Algae Algae Nature Bulletin No. 556-A March 1, 1975 Forest Preserve District of Cook County George W. Dunne, President Roland F. Eisenbeis, Supt. of Conservation ALGAE These are the most exciting years that mankind has ever known -- the beginnings of the Space Age. Already, earthlings are making definite plans to visit the moon and Mars and even more distant parts of the universe. Because of the enormous amounts of fuel and equipment necessary for each pound of pay load to escape the earth's gravity and return, the supply of food and oxygen for travelers on these fantastically long journeys must be kept to a minimum. One of the suggested answers is to make use of the microscopic alga, Chlorella, which is found commonly in fresh water. In sunlight, like other green plants, it uses carbon dioxide and plant foods to grow and multiply. In the process it releases pure oxygen which could be used for breathing. Furthermore, a crop of excess Chlorella -- rich in food value -- could be harvested to feed the human passengers. They, in turn, produce the carbon dioxide and waste materials necessary to keep the alga growing. Such a miniature world can be imitated in a sealed glass container of water stocked with a bit of alga and a little aquatic animal life. Set near a window, they often survive for years.

Dark algae, life on Mars?  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Dark algae, life on Mars? Dark algae, life on Mars? Name: Jungle Fever Location: N/A Country: N/A Date: N/A Question: I'm probably writing this is vain since my numerous other notes weren't answered, but here goes. Does anyone out there know anything about the dark algae found in Siberia (or Antarctica, I don't remember which) or the primitive microbes found by Chris McKay that were revived by a drop of water? Also, can this concept be applied to the possibility of life on Mars? I'd also appreciate any information on extraterrestrial microorganisms or life forms. Much thanks. Replies: I don't know specifically about the algae that you mention. However, I do know that there are several kinds of algae that go into a sexual reproductive state in response to adverse conditions often including high temperatures or lack of moisture. This sexual phase results in formation of a fertilized zygote which becomes dormant until conditions are optimum for growth. This usually involves water - so a drop of water could initiate growth of the new alga, and it could reproduce asexually quite rapidly, until conditions trigger the sexual phase again. I see no reason why such a growth pattern couldn't apply to life on Mars or anywhere else. There isn't much information, as far as I'm aware, regarding extraterrestrial life. So far, none has been found, but it is likely, statistically, that there is some out there, somewhere. The SETI program (Search for extraterrestrial intelligence), funded in part by the Planetary Society, is trying to find higher forms of life by doing radio searches.

Formation of algae growth constitutive relations for improved algae modeling.  

SciTech Connect (OSTI)

This SAND report summarizes research conducted as a part of a two year Laboratory Directed Research and Development (LDRD) project to improve our abilities to model algal cultivation. Algae-based biofuels have generated much excitement due to their potentially large oil yield from relatively small land use and without interfering with the food or water supply. Algae mitigate atmospheric CO2 through metabolism. Efficient production of algal biofuels could reduce dependence on foreign oil by providing a domestic renewable energy source. Important factors controlling algal productivity include temperature, nutrient concentrations, salinity, pH, and the light-to-biomass conversion rate. Computational models allow for inexpensive predictions of algae growth kinetics in these non-ideal conditions for various bioreactor sizes and geometries without the need for multiple expensive measurement setups. However, these models need to be calibrated for each algal strain. In this work, we conduct a parametric study of key marine algae strains and apply the findings to a computational model.

Algae for Oxygen  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Algae for Oxygen Algae for Oxygen Name: Pam Burkardt Status: N/A Age: N/A Location: N/A Country: N/A Date: N/A Question: Hi, I am Pam Burkardt, a seventh grader at Fox Chapel School. I have a question on algae. I read somewhere that someday people might take bath tubs full of algae onto spaceships to provide oxygen for the crew. How much oxygen does algae give off, is this really possible? Replies: I think that most of the oxygen in the atmosphere comes in fact from one-celled plants in the oceans, like algae. They are likely to produce a lot of oxygen per unit weight because they don't have non-photosynthesizing bark, roots, branches, etc., nor (I think) a major dormant period like temperate-zone plants. The cost of space travel at present is dominated by the expense of heaving weight up into Earth orbit (it costs very little extra to send it to the Moon, for example, or Mars). For missions of short duration the weight of the compressed oxygen you need to carry is less than the weight of algae, water and extra plumbing you'd need to carry if you relied on algae to produce your oxygen. The important use of green plants would be in very long duration space flight (years) or permanent inhabitation of worlds like the Moon, where you need an unlimited supply of oxygen. Now if you want to fantasize, Venus' atmosphere is almost all carbon dioxide. Suppose you dropped a whole lot of specially gene-tailored one-celled plants into the atmosphere (not the surface, it's too hot). Why then they might eat up all the carbon dioxide and produce a breathable atmosphere. The "greenhouse effect" would go away, and Venus would become a nice habitable if tropical world only 50 million miles away.

SINGLE CELL PROTEIN | The Algae  

Science Journals Connector (OSTI)

Abstract Algae, as source of single-cell protein (SCP), is a term that refers to either microscopic single-cell true algae or prokaryotic cyanobacteria, and their growth is based on the use of carbon dioxide and light energy (autotrophic growth). In contrast with other SCP-producing organisms, algae are grown in many cases by processes resembling traditional agriculture, because they depend on large areas and sunlight radiation; on the other hand, modern production techniques include growth inside photobioreactors. Moreover, macroscopic algae are used widely as source of food, but they hardly can fit the SCP definition because of their multicellular nature and low protein content.

Abstract The feasibility of biodiesel production from microalgae as third generation biodiesel feedstock was studied in the present investigation. The studies were conducted to evaluate the growth patterns of the algae species i.e. Spirulina, Chlorella and pond water algae. The oil was extracted from the algae biomass and then transesterified. Simultaneous extraction and transesterification were also studied using different solvents. Maximum biodiesel yield was obtained using simultaneous extraction and transesterification using hexane as a solvent. The systematic characterization of algae biomass, algae oil and algae biodiesel was carried out to establish the potential of microalgae for biodiesel production.

Producing transportation fuels from algae: In search of synergy  

Science Journals Connector (OSTI)

Abstract The study found that promising algae biofuels R&D breakthroughs (hydrothermal liquefaction technology, high-frequency magnetic impulse cavitation reactors, etc.) and industry milestones (technologies of hydrorefining and catalytic selective oxidation among others), in order to move forward, require for implementation of new synergies and further innovations needed to improve economical production of advanced biofuels that are not applicable today. It seems that already viable state-of-the-art findings must be re-examined extensively in all of the different aspects in order to hasten the commercialisation of algal biofuels production in sustainable biorefineries. The same could be said about the feedstock selection for algal biomass production and its cultivation. It is the first step to successful large-scale algae cultivation in new regions of the world. Based on the above mentioned we identified fourteen promising algae species that can successfully grow in various regions of Russia under local climatic conditions. Samples collected during expedition were analysed at Lomonosov Moscow State University. Providing predetermined alternate periods of light and darkness and for temperature control of the different mediums to improve photosynthetic responses we investigated two different microalgal production systems: open ponds of the volume V=500 l and closed bioreactors of the volume V=1.0 l. Later on, a review on interdisciplinary synergies between biology and technology to open up new avenues of R&D in the field of algae-for-transport was carried out by leading universities of Lithuania, Russia, and Ukraine. In summary, we found that it is already possible to reduce the price of the 3rd and 4th generation biodiesel fuel from algae by applying the synergistic approaches to sustainable energy production highlighted in this paper, and probably some other ones as well.

Biodiversity of Harmful Marine Algae  

Science Journals Connector (OSTI)

Harmful algal blooms (HABs) are characterized by proliferation of algae, causing harmful effects to aquatic ecosystems or to human health. High taxonomic diversity and multiple phylogenetic origins complicate identification of common ecological and evolutionary strategies and thus predictions on global change consequences. Variation estimates revealed unexpectedly high genetic heterogeneity among HAB populations. Molecular fingerprinting of gene frequency and expression patterns can identify species invasions and global distributional shifts. Variation within populations must also be evaluated over seasonal and annual time scales. Such studies are essential to define and understand processes regulating HAB biodiversity and explain the linkages to ecosystem functionality.

Chapter 6 - Algae as a Fuel Source  

Science Journals Connector (OSTI)

Unlike higher plants, microalgae lack leaves or roots but are still capable of engaging in photosynthesis. Because of this, they produce about half of the earth’s atmospheric oxygen and simultaneously consume half of its carbon dioxide. This makes them desirable for the reduction of greenhouse gases while producing the means for the production of renewable fuels. Of the half million existing species, Chlorophyceae, the so-called green algae, are best for biodiesel production since they can exhibit a fourfold daily increase in number. Concerns about the sustainability of open ponds have led to closed photobioreactors for algae production. The high triglyceride content of algae makes them suitable for renewable diesel. The triglycerides are transesterified with methanol to form the corresponding methyl esters and byproduct glycerol. The products can be used as a drop-in jet fuel. Firms active in algae-based fuel development are Solazyme, Algenol Corp., and Origin Oil.

