Lux: Despite softness in utilization, global biofuels capacity to grow to 61.4 BGY in 2018; driven by novel fuels and feedstocks

August 31, 2015

The global biofuels industry averaged 68% in utilization rate from 2005 to 2014, reached a high of 80.9% in 2007, dropped to a low of 56.9% in 2012, and climbed slightly back to 60.4% in 2014. Despite the still apparent softness in capacity utilization, and the on-going softness in fossil fuel prices, global biofuels capacity will continue to grow from 55.1 billion gallons per year (BGY) to 61.4 BGY in 2018, according to a forecast by Lux Research. However, Lux predicts, growth between now and 2018 will not be a continuation of current course.

While ethanol and biodiesel will continue to dominate in absolute terms, these will grow at only a 1.5% CAGR through 2018. Novel fuels and feedstocks will drive the biofuels industry forward at a much more rapid 17% and 22% CAGRs through 2018, respectively.

Researchers propose 2nd law of thermodynamics-based process to select and develop microorganisms for optimal biofuel production

August 17, 2015

Researchers at the University of Maryland are proposing a new process to isolate and to direct the evolution of microorganisms that convert cellulosic biomass or gaseous CO2 and H2 to biofuels such as ethanol, 1-butanol, butane, or hexane (among others).

The approach is based on the theory that fermentation systems drive toward thermodynamic equilibrium. Physical chemists, observe Richard Kohn and Seon-Woo Kim, both of the Department of Animal and Avian Sciences, in their paper published in the Journal of Theoretical Biology, have understood that all chemical reactions are controlled by either thermodynamic or kinetic mechanisms. With thermodynamic control, the feasibility of reactions and the availability of pathway branches depend on the second law of thermodynamics. This law governs whether or not a reaction can proceed spontaneously in the forward direction based on the concentrations of reactants and products.

U Georgia team discovers tungsten in novel bacterial enzyme; potential for cellulosic biofuels

August 16, 2015

A team at the University of Georgia, Athens led by Distinguished Research Professor Michael Adams has discovered tungsten in what appears to be a novel enzyme in the biomass-degrading thermophilic bacterium Caldicellulosiruptor bescii. Tungsten is exceptionally rare in biological systems.

The researchers hypothesized that this new tungstoenzyme plays a key role in C. bescii’s primary metabolism, and its ability to convert plant biomass to simple fermentable sugars. This discovery could ultimately lead to commercially viable conversion of cellulosic biomass to fuels and chemical feedstocks. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

DOE BESC engineered microbe improves biobutanol yield from cellulose by a factor of 10

August 14, 2015

Researchers at the US Department of Energy’s (DOE’s) BioEnergy Science Center (BESC) have engineered a microbe that improves isobutanol yields from cellulose by a factor of 10. The work, published in the journal Metabolic Engineering, builds on results from 2011 in which researchers reported on the first genetically engineered microbe to produce isobutanol directly from cellulose. (Earlier post.)

Isobutanol is attractive because its energy density and octane values are closer to those of gasoline; it is useful not only as a direct replacement for gasoline but also as a chemical feedstock for a variety of products. For example, isobutanol can be chemically upgraded into a hydrocarbon equivalent for jet fuel.

JRC: Increased use of renewables results in growing GHG emission savings in the EU; transport contribution only 5%

August 07, 2015

Greenhouse gasses (GHG) emission savings due to final renewable energy consumption in electricity; cooling/heating; and transport sectors rose at a compound annual growth rate of 8.8% from 2009 to 2012, confirming renewables’ potential in climate change mitigation, according to a new report by the Joint Research Centre (JRC), the European Commission’s in-house science service. Nearly two thirds of the total savings came from renewable energy development in Germany, Sweden, France, Italy and Spain.

The report assesses data on the use of renewable energy, submitted by EU Member States every two years, as required by EU legislation on renewable energy. The report estimates that in 2012, when total GHG emissions reached the equivalent of 4546 Mt CO₂, the deployment of all renewables in the EU avoided the equivalent of 716 Mt CO₂ emissions. According to the report, the highest contribution by renewables in climate change mitigation in the EU in 2012 came from renewable electricity, which covered 64% of the savings, due to high penetration of wind and solar power, followed by renewable heating and cooling (31%) and renewable transport (5%).

