Science Journals Connector (OSTI)

This paper compares the use of sugar cane and corn for the production of ethanol with a focus on global warming and the current international debate about land use competition for food and biofuel production. The indicators used to compare the products are CO 2 emissions energy consumption sugar cane coproducts and deforestation. The life cycle emission inventory as a methodological tool is taken into account. The sustainability of socioeconomic development and the developing countries’ need to overcome barriers form the background against which the Brazilian government energy plans are analyzed.

But recalcitrance is not just a human trait - plants can be recalcitrant, too, and for them it is a matter of survival. Over millions of years, plants have evolved complex structural and chemical mechanisms to ward off assaults on their structural sugars by microbial and animal marauders. So it should be no surprise that when humans attempt to turn plant biomass into biofuels to meet our energy needs, we discover how stubborn and noncompliant our vegetative friends can be. Plant recalcitrance is one of

Transitions in biofuel technologies: An appraisal of the social impacts of cellulosic ethanol using the Delphi method  

Science Journals Connector (OSTI)

Abstract The sustainability of biofuels produced from food crops has become a focus of public and scientific scrutiny in the past few years. In the case of ethanol production, advanced technologies aim at avoiding controversy by using instead cellulosic biomass contained in wastes, residues and dedicated energy crops. However, despite the positive expectations that drive the development of the so-called “cellulosic” ethanol, sustainability challenges remain to be elucidated. Expecting to contribute to closing the gap in the field of the social assessment of biofuels, this paper reports and analyses the results of a Delphi survey that explored the perception of biofuel experts from different countries on potential social impacts of cellulosic ethanol. The complexity of appraising impacts emerges as one important conclusion of the study along with the realisation that these will be context-specific. Except for the case of municipal solid waste used as feedstock, such a technological transition might not be able to ameliorate the issues already faced by conventional ethanol, especially when production is based in poorer countries. This is because impacts of cellulosic ethanol depend upon both the technical dimension of its production and the socio-political context of locations where production might take place.

Chapter 8 - Integration of Ethanol Fermentation with Second Generation Biofuels Technologies  

Science Journals Connector (OSTI)

Abstract This chapter presents an overview of the challenges associated with integrating yeast fermentation into cellulosic biofuel processes, as well as the approaches that might overcome these challenges. The chapter first introduces the design considerations for first-generation ethanol fermentation processes using sugar cane and corn as feedstocks, with an emphasis on process constraints and operation strategies. The chapter then explores methods for improving yield, titer, productivity, and economics. These processing methods illustrate the challenges posed by the fermentation of ethanol from lignocellulose hydrolyzates, especially the differences in process constraints for high-productivity, high-product titer operations. Finally, the chapter discusses an example of aerobic seed cultivation of yeast using a hydrolyzate of dilute acid-hydrolyzed softwood hemicellulose.

Biofuels  

SciTech Connect

As David Rotman states in his article on biofuels, the conversion of biomass to liquid fuel is energy intensive--just like the conversion of coal or any other solid fuel to liquid fuel. That implies that the quantity of liquid fuel from biomass and the carbon dioxide released in the production process strongly depend upon the energy source used in the conversion process. Each year, the United States could produce about 1.3 billion tons of renewable biomass for use as fuel. Burning it would release about as much energy as burning 10 million barrels of diesel fuel per day. If converted to ethanol, the biomass would have the energy value of about five million barrels of diesel fuel per day. The remainder of the energy would be used by the biomass-to-liquids conversion plant. If a nuclear reactor or other energy source provides the energy for the biomass-to-liquids plants, the equivalent of over 12 million barrels of diesel fuel can be produced per day. If our goal is to end oil imports and avoid greenhouse-gas releases, we must combine biomass and nuclear energy to maximize biofuels production.

Enhancing biofuel production by ultrasonics  

Science Journals Connector (OSTI)

This work evaluated the use of high-powered ultrasonics to enhance biofuel production in terms of efficiency and costs. A wide range of feed stocks including switch grass corn stover and soft wood were studied. The effect of ultrasonic pretreatment on the removal of lignin for hydrolysis of starches and cellulose to fermentable sugars was studied. It was found that many of the pretreatments were very successful in enhancing lignin removal. For example time of dissolution of lingo-cellulosic biomass in ionic liquids was reduced from hours to minutes accompanied by a significant decrease in energy consumption compared to mechanical stirring. In addition it was found that hydrolysis of corn starch could be greatly accelerated utilizing ultrasonics. Economic models showed that the technology once implemented would have a payback period of less than one year. The work also focused on biodiesel production. It was seen that ultrasonics accelerated the transesterification process so that soy bean oil could be converted to biodiesel in less than a minute compared to 45 min using traditional methods. It was shown that yeast grown from glycerin a co-product of biodiesel production could be extracted and simultaneously converted to biodiesel with ultrasonics in less than a minute compared to traditional techniques that require multiple processes and relatively long cycle times (+1 h).

The effect of ultrasonic pretreatment on the removal of lignin to allow hydrolysis of cellulose to fermentable sugars was studied. Many pretreatment techniques proved to be successful in enhancing lignin removal. For example time of dissolution of ligno-cellulosic biomass in ionic liquids was reduced from hours to minutes accompanied by a significant decrease in energy consumption compared to mechanical stirring. In addition it was found that hydrolysis of corn starch could be greatly accelerated utilizing ultrasonics. Economic models showed that the technology once implemented would have a payback period of approximately 2.3 years. The work also explored biodiesel production using ultrasonics.

Biofuels  

Science Journals Connector (OSTI)

The principal types of biofuels that can be obtained from biorenewable energy sources are analyzed. As these sources, various sorts of biomass, which is accumulated upon photosynthetic conversion of solar energy, are considered. A typical feature of biofuel production is combination of chemical and biotechnological approaches.

Econometric estimation of the petroleum products consumption in Nigeria: Assessing the premise for biofuels adoption  

Science Journals Connector (OSTI)

Abstract The promotion and adoption of biofuels in Nigeria must be predicated on sufficient capacity for absorbing biofuels produced from the increasing investments in biofuels plantations, plants and processing facilities. This paper assesses the socioeconomic and related premises for biofuels development in Nigeria by conducting an econometric estimation of the petroleum products consumption. The paper first estimates aggregated petroleum product consumption, and then assess the response to specific petroleum products in terms of consumption, market (population), electricity generation, installed electricity generation capacity, and GDP. The result shows that all the petroleum products contribute significantly and about equally to aggregate petroleum consumption. The high proportion of petrol (about 44 percent) as a percentage of the aggregate petroleum product consumption validates the push for implementing the E10 petrol-ethanol blending for Nigeria. The consumption of diesel is also significant. Diesel is another petroleum product for which D20 biofuel blending policy has been proposed. The increase in population and GDP, coupled with the poor electricity situation, will keep driving the consumption of petroleum products. As the population increases, and the country continues to struggle to match electricity generation with population growth, the petrol-ethanol and diesel-biodiesel blending policy must be pursued tenaciously to ensure a reduction in carbon emission in Nigeria.

Multiphase Flow Modeling of Biofuel Production Processes  

SciTech Connect

As part of the Idaho National Laboratory's (INL's) Secure Energy Initiative, the INL is performing research in areas that are vital to ensuring clean, secure energy supplies for the future. The INL Hybrid Energy Systems Testing (HYTEST) Laboratory is being established to develop and test hybrid energy systems with the principal objective to safeguard U.S. Energy Security by reducing dependence on foreign petroleum. HYTEST involves producing liquid fuels in a Hybrid Energy System (HES) by integrating carbon-based (i.e., bio-mass, oil-shale, etc.) with non-carbon based energy sources (i.e., wind energy, hydro, geothermal, nuclear, etc.). Advances in process development, control and modeling are the unifying vision for HES. This paper describes new modeling tools and methodologies to simulate advanced energy processes. Needs are emerging that require advanced computational modeling of multiphase reacting systems in the energy arena, driven by the 2007 Energy Independence and Security Act, which requires production of 36 billion gal/yr of biofuels by 2022, with 21 billion gal of this as advanced biofuels. Advanced biofuels derived from microalgal biomass have the potential to help achieve the 21 billion gal mandate, as well as reduce greenhouse gas emissions. Production of biofuels from microalgae is receiving considerable interest due to their potentially high oil yields (around 600 gal/acre). Microalgae have a high lipid content (up to 50%) and grow 10 to 100 times faster than terrestrial plants. The use of environmentally friendly alternatives to solvents and reagents commonly employed in reaction and phase separation processes is being explored. This is accomplished through the use of hydrothermal technologies, which are chemical and physical transformations in high-temperature (200-600 C), high-pressure (5-40 MPa) liquid or supercritical water. Figure 1 shows a simplified diagram of the production of biofuels from algae. Hydrothermal processing has significant advantages over other biomass processing methods with respect to separations. These 'green' alternatives employ a hybrid medium that, when operated supercritically, offers the prospect of tunable physicochemical properties. Solubility can be rapidly altered and phases partitioned selectively to precipitate or dissolve certain components by altering temperature or pressure in the near-critical region. The ability to tune the solvation properties of water in the highly compressible near-critical region facilitates partitioning of products or by-products into separate phases to separate and purify products. Since most challenges related to lipid extraction are associated with the industrial scale-up of integrated extraction systems, the new modeling capability offers the prospect of addressing previously untenable scaling issues.

Ethanol Demand in United States Gasoline Production  

SciTech Connect

The Oak Ridge National Laboratory (OWL) Refinery Yield Model (RYM) has been used to estimate the demand for ethanol in U.S. gasoline production in year 2010. Study cases examine ethanol demand with variations in world oil price, cost of competing oxygenate, ethanol value, and gasoline specifications. For combined-regions outside California summer ethanol demand is dominated by conventional gasoline (CG) because the premised share of reformulated gasoline (RFG) production is relatively low and because CG offers greater flexibility for blending high vapor pressure components like ethanol. Vapor pressure advantages disappear for winter CG, but total ethanol used in winter RFG remains low because of the low RFG production share. In California, relatively less ethanol is used in CG because the RFG production share is very high. During the winter in California, there is a significant increase in use of ethanol in RFG, as ethanol displaces lower-vapor-pressure ethers. Estimated U.S. ethanol demand is a function of the refiner value of ethanol. For example, ethanol demand for reference conditions in year 2010 is 2 billion gallons per year (BGY) at a refiner value of $1.00 per gallon (1996 dollars), and 9 BGY at a refiner value of $0.60 per gallon. Ethanol demand could be increased with higher oil prices, or by changes in gasoline specifications for oxygen content, sulfur content, emissions of volatile organic compounds (VOCS), and octane numbers.

Sequencing of Multiple Clostridial Genomes Related to Biomass Conversion and Biofuel Production  

SciTech Connect

Modern methods to develop microbe-based biomass conversion processes require a system-level understanding of the microbes involved. Clostridium species have long been recognized as ideal candidates for processes involving biomass conversion and production of various biofuels and other industrial products. To expand the knowledge base for clostridial species relevant to current biofuel production efforts, we have sequenced the genomes of 20 species spanning multiple genera. The majority of species sequenced fall within the class III cellulosome-encoding Clostridium and the class V saccharolytic Thermoanaerobacteraceae. Species were chosen based on representation in the experimental literature as model organisms, ability to degrade cellulosic biomass either by free enzymes or by cellulosomes, ability to rapidly ferment hexose and pentose sugars to ethanol, and ability to ferment synthesis gas to ethanol. The sequenced strains significantly increase the number of noncommensal/nonpathogenic clostridial species and provide a key foundation for future studies of biomass conversion, cellulosome composition, and clostridial systems biology.