Electricity generation from sediment microbial fuel cells with algae-assisted cathodes  

Science Journals Connector (OSTI)

Abstract One major limiting factor for sediment microbial fuel cells (SMFC) is the low oxygen reduction rate in the cathode. The use of the photosynthetic process of the algae is an effective strategy to increase the oxygen availability to the cathode. In this study, \\{SMFCs\\} were constructed by introducing the algae (Chlorella vulgaris) to the cathode, in order to generate oxygen in situ. Cyclic voltammetry and dissolved oxygen analysis confirmed that C. vulgaris in the cathode can increase the dissolved oxygen concentration and the oxygen reduction rate. We showed that power generation of SMFC with algae-assisted cathode was 21 mW m?2 and was further increased to 38 mW m?2 with additional carbon nanotube coating in the cathode, which was 2.4 fold higher than that of the SMFC with bare cathode. This relatively simple method increases the oxygen reduction rate at a low cost and can be applied to improve the performance of SMFCs.

Algae control problems and practices workshop  

SciTech Connect (OSTI)

Western water resources are continuously facing increased demand from industry and the public. Consequently, many of these resources are required to perform multiple tasks as they cycle through the ecosystem. Many plants and animals depend upon these resources for growth. Algae are one group of plants associated with nutrient and energy cycles in many aquatic ecosystems. Although most freshwater algae are microscopic in size, they are capable of dominating and proliferating to the extent that the value of the water resource for both industrial and domestic needs is compromised. There is a great diversity of aquatic environments and systems in which algae may be found, and there are many varieties of treatment and control techniques available to reduce the impacts of excessive growth. This workshop was organized to exchange information about these control problems and practices.

Effects of ultrasound on unicellular algae  

Science Journals Connector (OSTI)

The effect of ultrasonic irradiation (up to 3W/cm2 and 1 MHz of frequency) on unicellular algae is experimentally studied. It is unambiguously shown that the damage of the cells and their breakage is to be related to cavitation. The dynamics of the breakage is examined from the point of view of practical application.

Algae are a diverse group of primarily aquatic organisms that are capable of using photosynthesis to generate biomass. This biomass can be used as feedstock for transportation fuels. In the near term, algae may also mitigate the effects of carbon dioxide from sources such as power plants - and in the future, they may be used to capture and reuse fossil-fuel-generated carbon dioxide directly from the atmosphere. This edition of Energy 101 shares the benefits of an algae-fueled future. For more information on algal biofuels from the Office of Energy Efficiency

Algae to Bio-Crude in Less Than 60 Minutes  

ScienceCinema (OSTI)

Engineers have created a chemical process that produces useful crude oil just minutes after engineers pour in harvested algae -- a verdant green paste with the consistency of pea soup. The PNNL team combined several chemical steps into one continuous process that starts with an algae slurry that contains as much as 80 to 90 percent water. Most current processes require the algae to be dried -- an expensive process that takes a lot of energy. The research has been licensed by Genifuel Corp.

Importance of algae oil as a source of biodiesel  

Science Journals Connector (OSTI)

Algae are the fastest-growing plants in the world. Industrial reactors for algal culture are open ponds, photobioreactors and closed systems. Algae are very important as a biomass source. Algae will some day be competitive as a source for biofuel. Different species of algae may be better suited for different types of fuel. Algae can be grown almost anywhere, even on sewage or salt water, and does not require fertile land or food crops, and processing requires less energy than the algae provides. Algae can be a replacement for oil based fuels, one that is more effective and has no disadvantages. Algae are among the fastest-growing plants in the world, and about 50% of their weight is oil. This lipid oil can be used to make biodiesel for cars, trucks, and airplanes. Microalgae have much faster growth-rates than terrestrial crops. the per unit area yield of oil from algae is estimated to be from 20,000 to 80,000 l per acre, per year; this is 7–31 times greater than the next best crop, palm oil. The lipid and fatty acid contents of microalgae vary in accordance with culture conditions. Most current research on oil extraction is focused on microalgae to produce biodiesel from algal oil. Algal-oil processes into biodiesel as easily as oil derived from land-based crops.

The economics of producing biodiesel from algae  

Science Journals Connector (OSTI)

Biodiesel is an alternative fuel for conventional diesel that is made from natural plant oils, animal fats, and waste cooking oils. This paper discusses the economics of producing biodiesel fuel from algae grown in open ponds. There is potential for large-scale production of biodiesel from algal farms on non-arable land; however, previous studies have failed to demonstrate an economically viable process that could be scalable to a commercialized industry. The problems include inconsistent and insufficient algal productivities, uncertain capital and operating costs, volatile market prices and unknown levels of government support. Although intensive work is being done on many technological issues, the economic studies and data are incomplete and out of date. This paper presents an updated financial analysis of the production and economic conditions that could have a profound effect on the success of this important alternative fuel production process.

Chapter 8 - Algae Oils as Fuels  

Science Journals Connector (OSTI)

Abstract Biologically produced fuels are considered potential and viable alternatives to meet the world’s fuel requirements. In this context, algal-based oil is of significant importance due to its renewable and carbon-neutral nature. Biosynthesis of triglycerides by utilizing CO2 (by biofixation) or wastewater under stress conditions via photoautotrophic, heterotrophic (photo/dark), or mixotrophic mechanisms enumerates the potential of microalgae for generation of renewable biodiesel. In addition to the algal cultivation, the conversion of the accumulated lipids to biodiesel is gaining considerable interest. Though there exist some constraints, the process of harnessing biofuel from microalgae is both economically viable and environmentally sustainable compared to the other oil-producing terrestrial crops. This chapter explores biofuel production using microalgae. Concerted efforts are made in this chapter to discuss the biochemistry pertaining to algal lipid synthesis, nutritional modes of algae, cultivation systems used for algal oil production, and the cascade of steps involved, from biomass cultivation to transesterification of the fuel. The ability of microalgae to capture CO2 and its survivability in wastewater is also elaborated in the context of lipid synthesis.

An updated comprehensive techno-economic analysis of algae biodiesel  

Science Journals Connector (OSTI)

Algae biodiesel is a promising but expensive alternative fuel to petro-diesel. To overcome cost barriers, detailed cost analyses are needed. A decade-old cost analysis by the U.S. National Renewable Energy Laboratory indicated that the costs of algae biodiesel were in the range of $0.53–0.85/L (2012 USD values). However, the cost of land and transesterification were just roughly estimated. In this study, an updated comprehensive techno-economic analysis was conducted with optimized processes and improved cost estimations. Latest process improvement, quotes from vendors, government databases, and other relevant data sources were used to calculate the updated algal biodiesel costs, and the final costs of biodiesel are in the range of $0.42–0.97/L. Additional improvements on cost-effective biodiesel production around the globe to cultivate algae was also recommended. Overall, the calculated costs seem promising, suggesting that a single step biodiesel production process is close to commercial reality.

Experimental and numerical investigations of mixing in raceway ponds for algae cultivation  

Science Journals Connector (OSTI)

Abstract The current high interest in the algae sector is leading to the development of several demo/commercial scale projects, either for the food market or bioenergy production. Raceway Ponds (RWPs) are a widely used technology for algae mass cultivation. \\{RWPs\\} were developed long time ago, and thus capital and operating costs are well assessed. Nevertheless, room still exists to further reduce operational costs. A possible route towards energy optimization and therefore operational cost reduction can be identified through a better understanding of the mixing phenomena. The focus of the present work is that vertical mixing, defined as the cyclical movement of the algal cells between surface and bottom layers of the culture, cannot be completely determined by considering only turbulence, and therefore it is not represented by the Re number. A 3D Computational Fluid Dynamic (CFD) analysis of a conventional RWP was carried out based on a multi-phase “Volume of Fluid” model, in order to investigate the flow field of the culture in the pond. The CFD results were compared with experimental measures on a 20 m2 pilot RWP. Once agreement among CFD and experimental results was shown, a statistical evaluation of the trajectories calculated for algae particles in the flow was carried out. The aim of this statistical evaluation was to define the level of vertical mixing in different sections of the pond. The model proposed was then used to scale-up the results to a demo/pre-commercial size RWP (500 m2). The standard deviation of the actual trajectory was calculated with respect to the undisturbed trajectory for each section modeled. The results of the simulation showed that a limited mixing is to be expected in RWPs. In the long straight parts of the pond vertical mixing is poor and algae tend to settle to the bottom. Only in the bends the vortexes produced by flow separation move part of the culture from the bottom to the top and vice-versa. This result does not fit with the practice, typically observed in large scale ponds, of reducing vortexes around the bends by placing baffles. The method described can be applied to different pond designs operated at different culture velocities.