Researchers engineer first low-methane-emission, high-starch rice; benefits for GHG control, food and bioenergy

July 30, 2015

Rice—the staple food for more than half of the world’s population—is one of the largest manmade sources of atmospheric methane, a potent greenhouse gas. Now, however, with the addition of a single gene from barley (SUSIBA2), a team of researchers in China, Sweden and the US has engineered a strain of rice—now named SUSIBA2—that can be cultivated to emit virtually no methane from its paddies during growth.

The new strain also delivers much more of the plant’s desired properties, such as starch for a richer food source and biomass for energy production. SUSIBA2 rice is the first high-starch, low-methane rice that could offer a significant and sustainable solution. A paper on the work is published in the journal Nature.

Argonne researchers developing multifunctional farm landscapes balancing economy, bioenergy and environment

July 08, 2015

In collaboration with the farming community of the Indian Creek Watershed in central Illinois, researchers from Argonne National Laboratory (ANL) are finding ways to meet three agrarian land management objectives simultaneously: maximizing a farmer’s production; growing feedstock for bioenergy; and protecting the environment.

Through careful data collection and modeling at a cornfield in Fairbury, the Argonne team found that achieving these goals—which might under some conditions be mutually exclusive—requires a multifunctional landscape. Such a landscape is one where resources are allocated efficiently and crops are situated in their ideal soil and landscape position. As an example, planting bioenergy crops such as willows or switchgrass in rows where commodity crops are having difficulty growing could both provide biomass feedstock and also limit the runoff of nitrogen fertilizer into waterways—all without hurting a farmer’s profits.

BioMim project seeks to mimic chemistry of brown rot fungus to improve biorefining

July 07, 2015

BioMim, a newly-launched $4 million, four-year project funded by the Research Council of Norway with industrial partners Borregaard and Kebony, is seeking to mimic the chemistry of the brown rot fungus to improve biorefining processes. Specifically, the international team of researchers will seek to utilize the brown-rot fungi’s unique mechanisms to remove biomass components in cell walls, creating much improved access for an optimized enzyme system.

The BioMim project is combining two processes. The first is a technology developed by Virginia Tech Professor Barry Goodell that borrows from the processes used by brown rot fungi that are commonly found breaking down woody debris on the forest floor. The resulting catalytic process for freeing cellulose from lignin has now been demonstrated at pilot scale. The BioMim team will expand on this technology and explore how it can be used efficiently in large-scale biorefineries.

Study finds perennial biofuel crops’ water consumption similar to corn

A study by a team from the Great Lakes Bioenergy Research Center (GLBRC) has found that perennial biofuel crops’ evapotranspiration does not differ greatly from corn. Evapotranspiration (ET) refers to the sum total of water lost while the plant is growing, either from evaporation through the plant stem itself (a process called “transpiration”), or from water evaporated off of the plant’s leaves or the ground.

The study, led by GLBRC scientist and Michigan State University professor of ecosystem ecology Stephen Hamilton, is the first multi-year effort to compare the water use of conventional corn crops to the perennial cropping systems of switchgrass, miscanthus, native grasses, restored prairies, and hybrid poplar trees. An open access paper on the work is published in the journal Environmental Research Letters.

Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

July 03, 2015

A study by researchers from the University of Wisconsin-Madison and a Michigan State University colleague has concluded that even with a relatively high rate of electrification of the US light-duty fleet (40% of vehicle miles traveled and 26% by fuel), an 80% reduction in greenhouse gases by 2050 relative to 1990 can only be achieved with significant quantities of low-carbon liquid fuel. The paper is published in the ACS journal Environmental Science & Technology.

For the study, the researchers benchmarked 27 scenarios against a 50% petroleum-reduction target and an 80% GHG-reduction target. They found that with high rates of electrification (40% of miles traveled) the petroleum-reduction benchmark could be satisfied, even with high travel demand growth. The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand.

EBI ketone condensation process for drop-in jet fuel or lubricant base oil from biomass; up to 80% lifecycle GHG savings

June 16, 2015

Researchers at the Energy Biosciences Institute (EBI), a partnership led by the University of California (UC) Berkeley that includes Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of Illinois at Urbana-Champaign, and BP, have developed a new method for producing drop-in aviation fuel as well as automotive lubricant base oils from sugarcane biomass. The strategy behind the process could also be applied to biomass from other non-food plants and agricultural waste that are fermented by genetically engineered microbes, the researchers said.

