Researchers at the US Department of Energy’s Joint BioEnergy Institute (JBEI) have developed “bionic liquids”—ionic liquids derived from lignin and hemicellulose, two by-products of biofuel production from biorefineries. JBEI is a multi-institutional partnership led by Lawrence Berkeley National Laboratory (Berkeley Lab) that was established by the DOE Office of Science to accelerate the development of advanced, next-generation biofuels.
Ionic liquids show great promise for liberating fermentable sugars from lignocellulose and improving the economics of advanced biofuels. The concept of bionic liquids opens the door to realizing a closed-loop process for future lignocellulosic biorefineries, and has far-reaching economic impacts for other ionic liquid-based process technologies that currently use ionic liquids synthesized from petroleum sources, said Blake Simmons, a chemical engineer who is JBEI’s Chief Science and Technology Officer and heads JBEI’s Deconstruction Division.
Ethanol producer to integrate renewable diesel production from corn distiller oil
July 25, 2014
Ethanol producer East Kansas Agri-Energy LLC (EKAE) intends to integrate renewable diesel production at its ethanol plant in Garnett, Kansas. Renewable diesel will be made from the corn distillers oil (CDO) already produced at the plant along with other feedstocks purchased on the market. WB Services is the technology provider for the catalytic renewable diesel process.
Construction on the new facility will begin soon and will be complete in about 12 to 14 months. The plant will be able to produce three million gallons of hydrocarbon fuel per year, with the ability to double that capacity in the future. The plant currently produces some 40 million gallons of ethanol; 200,000 tons of the livestock feed distillers grains; and 5 million pounds of corn oil each year from more than 16 million bushels of locally-sourced corn.
California Energy Commission selects 11 advanced biofuels projects for $43.6M in awards
The California Energy Commission (CEC) has selected 11 biofuel projects projects—including gasoline substitutes, diesel substitutes and biomethane projects—for $43,633,421 in awards under a grant solicitation released in January for the development of new, or the modification of, existing California-based biofuel production facilities that can sustainably produce low carbon transportation fuels.
The grant solicitation had announced a total of $24 million available for projects funded by the solicitation; however, the Energy Commission, at its sole discretion, reserves the right to increase or reduce the amount of funds available.
Roadmap shows how to improve lignocellulosic biofuel biorefining with high-value products from isolated lignin
May 19, 2014
A new review article in the journal Science highlights emerging opportunities to increase the transformation of lignin to value-added products—i.e., lignin valorization. The resulting roadmap uses the integration of genetic engineering with analytical chemistry tools to tailor the structure of lignin and its isolation so it can be used for materials, chemicals and fuels, said lead author Arthur Ragauskas, a professor in the School of Chemistry and Biochemistry at the Georgia Institute of Technology.
Potential high-value products from isolated lignin include low-cost carbon fiber, engineering plastics and thermoplastic elastomers, polymeric foams and membranes, and a variety of fuels and chemicals—all currently sourced from petroleum. Each product stream, however, has its own distinct challenges.

A team from seven US universities and the Korea Institue of Science and Technology, led by George Huber, Professor of Chemical and Biological Engineering at the University of Wisconsin-Madison, has developed an integrated catalytic process for the conversion of whole biomass into drop-in aviation fuels with maximal carbon yields.
The researchers expect that in its current state, the proposed technology could deliver jet fuel-range liquid hydrocarbons for a minimum selling price of $4.75 per gallon—assuming nth commercial plant that produces 38 million gallons liquid fuels per year with a net present value of the 20 year biorefinery set to zero. Future improvements in this technology, including replacing precious metal catalysts by base metal catalysts and improving the recyclability of water streams, could reduce this cost to $2.88 per gallon.