Dewatering of microalgal cultures: A major bottleneck to algae-based fuels  

Science Journals Connector (OSTI)

Microalgae dewatering is a major obstruction to industrial-scale processing of microalgae for biofuel production. The dilute nature of harvested microalgal cultures creates a huge operational cost during dewatering thereby rendering algae-based fuels less economically attractive. Currently there is no superior method of dewatering microalgae. A technique that may result in a greater algal biomass may have drawbacks such as a high capital cost or high energy consumption. The choice of which harvesting technique to apply will depend on the species of microalgae and the final product desired. Algal properties such as a large cell size and the capability of the microalgae to autoflocculate can simplify the dewatering process. This article reviews and addresses the various technologies currently used for dewatering microalgal cultures along with a comparative study of the performances of the different technologies.

Green Algae as Model Organisms for Biological Fluid Dynamics  

E-Print Network [OSTI]

In the past decade the volvocine green algae, spanning from the unicellular $Chlamydomonas$ to multicellular $Volvox$, have emerged as model organisms for a number of problems in biological fluid dynamics. These include flagellar propulsion, nutrient uptake by swimming organisms, hydrodynamic interactions mediated by walls, collective dynamics and transport within suspensions of microswimmers, the mechanism of phototaxis, and the stochastic dynamics of flagellar synchronization. Green algae are well suited to the study of such problems because of their range of sizes (from 10 $\\mu$m to several millimetres), their geometric regularity, the ease with which they can be cultured and the availability of many mutants that allow for connections between molecular details and organism-level behavior. This review summarizes these recent developments and highlights promising future directions in the study of biological fluid dynamics, especially in the context of evolutionary biology, that can take advantage of these remarkable organisms.

Recent developments and prospects for algae-based fuels in the US  

Science Journals Connector (OSTI)

Abstract In recent years, algae-based fuels have received a growing interest of the industry sector and the US Government as a sustainable and renewable energy source. Algae constitute a unique feedstock as they contain high levels of both lipids and sugars and, thus, can be used for both biodiesel and ethanol production successively, in a two-stage process. In addition, the production of algae-based fuels shows a low environmental footprint and high energy efficiency. Algae can produce between 10 and 100 times more oil per acre as compared with traditional oil crops (e.g., oil palm) and can also grow 20–30 times faster than food crops. The production of algae does not compete with traditional crops for fresh water, high quality soil or fertilizers and, if cultivated off-shore, algae production does not require land resources at all. Furthermore, algae-based fuel is carbon-neutral, as algae assimilate similar amounts of CO2 for its growth as is released upon fuel combustion. From the policy perspective, algae-based fuels can provide a buffer for mitigating the food/feed vs. fuel problem in the long-term. The paper analyzes and discusses very recent developments in the algae R&D from the economic, environmental and policy perspective. It presents ways for solving the economic impediments as well as prospects for the commercialization of the algae technology in the near future. It covers multiple scientific and industry-related research and experimental studies to provide a comprehensive picture of the trends and patterns in the field.

The effect of algae species on biodiesel and biogas production observed by using a data model combines algae cultivation with an anaerobic digestion (ACAD) and a biodiesel process  

Science Journals Connector (OSTI)

Abstract The influence of an algae species based on the biodiesel yield was investigated by using a combined plant model from the literature. The model has six different processes: algal cultivation, the flocculation and separation process, biodiesel production, anaerobic digestion, scrubbing, and combined heat and power (CHP). The data model in the literature was operated with the values for Chlorella vulgaris. To investigate the roles of the algae species on the biodiesel yield in the model, two different algae species, Nannochloropsis sp. and Haematococcus pluvialis, were selected. Depending on the data from these algae in the literature, three different scenarios were modeled in the study. The model shows that all of the scenarios for biodiesel production can be totally independent of an external energy supply. Energy estimations for all of the applications scenarios show that the system produces more energy than the amount that is required for the processing operation.

The future viability of algae-derived biodiesel under economic and technical uncertainties  

Science Journals Connector (OSTI)

Abstract This study presents a techno-economic assessment of algae-derived biodiesel under economic and technical uncertainties associated with the development of algal biorefineries. A global sensitivity analysis was performed using a High Dimensional Model Representation (HDMR) method. It was found that, considering reasonable ranges over which each parameter can vary, the sensitivity of the biodiesel production cost to the key input parameters decreases in the following order: algae oil content > algae annual productivity per unit area > plant production capacity > carbon price increase rate. It was also found that the Return on Investment (ROI) is highly sensitive to the algae oil content, and to a lesser extent to the algae annual productivity, crude oil price and price increase rate, plant production capacity, and carbon price increase rate. For a large scale plant (100,000 tonnes of biodiesel per year) the production cost of biodiesel is likely to be £0.8–1.6 per kg.

Chapter 11 - Hydrothermal Upgradation of Algae into Value-added Hydrocarbons  

Science Journals Connector (OSTI)

Abstract Energy security, increasing oil prices, fossil resource depletion, and climate change are some of the greatest challenges faced by mankind at present. Third-generation biofuel feedstock and micro-and macroalgae have many advantages over the first and second generations of biofuels. In addition, defatted algae can also be used as a feedstock for production of hydrocarbons. Thermochemical methods are more efficient than any other routes for conversion of algae. Among thermochemical methods, hydrothermal upgradation is the most promising because it can process feedstock such as algae with very high moisture content. Various reactors, catalysts, and operating parameters have been tested to valorize algae by liquefaction and gasification, and promising results have been obtained. Breakthroughs in reactors and/or catalysts for hydrothermal upgradation, proper utilization of the side products obtained, and integration with various other methods to extract high-value hydrocarbons/products from algae would help make algal biorefinery economical and sustainable.

To geographers, the white cliffs mark the point at which England is closest to continental Europe. To scientists, the white cliffs are towering structures made of the chalky, white shells that envelop the single-celled photosynthetic alga known as Emiliania huxleyi. "Ehux" is a coccolithophore, with an exoskeleton made of calcium carbonate. Even though the process by which the alga's "armor" forms releases carbon dioxide, Ehux can trap as much as 20 percent of organic carbon, derived from CO2, in some marine ecosystems. The white cliffs of Dover are composed of the chalky, white shells that envelop the single-celled photosynthetic alga known as Emiliania huxleyi.

Pressurized thermal and hydrothermal decomposition of algae, wood chip residue, and grape marc: A comparative study  

Science Journals Connector (OSTI)

Abstract Pressurized thermal decomposition of two marine algae, Pinus radiata chip residue and grape marc using high temperature, high pressure reactions has been studied. The yields and composition of the products obtained from liquefactions under CO of a mixture of biomass and H2O (with or without catalyst) were compared with products from liquefaction of dry biomass under N2, at different temperatures, gas pressures and for CO runs, water to biomass ratios. Thermochemical reactions of algae produced significantly higher dichloromethane solubles and generally higher product yields to oil and asphaltene than Pinus radiata and grape marc under the reaction conditions used. Furthermore, the biofuels derived from algae contained significant concentrations of aliphatic hydrocarbons as opposed to those from radiata pine and grape marc which were richer in aromatic compounds. The possibility of air transport fuel production from algae thus appears to have considerable advantages over that from radiata pine and grape marc.

Re-utilization of Industrial CO2 for Algae Production Using a Phase Change Material  

SciTech Connect (OSTI)

This is the final report of a 36-month Phase II cooperative agreement. Under this project, Touchstone Research Laboratory (Touchstone) investigated the merits of incorporating a Phase Change Material (PCM) into an open-pond algae production system that can capture and re-use the CO2 from a coal-fired flue gas source located in Wooster, OH. The primary objective of the project was to design, construct, and operate a series of open algae ponds that accept a slipstream of flue gas from a coal-fired source and convert a significant portion of the CO2 to liquid biofuels, electricity, and specialty products, while demonstrating the merits of the PCM technology. Construction of the pilot facility and shakedown of the facility in Wooster, OH, was completed during the first two years, and the focus of the last year was on operations and the cultivation of algae. During this Phase II effort a large-scale algae concentration unit from OpenAlgae was installed and utilized to continuously harvest algae from indoor raceways. An Algae Lysing Unit and Oil Recovery Unit were also received and installed. Initial parameters for lysing nanochloropsis were tested. Conditions were established that showed the lysing operation was effective at killing the algae cells. Continuous harvesting activities yielded over 200 kg algae dry weight for Ponds 1, 2 and 4. Studies were conducted to determine the effect of anaerobic digestion effluent as a nutrient source and the resulting lipid productivity of the algae. Lipid content and total fatty acids were unaffected by culture system and nutrient source, indicating that open raceway ponds fed diluted anaerobic digestion effluent can obtain similar lipid productivities to open raceway ponds using commercial nutrients. Data were also collected with respect to the performance of the PCM material on the pilot-scale raceway ponds. Parameters such as evaporative water loss, temperature differences, and growth/productivity were tracked. The pond with the PCM material was consistently 2 to 5°C warmer than the control pond. This difference did not seem to increase significantly over time. During phase transitions for the PCM, the magnitude of the difference between the daily minimum and maximum temperatures decreased, resulting in smaller daily temperature fluctuations. A thin layer of PCM material reduced overall water loss by 74% and consistently provided algae densities that were 80% greater than the control pond.