Integrating Glycerol to Methanol vs. Glycerol to Ethanol within the Production of Biodiesel from Algae  

Science Journals Connector (OSTI)

Abstract In this work, we use a superstrucutre optimization approach for the comparison between traditional biodiesel plants and the integration of glycerol to methanol production or its use to obtain ethanol within the production of biodiesel from algae. In the first case the glycerol is reformed, either autoreforming or steam reforming, the raw syngas purified and whose composition (H2:CO ratio) is adjusted for the production of methanol. The methanol once purified is used for the transesterification of the oil produced from the algae. In the second case we take advantage of the fact that the algae composition allows the simultaneous production of ethanol and biodiesel. The starch is liquified and saccharified to obtain glucose that is fermented to ethanol. On the other hand, the oil is transesterified with ethanol to produce biodiesel, either using an enzymatic or an homogeneous catalysts. The glycerol is fermented to ethanol. Both water-ethanol, streams from glucose and from glycerol are fed to a multieffect column and later to a molecular sieve. The dehydrated ethanol is used for the transesterification of the oil while the excess is sold as biofuel. Glycerol as byproduct is still interesting as long as its price is over $0.05 /kg. In terms of integrated facilities, the use of glycerol to produce ethanol requires almost twice the investment, but the production cost is a fourth lower with an increased production of biofuels by 50 %.

An Update on Ethanol Production and Utilization in Thailand—2014  

SciTech Connect

In spite of the recent political turmoil, Thailand has continued to develop its ethanol based alternative fuel supply and demand infrastructure. Its support of production and sales of ethanol contributed to more than doubling the production over the past five years alone. In April 2014, average consumption stood at 3.18 million liter per day- more than a third on its way to its domestic consumption goal of 9 million liters per day by 2021. Strong government incentives and the phasing out of non-blended gasoline contributed substantially. Concurrently, exports dropped significantly to their lowest level since 2011, increasing the pressure on Thai policy makers to best balance energy independency goals with other priorities, such as Thailand’s trade balance and environmental aspirations. Utilization of second generation biofuels might have the potential to further expand Thailand’s growing ethanol market. Thailand has also dramatically increased its higher ethanol blend vehicle fleet, with all new vehicles sold in the Thai market now being E20 capable and the number of E85 vehicles increasing three fold in the last year from 100,000 in 2013 to 300,000 in 2014.

Chapter 7 - Consolidated Bioprocessing for Ethanol Production  

Science Journals Connector (OSTI)

Abstract Ethanol production from cellulosic biomass involves five unit operations: pretreatment, cellulase production, enzymatic hydrolysis, microbial fermentation, and product recovery. ­Consolidated bioprocessing (CBP) combines the three biologically mediated steps (cellulase production, enzymatic hydrolysis, and microbial fermentation) into a single operation. CBP has outstanding potential for providing a breakthrough solution for the biological conversion of cellulosic biomass into ethanol. The implementation of CBP requires microbes that can produce a functional cellulase system while generating ethanol at high yields and concentrations. CBP-enabling microorganisms can be developed via two strategies: a native cellulolytic strategy, which involves identifying a naturally occurring cellulolytic microorganism (or a consortium of microorganisms) and then improving its ability to ferment sugars into ethanol at high yields and at high titers, and a recombinant cellulolytic strategy, which involves engineering noncellulolytic organisms so that they can utilize cellulose to produce ethanol at high yields and titers by heterologously expressing cellulases.

This report focuses on ethanol and biodiesel, the most widely available biofuels. From 2009 to the middle of 2012, the U.S. biofuels industry increased its output and prepared to meet an expanded Renewable Fuel Standard (RFS2),1 which requires increasing volumes of biofuels use. In 2011, the biofuels industry transitioned away from tax incentives for non-cellulosic biofuels, which expired at the end of 2011.

The Production of Ethanol and Hydrogen from Pineapple Peel by Saccharomyces Cerevisiae and Enterobacter Aerogenes  

Science Journals Connector (OSTI)

Abstract The production of biofuels including ethanol and hydrogen from agricultural waste is being concern as a renewable energy. Pineapple peel, a by-product of the pineapple processing industry, account for 29-40% (w/w) of total pineapple weight. 36.25±2.87% of cellulose was achieved from pineapple peel after pretreatment with water and heat at 100oC for 4 h. Afterwards, 0.5% (w/w) cellulase from Aspergillus niger (Sigma) was added for enzymatic hydrolysis. The maximum sugar production (34.03±1.30 g/L) was obtained after 24 h of incubation time. The enzyme hydrolysate was utilized as fermentation medium, with no nutritional addition to produce ethanol and hydrogen by Saccharomyces cerevisiae TISTR 5048 and Enterobacter aerogenes TISTR 1468. The maximum yield of ethanol (9.69 g/L) with no hydrogen production by S. cerevisiae was achieved after 72 h. However, the maximum ethanol and hydrogen from E. aerogenes were 1.38 g/L and 1,416 mL/L after 72 h and 12 h of cultivation, respectively.

Chapter 12 - Scale-Up and Commercialization of Algal Cultivation and Biofuel Production  

Science Journals Connector (OSTI)

Abstract Algae are currently being considered as a versatile feedstock for biofuel production because of their fast growth rate and high biomass productivity. Algae could simultaneously act as a carbon sink and water purifier if their cultivation were coupled with flue gas and wastewater treatment, respectively. Hence, an understanding of the overall supply chains for algal biofuel production is exceptionally important to determine whether it is worthwhile to scale up and commercialize algal cultivation for biofuel production. In this chapter, various aspects and constraints associated with the commercialization of algal biofuels are deliberated in detail, especially from the perspective of life-cycle energy balance. In addition, discussions on the economic assessments of algal biofuels are included in this chapter to provide an overview of the current state of algal biofuels in the fuel market. Potential algal biofuel conversion technologies, such as transesterification, starch hydrolysis and fermentation, pyrolysis, and hydrothermal liquefaction are also presented.

Physical Energy Accounting in California: A Case Study of Cellulosic Ethanol Production  

SciTech Connect

California's target for greenhouse gas reduction in part relies on the development of viable low-carbon fuel alternatives to gasoline. It is often assumed that cellulosic ethanol--ethanol made from the structural parts of a plant and not from the food parts--will be one of these alternatives. This study examines the physical viability of a switchgrass-based cellulosic ethanol industry in California from the point of view of the physical requirements of land, water, energy and other material use. Starting from a scenario in which existing irrigated pastureland and fiber-crop land is converted to switchgrass production, the analysis determines the total acreage and water supply available and the resulting total biofuel feedstock output under different assumed yields. The number and location of cellulosic ethanol biorefineries that can be supported is also determined, assuming that the distance from field to biorefinery would be minimized. The biorefinery energy input requirement, available energy from the fraction of biomass not converted to ethanol, and energy output is calculated at various levels of ethanol yields, making different assumptions about process efficiencies. The analysis shows that there is insufficient biomass (after cellulose separation and fermentation into ethanol) to provide all the process energy needed to run the biorefinery; hence, the purchase of external energy such as natural gas is required to produce ethanol from switchgrass. The higher the yield of ethanol, the more external energy is needed, so that the net gains due to improved process efficiency may not be positive. On 2.7 million acres of land planted in switchgrass in this scenario, the switchgrass outputproduces enough ethanol to substitute for only 1.2 to 4.0percent of California's gasoline consumption in 2007.

Ethanol Production for Automotive Fuel Usage  

SciTech Connect

The conceptual design of the 20 million gallon per year anhydrous ethanol facility a t Raft River has been completed. The corresponding geothermal gathering, extraction and reinjection systems to supply the process heating requirement were also completed. The ethanol facility operating on sugar beets, potatoes and wheat will share common fermentation and product recovery equipment. The geothermal fluid requirement will be approximately 6,000 gpm. It is anticipated that this flow will be supplied by 9 supply wells spaced at no closer than 1/4 mile in order to prevent mutual interferences. The geothermal fluid will be flashed in three stages to supply process steam at 250 F, 225 F and 205 F for various process needs. Steam condensate plus liquid remaining after the third flash will all be reinjected through 9 reinjection wells. The capital cost estimated for this ethanol plant employing all three feedstocks is $64 million. If only a single feedstock were used (for the same 20 mm gal/yr plant) the capital costs are estimated at $51.6 million, $43.1 million and $40. 5 million for sugar beets, potatoes and wheat respectively. The estimated capital cost for the geothermal system is $18 million.

Environmental indicators for sustainable production of algal biofuels  

Science Journals Connector (OSTI)

Abstract For analyzing sustainability of algal biofuels, we identify 16 environmental indicators that fall into six categories: soil quality, water quality and quantity, air quality, greenhouse gas emissions, biodiversity, and productivity. Indicators are selected to be practical, widely applicable, predictable in response, anticipatory of future changes, independent of scale, and responsive to management. Major differences between algae and terrestrial plant feedstocks, as well as their supply chains for biofuel, are highlighted, for they influence the choice of appropriate sustainability indicators. Algae strain selection characteristics do not generally affect which indicators are selected. The use of water instead of soil as the growth medium for algae determines the higher priority of water- over soil-related indicators. The proposed set of environmental indicators provides an initial checklist for measures of algal biofuel sustainability but may need to be modified for particular contexts depending on data availability, goals of stakeholders, and financial constraints. Use of these indicators entails defining sustainability goals and targets in relation to stakeholder values in a particular context and can lead to improved management practices.

PETRO: Higher Productivity Crops for Biofuels  

SciTech Connect

PETRO Project: The 10 projects that comprise ARPA-E’s PETRO Project, short for “Plants Engineered to Replace Oil,” aim to develop non-food crops that directly produce transportation fuel. These crops can help supply the transportation sector with agriculturally derived fuels that are cost-competitive with petroleum and do not affect U.S. food supply. PETRO aims to redirect the processes for energy and carbon dioxide (CO2) capture in plants toward fuel production. This would create dedicated energy crops that serve as a domestic alternative to petroleum-based fuels and deliver more energy per acre with less processing prior to the pump.

The potential expansion of biofuel production raises food, energy, and environmental challenges that require careful assessment of the impact of biofuel production on greenhouse gas (GHG) emissions, soil erosion, nutrient loading, and water quality. In this study, we describe a spatially explicit integrative modeling framework (SEIMF) to understand and quantify the environmental impacts of different biomass cropping systems. This SEIMF consists of three major components: (1) a geographic information system (GIS)-based data analysis system to define spatial modeling units with resolution of 56 m to address spatial variability, (2) the biophysical and biogeochemical model Environmental Policy Integrated Climate (EPIC) applied in a spatially-explicit way to predict biomass yield, GHG emissions, and other environmental impacts of different biofuel crops production systems, and (3) an evolutionary multiobjective optimization algorithm for exploring the trade-offs between biofuel energy production and unintended ecosystem-service responses. Simple examples illustrate the major functions of the SEIMF when applied to a nine-county Regional Intensive Modeling Area (RIMA) in SW Michigan to (1) simulate biofuel crop production, (2) compare impacts of management practices and local ecosystem settings, and (3) optimize the spatial configuration of different biofuel production systems by balancing energy production and other ecosystem-service variables. Potential applications of the SEIMF to support life cycle analysis and provide information on biodiversity evaluation and marginal-land identification are also discussed. The SEIMF developed in this study is expected to provide a useful tool for scientists and decision makers to understand sustainability issues associated with the production of biofuels at local, regional, and national scales.