The catalytic process, described in an open-access paper in the Proceedings of the National Academy of Sciences (PNAS), selectively upgrades alkyl methyl ketones derived from sugarcane biomass into trimer condensates with better than 95% yields. These condensates are then hydro-deoxygenated into a new class of cycloalkane compounds that contain a cyclohexane ring and a quaternary carbon atom. These cycloalkane compounds can be tailored for the production of either jet fuel, or automotive lubricant base oils, resulting in products with superior cold-flow properties, density and viscosity that could achieve net life-cycle greenhouse gas savings of up to 80%, depending upon the optimization conditions.

EPA proposes volume requirements for Renewable Fuel Standard for 2014-2016

May 29, 2015

Adhering to a schedule in a proposed consent decree (earlier post), the US Environmental Protection Agency (EPA) announced its long-awaited proposed volume requirements (renewable volume obligations, RVO) (earlier post) under the Renewable Fuel Standard (RFS) program for the years 2014, 2015 and 2016, and also proposed volume requirements for biomass-based diesel for 2017. The period for public input and comment on the proposal will be open until 27 July. EPA says it will finalize the volume standards in this rule by 30 November.

EPA is proposing to establish the 2014 standards at levels that reflect the actual amount of domestic biofuel used in that year; the standards for 2015 and 2016 (and 2017 for biodiesel) increase steadily over time, with the most aggressive growth projected for the problematic area of cellulosic biofuels: from 33 million gallons in 2014 to 206 million gallons in 2016.

Global Bioenergies and Cristal Union form JV to produce renewable isobutene

May 21, 2015

Global Bioenergies, a developer of one-step fermentation processes for the direct and cost-efficient transformation of renewable resources into light olefins, and Cristal Union, the 4th largest European beet producer, have formed IBN-One, a joint venture to build and operate the first plant in France converting renewable resources into isobutene.

Global Bioenergies has engineered an initial series of bacterial strains that can produce light olefins via the fermentation of sugars. The process is designed to be used downstream from multiple sugar production pathways: sugar, starch and cellulose. The process can thus be used with cellulosic biomass, following pretreatment and hydrolysis. The company has targeted renewable isobutene as its first product. (Earlier post.)

Kyoto team develops two-stage process for direct liquefaction of low-rank coal and biomass under mild conditions

May 11, 2015

Researchers at Kyoto University in Japan have proposed a novel two-stage process to convert low-rank coals or biomass wastes under mild conditions to high-quality liquid fuel. A paper describing the process, which combines a degradative solvent extraction method they had developed earlier with the liquefaction of the resulting soluble, appears in the ACS journal Energy & Fuels.

One of the issues hampering the development of direct liquefaction of low-grade carbonaceous resources—such as low-rank coals and biomass wastes—to produce liquid fuel is their oxygen content. In low rank coals, cross-linking reactions among oxygen functional groups form large-molecular-weight compounds at temperatures lower than the liquefaction temperature; the oxygen-functional-group-derived cross-links may change to stronger carbon−carbon covalent linkages, suppressing the formation of light hydrocarbons.

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.

Aspergillus carbonarius. Source: JGI MycoCosm. Click to enlarge.

Researchers at Washington State University have engineered the filamentous fungus Aspergillus carbonarius ITEM 5010 to produce jet-range hydrocarbons directly from biomass. The researchers hope the work, reported in the journal Fungal Biology, leads to economically viable production of aviation biofuels in the next five years.

The team led by Birgitte Ahring, director and Battelle distinguished professor of the Bioproducts, Sciences and Engineering Laboratory at WSU Tri-cities, found that the production of hydrocarbons was dependent on the type of media used. Therefore, they tested ten different carbon sources (oatmeal, wheat bran, glucose, carboxymethyl cellulose, avicel, xylan, corn stover, switch grass, pretreated corn stover, and pretreated switch grass) to identify the maximum number and quantity of hydrocarbons produced.

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.

European Parliament votes to cap crop-derived biofuels at 7% of transport energy consumption by 2020

May 01, 2015

The European Parliament approved a draft law to to cap crop-derived biofuel consumption and accelerate the shift to alternative sources. Member states must enact the legislation by 2017.

