ACEEE report recommends steps toward international alignment of heavy-duty vehicle efficiency standards

Green Car Congress

Foundational steps toward such alignment would include a common set of test cycles and test payload weights, which would serve to define universal measures of vehicle performance. This in turn would permit a standardized calculation of cost-effectiveness of technology improvements as a function of regional conditions. Test cycles.

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

The cost of hydrogen—which varies widely depending on location, mode of production and supply, and natural gas prices—is important in determining how much hydroprocessing should be done before deoxygenation with the zeolite catalyst, the authors note. In comparison, increasing the H/C eff ratio of pyrolysis oil from 0 to 1.4

Tsinghua Researchers Find that Sugarcane Juice is a Good Fermentation Feedstock for Algal Biodiesel

Green Car Congress

Researchers at Tsinghua University in China have shown that sugarcane juice is a good feedstock for biodiesel production, when used to support the growth of the alga Chlorella protothecoides by heterotrophic fermentation. This new study investigated further improvements in algal oil yield, while minimizing the cost of fermentation.
