The US Department of Agriculture (USDA) is investing \$26 million to build infrastructure to expand the availability of higher-blend renewable biofuels by 822 million gallons annually in 23 states. USDA is making the awards under the Higher Blends Infrastructure Incentive Program. The funding will help increase the use of biofuels... Read more →

A patented process for converting alcohol sourced from renewable or industrial waste gases into jet or diesel fuel is being scaled up at the US Department of Energy’s Pacific Northwest National Laboratory with the help of partners at Oregon State University and the carbon-recycling experts at LanzaTech. A single-step chemical... Read more →

## UNL study finds non-flex fuel vehicles can adapt to E30 gasoline without performance compromise; fuel efficiency comparable to E15

##### 09 August 2021

A team at the University of Nebraska-Lincoln has investigated the long-term adaptability and economic feasibility of non-flex-fuel vehicles—vehicles designed to use fuel blends containing 85% ethanol (E85) or less—to consume a 30% ethanol (E30) fuel blend. Their results indicated that although modest changes can be observed in the behavior of... Read more →

Oak Ridge National Laboratory researchers have developed a new catalyst for converting ethanol into C3+ olefins—the chemical building blocks for renewable jet fuel and diesel—that pushes selectivity to a record-high 88%, a more than 10% gain over their previously developed catalyst. (Earlier post.) A paper on the new work is... Read more →

The well-established, cost-competitive ethanol market provides an opportunity to shift the composition of jet fuel and other fuel products away from petroleum. In the first step of a multi-step ethanol-to-jet-fuel process earlier developed by DOE’s Oak Ridge National Laboratory (ORNL’s), a catalyst is used to convert ethanol into butene-rich C3+...

A new lifecycle analysis by researchers at Argonne National Laboratory has found that the carbon intensity of corn ethanol has decreased 23%—from 58 to 45 gCO2e/MJ—from 2005 to 2019. Their open-access paper is published in the journal Biofuels, Bioproducts and Biorefining. Carbon intensity (gCO2e/MJ undenatured ethanol) of corn ethanol without... Read more →

Startup ClearFlame Engine Technologies announced a partnership with Alto Ingredients, a leading producer of specialty alcohols and essential ingredients, to conduct pilot demonstrations of ClearFlame’s solution for diesel engines using low-cost ethanol in Class 8 trucks. ClearFlame will provide Alto with a Class VIII truck retrofitted with a 500hp heavy-duty... Read more →

Researchers in Mexico have used a genetically engineered Escherichia coli to scale-up the co-production of hydrogen (H2) and ethanol (EtOH) using hemicellulosic hydrolysates from wheat straw pretreated (WSP) as substrate from a 0.01 to 10 L process. A paper on their work is published in the journal Fuel. Co-production of... Read more →

## Bosch, Shell, and Volkswagen develop renewable gasoline with 20% lower CO2; rollout of Blue Gasoline this year

##### 04 May 2021

Following on the introduction of R33 Blue Diesel (earlier post), Bosch, Shell, and Volkswagen have now developed a low-carbon gasoline. The new fuel, called Blue Gasoline, similarly contains up to 33% renewables, ensuring a well-to-wheel reduction in carbon emissions of at least 20% per kilometer driven. This means a fleet...