Current legislation requires EU member states to ensure that renewable energy accounts for at least 10% of energy consumption in transport by 2020. The new law says that first-generation biofuels (from crops grown on agricultural land) should account for no more than 7% of energy consumption in transport by 2020. The intent of the new law is to cut greenhouse gas (GHG) emissions caused by the growing use of farm land for biofuel crops.

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.

First integrated assessment of quality and yield of hydrocarbon blendstocks via biomass fast pyrolysis and hydrotreating

Researchers from three US national labs—Pacific Northwest National Laboratory (PNNL), Idaho National Laboratory (INL) and the National Renewable Energy Laboratory (NREL)—have performed the first, fully integrated assessment of the quality and yield of common feedstocks from the field to hydrocarbon blendstock production using the fast pyrolysis-hydrotreating pathway. A paper describing the results is published in the ACS journal Energy & Fuels.

Among their findings was that the compositional parameters of the biomass feedstock affects both the bio-oil generated by fast pyrolysis as well as the final quantity and quality of the upgraded fuel blendstock. While some feedstocks—such as tulip poplar—generate a high yield of bio-oil, the bio-oil does not necessarily exhibit a high yield in the hydrotreater. Thus, the product yields and qualities of both fast pyrolysis and hydrotreating must be considered in comparing the conversion performance of different biofuel feedstock materials.

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.

Virginia Tech team engineers optimized synthetic enzymatic pathway for high-yield production of H2 directly from biomass

April 07, 2015

A team of Virginia Tech researchers and colleagues has demonstrated the complete conversion of glucose and xylose from pretreated plant biomass to H2 and CO2 based on an in vitro synthetic enzymatic pathway crafted from more than 10 purified enzymes. Glucose and xylose were simultaneously converted to H2 with a yield of two H2 per carbon, the maximum possible yield.

The researchers used a nonlinear kinetic model fitted with experimental data to identify the enzymes that had the greatest impact on reaction rate and yield. After optimizing enzyme loadings using this model, volumetric H2 productivity was increased 3-fold to 32 mmol H2⋅L−1⋅h−1. The productivity was further enhanced to 54 mmol H2⋅L−1⋅h−1 by increasing reaction temperature, substrate, and enzyme concentrations—an increase of 67-fold compared with the initial studies using this method.

Global investment in renewable power reached $270.2B in 2014, ~17% up from 2013; biofuel investment fell 8% to 10-year low

April 06, 2015

Global investment in renewable power and fuels (excluding large hydro-electric projects) was $270.2 billion in 2014, nearly 17% higher than the previous year, according to the latest edition of an annual report commissioned by the United Nations Environment Program’s (UNEP) Division of Technology, Industry and Economic (DTIE) in cooperation with Frankfurt School-UNEP Collaborating Centre for Climate & Sustainable Energy Finance and produced in collaboration with Bloomberg New Energy Finance.

This marked the first annual increase in dollar commitments to renewables—excluding large hydro—for three years, and brought the total up to just 3% below the all-time record of $278.8 billion set in 2011. The increase reflected several influences, according to the report, including a boom in solar installations in China and Japan—totalling $74.9 billion between those two countries—and a record $18.6 billion of final investment decisions on offshore wind projects in Europe.

A*STAR team combines fungal culture and acid hydrolyses for cost-effective production of fermentable sugars from palm oil waste

March 16, 2015

Researchers from A*STAR in Singapore have developed a fungal culture for use in a cheap and efficient method to transform waste oil palm material into biofuels and environmentally friendly plastics.

After the harvest of the fruit from oil palm trees, large amounts of leftover biomass known as empty fruit bunch remain. The industry wants to use these leftover fruit bunches to produce bioethanol and biodegradable plastic, but has stumbled in their efforts to convert the leftovers in a cost-efficient way. The new fungal culture could make it possible to produce fermentable sugars from this huge amount of waste in a cost-effective way, thereby increasing its commercial value, said one of the lead researchers, Jin Chuan Wu, from the A*STAR Institute of Chemical and Engineering Sciences.