Co-products from a biofuel production chain in crop disease management: A review  

Science Journals Connector (OSTI)

Abstract The economic importance of biofuel industrial production chains will increase in the coming years and will be a promising source of co-products that are useful for sustainable farming systems. However, the use of co-products that are obtained from the biofuel production chains, especially for crop disease management, is an under-explored area in the research community. The liquid and solid co-products that are related to the biofuel outputs of particular interest in crop protection are 1) oil-less seed meals and glycerin derived from the biodiesel chain, 2) steam-exploded liquid waste derived from a 2nd-generation bioethanol chain, and 3) charcoal (bio-char) obtained from the pyrolysis of plant biomass. It is interesting to include the suppressive composts that are obtained by composting agricultural waste and the exhausted biomasses originating from the different biofuel chains. This overview summarizes the nature, the effects, the mechanisms, the possible applications, and the use in crop protection of the most important solid and liquid co-products that are obtained from industrial processes, focusing on 2nd-generation biofuel outputs to control economically important plant diseases that are caused by soil-borne pathogens. The aim of this work is to review the available studies on the employment perspectives of biofuel chain co-products in crop protection by distinguishing the two concepts that are most important in sustainable farming systems: 1) the possible effects of these organic inputs in terms of interaction with beneficial soil microbial populations and 2) the possible relationships of these organic inputs in terms of interaction with the physiological and ecological processes of the crop–pathogen systems. This distinction will permit a good definition of the potential advantages of biofuel chain co-products with respect to the traditional organic amendments that are usually used in crop protection. It is evident from this review that biofuel chain co-products have great potential but sometimes give inconsistent disease control, which limits their use in crop protection. There is no doubt that the benefits of biofuel chain co-products outweigh their drawbacks, but the impact of this approach on pathogen populations and disease suppression is often unpredictable.

Carbon Calculator for Land Use Change from Biofuels Production (CCLUB). Users' manual and technical documentation.  

SciTech Connect

The Carbon Calculator for Land Use Change from Biofuels Production (CCLUB) calculates carbon emissions from land use change (LUC) for four different ethanol production pathways including corn grain ethanol and cellulosic ethanol from corn stover, miscanthus, and switchgrass. This document discusses the version of CCLUB released May 31, 2012 which includes corn, as did the previous CCLUB version, and three cellulosic feedstocks: corn stover, miscanthus, and switchgrass. CCLUB calculations are based upon two data sets: land change areas and above- and below-ground carbon content. Table 1 identifies where these data are stored and used within the CCLUB model, which is built in MS Excel. Land change area data is from Purdue University's Global Trade Analysis Project (GTAP) model, a computable general equilibrium (CGE) economic model. Section 2 describes the GTAP data CCLUB uses and how these data were modified to reflect shrubland transitions. Feedstock- and spatially-explicit below-ground carbon content data for the United States were generated with a surrogate model for CENTURY's soil organic carbon sub-model (Kwon and Hudson 2010) as described in Section 3. CENTURY is a soil organic matter model developed by Parton et al. (1987). The previous CCLUB version used more coarse domestic carbon emission factors. Above-ground non-soil carbon content data for forest ecosystems was sourced from the USDA/NCIAS Carbon Online Estimator (COLE) as explained in Section 4. We discuss emission factors used for calculation of international greenhouse gas (GHG) emissions in Section 5. Temporal issues associated with modeling LUC emissions are the topic of Section 6. Finally, in Section 7 we provide a step-by-step guide to using CCLUB and obtaining results.

Global poverty and biofuel production: food vs. fuel  

Science Journals Connector (OSTI)

From early 2008, the issue of rising global food prices moved to the forefront of the international political agenda. As a result of higher food prices, tens of millions of people were pushed into hunger and poverty around the world. Civil unrest flared up in North Africa, Vietnam and Haiti as countries introduced export restrictions on food subsidies and instituted price controls. Food price inflation has been sparking protests in North Africa that toppled longstanding presidents in Tunisia and Egypt. In the food markets, unfavourable weather conditions, rising fuel costs, rising biofuels production, and trade restrictions have added to upward price pressures. Higher food and fuel prices have serious macroeconomic effects throughout the global economy, including adverse effects on growth and inflation, and large swings in the terms of trade - with important balance of payments repercussions. In this paper, we analyse the immediate causes of food price inflation; in particular the role of biofuel, and discuss actions policy makers may need to take to ensure global food security.

Life cycle greenhouse gas impacts of ethanol, biomethane and limonene production from citrus waste  

Science Journals Connector (OSTI)

The production of biofuel from cellulosic residues can have both environmental and financial benefits. A particular benefit is that it can alleviate competition for land conventionally used for food and feed production. In this research, we investigate greenhouse gas (GHG) emissions associated with the production of ethanol, biomethane, limonene and digestate from citrus waste, a byproduct of the citrus processing industry. The study represents the first life cycle-based evaluations of citrus waste biorefineries. Two biorefinery configurations are studied—a large biorefinery that converts citrus waste into ethanol, biomethane, limonene and digestate, and a small biorefinery that converts citrus waste into biomethane, limonene and digestate. Ethanol is assumed to be used as E85, displacing gasoline as a light-duty vehicle fuel; biomethane displaces natural gas for electricity generation, limonene displaces acetone in solvents, and digestate from the anaerobic digestion process displaces synthetic fertilizer. System expansion and two allocation methods (energy, market value) are considered to determine emissions of co-products. Considerable GHG reductions would be achieved by producing and utilizing the citrus waste-based products in place of the petroleum-based or other non-renewable products. For the large biorefinery, ethanol used as E85 in light-duty vehicles results in a 134% reduction in GHG emissions compared to gasoline-fueled vehicles when applying a system expansion approach. For the small biorefinery, when electricity is generated from biomethane rather than natural gas, GHG emissions are reduced by 77% when applying system expansion. The life cycle GHG emissions vary substantially depending upon biomethane leakage rate, feedstock GHG emissions and the method to determine emissions assigned to co-products. Among the process design parameters, the biomethane leakage rate is critical, and the ethanol produced in the large biorefinery would not meet EISA's requirements for cellulosic biofuel if the leakage rate is higher than 9.7%. For the small biorefinery, there are no GHG emission benefits in the production of biomethane if the leakage rate is higher than 11.5%. Compared to system expansion, the use of energy and market value allocation methods generally results in higher estimates of GHG emissions for the primary biorefinery products (i.e., smaller reductions in emissions compared to reference systems).

Algae-based biofuel production as part of an industrial cluster  

Science Journals Connector (OSTI)

Abstract This paper presents a study on the production of biofuels from algae cultivated in municipal wastewater in Gothenburg, Sweden. A possible biorefinery concept is studied based on two cases; Case A) combined biodiesel and biogas production, and Case B) only biogas production. The cases are compared in terms of product outputs and impact on global CO2 emissions mitigation. The area efficiency of the algae-based biofuels is also compared with other biofuel production routes. The study investigates the collaboration between an algae cultivation, biofuel production processes, a wastewater treatment plant and an industrial cluster for the purpose of utilizing material flows and industrial excess heat between the actors. This collaboration provides the opportunity to reduce the CO2 emissions from the process compared to a stand-alone operation. The results show that Case A is advantageous to Case B with respect to all studied factors. It is found that the algae-based biofuel production routes investigated in this study has higher area efficiency than other biofuel production routes. The amount of algae-based biofuel possible to produce corresponds to 31 \\{MWfuel\\} for Case A and 26 \\{MWfuel\\} in Case B.

Biofuel, land and water: maize, switchgrass or Miscanthus?  

Science Journals Connector (OSTI)

The productive cellulosic crops switchgrass and Miscanthus are considered as viable biofuel sources. To meet the 2022 national biofuel target mandate, actions must be taken, e.g., maize cultivation must be intensified and expanded, and other biofuel crops (switchgrass and Miscanthus) must be cultivated. This raises questions on the use efficiencies of land and water; to date, the demand on these resources to meet the national biofuel target has rarely been analyzed. Here, we present a data-model assimilation analysis, assuming that maize, switchgrass and Miscanthus will be grown on currently available croplands in the US. Model simulations suggest that maize can produce 3.0–5.4 kiloliters (kl) of ethanol for every hectare of land, depending on the feedstock to ethanol conversion efficiency; Miscanthus has more than twice the biofuel production capacity relative to maize, and switchgrass is the least productive of the three potential sources of ethanol. To meet the biofuel target, about 26.5 million hectares of land and over 90 km3 of water (of evapotranspiration) are needed if maize grain alone is used. If Miscanthus was substituted for maize, the process would save half of the land and one third of the water. With more advanced biofuel conversion technology for Miscanthus, only nine million hectares of land and 45 km3 of water would probably meet the national target. Miscanthus could be a good alternative biofuel crop to maize due to its significantly lower demand for land and water on a per unit of ethanol basis.

Recombinant host cells and media for ethanol production  

DOE Patents (OSTI)

Disclosed are recombinant host cells suitable for degrading an oligosaccharide that have been optimized for growth and production of high yields of ethanol, and methods of making and using these cells. The invention further provides minimal media comprising urea-like compounds for economical production of ethanol by recombinant microorganisms. Recombinant host cells in accordance with the invention are modified by gene mutation to eliminate genes responsible for the production of unwanted products other than ethanol, thereby increasing the yield of ethanol produced from the oligosaccharides, relative to unmutated parent strains. The new and improved strains of recombinant bacteria are capable of superior ethanol productivity and yield when grown under conditions suitable for fermentation in minimal growth media containing inexpensive reagents. Systems optimized for ethanol production combine a selected optimized minimal medium with a recombinant host cell optimized for use in the selected medium. Preferred systems are suitable for efficient ethanol production by simultaneous saccharification and fermentation (SSF) using lignocellulose as an oligosaccharide source. The invention also provides novel isolated polynucleotide sequences, polypeptide sequences, vectors and antibodies.

Learning from the Brazilian biofuel experience  

Science Journals Connector (OSTI)

In the article `The ethanol program in Brazil' [1] José Goldemberg summarizes the key features of Brazil's sugarcane ethanol program—the most successful biofuel program in the world so far. In fact, as of 2005, Brazil was the world's largest producer of fuel ethanol. In addition to providing 40% of its gasoline market with ethanol, Brazil exports a significant amount of ethanol to Europe, Japan, and the United States. The success of the program is attributed to a variety of factors, including supportive governmental policies and favorable natural conditions (such as a tropical climate with abundant rainfall and high temperatures). As the article points out, in the early stages of the Brazilian ethanol program, the Brazilian government provided loans to sugarcane growers and ethanol producers (in most cases, they are the same people) to encourage sugarcane and ethanol production. Thereafter, ethanol prices were regulated to ensure that producers can economically sustain production and consumers can benefit from using ethanol. Over time, Brazil was able to achieve a price for ethanol that is lower than that for gasoline, on the basis of energy content. This lower cost is largely driving the widespread use of ethanol instead of gasoline by consumers in Brazil. In the United States, if owners of E85 flexible-fuel vehicles (FFVs) are expected to use E85 instead of gasoline in their FFVs, E85 will have to be priced competitively against gasoline on an energy-content basis. Compared with corn-based or sugar beet-based ethanol, Brazil's sugarcane-based ethanol yields considerably more favorable results in terms of energy balance and reductions in greenhouse gas emissions. These results are primarily due to (i) the dramatic increase of sugarcane yield in Brazil in the past 25 years and (ii) the use of bagasse instead of fossil fuels in ethanol plants to provide the heat needed for ethanol plant operations and to generate electricity for export to electric grids. Advancements in technology associated with both sugarcane farming and ethanol production have definitely played an important role in yielding the significant benefits associated with sugarcane ethanol. The United States produced about 4 billion gallons of ethanol from corn in 2005. Production was expected to increase to about 5 billion gallons by 2006. Corn-based ethanol achieves moderate reductions in greenhouse gas emissions. In the long run, the great potential of fuel ethanol lies in its production from cellulosic biomass, which is abundant in many regions of the world and can yield much greater reductions in greenhouse gas emissions and energy benefits. Figure 1 presents reductions in greenhouse emissions of several ethanol production pathways that were evaluated at the Argonne National Laboratory. Bagasse, a cellulosic biomass type already available in sugarcane ethanol plants, will certainly offer an opportunity for economically co-producing cellulosic ethanol and sugarcane ethanol in existing sugarcane ethanol plants. Figure 1. Greenhouse gas emissions per million Btu of gasoline and ethanol produced and used. Despite the encouraging progress of Brazil's ethanol program some issues will still need to be addressed. Figure 4 of [1] shows a significant drop in ethanol production in the 2000/2001 season. A steady supply of ethanol will be a key factor for the success of a fuel ethanol program. Consumers are not going to tolerate fluctuations in ethanol production. Instead, they will turn to conventional fuels for fueling their FFVs as a result of supply fluctuations, which can be detrimental to the success of the ethanol program. In addition to this, other environmental effects of biofuels in general, and sugarcane ethanol in particular, need to be assessed. Some have debated and speculated that Brazil's sugarcane ethanol program has caused (i) soil erosion and biodiversity problems by converting rainforests into sugarcane plantations and (ii) local air pollution problems as a result of burning in plantations before harvest. Also, as interest in biofuels heightens

