fuels significant goals. In traditional processes, the algae produce lipids that get converted into fuels. Knoshaug, Ryan Davis, Lieve M.L.

Argonne LCA finds renewable diesel from algae fractionation has 63-68% lower GHG than petroleum diesel

Green Car Congress

In some algal biofuel production methods, lipids are extracted from algae and converted to renewable diesel, while the non-lipid components of the algae are converted to biogas. The biogas is used for renewable heat and electricity to power the conversion process of the lipids to renewable diesel. Pegallapati and Frank.

Caltech engineers devise new thermochemical cycle for water splitting for H2; recyclable, non-toxic, non-corrosive and at lower temperatures

Green Car Congress

Providing a possible new route to hydrogen-gas production, researchers at the California Institute of Technology (Caltech) have devised a new manganese-based thermochemical cycle with a highest operating temperature of 850?°C Davis’ first paper as a graduate student dealt with the sulfur-iodine low-temperature water-splitting cycle.).