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.

Algae biodiesel life cycle assessment using current commercial data  

Science Journals Connector (OSTI)

Abstract Autotrophic microalgae represent a potential feedstock for transportation fuels, but life cycle assessment (LCA) studies based on laboratory-scale or theoretical data have shown mixed results. We attempt to bridge the gap between laboratory-scale and larger scale biodiesel production by using cultivation and harvesting data from a commercial algae producer with ?1000 m2 production area (the base case), and compare that with a hypothetical scaled up facility of 101,000 m2 (the future case). Extraction and separation data are from Solution Recovery Services, Inc. Conversion and combustion data are from the Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation Model (GREET). The LCA boundaries are defined as “pond-to-wheels”. Environmental impacts are quantified as NER (energy in/energy out), global warming potential, photochemical oxidation potential, water depletion, particulate matter, and total \\{NOx\\} and SOx. The functional unit is 1 MJ of energy produced in a passenger car. Results for the base case and the future case show an NER of 33.4 and 1.37, respectively and GWP of 2.9 and 0.18 kg CO2-equivalent, respectively. In comparison, petroleum diesel and soy diesel show an NER of 0.18 and 0.80, respectively and GWP of 0.12 and 0.025, respectively. A critical feature in this work is the low algal productivity (3 g/m2/day) reported by the commercial producer, relative to the much higher productivities (20–30 g/m2/day) reported by other sources. Notable results include a sensitivity analysis showing that algae with an oil yield of 0.75 kg oil/kg dry biomass in the future case can bring the NER down to 0.64, more comparable with petroleum diesel and soy biodiesel. An important assumption in this work is that all processes are fully co-located and that no transport of intermediate or final products from processing stage to stage is required.

Niche of harmful alga Aureococcus anophagefferens revealed through ecogenomics  

SciTech Connect (OSTI)

Harmful algal blooms (HABs) cause significant economic and ecological damage worldwide. Despite considerable efforts, a comprehensive understanding of the factors that promote these blooms has been lacking because the biochemical pathways that facilitate their dominance relative to other phytoplankton within specific environments have not been identified. Here, biogeochemical measurements demonstrated that the harmful alga Aureococcus anophagefferens outcompeted co-occurring phytoplankton in estuaries with elevated levels of dissolved organic matter and turbidity and low levels of dissolved inorganic nitrogen. We subsequently sequenced the first HAB genome (A. anophagefferens) and compared its gene complement to those of six competing phytoplankton species identified via metaproteomics. Using an ecogenomic approach, we specifically focused on the gene sets that may facilitate dominance within the environmental conditions present during blooms. A. anophagefferens possesses a larger genome (56 mbp) and more genes involved in light harvesting, organic carbon and nitrogen utilization, and encoding selenium- and metal-requiring enzymes than competing phytoplankton. Genes for the synthesis of microbial deterrents likely permit the proliferation of this species with reduced mortality losses during blooms. Collectively, these findings suggest that anthropogenic activities resulting in elevated levels of turbidity, organic matter, and metals have opened a niche within coastal ecosystems that ideally suits the unique genetic capacity of A. anophagefferens and thus has facilitated the proliferation of this and potentially other HABs.

The potential of algae blooms to produce renewable gaseous fuel  

Science Journals Connector (OSTI)

Abstract Ulva lactuca (commonly known as sea letuce) is a green sea weed which dominates Green Tides or algae blooms. Green Tides are caused by excess nitrogen from agriculture and sewage outfalls resulting in eutrophication in shallow estuaries. Samples of U. lactuca were taken from the Argideen estuary in West Cork on two consecutive years. In year 1 a combination of three different processes/pretreatments were carried out on the Ulva. These include washing, wilting and drying. Biomethane potential (BMP) assays were carried out on the samples. Fresh Ulva has a biomethane yield of 183 L CH4/kg VS. For dried, washed and macerated Ulva a BMP of 250 L CH4/kg VS was achieved. The resource from the estuary in West Cork was shown to be sufficient to provide fuel to 264 cars on a year round basis. Mono-digestion of Ulva may be problematic; the C:N ratio is low and the sulphur content is high. In year 2 co-digestion trials with dairy slurry were carried out. These indicate a potential increase in biomethane output by 17% as compared to mono-digestion of Ulva and slurry.

Bioelectricity generation and microcystins removal in a blue-green algae powered microbial fuel cell  

Science Journals Connector (OSTI)

Bioelectricity production from blue-green algae was examined in a single chamber tubular microbial fuel cell (MFC). The blue-green algae powered MFC produced a maximum power density of 114 mW/m2 at a current density of 0.55 mA/m2. Coupled with the bioenergy generation, high removal efficiencies of chemical oxygen demand (COD) and nitrogen were also achieved in MFCs. Over 78.9% of total chemical oxygen demand (TCOD), 80.0% of soluble chemical oxygen demand (SCOD), 91.0% of total nitrogen (total-N) and 96.8% ammonium–nitrogen (NH3–N) were removed under closed circuit conditions in 12 days, which were much more effective than those under open circuit and anaerobic reactor conditions. Most importantly, the MFC showed great ability to remove microcystins released from blue-green algae. Over 90.7% of MC-RR and 91.1% of MC-LR were removed under closed circuit conditions (500 ?). This study showed that the MFC could provide a potential means for electricity production from blue-green algae coupling algae toxins removal.

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.

Biodiesel production from algae by using heterogeneous catalysts: A critical review  

Science Journals Connector (OSTI)

Abstract The numerous challenges associated with declining fossil fuel reserves as energy sources, have accounted for a shift to biofuels as alternatives. However, transesterification of animal fats and edible vegetable oils using homogeneous acids and bases for biodiesel production is recently considered unsustainable by industries, particularly due to food versus fuel competition, and economic and environmental challenges associated with the feedstocks and catalyst systems, respectively. The paper therefore presents a critical review on the prospects of non-edible oil (i.e. algae oil) for biodiesel production via heterogeneous catalysis. It covers the advantages of algae oil exploitation over edible oil feedstocks, progress made in the oil extraction, available heterogeneous catalyst systems and reaction mechanisms, optimum transesterification conditions and the way forward. As the economic feasibility of biodiesel production from algae is supported by the valorization of glycerol as by-product, we have also highlighted key available heterogeneous catalysts to upgrade glycerol into more useful industrial products.

The carbon footprint and non-renewable energy demand of algae-derived biodiesel  

Science Journals Connector (OSTI)

Abstract We determine the environmental impact of different biodiesel production strategies from algae feedstock in terms of greenhouse gas (GHG) emissions and non-renewable energy consumption, we then benchmark the results against those of conventional and synthetic diesel obtained from fossil resources. The algae cultivation in open pond raceways and the transesterification process for the conversion of algae oil into biodiesel constitute the common elements among all considered scenarios. Anaerobic digestion and hydrothermal gasification are considered for the conversion of the residues from the wet oil extraction route; while integrated gasification–heat and power generation and gasification–Fischer–Tropsch processes are considered for the conversion of the residues from the dry oil extraction route. The GHG emissions per unit energy of the biodiesel are calculated as follows: 41 g e-CO2/MJb for hydrothermal gasification, 86 g e-CO2/MJb for anaerobic digestion, 109 g e-CO2/MJb for gasification–power generation, and 124 g e-CO2/MJb for gasification–Fischer–Tropsch. As expected, non-renewable energy consumptions are closely correlated to the GHG values. Also, using the High Dimensional Model Representation (HDMR) method, a global sensitivity analysis over the entire space of input parameters is performed to rank them with respect to their influence on key sustainability metrics. Considering reasonable ranges over which each parameter can vary, the most influential input parameters for the wet extraction route include extractor energy demand and methane yield generated from anaerobic digestion or hydrothermal gasification of the oil extracted-algae. The dominant process input parameters for the dry extraction route include algae oil content, dryer energy demand, and algae annual productivity. The results imply that algal biodiesel production from a dried feedstock may only prove sustainable if a low carbon solution such as solar drying is implemented to help reducing the water content of the feedstock.

