Report for the EC evaluates prospects for sugar-based platforms for biofuels and biochemicals
May 08, 2015
A comprehensive review of 94 potential pathways to biofuels and biochemicals via the sugar platform, prepared for the European Commission (DG ENER) by a team from E4tech, RE-CORD and Wageningen UR, finds that the global market value of the sugar platform is today of the order of $65 billion, with bioethanol (from sugar and starch crops) by far the dominant product in the market.
While several newer biofuel and biochemical routes show significant growth potential, only a few are currently crossing the valley of death between research and commercialization. Of ten case studies (the technologies being at least at TRL5) considered in detail, most can deliver significant greenhouse gas (GHG) savings and identical (or improved) physical properties, but at an added cost to fossil alternatives.
BIO: RFS policy instability has chilled advanced and cellulosic biofuel investments; $13.7B shortfall
May 04, 2015
EPA’s delays in rulemaking for the Renewable Fuel Standard (RFS) over the past two years have chilled necessary investment in advanced and cellulosic biofuels just as they reached commercial deployment. The industry has experienced an estimated $13.7-billion shortfall in investment as a result, according to a new analysis released by the Biotechnology Industry Organization (BIO).
To reach the 2015 RFS goal of producing 5.5 billion gallons of advanced biofuels (including 3 billion gallons of cellulosic and 2.5 billion gallons of advanced biofuel or biodiesel), Bio Economic Research Associates (bio-era) estimated the need for 110 operating plants requiring $20.34 billion dollars in cumulative investment. The research and advisory firm also estimated that more than $95 billion in cumulative capital investments would be needed by 2022 for construction of nearly 400 advanced biofuel biorefineries with the capacity to produce 23 billion gallons of advanced biofuel.
Battelle passes 1,000-hour milestone with continuous hydrotreatment process for bio-oil to fuels
April 27, 2015
Researchers at Battelle led by principal investigator Dr. Zia Abdullah have demonstrated the durability of a continuous hydrotreatment process that converts bio-oil from biomass pyrolysis into transportation and aviation fuels, meeting the longevity goals of a challenge from the United States Department of Energy’s (DOE) to make commercially viable transportation fuels from biomass pyrolysis.
Battelle, with its proprietary process (earlier post) and catalyst from Pacific Northwest National Laboratory (PNNL) successfully registered more than 1,200 hours of operation of the system. The end hydrocarbon products are 30% blendable with ASTM petroleum fuels. The Battelle team has set its sights on achieving the near-commercial standard of 4,000 hours in the near future; 4,000 hours represents about half a year of continuous operation, Abdullah noted.
Indian researchers propose fuel-chemicals-electricity cellulosic biomass biorefinery scheme
April 19, 2015
Researchers from the CSIR-Indian Institute of Petroleum are proposing a biorefinery scheme using lignocellulosic biomass feedstock (sugarcane bagasse) for the production of fuel (ethanol), chemicals (furfural), and energy (electricity). The proposed scheme could be integrated with existing sugar or paper mills, where the availability of biomass feedstock is in abundance as a means to address some of the cost and logistics issues, they suggest in their paper published in the ACS journal Energy & Fuels.
In their approach, they extract fermentable sugar components (xylose and glucose) from sugarcane bagasse employing acid hydrolysis and enzymatic saccharification; recovery and reuse of the enzyme is a process advantage. The pentose fraction is used for yeast biomass generation and furfural production. High-temperature fermentation of the hexose stream by the thermophilic yeast Kluyveromyces sp. IIPE453 with cell recycle produces ethanol with an overall yield of 88% ± 0.05% and a productivity of 0.76 ± 0.02 g/L h−1. A complete material balance on two consecutive process cycles, each starting with 1 kg of feedstock, resulted in an overall yield of 366 mL of ethanol, 149 g of furfural, and 0.30 kW of electricity.

New version of Argonne lifecycle model for water footprint of biofuels now includes cellulosic feedstocks
January 16, 2015
Argonne National Laboratory released the newest version (3.0) of the online tool Water Assessment for Transportation Energy Resources (WATER) this week. This latest version of WATER allows, for the first time, biofuels manufacturers to analyze water consumption associated with use of cellulosic feedstocks such as residue left from lumber production and other wood-based resources. The new tool also provides analysis down to the county level in the US for the first time.
WATER adopts a water footprint methodology, and contains extensive climate, land use, water resource, and process water data. Version 3.0 of WATER thus can help biofuels developers gain a detailed understanding of water consumption of various types of feedstocks, aiding development of sustainable fuels that will reduce impact on limited water resources.

U Wisc. scientists develop new method to convert lignin to simple chemicals under mild conditions
November 03, 2014
Researchers at the University of Wisconsin have disclosed a new method to convert lignin, an important component of biomass waste, into simple chemicals. Lignin, which accounts for nearly 30% of the organic carbon in the biosphere, is a complex material containing chains of six-carbon rings. These aromatics could be the basis for a sustainable supply of useful chemicals, but only if the chains of lignin can be broken down into the individual units. Lignin, however, is highly resistant to breakdown, especially in a cost-effective way.
Prof. Shannon Stahl and his colleagues developed, in work funded by the Great Lakes Bioenergy Research Center at UW-Madison, a method for the depolymerization of oxidized lignin under mild conditions in aqueous formic acid that results in more than 60 wt% yield of low-molecular-mass aromatics. A paper on the method is published in the journal Nature.

October 09, 2014
The US Department of Energy (DOE) will award up to $13.4 million for five projects to develop advanced biofuels and bioproducts that will help drive down the cost of producing gasoline, diesel, and jet fuel from biomass. These products not only will help reduce carbon emissions, but also advance the department’s work to enable the production of drop-in biofuel at $3 per gallon by 2022.
The research and development projects will focus on developing integrated processes for the production of advanced biofuels and chemicals. Two of these selections will address research efforts on the efficient conversion of biogas (a mixture of gases generated from the biological breakdown of organic material) to valuable products other than power.
Departments of the Navy, Energy and Agriculture award $210M in contracts for 3 drop-in fuel biorefineries; more than 100M gallons/year
September 20, 2014
The US Departments of Navy, Energy, and Agriculture have awarded contracts worth a combined $210 million to three companies—Emerald Biofuels, Fulcrum BioEnergy and Red Rock Biofuels—to construct and commission biorefineries capable of producing drop-in biofuels. In total, these projects are intended to produce more than 100 million gallons of military-grade fuel beginning in 2016 and 2017 at a price competitive with their petroleum counterparts.
The awards were made through the Department of Defense’s (DOD) Defense Production Act (DPA) of 1950, which was passed at the beginning of the Korean War to empower the President, among other things, with an array of authorities to shape national defense preparedness programs and to take appropriate steps to maintain and enhance the domestic industrial base. DPA has been re-authorized multiple times since then.

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.

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.
Study finds that optimized integrated catalytic processing of biomass could produce renewable jet fuel with selling price as low as $2.88/gallon
May 09, 2014
|Integrated processing of hardwood to renewable jet and chemicals. Click to enlarge.|
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.