UW-Madison team develops novel hydrogen-producing photoelectrochemical cell using solar-driven biomass conversion as anode reaction

March 11, 2015

Researchers at the University of Wisconsin-Madison have developed an innovative hydrogen-producing photoelectrochemical cell (PEC), using solar-driven biomass conversion as the anode reaction. In a paper in the journal Nature Chemistry, the duo reports obtaining a near-quantitative yield and 100% Faradaic efficiency at ambient conditions without the use of precious-metal catalysts for this reaction, which is also thermodynamically and kinetically more favorable than conventional water oxidation at the anode. They thus demonstrated the utility of solar energy for biomass conversion (rather than catalysts) as well as the feasibility of using an oxidative biomass conversion reaction as an anode reaction in a hydrogen-forming PEC.

Chemistry Professor Kyoung-Shin Choi and postdoc Hyun Gil Cha said that their results suggest that solar-driven biomass conversion can be a viable anode reaction that has the potential to increase both the efficiency and the utility of PECs constructed for solar-fuel production.

New engineered metabolic pathways in yeast enable efficient fermentation of xylose from biomass

March 05, 2015

Researchers with the Energy Biosciences Institute (EBI), a partnership that includes Berkeley Lab and the University of California (UC) Berkeley, have introduced new metabolic pathways from the fungus Neurospora crassa into the yeast Saccharomyces cerevisiae to increase the fermentative production of fuels and other chemicals from biomass. An open access paper on the work is publised in the journal eLife.

While S. cerevisiae is the industry mainstay for fermenting sugar from cornstarch and sugarcane into ethanol, it requires substantial engineering to ferment sugars derived from plant cell walls such as cellobiose and xylose. The new metabolic pathways enable the yeast to ferment sugars from both cellulose (glucose) and hemicellulose (xylose)—the two major families of sugar found in the plant cell wall—efficiently, without the need of environmentally harsh pre-treatments or expensive enzyme cocktails.

Researchers at the University of California, Riverside led by Professor Charles Wyman, the Ford Motor Company Chair in Environmental Engineering, have developed a novel biomass pretreatment called co-solvent-enhanced lignocellulosic fractionation (CELF) to reduce enzyme costs significantly for high sugar yields from hemicellulose and cellulose—an essential development for the low-cost conversion of biomass to fuels.

As partners in the BioEnergy Science Center (BESC), the team from the Bourns College of Engineering Department of Chemical and Environmental Engineering and Center for Environmental Research and Technology (CE-CERT) have shown that CELF could eliminate about 90% of the enzymes needed for biological conversion of lignocellulosic biomass to fuels compared to prior practice. This development could mean reducing enzyme costs from about $1 per gallon of ethanol to about 10 cents or less, with an overall reduction in the cost of the production of cellulosic biofuels of 30% or more.

Engineered yeast produces ethanol from three important cellulosic biomass components simultaneously; higher yields, lower cost

February 11, 2015

A team led by researchers from the University of Illinois at Urbana−Champaign has, for the first time, integrated the fermentation pathways of both hexose and pentose sugars from biomass as well as an acetic acid reduction pathway into one strain of the yeast Saccharomyces cerevisiae using synthetic biology and metabolic engineering approaches.

The engineered strain co-utilized cellobiose, xylose, and acetic acid to produce ethanol with a substantially higher yield and productivity than the control strains. The results showed the unique synergistic effects of pathway coexpression, the team reported in a paper in the journal ACS Synthetic Biology.

IU researchers find Z. mobilis can use N2 gas in cellulosic ethanol production; potential major cost savings

February 03, 2015

Researchers at Indiana University have shown—for the first time to their knowledge—that the ethanol-producing bacterium, Zymomonas mobilis, can use nitrogen (N2) gas in lieu of traditional nitrogen supplements. The finding, reported in a paper in Proceedings of the National Academy of Sciences (PNAS), could make cellulosic ethanol more competitive with corn ethanol and gasoline.

The raw materials for cellulosic ethanol are low in nitrogen, a nutrient required for ethanol-producing microbes to grow, so cellulosic ethanol producers are estimated to spend millions of dollars annually on nitrogen fertilizers such as corn steep liquor and diammonium phosphate. The IU team led by biologist James B. McKinlay showed that Z. mobilis can use N2 as a nitrogen source, something that the more traditional ethanol-producer, baker’s yeast, cannot do.