Techno-Economic Analysis of Biochemical Scenarios for Production of Cellulosic Ethanol  

SciTech Connect

A techno-economic analysis on the production of cellulosic ethanol by fermentation was conducted to understand the viability of liquid biofuel production processes within the next 5-8 years. Initially, 35 technologies were reviewed, then a two-step down selection was performed to choose scenarios to be evaluated in a more detailed economic analysis. The lignocellulosic ethanol process was selected because it is well studied and portions of the process have been tested at pilot scales. Seven process variations were selected and examined in detail. Process designs were constrained to public data published in 2007 or earlier, without projecting for future process improvements. Economic analysis was performed for an 'nth plant' (mature technology) to obtain total investment and product value (PV). Sensitivity analysis was performed on PV to assess the impact of variations in process and economic parameters. Results show that the modeled dilute acid pretreatment process without any downstream process variation had the lowest PV of $3.40/gal of ethanol ($5.15/gallon of gasoline equivalent) in 2007 dollars. Sensitivity analysis shows that PV is most sensitive to feedstock and enzyme costs.

Ethanol Fuel Basics Ethanol Fuel Basics Ethanol Fuel Basics July 30, 2013 - 12:00pm Addthis biomass in beekers Ethanol is a renewable fuel made from various plant materials, which collectively are called "biomass." Ethanol contains the same chemical compound (C2H5OH) found in alcoholic beverages. Studies have estimated that ethanol and other biofuels could replace 30% or more of U.S. gasoline demand by 2030. Nearly half of U.S. gasoline contains ethanol in a low-level blend to oxygenate the fuel and reduce air pollution. Ethanol is also increasingly available in E85, an alternative fuel that can be used in flexible fuel vehicles. Several steps are required to make ethanol available as a vehicle fuel. Biomass feedstocks are grown and transported to ethanol production

Exploring Potential U.S. Switchgrass Production for Lignocellulosic Ethanol  

SciTech Connect

In response to concerns about oil dependency and the contributions of fossil fuel use to climatic change, the U.S. Department of Energy has begun a research initiative to make 20% of motor fuels biofuel based in 10 years, and make 30% of fuels bio-based by 2030. Fundamental to this objective is developing an understanding of feedstock dynamics of crops suitable for cellulosic ethanol production. This report focuses on switchgrass, reviewing the existing literature from field trials across the United States, and compiling it for the first time into a single database. Data available from the literature included cultivar and crop management information, and location of the field trial. For each location we determined latitude and longitude, and used this information to add temperature and precipitation records from the nearest weather station. Within this broad database we were able to identify the major sources of variation in biomass yield, and to characterize yield as a function of some of the more influential factors, e.g., stand age, ecotype, precipitation and temperature in the year of harvest, site latitude, and fertilization regime. We then used a modeling approach, based chiefly on climatic factors and ecotype, to predict potential yields for a given temperature and weather pattern (based on 95th percentile response curves), assuming the choice of optimal cultivars and harvest schedules. For upland ecotype varieties, potential yields were as high as 18 to 20 Mg/ha, given ideal growing conditions, whereas yields in lowland ecotype varieties could reach 23 to 27 Mg/ha. The predictive equations were used to produce maps of potential yield across the continental United States, based on precipitation and temperature in the long term climate record, using the Parameter-elevation Regressions on Independent Slopes Model (PRISM) in a Geographic Information System (GIS). Potential yields calculated via this characterization were subsequently compared to the Oak Ridge Energy Crop County Level data base (ORECCL), which was created at Oak Ridge National Laboratory (Graham et al. 1996) to predict biofuel crop yields at the county level within a limited geographic area. Mapped output using the model was relatively consistent with known switchgrass distribution. It correctly showed higher yields for lowland switchgrass when compared with upland varieties at most locations. Projections for the most northern parts of the range suggest comparable yields for the two ecotypes, but inadequate data for lowland ecotypes grown at high latitudes make it difficult to fully assess this projection. The final model is a predictor of optimal yields for a given climate scenario, but does not attempt to identify or account for other limiting or interacting factors. The statistical model is nevertheless an improvement over historical efforts, in that it is based on quantifiable climatic differences, and it can be used to extrapolate beyond the historic range of switchgrass. Additional refinement of the current statistical model, or the use of different empirical or process-based models, might improve the prediction of switchgrass yields with respect to climate and interactions with cultivar and management practices, assisting growers in choosing high-yielding cultivars within the context of local environmental growing conditions.

Analysis of advanced biofuels.  

SciTech Connect

Long chain alcohols possess major advantages over ethanol as bio-components for gasoline, including higher energy content, better engine compatibility, and less water solubility. Rapid developments in biofuel technology have made it possible to produce C{sub 4}-C{sub 5} alcohols efficiently. These higher alcohols could significantly expand the biofuel content and potentially replace ethanol in future gasoline mixtures. This study characterizes some fundamental properties of a C{sub 5} alcohol, isopentanol, as a fuel for homogeneous-charge compression-ignition (HCCI) engines. Wide ranges of engine speed, intake temperature, intake pressure, and equivalence ratio are investigated. The elementary autoignition reactions of isopentanol is investigated by analyzing product formation from laser-photolytic Cl-initiated isopentanol oxidation. Carbon-carbon bond-scission reactions in the low-temperature oxidation chemistry may provide an explanation for the intermediate-temperature heat release observed in the engine experiments. Overall, the results indicate that isopentanol has a good potential as a HCCI fuel, either in neat form or in blend with gasoline.

Importance of systems biology in engineering microbes for biofuel production  

SciTech Connect

Microorganisms have been rich sources for natural products, some of which have found use as fuels, commodity chemicals, specialty chemicals, polymers, and drugs, to name a few. The recent interest in production of transportation fuels from renewable resources has catalyzed numerous research endeavors that focus on developing microbial systems for production of such natural products. Eliminating bottlenecks in microbial metabolic pathways and alleviating the stresses due to production of these chemicals are crucial in the generation of robust and efficient production hosts. The use of systems-level studies makes it possible to comprehensively understand the impact of pathway engineering within the context of the entire host metabolism, to diagnose stresses due to product synthesis, and provides the rationale to cost-effectively engineer optimal industrial microorganisms.

Impact of agricultural-based biofuel production on greenhouse gas emissions from land-use change: Key modelling choices  

Science Journals Connector (OSTI)

Abstract Recent regulations on biofuels require reporting of greenhouse gas (GHG) emission reductions related to feedstock-specific biofuels. However, the inclusion of GHG emissions from land-use change (LUC) into law and policy remains a subject of active discussion, with LUC–GHG emissions an issue of intense research. This article identifies key modelling choices for assessing the impact of biofuel production on LUC–GHG emissions. The identification of these modelling choices derives from evaluation and critical comparison of models from commonly accepted biofuels–LUC–GHG modelling approaches. The selection and comparison of models were intended to cover factors related to production of agricultural-based biofuel, provision of land for feedstock, and GHG emissions from land-use conversion. However, some fundamental modelling issues are common to all stages of assessment and require resolution, including choice of scale and spatial coverage, approach to accounting for time, and level of aggregation. It is argued here that significant improvements have been made to address LUC–GHG emissions from biofuels. Several models have been created, adapted, coupled, and integrated, but room for improvement remains in representing LUC–GHG emissions from specific biofuel production pathways, as follows: more detailed and integrated modelling of biofuel supply chains; more complete modelling of policy frameworks, accounting for forest dynamics and other drivers of LUC; more heterogeneous modelling of spatial patterns of LUC and associated GHG emissions; and clearer procedures for accounting for the time-dependency of variables. It is concluded that coupling the results of different models is a convenient strategy for addressing effects with different time and space scales. In contrast, model integration requires unified scales and time approaches to provide generalised representations of the system. Guidelines for estimating and reporting LUC–GHG emissions are required to help modellers to define the most suitable approaches and policy makers to better understand the complex impacts of agricultural-based biofuel production.

Clean solid biofuel production from high moisture content waste biomass employing hydrothermal treatment  

Science Journals Connector (OSTI)

Abstract Our society currently faces three challenges, including resource depletion, waste accumulation and environmental degradation, leading to rapidly escalating raw material costs and increasingly expensive and restrictive waste disposal legislation. This work aims to produce clean solid biofuel from high moisture content waste biomass (bio-waste) with high nitrogen (N)/chlorine (Cl) content by mild hydrothermal (HT) conversion processes. The newest results are summarized and discussed in terms of the mechanical dewatering and upgrading, dechlorination, denitrification and coalification resulting from the HT pretreatment. Moreover, both the mono-combustion and co-combustion characteristics of the solid fuel are reviewed by concentrating on the pollutants emission control, especially the NO emission properties. In addition, the feasibility of this HT solid biofuel production process is also discussed in terms of “Energy Balance and economic viability”. As an alternative to dry combustion/dry pyrolysis/co-combustion, the HT process, combining the dehydration and decarboxylation of a biomass to raise its carbon content aiming to achieve a higher calorific value, opens up the field of potential feedstock for lignite-like solid biofuel production from a wide range of nontraditional renewable and plentiful wet agricultural residues, sludge and municipal wastes. It would contribute to a wider application of HT pretreatment bio-wastes for safe disposal and energy recycling.

Advancing Commercialization of Algal Biofuels Through Increased Biomass Productivity and Technology Integration  

SciTech Connect

Cellana is a leading developer of algae-based bioproducts, and its pre-commercial production of marine microalgae takes place at Cellana?s Kona Demonstration Facility (KDF) in Hawaii. KDF is housing more than 70 high-performing algal strains for different bioproducts, of which over 30 have been grown outside at scale. So far, Cellana has produced more than 10 metric tons of algal biomass for the development of biofuels, animal feed, and high-value nutraceuticals. Cellana?s ALDUO algal cultivation technology allows Cellana to grow non-extremophile algal strains at large scale with no contamination disruptions. Cellana?s research and production at KDF have addressed three major areas that are crucial for the commercialization of algal biofuels: yield improvement, cost reduction, and the overall economics. Commercially acceptable solutions have been developed and tested for major factors limiting areal productivity of algal biomass and lipids based on years of R&D work conducted at KDF. Improved biomass and lipid productivity were achieved through strain improvement, culture management strategies (e.g., alleviation of self-shading, de-oxygenation, and efficient CO2 delivery), and technical advancement in downstream harvesting technology. Cost reduction was achieved through optimized CO2 delivery system, flue gas utilization technology, and energy-efficient harvesting technology. Improved overall economics was achieved through a holistic approach by integration of high-value co-products in the process, in addition to yield improvements and cost reductions.