Comparison of electrogenic capabilities of microbial fuel cell with different light power on algae grown cathode  

Science Journals Connector (OSTI)

Electricity generation capabilities of microbial fuel cell with different light power on algae grown cathode were compared. Results showed that microbial fuel cell with 6 and 12 W power of light always produced higher voltage and power density than with 18 and 26 W. Similarly, microbial fuel cell with 6 and 12 W of light power always displayed higher Coulombic efficiency and specific power than the one with 18 and 26 W. The results also showed that microbial fuel cell with covered anodic chamber always displayed higher voltage, power density, Coulombic efficiency and specific power than the one without covered anodic chamber. Binary quadratic equations can be used to express the relationships between the light power and the voltage, power density, Coulombic efficiency and specific power. Although lower power of light on algae grown cathode and covering anodic chamber will increase system’s electricity production, they will not significantly reduce its internal resistance.

Influence of Fatty Acid Structure on Fuel Properties of Algae Derived Biodiesel  

Science Journals Connector (OSTI)

Abstract Physical and chemical properties of biofuel are influenced by structural features of fatty acid such as chain length, degree of unsaturation and branching of the chain. A simple and reliable calculation method to estimate fuel property is therefore needed to avoid experimental testing which is difficult, costly and time consuming. Typically in commercial biodiesel production such testing is done for every batch of fuel produced. In this study 9 different algae species were selected that were likely to be suitable for subtropical climates. The fatty acid methyl esters (FAMEs) of all algae species were analysed and the fuel properties like cetane number (CN), cold filter plugging point (CFPP), kinematic viscosity (KV), density and higher heating value (HHV) were determined. The relation of each fatty acid with particular fuel property is analysed using multivariate and multi-criteria decision method (MCDM) software. They showed that some fatty acids have major influences on the fuel properties whereas others have minimal influence. Based on the fuel properties and amounts of lipid content rank order is drawn by PROMETHEE-GAIA which helped to select the best algae species for biodiesel production in subtropical climates. Three species had fatty acid profiles that gave the best fuel properties although only one of these (Nannochloropsis oculata) is considered the best choice because of its higher lipid content.

Direct conversion of wet algae to crude biodiesel under supercritical ethanol conditions  

Science Journals Connector (OSTI)

Abstract This paper presents a single-step, environmentally friendly approach for the direct conversion of wet algae to crude biodiesel under supercritical ethanol conditions. Ethanol was used for the simultaneous extraction and transesterification of lipids in algae to produce fatty acid ethyl esters at supercritical conditions. In this work the effects of process parameters dry algae to ethanol (wt./vol.) ratio (1:6–1:15), reaction temperature (245–270 °C), and reaction time (2–30 min.) on the yield of fatty acid ethyl esters (FAEE) were studied. 67% conversion was achieved at 265 °C and 20 min of reaction time. The calorific value of a purified biodiesel sample produced at optimum conditions was measured to be 43 MJ/kg, which is higher than that of fatty acid methyl esters produced from the same biomass. The purified fatty acid ethyl esters were analyzed using GC–MS and FTIR. TGA analysis of algal biomass and purified FAEE was presented along with TEM images of the biomass captured before and after supercritical ethanol transesterification. This green conversion process has the potential to provide an energy-efficient and economical route for the production of renewable biodiesel production.

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 overview of palm, jatropha and algae as a potential biodiesel feedstock in Malaysia  

Science Journals Connector (OSTI)

The high demand to replace petroleum fuel makes renewable and sustainable sources such as Palm oil, Jatropha oil and Algae a main focus feedstock for biodiesel production in Malaysia. There are many studies conducted on Palm oil and Jatropha oil, however, the use of Algae as an alternative fuel is still in its infancy. Malaysia already implemented B5 based Palm oil as a feedstock and this biodiesel has been proven safe and can be used without any engine modification. The use of biodiesel produced from these feedstock will also developed domestic economic and provide job opportunities especially in the rural area. In addition, biodiesel has many advantages especially when dealing with the emissions produce as compared to petroleum fuel such as; it can reduce unwanted gases and particulate matter harmful to the atmosphere and mankind. Thus, this paper gathered and examines the most prominent engine emission produced from Palm oil and Jatropha feedstock and also to observe the potential of Algae to be one of the sources of alternative fuel in Malaysia.

Lagooning microbial fuel cells: A first approach by coupling electricity-producing microorganisms and algae  

Science Journals Connector (OSTI)

Abstract The paper focused on the start-up and performance characterisation of a new type of microbial fuel cell (MFC), in which an algae culture was seeded in the cathodic chamber to produce the oxygen required to complete the electrochemical reactions of the MFC, thus circumventing the need for a mechanical aerator. The system did not use mediators or high cost catalysts and it can be started-up easily using a straightforward three-stage procedure. The start-up consists of the separate production of the electricity-producing microorganisms and the algae cultures (stage I), replacement of the mechanical aeration system by the algae culture (stage II) and a change in the light dosage from a continuous input to a dynamic day/night profile. The MFC was operated under a regime of 12 h light and 12 h dark and was also operated in batch and continuous substrate-feeding modes. The same cell voltage was achieved when the cathode compartment was operated with air supplied by aerators, which means that this configuration can perform as well as the traditional one. The results also show the influence of both the organic load and light irradiation on electricity production and demonstrate that this type MFC is a robust and promising technology that can be considered as a first approach to perform a lagooning wastewater treatment with microbial fuel cells.

Microbial fuel cell with an algae-assisted cathode: A preliminary assessment  

Science Journals Connector (OSTI)

Abstract A microbial fuel cell (MFC) with an algae-assisted cathode, i.e., a system where the oxygen required by the cathode is not provided by aeration but by the photosynthetic process of the algae (Chlorella vulgaris), has been studied. The cathode was illuminated for 12 h each day (from 8:00 h to 20:00 h). 25 days was necessary to achieve steady state conditions. The time evolution of dissolved oxygen and cell voltage were assessed over the course of each day. As expected, the dissolved oxygen values were not constant throughout the day, reaching maximum values between 14:00 h and 20:00 h when dark phase reactions began and the algae started to consume oxygen. Cell voltage (Rext 120 ?) followed the same trend as the oxygen profile. The supply of CO2 in the cathode was also studied, and half an hour was enough time to get the system working properly. During the acclimation stage, power density increased up to 13.5 mW m?2 at steady state conditions. However, impedance analysis showed that polarization resistance was higher at the cathode than at the anode. Nevertheless, it can be concluded that the studied system is a feasible method to treat wastewater in a self-sustainable way.

Hydrogen isotope fractionation in algae: III. Theoretical interpretations  

Science Journals Connector (OSTI)

Abstract Hydrogen isotope measurements of lipid biomarkers preserved in sediments are most commonly interpreted as qualitative, rather than quantitative indicators of paleoprecipitation owing to an imperfect knowledge of all factors controlling the isotopic fractionation occurring during biosynthesis. Here, we first offer a brief review of appropriate procedures for preparing enriched isotope substrates for use in tracer studies and outline the approximate ?D threshold at which this transition occurs. We then present new interpretations to explain deviations from common stable isotope effects observed in our previous culture experiments and other studies. We draw particular attention to the disagreement between intercept and slope for product–substrate relationships from those predicted for isotope systems, even when R2 values are high, and attribute it to kinetic isotope fractionation. We demonstrate that reconstructing paleoenvironmental water ?D values by simply adding a ? to measured biomarkers ?D values will result in a bias toward deuterium enriched values. This applies even to implicit reconstructions in the form of qualitative interpretations of measured lipid ?D values as indicators of past hydroclimate. We therefore recommend reconstructing water ?D values from lipid ?D values using fractionation factor (?). We also discuss the apparently contradictory increase in D/H fractionation observed at elevated temperature and suggest that this may be the result of the unique wave-particle duality of hydrogen isotopes, which permits isotopologues to avoid surmounting the activation energy barrier that is necessary in traditional kinetic reactions.