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.

Researchers suggest hybrid graphene oxide/cellulose microfibers could supersede carbon fibers

Researchers from Nanjing Forestry University and the University of Maryland have designed high-performance microfibers by hybridizing two-dimensional (2D) graphene oxide (GO) nanosheets and one-dimensional (1D) nanofibrillated cellulose (NFC) fibers. The resulting well-aligned, strong microfibers have the potential to supersede carbon fibers due to their low cost, the team suggests in an open access paper published in the journal NPG Asia Materials.

The hybrid microfibers are much stronger than microfibers composed of 1D NFC or 2D GO alone. In their paper, they reported that experimental results and molecular dynamics simulations reveal the synergistic effect between GO and NFC: the bonding between neighboring GO nanosheets is enhanced by NFC because the introduction of NFC provides the extra bonding options available between the nanosheets.

NREL enzyme enables conversion of biomass to sugar up to 14x faster than current alternatives; changing the economics of conversion

January 13, 2015

Scientists at the US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) have developed an enzyme that can enable the conversion of biomass to sugars up to 14 times faster and more cheaply than competing catalysts in enzyme cocktails today. The enzyme called CelA, a cellulase from the bacterium Caldicellulosiruptor bescii, could thus could change the economics of biofuel conversion.

In one scenario, the best commercially used enzyme converted sugars at a 30% extent in seven days. CelA converted to double that extent. And while it took the alternative enzyme seven days to achieve that conversion, CelA, with a small boost from an extra beta glucosidase, achieved double in just about two days. Among CelA’s many attributes:

Advanced furoate esters biofuel company xF Technologies appoints Tom Stephens to board

xF Technologies Inc., developer of a family of low cost, renewable furoate esters (xF) for use as oxygenating blend components (5%-20%) in both gasoline and diesel fuels, as well as heating oil and other specialty applications, has appointed former GM Vice Chairman and Chief Technology Officer Tom Stephens as an independent director of the Company, effective immediately. (xF calls its family of molecules “408”—a phonetic play on furoate.)

xF’s continuous production technology uses common materials (steel and plastic) at moderate operating conditions to convert a biomass feedstock into a chemical intermediate that is subsequently combined with an alcohol to form the furoate ester product. The technology allows the production of numerous products depending on the type of or mixture of alcohols. These products exhibit fuel properties similar to each other and are named for the primary alcohol used in their production. For the four smallest chain alcohols, the resultant products are called Methyl 408, Ethyl 408, Isopropyl 408 and Butyl 408.

Vitruivan crowd-sourcing funding for novel biofuel from sewage treatment bio-solids

December 25, 2014

Vitruvian Energy is trying to crowd-fund its novel biofuel EEB (ethyl 3-ethoxybutyrate). EEB is produced from organic waste, including (and initially) sewage treatment bio-solids—the leftover, dirt-like organic material that remains after a community’s wastewater is treated. With 20 days left in the campaign, the company has raised $3,500 of a targeted $200,000.

EEB has higher energy content than ethanol: 26-29 MJ/L compared to 23. It can be used as a fuel additive to displace and clean up existing fossil fuels, and to lower their carbon footprint. Vitruvian has performed five years of research and development on EEB including combustion tests at Oak Ridge National Laboratory. Testing showed that blending EEB with diesel significantly reduces soot emissions, similar to how ethanol reduces emissions when blended with gasoline. EEB can also be blended with gasoline or burned to produce electricity.

Purdue process converts lignin in intact biomass to hydrocarbons for chemicals and fuels

December 18, 2014

A team of researchers from Purdue University’s Center for Direct Catalytic Conversion of Biomass to Biofuels, or C3Bio, has developed a process that uses a bimetallic Zn/Pd/C catalyst to convert lignin in intact lignocellulosic biomass directly into two methoxyphenol products (phenols are a class of aromatic hydrocarbon compounds used in perfumes and flavorings) leaving behind the carbohydrates as a solid residue.

Lignin-derived methoxyphenols can be further deoxygenated to propylcyclohexane—a cycloalkane. Cycloalkanes are important components of not only traditional vehicle fuels such as gasoline and diesel, but also jet fuels, such as Jet-A/Jet-A1/JP-8.

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.