An Integrated Assessment of Location-Dependent Scaling for Microalgae Biofuel Production Facilities  

SciTech Connect

Successful development of a large-scale microalgae-based biofuels industry requires comprehensive analysis and understanding of the feedstock supply chain—from facility siting/design through processing/upgrading of the feedstock to a fuel product. The evolution from pilot-scale production facilities to energy-scale operations presents many multi-disciplinary challenges, including a sustainable supply of water and nutrients, operational and infrastructure logistics, and economic competitiveness with petroleum-based fuels. These challenges are addressed in part by applying the Integrated Assessment Framework (IAF)—an integrated multi-scale modeling, analysis, and data management suite—to address key issues in developing and operating an open-pond facility by analyzing how variability and uncertainty in space and time affect algal feedstock production rates, and determining the site-specific “optimum” facility scale to minimize capital and operational expenses. This approach explicitly and systematically assesses the interdependence of biofuel production potential, associated resource requirements, and production system design trade-offs. The IAF was applied to a set of sites previously identified as having the potential to cumulatively produce 5 billion-gallons/year in the southeastern U.S. and results indicate costs can be reduced by selecting the most effective processing technology pathway and scaling downstream processing capabilities to fit site-specific growing conditions, available resources, and algal strains.

Pathway engineering to improve ethanol production by thermophilic bacteria  

SciTech Connect

Continuation of a research project jointly funded by the NSF and DOE is proposed. The primary project goal is to develop and characterize strains of C. thermocellum and C. thermosaccharolyticum having ethanol selectivity similar to more convenient ethanol-producing organisms. An additional goal is to document the maximum concentration of ethanol that can be produced by thermophiles. These goals build on results from the previous project, including development of most of the genetic tools required for pathway engineering in the target organisms. As well, we demonstrated that the tolerance of C. thermosaccharolyticum to added ethanol is sufficiently high to allow practical utilization should similar tolerance to produced ethanol be demonstrated, and that inhibition by neutralizing agents may explain the limited concentrations of ethanol produced in studies to date. Task 1 involves optimization of electrotransformation, using either modified conditions or alternative plasmids to improve upon the low but reproducible transformation, frequencies we have obtained thus far.

Metabolic engineering of Klebsiella oxytoca M5A1 for ethanol production from xylose and glucose  

SciTech Connect

The efficient diversion of pyruvate from normal fermentative pathways to ethanol production in Klebsiella oxytoca M5A1 requires the expression of Zymomanas mobilis genes encoding both pyruvate decarboxylase and alcohol dehydrogenase. Final ethanol concentrations obtained with the best recombinant, strain M5A1 (pLOI555), were in excess of 40 g/liter with an efficiency of 0.48 g of ethanol (xylose) and 0.50 g of ethanol (glucose) per g of sugar, as compared with a theoretical maximum of 0.51 of ethanol per g of sugar. The maximal volumetric productivity per hour for both sugars was 2.0 g/liter. This volumetric productivity with xylose is almost twice that previously obtained with ethanologenic Escherichia coli. Succinate was also produced as a minor product during fermentation.

Techno-economic optimization of plant for raw ethanol production based on experimental data  

Science Journals Connector (OSTI)

Abstract This paper concerns techno-economic optimization of the production process of raw ethanol in a continuous distillation column as a part of the plant for production of rectified alcohol. Optimization was performed in order to determine the optimal ethanol concentration in the residue, which provides the minimum total production costs of existing plant. Total production costs are determined on the basis of experimental data, investment and operating costs and the estimated working life of the plant. It was found that ethanol concentration in the residue is significantly higher than values that can be found in the open literature.

Comparative genomics of xylose-fermenting fungi for enhanced biofuel production  

SciTech Connect

Cellulosic biomass is an abundant and underused substrate for biofuel production. The inability of many microbes to metabolize the pentose sugars abundant within hemicellulose creates specific challenges for microbial biofuel production from cellulosic material. Although engineered strains of Saccharomyces cerevisiae can use the pentose xylose, the fermentative capacity pales in comparison with glucose, limiting the economic feasibility of industrial fermentations. To better understand xylose utilization for subsequent microbial engineering, we sequenced the genomes of two xylose-fermenting, beetle-associated fungi, Spathaspora passalidarum and Candida tenuis. To identify genes involved in xylose metabolism, we applied a comparative genomic approach across 14 Ascomycete genomes, mapping phenotypes and genotypes onto the fungal phylogeny, and measured genomic expression across five Hemiascomycete species with different xylose-consumption phenotypes. This approach implicated many genes and processes involved in xylose assimilation. Several of these genes significantly improved xylose utilization when engineered into S. cerevisiae, demonstrating the power of comparative methods in rapidly identifying genes for biomass conversion while reflecting on fungal ecology.

The production of biofuel and bioelectricity associated with wastewater treatment by green algae  

Science Journals Connector (OSTI)

Abstract This study describes algal biofuel production, bioelectricity generation and wastewater treatment using Leptolyngbya sp. JPMTW1 (KF977831). The experiments were conducted in an AMFC (Algal Microbial Fuel Cell) photobioreactor (single-chamber). The pH, EC (electrical conductivity), COD (chemical oxygen demand) and TDS (total dissolved solids) decreased from 8.01 to 7.0, 982 to 854 (mS/cm), 255 to 112 (mg/L) and 490–427 (mg/L), respectively, over course of 7 days. Biomass production, rate of biomass production, chlorophyll a, b and “total chlorophyll” content increased with increasing time and were observed to be 3300 mg/L, 471.42 mg/L/day, 0.981 mg/L, 0.173 mg/L and 1.156 mg/L after 7 days. Lipid production and rate of lipid production were 1068.383 mg/g dry wt. biomass and 152.62 mg/g dry biomass/day. FTIR (Fourier transform infrared) spectra revealed the presence of protein, lipid, \\{FAs\\} (fatty acids), triglycerides and ester functional groups. FAME (fatty acid methyl esters) profile revealed the presence of C16:0, C18:2n-6, C18:1 and C16:1. The generation of electric potential by Leptolyngbya sp. JPMTW1 increased significantly (p ? 0.05) from 0.0211 to 0.264 mV within 7 days. The maximum power density (0.008 mW/cm2) was obtained at cell potential at 12 mV. This study shows that simultaneous production of biofuel, bioelectricity and wastewater treatment is possible by Leptolyngbya sp. JPMTW1.

A Second Generation Biofuel from Cellulosic Agricultural By-product Fermentation Using Clostridium Species for Electricity Generation  

Science Journals Connector (OSTI)

Abstract The production of second generation biofuel is essential for limiting food versus fuel competition. Butanol is one of the important biofuel for the future. Agricultural by-products namely bagasse and potato peel were hydrolyzed to produce readily fermented sugar for butanol fermentation. The butanol concentration was 1 – 2 g/l. To test the electricity generation, a customized generator was used for butanol combustion. The electricity produced was up to 1300 watts. Further improvements are needed in the hydrolysis method, medium composition, and generator design. This research has demonstrated that bagasse and potato peel are potential feedstock for producing butanol for generating electricity

Are biofuel concerns globally relevant? Prospects for a proposed pioneer bioethanol project in South Africa  

Science Journals Connector (OSTI)

Abstract Biofuels are controversial because of uncertain environmental benefits and reported social drawbacks, including ‘land grabs’ and threats to food security. The present study investigates the relevance of these concerns for a proposed bioethanol project in Cradock, South Africa. The proposed project is anticipated to lead to economic upliftment and could therefore contribute to reduce poverty and thus strengthen food security. With a projected annual production of up to 16,000 l ethanol per hectare, yields would be substantially higher than in most other countries. Agricultural activity would take place on existing farm land, or on biomes classified as ‘least concern’. We estimate a carbon footprint reduction of ~ 30% for sugar beet ethanol in the area. Because various global biofuel concerns do not apply to the proposed Cradock fuel ethanol project, we argue for a more nuanced approach for the evaluation of biofuel projects with more focus on case-specific attributes.

The rheological characterization of algae suspensions for the production of biofuels  

Science Journals Connector (OSTI)

This paper is concerned with the rheology of algae suspensions relevant to algae biofuel processing for a range of concentrations up to 15 vol. % using mostly a piezoaxial vibrator (PAV) rheometer as a method of measuring rheological properties. Linear viscoelastic (LVE) measurements of a Scenedesmus obliquus [culture collection of algae and protozoa (CCAP) 276/7] living algae strain were obtained and a curve for complex viscosity (?*) as a function of concentration/volume fraction derived. The PAV complex viscosity data increased exponentially with cell concentration and elasticity (G?) developed in a similar way with increasing concentration. The results indicated the presence of interaction between algae cells at all measured concentrations. For concentrations above ?5 vol. % steady shear data obtained using a Couette geometry showed non-Newtonian “shear-thinning” behavior and at higher concentrations there was a divergence from the Cox–Merz rule. A difference in the LVE rheological measurements was found for cells that were either alive or dead indicating that cell motility and significant interparticle contact and interactions influenced levels of viscoelasticity. The results are of potential scientific relevance and also useful in relation to the design of algae bioprocessing for the production of biofuels.

Evaluation of pretreatment methods for lignocellulosic ethanol production from energy cane variety L 79-1002  

Science Journals Connector (OSTI)

Abstract Approximately half of the 80 billion tons of crop produced annually around the world remains as residue that could serve as a renewable resource to produce valuable products such as ethanol and butanol. Ethanol produced from lignocellulosic biomass is a promising renewable alternative to diminishing oil and gas liquid fuels. Sugarcane is an important industry in Louisiana. The recently released variety of “energy cane” has great potential to sustain a competitive sugarcane industry. It has been demonstrated that fuel-grade ethanol can be produced from post harvest sugarcane residue in the past, but optimized ethanol production was not achieved. Optimization of the fermentation process requires efficient pretreatment to release cellulose and hemicellulose from lignocellulosic complex of plant fiber. Determining optimal pretreatment techniques for fermentation is essential for the success of lignocellulosic ethanol production process. The purpose of this study was to evaluate three pretreatment methods for the energy cane variety L 79-1002 for maximum lignocellulosic ethanol production. The pretreatments include alkaline pretreatment, dilute acid hydrolysis, and solid-state fungal pretreatment process using brown rot and white rot fungi. Pretreated biomass was enzymatically saccharified and subjected to fermentation using a recombinant Escherichia coli FBR5. The results revealed that all pretreatment processes produced ethanol. However, the best result was observed in dilute acid hydrolysis followed by alkaline pretreatment and solid-state fungal pretreatment.