Overall, Navigant forecasts that global retail sales of all liquid fuels for the road transportation sector will grow from more than $2.6 trillion in 2013 to more than $4.5 trillion in 2022 (73% growth).
DEINOVE produces ethanol at 9% titer with its optimized Deinococcus bacteria
January 16, 2014
DEINOVE, a technology company that designs, develops and markets a new generation of industrial processes based on optimized Deinococci bacteria, has produced ethanol at a titer of 9% via its fermentation of biomass sugars in 20L pre-industrial fermentors. In September 2012, the company had reported that its optimized strain of Deinococcus generated ethanol from wheat-based biomass with a titer of 3%. (Earlier post.)
The 9% content v/v (volume/volume)—equal to 7.2% wt/v (weight/volume)—exceeds the 5% alcohol content wt/v considered to be the threshold for industrial exploitation of a process for 2nd generation biofuels, the company said. The obtained performance is gradually approaching the maximum theoretical yield, the company added. The use of Deinoccoccus offers several benefits:
BAL scientists engineer yeast to produce ethanol from brown seaweed; brown seaweed biorefinery
December 03, 2013
An international team of researchers from Bio Architecture Labs, a synthetic biology and enzyme design company focused on the production of biofuels and biochemicals from macroalgae (seaweed) (earlier post), reports the development of a synthetic yeast platform based on Saccharomyces cerevisiae that can efficiently produce ethanol from brown seaweed; the paper is published in the journal Nature.
In January 2012, BAL scientists reported the engineering a strain of Eschericia coli that could break down and then ferment alginate—one of the most abundant sugars in brown algae, but a sugar that industrial microbes can’t metabolize—into ethanol. That paper was featured on the cover of the journal Science. (Earlier post.)

UCLA engineers develop new metabolic pathway for more efficient conversion of glucose into biofuels; possible 50% increase in biorefinery yield
October 01, 2013
Researchers at UCLA led by Dr. James Liao have created a new synthetic metabolic pathway for breaking down glucose that could lead to a 50% increase in the production of biofuels. The new pathway is intended to replace the natural metabolic pathway known as glycolysis, a series of chemical reactions that nearly all organisms use to convert sugars into the molecular precursors that cells need. The research is published in the journal Nature.
Native glycolytic pathways—a number of which have been discovered—oxidize the six-carbon sugar glucose into pyruvate and thence into two-carbon molecules known acetyl-CoA for either further oxidation or biosynthesis of cell constituents and products, including fatty acids, amino acids, isoprenoids and alcohols. However, the two remaining glucose carbons are lost as carbon dioxide.
KiOR seeks to double cellulosic fuels production at Columbus plant; $50M in from Khosla for Columbus II
September 26, 2013
Cellulosic gasoline and diesel company KiOR, Inc. is pursuing plans to double production capacity at its Columbus, Mississippi, facility through construction of a second facility incorporating KiOR’s commercially proven technology. KiOR estimates that the Columbus II project will cost approximately $225 million; will break ground within 90 days of it raising sufficient equity and debt capital to commence the project; and will take approximately 18 months to construct and start up.
Once completed with its latest technology improvements, KiOR expects that the Columbus II project will allow each Columbus facility to achieve greater yields, production capacity and feedstock flexibility than the original design basis for the existing Columbus facility, enabling KiOR to more quickly make progress towards its long-term goal of 92 gallons per bone dry ton of biomass.
OIG audit finds DOE has not achieved biorefinery goals despite 7 years and $603 million spent
September 13, 2013
An audit report released by the Department of Energy’s (DOE) Office of the Inspector General (OIG) found that despite more than 7 years of effort and the expenditure of about $603 million, DOE had not yet achieved its biorefinery development and production goals.
Specifically, the audit found, the mandate to demonstrate the commercial application of integrated biorefineries had not been met and DOE was not on target to meet its biofuels production capacity goal. Although DOE’s Bioenergy Technologies Office (BTO) reported meeting its goal to demonstrate the successful operation of three integrated biorefineries by 2012, OIG noted that these biorefineries were primarily much smaller pilot projects rather than commercial scale.
Gevo opens renewable paraxylene plant next to renewable jet fuel plant; bio-isobutanol biorefinery
August 27, 2013
Bio-isobutanol producer Gevo, Inc. held a ribbon-cutting ceremony for its demonstration-scale paraxylene (p-xylene) plant in Silsbee, Texas. The paraxylene facility is located adjacent to Gevo’s existing jet fuel plant in Silsbee, and establishes the site as a biorefinery that will serve the renewable chemicals and drop-in biofuels markets.
Gevo has been working with The Coca-Cola Company since 2011 (earlier post) to deliver a new production technology for renewable paraxylene, a key building block for producing fully renewable PET for beverage bottles. Research and Development support for this plant was provided by The Coca-Cola Company under a Joint Development Agreement.