Abengoa opens cellulosic ethanol plant in Hugoton; 1st commercial deployment of Abengoa enzymatic hydrolysis

October 17, 2014

The Hugoton cellulosic ethanol plant covers 400 acres, more than 380 of which will be used to store biomass from local farmers. Click to enlarge.

Abengoa held the grand opening of its cellulosic ethanol plant in Hugoton, Kansas, located about 90 miles (145 km) southwest of Dodge City. Abengoa’s new biorefinery finished construction in mid-August and began producing cellulosic ethanol at the end of September with the capacity to produce up to 25 million gallons (94.6 million liters) per year. Abengoa received a $132.4-million loan guarantee and a $97-million grant through the Department of Energy to support construction of the Hugoton facility.

The plant utilizes only “second generation” (2G) biomass feedstocks for ethanol production—i.e.non-edible agricultural crop residues (such as stalks and leaves) that do not compete with food or feed grain. The facility also features an electricity cogeneration component allowing it to operate as a self-sufficient renewable energy producer. By utilizing residual biomass solids from the ethanol conversion process, the plant generates 21 megawatts (MW) of electricity—enough to power itself and provide excess clean renewable power to the local Stevens County community.

A team from KU Leuven, Belgium, together with colleagues at the Leibniz Institute for Solid State and Materials Research in Germany, have designed a novel one-pot biphasic catalytic system that is able directly to transform cellulose into straight-chain alkanes (mainly n-hexane) with high yields.

The carbon-based yields are high (up to 82%) and the process completes in less than 6 hours at a comparatively mild 220 ˚C. The resulting bio-derived light naphtha fraction is a green feedstock suited for existing processes that produce aromatics, gasoline or olefins. With low-cost cellulosic residue and the absence of required pretreatment for this process, the researchers said, this approach seems highly promising en route to more sustainable chemicals and fuels. A paper on the work is published in the RSC journal Energy & Environmental Science.

BNL team devises new method to boost oil accumulation in plant leaves; implications for biofuel production

October 08, 2014

Researchers at DOE’s Brookhaven National Laboratory (BNL) have developed a new method to increase significantly the amount of oil accumulated in plant leaves, which could then serve as a source for biofuel production. Rather than adding genes, as some other research teams have done in their efforts to boost oil accumulation, the BNL method is based on is based on disabling or inactivating genes through simple mutations.

A series of detailed genetic studies revealed previously unknown biochemical details about plant metabolic pathways, including new ways to increase the accumulation of oil in leaves. Using these methods, the scientists grew experimental Arabidopsis plants (widely used as model organisms in plant biology), the leaves of which accumulated 9 wt % oil. This represented an approximately 150-fold increase in oil content compared to wild type leaves. A paper on their work is published in the journal The Plant Cell.

Researchers enhance yeast thermotolerance and ethanol tolerance; potential for significant impact on industrial biofuel production

October 03, 2014

The yeast Saccharomyces cerevisiae plays a central role in global biofuel production; currently, about 100 billion liters of ethanol are produced annually worldwide by fermentation of mainly sugarcane saccharose and corn starch by the yeast. There are also efforts underway to use the yeast with cellulosic biomass.

Boosting the yield and lowering the cost of fermentative production of biofuel would not only result in a significant immediate financial impact to commercial ethanol operations, but also support cost reductions that would be helpful to advance other advanced biofuels using the same or a similar pathway. However, boosting production has been gated by two key conditions: the ability of the yeast to tolerate higher temperatures, and the ability of the yeast to survive high concentrations of ethanol. Now, two new separate studies report progress on each of those fronts; the findings could have a significant impact on industrial biofuel production. Both papers are published in the current issue of the journal Science.

The US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) will award up to $60 million to two new programs ($30 million each). The Transportation Energy Resources from Renewable Agriculture (TERRA) program (DE-FOA-0001211) seeks to accelerate biomass yield gains (especially energy sorghum) through automated, predictive and systems-level approaches to biofuel crop breeding. The Advanced Research In Dry cooling (ARID) program (DE-FOA-0001197) aims to develop low-cost, highly efficient and scalable dry-cooling technologies for thermoelectric power plants.

TERRA. ARPA-E posited that there is an urgent need to accelerate energy crop development for the production of renewable transportation fuels from biomass.