Combining empirical and theory-based land-use modelling approaches to assess economic potential of biofuel production avoiding iLUC: Argentina as a case study  

Science Journals Connector (OSTI)

Abstract In this paper, a land-use modelling framework is presented combining empirical and theory-based modelling approaches to determine economic potential of biofuel production avoiding indirect land-use changes (iLUC) resulting from land competition with other functions. The empirical approach explores future developments in food and feed production to determine land availability and technical potential of biofuel production. The theory-based approach assesses the economic performance of biofuel crops on the surplus land in comparison with other production systems and determines the economic potential of biofuel production. The framework is demonstrated for a case study in Argentina to determine the development of biofuel potential from soy and switchgrass up to 2030. Two scenarios were considered regarding future developments of productivity in agriculture and livestock production. It was found that under a scenario reflecting a continuation of current trends, no surplus land is expected to become available. Nevertheless, the potential for soybean biodiesel is expected to keep increasing up to 103 PJ in 2030, due to the existence of a developed agro-industrial sector jointly producing feed and biodiesel. In case large technological developments occur, 32 Mha could become available in 2030, which would allow for a technical potential of 472 PJ soybean biodiesel and 1445 PJ switchgrass bioethanol. According to the economic assessment, an economic potential of 368 PJ of soy biodiesel and 1.1 EJ switchgrass bioethanol could be attained, at a feedstock production cost of 100–155 US$/ton and 20–45 US$/ton, respectively. The region of southwest Buenos Aires and La Pampa provinces appeared to be particularly promising for switchgrass. The ability of jointly assessing future developments in land availability, technical and economic potential of biofuel production avoiding iLUC and spatial distribution of viable locations for growing biofuel crops means that the proposed framework is a step forward in assessing the potential for biofuel production that is both economically viable and sustainably produced.

Speakers Secretary Steven Chu Duration 1:46 Topic Biofuels Bioenergy Credit Energy Department Video SECRETARY STEVEN CHU: This is a photograph of a perennial grass called miscanthus. It was grown without irrigation, without fertilizer. And in the autumn, you just shave it off. You use that to convert it to ethanol. The amount of ethanol in this particular plot of land outside the University of Illinois produces 15 times more ethanol than a similar plot of land if you grew corn, and the energy inputs are far less. So we need to develop methods in order to use these grassy, woody substances and also agricultural waste - wheat straw, rice straw, corn

Life cycle assessment (LCA) for biofuels in Brazilian conditions: A meta-analysis  

Science Journals Connector (OSTI)

Abstract The key objective of this study is to evaluate and compare the main environmental life cycle impacts and energy balance of ethanol from sugarcane and biodiesel from soybean and palm oil, in the Brazilian conditions. The methodological tool used was the Life Cycle Assessment (LCA), in Well-To-Tank (WTT) perspective. A process based on cradle-to-gate attribution LCA method, was applied as the technique to assess the health and environmental impacts of ethanol and biodiesel production systems. The environmental assessment was carried out using the SimaPro 7.0.1 software and the CML 2 baseline 2000 methodology, developed by the Institute of Environmental Sciences (CML). The assumed common analysis base in this paper was 1.0 MJ of energy released by combustion of the analyzed biofuels. The environmental impacts were quantified and ranked in categories of impacts: Abiotic Depletion Potential (ADP), Global Warming Potential (GWP), Human Toxicity Potential (HTP), Acidification Potential (ACP) and Eutrophication Potential (ETP). In addition, the results were compared by meta-analysis with previous published studies. The Net Energy Relation (NER) in the life cycle of biofuels is an important indicator of the technical and environmental performance evaluation of biofuels production. In this study the NER of ethanol and biodiesel from soybean and palm oil were estimated and compared with previous published studies. Direct and embodied energy inputs, based on defined system boundaries, were used to estimate the energy requirement of crops production, juice/oil extraction, and ethanol/biodiesel industrial production. It is possible to conclude, that biofuel production systems with higher agricultural yields and extensive use of co-products in its life cycle present best environmental results. The analysis of obtained results shows that the choices of co-products allocation method, transport distance and inventory database of the country, have significant influence on the results of the life cycle environmental performance of biofuels.

Designer organisms for photosynthetic production of ethanol from carbon dioxide and water  

DOE Patents (OSTI)

The present invention provides a revolutionary photosynthetic ethanol production technology based on designer transgenic plants, algae, or plant cells. The designer plants, designer algae, and designer plant cells are created such that the endogenous photosynthesis regulation mechanism is tamed, and the reducing power (NADPH) and energy (ATP) acquired from the photosynthetic water splitting and proton gradient-coupled electron transport process are used for immediate synthesis of ethanol (CH.sub.3CH.sub.2OH) directly from carbon dioxide (CO.sub.2) and water (H.sub.2O). The ethanol production methods of the present invention completely eliminate the problem of recalcitrant lignocellulosics by bypassing the bottleneck problem of the biomass technology. The photosynthetic ethanol-production technology of the present invention is expected to have a much higher solar-to-ethanol energy-conversion efficiency than the current technology and could also help protect the Earth's environment from the dangerous accumulation of CO.sub.2 in the atmosphere.

Ethanol and Methane Production from Oil Palm Frond by Two Stage SSF  

Science Journals Connector (OSTI)

Abstract A two step, included process producing ethanol from oil palm fronts (OPF) by two-stage simultaneous saccharification and Saccharomyces cerevisiae fermentation followed by anaerobic digestion of its effluent to produce methane was investigated. OPF was soaked in dilute sulfuric acid, hydrogen peroxide and water consequently pretreated by microwave for preparing of cellulose and followed by simultaneous saccharification and fermentation. The result indicated OPF soaking in water gave a maximal ethanol yield was 0.32 g-ethanol/g-glucose which was 62.75% of the ethanol theoretical yield (0.51g-ethanol/g-glucose). The effluent from the ethanol production process was used to produce methane with the yield of 514 ml CH4/g VS added. Therefore, soaking in water and microwave co-pretreatment could helpful due to its low toxicity and low corrosion compare to sulfuric acid and hydrogen peroxide which improves the efficiency of enzymatic hydrolysis. The maximum energy output of the process (745 kWh/ ton of OPF) was about 72% of the energy contributed by cellulose fraction, contained in the oil palm frond.

Conversion of wet ethanol to syngas via filtration combustion: An experimental and computational investigation  

Science Journals Connector (OSTI)

Ethanol is often promoted as the biofuel of the future, yet its acceptance as a fuel for combustion devices is limited by the cost of production. Since most combustion engines cannot tolerate high concentrations of water, the ethanol must be distilled and dehydrated, requiring large amounts of energy. Ethanol also has great potential as a feedstock for syngas consisting of hydrogen, carbon monoxide, and other species. The conversion, called reforming, of ethanol to syngas does not necessarily require dehydration or distillation, thus eliminating or reducing the costs associated with those processes. In addition, there is potential for obtaining additional hydrogen from the water in the mixture. In this paper, we investigate the conversion of wet ethanol, or ethanol that has not been fully distilled or dehydrated, to syngas in an inert porous reactor. Experimental and computational results over a range of equivalence ratios, inlet velocities, and water fractions are presented. The results indicate that wet ethanol is a promising biological source for hydrogen.

Trade-offs of Water Use for Hydropower Generation and Biofuel Production in the Zambezi Basin in Mozambique  

Science Journals Connector (OSTI)

Abstract In the Zambezi basin in Mozambique, hydropower production is an important economic resource, with substantial development envisaged for the next decades. Irrigated agriculture currently plays a minor role, but irrigation development has a large potential and is an important government policy goal, especially aiming at the cultivation of biofuel crops. This contribution assesses interrelations and trade-offs between these two water-dependent development options. Scenario simulations under different climate and development assumptions show that adverse impacts of irrigation withdrawal on hydropower are low. Consequently, the use of water for irrigated agriculture can generate higher economic benefits than the use for hydropower production.

Regional Algal Biofuel Production Potential in the Coterminous United States as Affected by Resource Availability Trade-offs  

SciTech Connect

The warm sunny climate and unoccupied arid lands in the American southwest are favorable factors for algae cultivation. However, additional resources affect the overall viability of specific sites and regions. We investigated the tradeoffs between growth rate, water, and CO2 availability and costs for two strains: N. salina and Chlorella sp. We conducted site selection exercises (~88,000 US sites) to produce 21 billion gallons yr-1 (BGY) of renewable diesel (RD). Experimental trials from the National Alliance for Advanced Biofuels and Bio-Products (NAABB) team informed the growth model of our Biomass Assessment Tool (BAT). We simulated RD production by both lipid extraction and hydrothermal liquefaction. Sites were prioritized by the net value of biofuel minus water and flue gas costs. Water cost models for N. salina were based on seawater and high salinity groundwater and for Chlorella, fresh and brackish groundwater. CO2 costs were based on a flue gas delivery model. Selections constrained by production and water were concentrated along the Gulf of Mexico and southeast Atlantic coasts due to high growth rates and low water costs. Adding flue gas constraints increased the spatial distribution, but the majority of sites remained in the southeast. The 21 BGY target required ~3.8 million hectares of mainly forest (41.3%) and pasture (35.7%). Exclusion in favor of barren and scrub lands forced most production to the southwestern US, but with increased water consumption (5.7 times) and decreased economic efficiency (-38%).

Comparison among Proposals for Energy Integration of Processes for 1G/2G Ethanol and Bioelectricity Production  

Science Journals Connector (OSTI)

Abstract Brazil has an important role in the world market of ethanol production and the implementation of technologies of second generation ethanol will intensify its production. In this work Pinch Analysis was used in order to perform energy integration of processes for first and second generation (1G/2G) ethanol and bioelectricity production, using hydrothermal and diluted acid pretreatments of sugarcane bagasse, both including and not including pentoses fermentation step. Processes that include pentoses fermentation step, for both considered pretreatments, have higher ethanol production when compared to the ones that do not make use of hemicellulose fraction of bagasse to produce ethanol, but steam consumption increases in the same order of magnitude of ethanol production. For the four evaluated scenarios the application of energy integration demonstrated a reduction in energy consumption of more than 50% when compared to the corresponding cases without any energy integration and of more than 30% when compared to partially integrated processes, as commonly found in Brazilian industrial plants. Besides the economical advantage, due to the decrease in costs of hot and cold utilities, energy integrated processes increase bagasse availability for production of second generation ethanol.

Turning Bacteria into Fuel: Cyanobacteria Designed for Solar-Powered Highly Efficient Production of Biofuels  

SciTech Connect

Broad Funding Opportunity Announcement Project: ASU is engineering a type of photosynthetic bacteria that efficiently produce fatty acids—a fuel precursor for biofuels. This type of bacteria, called Synechocystis, is already good at converting solar energy and carbon dioxide (CO2) into a type of fatty acid called lauric acid. ASU has modified the organism so it continuously converts sunlight and CO2 into fatty acids—overriding its natural tendency to use solar energy solely for cell growth and maximizing the solar-to-fuel conversion process. ASU’s approach is different because most biofuels research focuses on increasing cellular biomass and not on excreting fatty acids. The project has also identified a unique way to convert the harvested lauric acid into a fuel that can be easily blended with existing transportation fuels.

Hydrogen production from an ethanol reformer with energy saving approaches over various catalysts  

Science Journals Connector (OSTI)

The reforming of ethanol for hydrogen production was carried out in this study. The effects of ethanol supply rate, catalysts, O2/EtOH and different energy-saving approaches on the reforming temperature, H2 + CO (syngas) concentration and thermal efficiency were investigated. The results showed that the best H2 + CO concentration of 43.41% could be achieved by using rhodium (Rh), while the next best concentration of about 42.08% could be obtained using ruthenium (Ru). The results also showed that the conversion efficiency of ethanol, concentrations of H2 and CO, and the energy loss ratio could be improved by heat insulation and heat recycling; and the improvement in the reforming performance was greater by the Ru catalyst rather than by the Rh catalyst with the energy-saving approaches. The greatest improvement in hydrogen production was achieved when using the Ru catalyst with the addition of steam and heat recycling system under an O2/EtOH ratio of 0.625 and S/C ratio of 1.0.