A National-Scale Comparison of Resource and Nutrient Demands for Algae-Based Biofuel Production by Lipid Extraction and Hydrothermal Liquefaction  

SciTech Connect (OSTI)

Algae’s high productivity provides potential resource advantages over other fuel crops. However, demand for land, water, and nutrients must be minimized to avoid impacts on food production. We apply our national-scale, open-pond, growth and resource models to assess several biomass to fuel technological pathways based on Chlorella. We compare resource demands between hydrothermal liquefaction (HTL) and lipid extraction (LE) to meet 1.89E+10 and 7.95E+10 L yr-1 biofuel targets. We estimate nutrient demands where post-fuel biomass is consumed as co-products and recycling by anaerobic digestion (AD) or catalytic hydrothermal gasification (CHG). Sites are selected through prioritization based on fuel value relative to a set of site-specific resource costs. The highest priority sites are located along the Gulf of Mexico coast, but potential sites exist nationwide. We find that HTL reduces land and freshwater consumption by up to 46% and saline groundwater by around 70%. Without recycling, nitrogen (N) and phosphorous (P) demand is reduced 33%, but is large relative to current U.S. agricultural consumption. The most nutrient-efficient pathways are LE+CHG for N and HTL+CHG for P (by 42%). Resource gains for HTL+CHG are offset by a 344% increase in N consumption relative to LE+CHG (with potential for further recycling). Nutrient recycling is essential to effective use of alternative nutrient sources. Modeling of utilization availability and costs remains, but we find that for HTL+CHG at the 7.95E+10 L yr-1 production target, municipal sources can offset 17% of N and 40% of P demand and animal manures can generally meet demands.

Kinetic and thermodynamic studies on biodiesel production from Spirulina platensis algae biomass using single stage extraction–transesterification process  

Science Journals Connector (OSTI)

Abstract Biodiesel production from nonedible feedstocks is gaining attention in the recent years as they do not interfere with the global food economy. In this investigation, Spirulina platensis algae biomass was used as the feedstock for biodiesel production. Single stage extraction–transesterification was carried out with an aim to study the effect of reaction temperature, catalyst concentration, algae biomass to methanol ratio (wt:vol), stirring intensity and algae drying duration on the biodiesel yield. The optimum conditions for maximum biodiesel yield (75 ± 0.40%) were found to be 90 min duration for algae drying, 60% catalyst concentration, 1:4 algae biomass to methanol ratio, 450 rpm stirring intensity and 55 °C reaction temperature. The experimental data appeared to be a good fit with the first order reaction kinetics. For the reaction studied at different temperatures, values of rate constant and activation energy were found out to be 0.001 min?1 and 14518.51 J/mol respectively. The values of thermodynamic parameters such as Gibbs free energy (?G), enthalpy of activation (?H) and entropy of activation (?S) were also determined. The positive values of ?G and ?H and negative value of ?S indicated the unspontaneous and endergonic nature of the reaction.

Surface complexation of neptunium (V) onto whole cells and cell componets of Shewanella alga  

SciTech Connect (OSTI)

We systematically quantified surface complexation of neptunium(V) onto whole cells of Shewanella alga strain BrY and onto cell wall and extracellular polymeric substances (EPS) of S. alga. We first performed acid and base titrations and used the mathematical model FITEQL with constant-capacitance surface-complexation to determine the concentrations and deprotonation constants of specific surface functional groups. Deprotonation constants most likely corresponded to a carboxyl site associated with amino acids (pK{sub a} {approx} 2.4), a carboxyl group not associated with amino acids (pK{sub a} {approx} 5), a phosphoryl site (pK{sub a} {approx} 7.2), and an amine site (pK{sub a} > 10). We then carried out batch sorption experiments with Np(V) and each of the S. alga components at different pHs. Results show that solution pH influenced the speciation of Np(V) and each of the surface functional groups. We used the speciation sub-model of the biogeochemical model CCBATCH to compute the stability constants for Np(V) complexation to each surface functional group. The stability constants were similar for each functional group on S. alga bacterial whole cells, cell walls, and EPS, and they explain the complicated sorption patterns when they are combined with the aqueous-phase speciation of Np(V). For pH < 8, NpO{sub 2}{sup +} was the dominant form of Np(V), and its log K values for the low-pK{sub a} carboxyl, other carboxyl, and phosphoryl groups were 1.75, 1.75, and 2.5 to 3.1, respectively. For pH greater than 8, the key surface ligand was amine >XNH3+, which complexed with NpO{sub 2}(CO{sub 3}){sub 3}{sup 5-}. The log K for NpO{sub 2}(CO{sub 3}){sub 3}{sup 5-} complexed onto the amine groups was 3.1 to 3.6. All of the log K values are similar to those of Np(V) complexes with aqueous carboxyl and N-containing carboxyl ligands. These results point towards the important role of surface complexation in defining key actinide-microbiological interactions in the subsurface.

Optimization of direct conversion of wet algae to biodiesel under supercritical methanol conditions  

Science Journals Connector (OSTI)

This study demonstrated a one-step process for direct liquefaction and conversion of wet algal biomass containing about 90% of water to biodiesel under supercritical methanol conditions. This one-step process enables simultaneous extraction and transesterification of wet algal biomass. The process conditions are milder than those required for pyrolysis and prevent the formation of by-products. In the proposed process, fatty acid methyl esters (FAMEs) can be produced from polar phospholipids, free fatty acids, and triglycerides. A response surface methodology (RSM) was used to analyze the influence of the three process variables, namely, the wet algae to methanol (wt./vol.) ratio, the reaction temperature, and the reaction time, on the \\{FAMEs\\} conversion. Algal biodiesel samples were analyzed by ATR-FTIR and GC–MS. Based on the experimental analysis and RSM study, optimal conditions for this process are reported as: wet algae to methanol (wt./vol.) ratio of around 1:9, reaction temperature and time of about 255 °C, and 25 min respectively. This single-step process can potentially be an energy efficient and economical route for algal biodiesel production.

Lipid content and fatty acid composition of Mediterranean macro-algae as dynamic factors for biodiesel production  

Science Journals Connector (OSTI)

Summary Using the total lipid contents and fatty acid profiles, the marine macro-algae Jania rubens (Rhodophyceae), Ulva linza (Chlorophyceae) and Padina pavonica (Phaeophyceae) were evaluated for biodiesel production during the spring, summer and autumn. Seawater parameters such as pH, salinity and temperature were measured. The total lipid content varied from 1.56% (J. rubens) to 4.14% (U. linza) of dry weight, with the highest values occurring in spring. The fatty acid methyl ester profiles were analysed using gas chromatography. The highest percentage of total fatty acids was recorded in P. pavonica, with 6.2% in autumn, whereas the lowest was in J. rubens, with 68.6% in summer. The relative amount of saturated to unsaturated fatty acids was significantly higher in P. pavonica than in the other macro-algae. Seasonal variations in pH, salinity and temperature had no significant effect on the total lipid and fatty acid contents. Principal component analysis grouped brown and green algae together, whereas red alga grouped out. Furthermore, methyl ester profiles indicate that brown and green seaweeds are preferred, followed by red seaweeds, which appears to have little potential for oil-based products. Therefore, these seaweeds are not targets for biodiesel production.

Process Design and Economics for the Conversion of Algal Biomass to Hydrocarbons: Whole Algae Hydrothermal Liquefaction and Upgrading  

SciTech Connect (OSTI)

This report provides a preliminary analysis of the costs associated with converting whole wet algal biomass into primarily diesel fuel. Hydrothermal liquefaction converts the whole algae into an oil that is then hydrotreated and distilled. The secondary aqueous product containing significant organic material is converted to a medium btu gas via catalytic hydrothermal gasification.

Applied ALARA techniques  

SciTech Connect (OSTI)

The presentation focuses on some of the time-proven and new technologies being used to accomplish radiological work. These techniques can be applied at nuclear facilities to reduce radiation doses and protect the environment. The last reactor plants and processing facilities were shutdown and Hanford was given a new mission to put the facilities in a safe condition, decontaminate, and prepare them for decommissioning. The skills that were necessary to operate these facilities were different than the skills needed today to clean up Hanford. Workers were not familiar with many of the tools, equipment, and materials needed to accomplish:the new mission, which includes clean up of contaminated areas in and around all the facilities, recovery of reactor fuel from spent fuel pools, and the removal of millions of gallons of highly radioactive waste from 177 underground tanks. In addition, this work has to be done with a reduced number of workers and a smaller budget. At Hanford, facilities contain a myriad of radioactive isotopes that are 2048 located inside plant systems, underground tanks, and the soil. As cleanup work at Hanford began, it became obvious early that in order to get workers to apply ALARA and use hew tools and equipment to accomplish the radiological work it was necessary to plan the work in advance and get radiological control and/or ALARA committee personnel involved early in the planning process. Emphasis was placed on applying,ALARA techniques to reduce dose, limit contamination spread and minimize the amount of radioactive waste generated. Progress on the cleanup has,b6en steady and Hanford workers have learned to use different types of engineered controls and ALARA techniques to perform radiological work. The purpose of this presentation is to share the lessons learned on how Hanford is accomplishing radiological work.