Continuous syngas fermentation for the production of ethanol, n-propanol and n-butanol  

Science Journals Connector (OSTI)

Abstract Syngas fermentation to fuels is a technology on the verge of commercialization. Low cost of fermentation medium is important for process feasibility. The use of corn steep liquor (CSL) instead of yeast extract (YE) in Alkalibaculum bacchi strain CP15 bottle fermentations reduced the medium cost by 27% and produced 78% more ethanol. When continuous fermentation was performed in a 7-L fermentor, 6 g/L ethanol was obtained in the YE and YE-free media. When CSL medium was used in continuous fermentation, the maximum produced concentrations of ethanol, n-propanol and n-butanol were 8 g/L, 6 g/L and 1 g/L, respectively. n-Propanol and n-butanol were not typical products of strain CP15. A 16S rRNA gene-based survey revealed a mixed culture in the fermentor dominated by A. bacchi strain CP15 (56%) and Clostridium propionicum (34%). The mixed culture presents an opportunity for higher alcohols production from syngas.

Biofuel vs Bioinvasion: Seeding Policy Priorities

Biofuel vs Bioinvasion: Seeding Policy Priorities ... This rapid increase in cellulosic energy production has seeded a policy dilemma: while biofuels offer great promise and will be subsidized and supported by the federal government (EISA, 2008 Farm Bill), the development and promotion of potentially invasive plants as biofuels could place federal agencies in direct conflict with 1999 U.S. Executive Order (EO) 13112 (5, 6), and other laws and policy directives. ... Depending on their mission, federal agencies might engage in biofuel programs in a number of ways, such as (1) conducting biofuel research and development; (2) introducing and producing biofuel crops for experimentation and/or use; (3) subsidizing biofuel research, development, production, and marketing; (4) purchasing biofuels to supplement their energy demands; (5) establishing early detection and rapid response programs for escaped biofuel plants; (6) implementing long-term management of biofuel crops that become invasive; (7) restoring former biofuel production areas; and/or (8) regulating various aspects of production, use, and distribution of biofuels both domestically and internationally. ...

Assessing the environmental sustainability of biofuels  

Science Journals Connector (OSTI)

Biofuels vary in their potential to reduce greenhouse gas emissions when displacing fossil fuels. Savings depend primarily on the crop used for biofuel production, and on the effect that expanding its cultivation has on land use. Evidence-based policies should be used to ensure that maximal sustainability benefits result from the development of biofuels.

Commercial production of ethanol in the San Luis Valley, Colorado. Final report  

SciTech Connect

The commercial feasibility of producing between 76 and 189 million liters (20 to 50 million gallons) of ethanol annually in the San Luis Valley, Colorado using geothermal energy as the primary heat source was assessed. The San Luis Valley is located in south-central Colorado. The valley is a high basin situated approximately 2316 meters (7600 feet) above sea level which contains numerous warm water wells and springs. A known geothermal resource area (IGRA) is located in the east-central area of the valley. The main industry in the valley is agriculture, while the main industry in the surrounding mountains is lumber. Both of these industries can provide feedstocks for the production of ethanol.

Ethanol Production from Glucose and Xylose by Immobilized Zymomonas mobilis CP4(pZB5)  

SciTech Connect

Fermentation of glucose-xylose mixtures to ethanol was investigated in batch and continuous experiments using immobilized recombinant Zymomonas mobilis CP4(pZB5). This microorganism was immobilized by entrapment in k-carrageenan beads having a diameter of 1.5-2.5 mm. Batch experiments showed that the immobilized cells co-fermented glucose and xylose to ethanol and that the presence of glucose improved the xylose utilization rate. Batch fermentation of rice straw hydrolyzate containing 76 g/L glucose and 33.8 g/L xylose gave an ethanol concentration of 44.3 g/L after 24 hours, corresponding to a yeild of 0.46 g ethanol/g sugars. Comparable results were achieved with a synthetic sugar control. Continuous fermentation runs were performed in a laboratory scale fluidized-bed bioreactor (FBR). Glucose-xylose feed mixtures were run through the FBR at residence times of 2 to 4 hours. Glucose conversion to ethanol was maintained above 98% in all continuous runs. Xylose conversion to ethanol was highest at 91.5% for a feed containing 50 g/L glucose-13 g/L xylose at a dilution rate of 0.24 h-1. The xylose conversion to ethanol decreased with increasing feed xylose concentration, dilution rate and age of the immobilized cells. Volumetric ethanol productivities in the range of 6.5 to 15.3 g/L-h were obtained.

High Speed/ Low Effluent Process for Ethanol  

SciTech Connect

n this project, BPI demonstrated a new ethanol fermentation technology, termed the High Speed/ Low Effluent (HS/LE) process on both lab and large pilot scale as it would apply to wet mill and/or dry mill corn ethanol production. The HS/LE process allows very rapid fermentations, with 18 to 22% sugar syrups converted to 9 to 11% ethanol ‘beers’ in 6 to 12 hours using either a ‘consecutive batch’ or ‘continuous cascade’ implementation. This represents a 5 to 8X increase in fermentation speeds over conventional 72 hour batch fermentations which are the norm in the fuel ethanol industry today. The ‘consecutive batch’ technology was demonstrated on a large pilot scale (4,800 L) in a dry mill corn ethanol plant near Cedar Rapids, IA (Xethanol Biofuels). The pilot demonstrated that 12 hour fermentations can be accomplished on an industrial scale in a non-sterile industrial environment. Other objectives met in this project included development of a Low Energy (LE) Distillation process which reduces the energy requirements for distillation from about 14,000 BTU/gal steam ($0.126/gal with natural gas @ $9.00 MCF) to as low as 0.40 KW/gal electrical requirements ($0.022/gal with electricity @ $0.055/KWH). BPI also worked on the development of processes that would allow application of the HS/LE fermentation process to dry mill ethanol plants. A High-Value Corn ethanol plant concept was developed to produce 1) corn germ/oil, 2) corn bran, 3) ethanol, 4) zein protein, and 5) nutritional protein, giving multiple higher value products from the incoming corn stream.

The effect of CO2 regulations on the cost of corn ethanol production  

Science Journals Connector (OSTI)

To explore the effect of CO2 price on the effective cost of ethanol production we have developed a model that integrates financial and emissions accounting for dry-mill corn ethanol plants. Three policy options are modeled: (1) a charge per unit of life cycle CO2 emissions, (2) a charge per unit of direct biorefinery emissions only, and (3) a low carbon fuel standard (LCFS). A CO2 charge on life cycle emissions increases production costs by between $0.005 and $0.008 l?1 per $10 Mg?1 CO2 price increment, across all modeled plant energy systems, with increases under direct emissions somewhat lower in all cases. In contrast, a LCFS increases the cost of production for selected plant energy systems only: a LCFS requiring reductions in average fuel global warming intensity (GWI) with a target of 10% below the 2005 baseline increases the production costs for coal-fired plants only. For all other plant types, the LCFS operates as a subsidy. The findings depend strongly on the magnitude of a land use change adder. Some land use change adders currently discussed in the literature will push the GWI of all modeled production systems above the LCFS target, flipping the CO2 price from a subsidy to a tax.

A gas-phase reactor powered by solar energy and ethanol for H2 production  

Science Journals Connector (OSTI)

Abstract In the view of H2 as the future energy vector, we presented here the development of a homemade photo-reactor working in gas phase and easily interfacing with fuel cell devices, for H2 production by ethanol dehydrogenation. The process generates acetaldehyde as the main co-product, which is more economically advantageous with respect to the low valuable CO2 produced in the alternative pathway of ethanol photoreforming. The materials adopted as photocatalysts are based on TiO2 substrates but properly modified with noble (Au) and not-noble (Cu) metals to enhance light harvesting in the visible region. The samples were characterized by BET surface area analysis, Transmission Electron Microscopy (TEM) and UV–visible Diffusive Reflectance Spectroscopy, and finally tested in our homemade photo-reactor by simulated solar irradiation. We discussed about the benefits of operating in gas phase with respect to a conventional slurry photo-reactor (minimization of scattering phenomena, no metal leaching, easy product recovery, etc.). Results showed that high H2 productivity can be obtained in gas phase conditions, also irradiating titania photocatalysts doped with not-noble metals.

Nonrenewable energy cost of corn-ethanol in China  

Science Journals Connector (OSTI)

Nonrenewable energy cost is accounted for the believed renewable biofuel of corn-ethanol in China. By a process-based energy analysis, nonrenewable energy cost in the corn-ethanol production process incorporating agricultural crop production, industrial conversion and wastewater treatment is conservatively estimated as 1.70 times that of the ethanol energy produced, corresponding to a negative energy return in contrast to the positive ones previously reported. Nonrenewable energy cost associated with wastewater treatment usually ignored in previous researches is shown important in the energy balance. Denoting the heavy nonrenewability of the produced corn-ethanol, the calculated nonrenewable energy cost would rise to 3.64 folds when part of the nonrenewable energy cost associated with water consumption, transportation and environmental remediation is included. Due to the coal dominated nonrenewable energy structure in China, corn-ethanol processes in China are mostly a conversion of coal to ethanol. Validations and discussions are also presented to reveal policy implications against corn based ethanol as an alternative energy in long term energy security planning.

Ethanol production for automotive fuel usage. Final technical report, July 1979-August 1980  

SciTech Connect

Production of ethanol from potatoes, sugar beets, and wheat using geothermal resources in the Raft River area of Idaho was evaluated. The south-central region of Idaho produces approximately 18 million bushels of wheat, 1.3 million tons of sugar beets, and 27 million cwt potatoes annually. A 20-million-gallon-per-year ethanol facility has been selected as the largest scale plant that can be supported with the current agricultural resources. The conceptual plant was designed to operate on each of these three feedstocks for a portion of the year, but could operate year-round on any of them. The processing facility uses conventional alcohol technology and uses geothermal energy for all process heating. There are three feedstock preparation sections, although the liquefaction and saccharification steps for potatoes and wheat involve common equipment. The fermentation, distillation, and by-product handling sections are common to all three feedstocks. Maximum geothermal fluid requirements are approximately 6000 gpm. It is anticipated that this flow will be supplied by nine production wells located on private and BLM lands in the Raft River KGRA. The geothermal fluid will be flashed from 280/sup 0/F in three stages to supply process steam at 250/sup 0/F, 225/sup 0/F, and 205/sup 0/F for various process needs. Steam condensate plus liquid remaining after the third flash will be returned to receiving strata through six injection wells.

Comparison of energy potentials from combined ethanol and methane production using steam-pretreated corn stover impregnated with acetic acid  

Science Journals Connector (OSTI)

Abstract Acetic acid was investigated as a catalyst in steam pretreatment of corn stover. The purpose was to study ethanol production using either baker's yeast or a genetically modified pentose-fermenting version of Saccharomyces cerevisiae, KE6-12. Biogas production was investigated as an alternative for utilization of xylose. The high levels of acetic acid was found to be toxic using KE6-12. Some pentose fermentation was achieved, but the ethanol end concentration was almost the same as using baker's yeast (28 g L?1 compared to 27 g L?1). Using xylose for biogas production resulted in a high total energy recovery. The highest total energy recovery in the products, i.e. ethanol, methane and solids, obtained was 88% compared with the energy in ingoing raw material. This result was achieved when the solids and the liquid was separated after pretreatment.

Resetting global expectations from agricultural biofuels  

Science Journals Connector (OSTI)

Aggressive renewable energy policies have helped the biofuels industry grow at a rate few could have predicted. However, while discourse on the energy balance and environmental impacts of agricultural biofuel feedstocks are common, the potential they hold for additional production has received considerably less attention. Here we present a new biofuel yield analysis based on the best available global agricultural census data. These new data give us the first opportunity to consider geographically-specific patterns of biofuel feedstock production in different regions, across global, continental, national and sub-national scales. Compared to earlier biofuel yield tables, our global results show overestimates of biofuel yields by ~100% or more for many crops. To encourage the use of regionally-specific data for future biofuel studies, we calculated complete results for 20 feedstock crops for 238 countries, states, territories and protectorates.

Sources of Corn for Ethanol Production in the United States: A Review and Decomposition Analysis of the Empirical Data  

SciTech Connect

The use of corn for ethanol production in the United States quintupled between 2001 and 2009, generating concerns that this could lead to the conversion of forests and grasslands around the globe, known as indirect land-use change (iLUC). Estimates of iLUC and related food versus fuel concerns rest on the assumption that the corn used for ethanol production in the United States would come primarily from displacing corn exports and land previously used for other crops. A number of modeling efforts based on these assumptions have projected significant iLUC from the increases in the use of corn for ethanol production. The current study tests the veracity of these assumptions through a systematic decomposition analysis of the empirical data from 2001 to 2009. The logarithmic mean divisia index decomposition method (Type I) was used to estimate contributions of different factors to meeting the corn demand for ethanol production. Results show that about 79% of the change in corn used for ethanol production can be attributed to changes in the distribution of domestic corn consumption among different uses. Increases in the domestic consumption share of corn supply contributed only about 5%. The remaining contributions were 19% from added corn production, and 2% from stock changes. Yield change accounted for about two-thirds of the contributions from production changes. Thus, the results of this study provide little support for large land-use changes or diversion of corn exports because of ethanol production in the United States during the past decade.

Direct Conversion of Plant Biomass to Ethanol by Engineered Caldicellulosiruptor bescii  

SciTech Connect

Ethanol is the most widely used renewable transportation biofuel in the United States, with the production of 13.3 billion gallons in 2012 [John UM (2013) Contribution of the Ethanol Industry to the Economy of the United States]. Despite considerable effort to produce fuels from lignocellulosic biomass, chemical pretreatment and the addition of saccharolytic enzymes before microbial bioconversion remain economic barriers to industrial deployment [Lynd LR, et al. (2008) Nat Biotechnol 26(2):169-172]. We began with the thermophilic, anaerobic, cellulolytic bacterium Caldicellulosiruptor bescii, which efficiently uses unpretreated biomass, and engineered it to produce ethanol. Here we report the direct conversion of switchgrass, a nonfood, renewable feedstock, to ethanol without conventional pretreatment of the biomass. This process was accomplished by deletion of lactate dehydrogenase and heterologous expression of a Clostridium thermocellum bifunctional acetaldehyde/alcohol dehydrogenase. Whereas wild-type C. bescii lacks the ability to make ethanol, 70% of the fermentation products in the engineered strain were ethanol [12.8 mM ethanol directly from 2% (wt/vol) switchgrass, a real-world substrate] with decreased production of acetate by 38% compared with wild-type. Direct conversion of biomass to ethanol represents a new paradigm for consolidated bioprocessing, offering the potential for carbon neutral, cost-effective, sustainable fuel production.

Value Added Products from Hemicellulose Utilization in Dry Mill Ethanol Plants  

SciTech Connect

The Iowa Corn Promotion Board is the principal contracting entity for this grant funded by the US Department of Agriculture and managed by the US Department of Energy. The Iowa Corn Promotion Board subcontracted with New Jersey Institute of Technology, KiwiChem, Pacific Northwest National Lab and Idaho National Lab to conduct research for this project. KiwiChem conducted the economic engineering assessment of a dry-mill ethanol plant. New Jersey Institute of Technology conducted work on incorporating the organic acids into polymers. Pacific Northwest National Lab conducted work in hydrolysis of hemicellulose, fermentation and chemical catalysis of sugars to value-added chemicals. Idaho National Lab engineered an organism to ferment a specific organic acid. Dyadic, an enzme company, was a collaborator which provided in-kind support for the project. The Iowa Corn Promotion Board collaborated with the Ohio Corn Marketing Board and the Minnesota Corn Merchandising Council in providing cost share for the project. The purpose of this diverse collaboration was to integrate the hydrolysis, the conversion and the polymer applications into one project and increase the likelihood of success. This project had two primary goals: (1) to hydrolyze the hemicellulose fraction of the distillers grain (DG) coproduct coming from the dry-mill ethanol plants and (2) convert the sugars derived from the hemicellulose into value-added co-products via fermentation and chemical catalysis.

Utilization of agricultural wastes for production of ethanol. Progress report, October 1979-May 1980  

SciTech Connect

The project proposes to develop methods to utilize agricultural wastes, especially cottonseed hulls and peanut shells to produce ethanol. Initial steps will involve development of methods to break down cellulose to a usable form of substrates for chemical or biological digestion. The process of ethanol production will consist of (a) preparatory step to separate fibrous (cellulose) and non-fibrous (non-cellulosic compounds). The non-cellulosic residues which may include grains, fats or other substrates for alcoholic fermentation. The fibrous residues will be first pre-treated to digest cellulose with acid, alkali, and sulfur dioxide gas or other solvents. (b) The altered cellulose will be digested by suitable micro-organisms and cellulose enzymes before alcoholic fermentation. The digester and fermentative unit will be specially designed to develop a prototype for pilot plant for a continuous process. The first phase of the project will be devoted toward screening of a suitable method for cellulose modification, separation of fibrous and non-fibrous residues, the micro-organism and enzyme preparations. Work is in progress on: the effects of various microorganisms on the degree of saccharification; the effects of higher concentrations of acids, alkali, and EDTA on efficiency of microbial degradation; and the effects of chemicals on enzymatic digestion.

Development of gas turbine combustor fed with bio-fuel oil  

SciTech Connect

Considering the increasing interest in the utilization of biofuels derived from biomass pyrolysis, ENEL/CRT carried out some experimental investigations on feasibility of biofuels utilization in the electricity production systems. The paper considers the experimental activity for the development and the design optimization of a gas turbine combustor suitable to be fed with biofuel oil, on the basis of the pressurized combustion performance obtained in a small gas turbine combustor fed with bio-fuel oil and ethanol/bio-fuel oil mixtures. Combustion tests were performed using the combustion chamber of a 40 kWe gas turbine. A small pressurized rig has been constructed including a nozzle for pressurization and a heat recovering combustion air preheating system, together with a proper injection system consisting of two dual fuel atomizers. Compressed air allowed a good spray quality and a satisfactory flame instability, without the need of a pilot frame, also when firing crude bio-fuel only. A parametric investigation on the combustion performance has been performed in order to evaluate the effect of fuel properties, operating conditions and injection system geometry, especially as regards CO and NO{sub x} emissions and smoke index.

Energy and greenhouse gas emission effects of corn and cellulosic ethanol with technology improvements and land use changes.  

SciTech Connect

Use of ethanol as a transportation fuel in the United States has grown from 76 dam{sup 3} in 1980 to over 40.1 hm{sup 3} in 2009 - and virtually all of it has been produced from corn. It has been debated whether using corn ethanol results in any energy and greenhouse gas benefits. This issue has been especially critical in the past several years, when indirect effects, such as indirect land use changes, associated with U.S. corn ethanol production are considered in evaluation. In the past three years, modeling of direct and indirect land use changes related to the production of corn ethanol has advanced significantly. Meanwhile, technology improvements in key stages of the ethanol life cycle (such as corn farming and ethanol production) have been made. With updated simulation results of direct and indirect land use changes and observed technology improvements in the past several years, we conducted a life-cycle analysis of ethanol and show that at present and in the near future, using corn ethanol reduces greenhouse gas emission by more than 20%, relative to those of petroleum gasoline. On the other hand, second-generation ethanol could achieve much higher reductions in greenhouse gas emissions. In a broader sense, sound evaluation of U.S. biofuel policies should account for both unanticipated consequences and technology potentials. We maintain that the usefulness of such evaluations is to provide insight into how to prevent unanticipated consequences and how to promote efficient technologies with policy intervention.

Process Design and Economics for the Conversion of Algal Biomass to Biofuels: Algal Biomass Fractionation to Lipid- and Carbohydrate-Derived Fuel Products  

SciTech Connect

Beginning in 2013, NREL began transitioning from the singular focus on ethanol to a broad slate of products and conversion pathways, ultimately to establish similar benchmarking and targeting efforts. One of these pathways is the conversion of algal biomass to fuels via extraction of lipids (and potentially other components), termed the 'algal lipid upgrading' or ALU pathway. This report describes in detail one potential ALU approach based on a biochemical processing strategy to selectively recover and convert select algal biomass components to fuels, namely carbohydrates to ethanol and lipids to a renewable diesel blendstock (RDB) product. The overarching process design converts algal biomass delivered from upstream cultivation and dewatering (outside the present scope) to ethanol, RDB, and minor coproducts, using dilute-acid pretreatment, fermentation, lipid extraction, and hydrotreating.

Life cycle greenhouse gas (GHG) impacts of a novel process for converting food waste to ethanol and co-products  

Science Journals Connector (OSTI)

Abstract Waste-to-ethanol conversion is a promising technology to provide renewable transportation fuel while mitigating feedstock risks and land use conflicts. It also has the potential to reduce environmental impacts from waste management such as greenhouse gas (GHG) emissions that contribute to climate change. This paper analyzes the life cycle GHG emissions associated with a novel process for the conversion of food processing waste into ethanol (EtOH) and the co-products of compost and animal feed. Data are based on a pilot plant co-fermenting retail food waste with a sugary industrial wastewater, using a simultaneous saccharification and fermentation (SSF) process at room temperature with a grinding pretreatment. The process produced 295 L EtOH/dry t feedstock. Lifecycle GHG emissions associated with the ethanol production process were 1458 gCO2e/L EtOH. When the impact of avoided landfill emissions from diverting food waste to use as feedstock are considered, the process results in net negative GHG emissions and approximately 500% improvement relative to corn ethanol or gasoline production. This finding illustrates how feedstock and alternative waste disposal options have important implications in life cycle GHG results for waste-to-energy pathways.

Chapter 15 - Biomass to Liquid Biofuels Service Learning Projects and Case Studies  

Science Journals Connector (OSTI)

Abstract This chapter presents the liquid biofuel-related service learning projects undertaken by students in a northeastern region of United States over many years as part of the Bioenergy Program1. The students experiences are described. Particularly three different case studies are presented authored by the respective students who successfully completed their projects. The first case study, “cost analysis of oilseed production for biodiesel and the volatility in corn and crude” was conducted in in partnership with a local bioenergy farm to identify the tall barriers to break down in getting farmers to grow the oilseed crops analysis to see if dairy farmers could realize an economic benefit from dedicating 20% of their acreage to growing an oilseed for biofuel conversion. The second case study, “thermal heating fuel switch” quantified the economics of reducing the farm's thermal heating costs by using harvested biomass from the farm that has been using fuel oil and kerosene to heat its existing building infrastructure and hot water. The third case study, “Mobile Ethanol Distillery Unit: a feasibility study showed that although ethanol is a costly product to produce, if the feed value of feedstock such as sorghum distillers' grains is included it may become viable. Similar projects can be undertaken in any location in partnership with the local solid biofuel-based businesses, farms and communities.