Biodiesel production from algae oil high in free fatty acids by two-step catalytic conversion  

Science Journals Connector (OSTI)

The effect of storage temperature and time on lipid composition of Scenedesmus sp. was studied. When stored at 4 °C or higher, the free fatty acid content in the wet biomass increased from a trace to 62.0% by day 4. Using two-step catalytic conversion, algae oil with a high free fatty acid content was converted to biodiesel by pre-esterification and transesterification. The conversion rate of triacylglycerols reached 100% under the methanol to oil molar ratio of 12:1 during catalysis with 2% potassium hydroxide at 65 °C for 30 min. This process was scaled up to produce biodiesel from Scenedesmus sp. and Nannochloropsis sp. oil. The crude biodiesel was purified using bleaching earth. Except for moisture content, the biodiesel conformed to Chinese National Standards.

Production of algae-based biodiesel using the continuous catalytic Mcgyan® process  

Science Journals Connector (OSTI)

This study demonstrates the production of algal biodiesel from Dunaliella tertiolecta, Nannochloropsis oculata, wild freshwater microalgae, and macroalgae lipids using a highly efficient continuous catalytic process. The heterogeneous catalytic process uses supercritical methanol and porous titania microspheres in a fixed bed reactor to catalyze the simultaneous transesterification and esterification of triacylglycerides and free fatty acids, respectively, to fatty acid methyl esters (biodiesel). Triacylglycerides and free fatty acids were converted to alkyl esters with up to 85% efficiency as measured by 300 MHz 1H NMR spectroscopy. The lipid composition of the different algae was studied gravimetrically and by gas chromatography. The analysis showed that even though total lipids comprised upwards of 19% of algal dry weight the saponifiable lipids, and resulting biodiesel, comprised only 1% of dry weight. Thus highlighting the need to determine the triacylglyceride and free fatty acid content when considering microalgae for biodiesel production.

Comparative life cycle assessment of biodiesel from algae and jatropha: A case study of India  

Science Journals Connector (OSTI)

Abstract Algae and jatropha, two types of promising and unconventional biomass, are investigated in this study for large-scale production of biodiesel. The aim is to evaluate the potential advantages and the magnitude of closeness of life cycle balances between these two biodiesel pathways compared to fossil diesel, by taking into account possible uncertainties. The geographical location of this study is India with a prospect of utilizing available wastelands in southern regions. The results indicate that the environmental performance of algal biodiesel is comparable to that of jatropha biodiesel. Both show significant GHG emission and fossil energy depletion reductions which are in the range of 36–40 and 10–25% respectively compared to fossil diesel in the studied geographic context.

Purification and characterization of phycocyanin from the blue-green alga Aphanizomenon flos-aquae  

Science Journals Connector (OSTI)

Aphanizomenon flos-aquae (AFA) is a blue-green alga and represents a nutrient-dense food source. In this study the presence of phycocyanin (PC), a blue protein belonging to the photosynthetic apparatus, has been demonstrated in AFA. An efficient method for its separation has been set up: PC can be purified by a simple single step chromatographic run using a hydroxyapatite column (ratio A620/A280 of 4.78), allowing its usage for health-enhancing properties while eliminating other aspecific algal components. Proteomic investigation and HPLC analysis of purified AFA phycobilisomes revealed that, contrary to the well-characterized Synechocystis and Spirulina spp., only one type of biliprotein is present in phycobilisomes: phycocyanins with no allo-phycocyanins. Two subunit polypeptides of PC were also separated: the ? subunit containing two bilins as chromophore and the ? subunit containing only one.

Siting algae cultivation facilities for biofuel production in the United States: trade-offs between growth rate, site constructability, water availability, and infrastructure  

SciTech Connect (OSTI)

Locating sites for new algae cultivation facilities is a complex task. The climate must support high growth rates, and cultivation ponds require appropriate land and water resources as well as key utility and transportation infrastructure. We employ our spatiotemporal Biomass Assessment Tool (BAT) to select promising locations based on the open-pond cultivation of Arthrospira sp. and a strain of the order Desmidiales. 64,000 potential sites across the southern United States were evaluated. We progressively apply a range of screening criteria and track their impact on the number of selected sites, geographic location, and biomass productivity. Both strains demonstrate maximum productivity along the Gulf of Mexico coast, with the highest values on the Florida peninsula. In contrast, sites meeting all selection criteria for Arthrospira were located along the southern coast of Texas and for Desmidiales were located in Louisiana and southern Arkansas. Site selection was driven mainly by the lack of oil pipeline access in Florida and elevated groundwater salinity in southern Texas. The requirement for low salinity freshwater (<400 mg L-1) constrained Desmidiales locations; siting flexibility is greater for salt-tolerant species such as Arthrospira. Combined siting factors can result in significant departures from regions of maximum productivity but are within the expected range of site-specific process improvements.

Design of an optimal process for enhanced production of bioethanol and biodiesel from algae oil via glycerol fermentation  

Science Journals Connector (OSTI)

Abstract In this paper, we optimize a process that integrates the use of glycerol to produce ethanol via fermentation within the simultaneous production of biodiesel and bioethanol from algae. The process consists of growing the algae, determining the optimal fraction of oil vs. starch, followed by oil extraction, starch liquefaction and saccharification, to sugars, oil transesterification, for which we consider two transesterification technologies (enzymes and alkali) and the fermentation of sugars and glycerol. The advantage of this process is that the dehydration technologies are common for the products of the glucose and glycerol fermentation. Simultaneous optimization and heat integration is performed using Duran and Grossmann’s model. The fermentation of glycerol to ethanol increases the production of bioethanol by at least 50%. The energy and water consumptions are competitive with other processes that either sell the glycerol or use it to obtain methanol. However, the price for the biofuels is only competitive if glycerol cannot be sold to the market.

Investigating Sources of Toxicity in Stormwater: Algae Mortality in Runoff Upstream of the Lawrence Livermore National Laboratory  

SciTech Connect (OSTI)

A source evaluation case study is presented for observations of algae toxicity in an intermittent stream passing through the Lawrence Livermore National Laboratory near Livermore, California. A five-step procedure is discussed to determine the cause of water toxicity problems and to determine appropriate environmental management practices. Using this approach, an upstream electrical transfer station was identified as the probable source of herbicides causing the toxicity. In addition, an analytical solution for solute transport in overland flow was used to estimate the application level of 40 Kg/ha. Finally, this source investigation demonstrates that pesticides can impact stream water quality regardless of application within levels suggested on manufacturer labels. Environmental managers need to ensure that pesticides that could harm aquatic organisms (including algae) not be used within close proximity to streams or storm drainages and that application timing should be considered for environmental protection.

Subcritical water extraction of lipids from wet algae for biodiesel production  

Science Journals Connector (OSTI)

Abstract An energy efficient extraction of algal lipids from wet algal biomass was performed at subcritical conditions of water. This was achieved using microwave assisted heating as well as conventional heating. The conventional heating subcritical water (C-SCW) extraction and microwave assisted subcritical water (MW-SCW) experiments were designed and conducted to study the effects of extraction temperature, time, and biomass loading on lipid extraction. The Response surface methodology was used to optimize the parameters for maximum extraction of lipids. The influence of extraction temperature is more when compared to other experimental parameters in both processes. The maximum extraction efficiencies were achieved at 220 °C using conventional heating and 205 °C using microwave heating. Complete extraction of lipids was observed with microwave assisted heating and 70% extraction efficiency was achieved using conventional heating. The energy required for extraction is greatly reduced (2–8 folds) when compared to the conventional solvent extraction. The potential by-products like protein rich residual algae, omega-3 fatty acids, and sugars in residual water phase were identified. The biomass and the crude extracts were characterized using GC–MS, Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), and thermogravimetric analysis (TGA).

A methodology to assess open pond, phototrophic, algae production potential: A Hawaii case study  

Science Journals Connector (OSTI)

Abstract Geographic information system (GIS) analysis was used to identify lands suitable for open pond production of phototrophic microalgae in the state of Hawaii where rainfall is less than 1.0 m y?1, solar insolation is at least 4.65 kWh m?2 d?1, slope is ?5%, zoning is non-residential, and contiguous area is at least 0.2 km2 (Base Case). Eight sensitivity analyses were performed that varied these criteria and considered an added criterion stipulating a maximum distance from power plants that could serve as CO2 sources. Results were overlaid with GIS layers for agricultural lands of importance to the State of Hawaii and land serviced by freshwater irrigation infrastructure. Base Case conditions were identified on 476 km2, 2.9% of State land area. 60% of Base Case lands are important agricultural lands and of these, half are serviced by irrigation infrastructure. Assumed algae oil productivity of 1.87 dm3 m?2 y?1 would yield 0.9 hm3 y?1, equivalent to 30% of the combined total consumption of distillate and jet fuel in the State in 2011.

Emergence of green business models: The case of algae biofuel for aviation  

Science Journals Connector (OSTI)

Abstract Emergent business models seek to take advantage of new market mechanisms driven by technological changes, particularly those related to the production and delivery of clean or sustainable energy. Such business models often function at the intersection of various industries, with global views, and the resulting systems have distinct social, political, environmental, economic, technological, and business dimensions. Such holistic systems are not only difficult to develop but also require support from a broad range of actors with effective regulations and policies in place, such that the firm functions within a framework that integrates various factors. This study substantiates such a framework by detailing the nascent algae-based bio-fuel industry that caters to the aviation sector while arguing that businesses in the energy industry can emerge as a next-practice platform that drive a sixth wave of innovation. The framework begins with three basic enablers, innovation, flexibility, and sustainability, and explains how value from renewable energy technologies can be created and captured sustainably and innovatively with new market mechanisms implemented by firms with green business models.

Surface Complexation of Neptunium(V) onto Whole Cells and Cell Components of Shewanella alga: Modeling and Experimental Study  

SciTech Connect (OSTI)

We systematically quantified surface complexation of Np(V) onto whole cells, cell wall, and extracellular polymeric substances (EPS) of Shewanella alga strain BrY. We first performed acid and base titrations and used the mathematical model FITEQL to estimate the concentrations and deprotonation constants of specific surface functional groups. Deprotonation constants most likely corresponded to a carboxyl group not associated with amino acids (pK{sub a} {approx} 5), a phosphoryl site (pK{sub a} {approx} 7.2), and an amine site (pK{sub a} > 10). We then carried out batch sorption experiments with Np(V) and each of the S. alga components as a function of pH. Since significant Np(V) sorption was observed on S. alga whole cells and its components in the pH range 2-5, we assumed the existence of a fourth site: a low-pK{sub a} carboxyl site (pK{sub a} {approx} 2.4) that is associated with amino acids. We used the SPECIATE submodel of the biogeochemical model CCBATCH to compute the stability constants for Np(V) complexation to each surface functional group. The stability constants were similar for each functional group on S. alga bacterial whole cells, cell walls, and EPS, and they explain the complicated sorption patterns when they are combined with the aqueous-phase speciation of Np(V). For pH < 8, the aquo NpO{sub 2}{sup +} species was the dominant form of Np(V), and its log K values for the low-pK{sub a} carboxyl, mid-pK{sub a} carboxyl, and phosphoryl groups were 1.8, 1.8, and 2.5-3.1, respectively. For pH greater than 8, the key surface ligand was amine > XNH{sub 3}{sup +}, which complexed with NpO{sub 2}(CO{sub 3}){sub 3}{sup 5-}. The log K for NpO{sub 2}(CO{sub 3}){sub 3}{sup 5-} complexed onto the amine groups was 3.1-3.9. All of the log K values are similar to those of Np(V) complexes with aqueous carboxyl and N-containing carboxyl ligands. These results help quantify the role of surface complexation in defining actinide-microbiological interactions in the subsurface.

Triclosan causes toxic effects to algae in marine biofilms, but does not inhibit the metabolic activity of marine biofilm bacteria  

Science Journals Connector (OSTI)

Abstract Effects of the antimicrobial agent triclosan to natural periphyton communities (biofilms, comprising primarily microalgae and bacteria) were assessed in two independent experiments during spring and summer. For that purpose a semi-static test system was used in which periphyton was exposed to a concentration range of 5–9054 nmol/L triclosan. Effects on algae were analyzed as content and composition of photosynthetic pigments. The corresponding EC50 values were 39.25 and 302.45 nmol/L for the spring and summer experiment, respectively. Effects on periphytic bacteria were assessed as effects on carbon utilization patterns, using Biolog Ecoplates. No inhibition of either total carbon utilization or functional diversity was observed, indicating a pronounced triclosan tolerance of the marine bacteria. In contrast, a small stimulation of the total carbon utilization was observed at triclosan concentrations exceeding 100 nmol/L.

Integration of algae cultivation as biodiesel production feedstock with municipal wastewater treatment: Strains screening and significance evaluation of environmental factors  

Science Journals Connector (OSTI)

The objectives of this study are to find the robust strains for the centrate cultivation system and to evaluate the effect of environmental factors including light intensity, light–dark cycle, and exogenous CO2 concentration on biomass accumulation, wastewater nutrient removal and biodiesel production. The results showed that all 14 algae strains from the genus of Chlorella, Haematococcus, Scenedesmus, Chlamydomonas, and Chloroccum were able to grow on centrate. The highest net biomass accumulation (2.01 g/L) was observed with Chlorella kessleri followed by Chlorella protothecoides (1.31 g/L), and both of them were proved to be capable of mixotrophic growth when cultivated on centrate. Environmental factors had significant effect on algal biomass accumulation, wastewater nutrients removal and biodiesel production. Higher light intensity and exogenous CO2 concentration with longer lighting period promote biomass accumulation, biodiesel production, as well as the removal of chemical oxygen demand and nitrogen, while, lower exogenous CO2 concentration promotes phosphorus removal.

Biodiesel production from algae cultivated in winter with artificial wastewater through pH regulation by acetic acid  

Science Journals Connector (OSTI)

Abstract Algae have been considered as a promising biodiesel feedstock. One of the major factors affecting large-scale algae technology application is poor wintering cultivation performance. In this study, an integrated approach is investigated combining freshwater microalgae Chlorella zofingiensis wintering cultivation in pilot-scale photobioreactors with artificial wastewater treatment. Mixotrophic culture with the addition of acetic acid (pH-regulation group) and autotrophic culture (control group) were designed, and the characteristics of algal growth, lipid and biodiesel production, and nitrogen and phosphate removal were examined. The results showed that, by using acetic acid three times per day to regulate pH at between 6.8 and 7.2, the total nitrogen (TN) and total phosphate (TP) removal could be increased from 45.2% to 73.5% and from 92.2% to 100%, respectively. Higher biomass productivity of 66.94 mg L?1 day?1 with specific growth rate of 0.260 day?1 was achieved in the pH-regulation group. The lipid content was much higher when using acetic acid to regulate pH, and the relative lipid productivity reached 37.48 mg L?1 day?1. The biodiesel yield in the pH-regulated group was 19.44% of dry weight, with 16–18 carbons as the most abundant composition for fatty acid methyl esters. The findings of the study prove that pH adjustment using acetic acid is efficient in cultivating C. zofingiensis in wastewater in winter for biodiesel production and nutrient reduction.

Applying Quantum Principles to Psychology  

E-Print Network [OSTI]

This article starts out with a detailed example illustrating the utility of applying quantum probability to psychology. Then it describes several alternative mathematical methods for mapping fundamental quantum concepts (such as state preparation, measurement, state evolution) to fundamental psychological concepts (such as stimulus, response, information processing). For state preparation, we consider both pure states and densities with mixtures. For measurement, we consider projective measurements and positive operator valued measurements. The advantages and disadvantages of each method with respect to applications in psychology are discussed.

Strain selection, biomass to biofuel conversion, and resource colocation have strong impacts on the economic performance of algae cultivation sites  

SciTech Connect (OSTI)

Decisions involving strain selection, biomass to biofuel technology, and the location of cultivation facilities can strongly influence the economic viability of an algae-based biofuel enterprise. In this contribution we summarize our past results in a new analysis to explore the relative economic impact of these design choices. We present strain-specific growth model results from two saline strains (Nannocloropsis salina, Arthrospira sp.), a fresh to brackish strain (Chlorella sp., DOE strain 1412), and a freshwater strain of the order Sphaeropleales. Biomass to biofuel conversion is compared between lipid extraction (LE) and hydrothermal liquefaction (HTL) technologies. National-scale models of water, CO2 (as flue gas), land acquisition, site leveling, construction of connecting roads, and transport of HTL oil to existing refineries are used in conjunction with estimates of fuel value (from HTL) to prioritize and select from 88,692 unit farms (UF, 405 ha in pond area), a number sufficient to produce 136E+9 L yr-1 of renewable diesel (36 billion gallons yr-1, BGY). Strain selection and choice of conversion technology have large economic impacts, with differences between combinations of strains and biomass to biofuel technologies being up to $10 million dollars yr-1 UF-1. Results based on the most productive species, HTL-based fuel conversion, and resource costs show that the economic potential between geographic locations within the selection can differ by up to $4 million yr-1 UF-1, with 2.0 BGY of production possible from the most cost-effective sites. The local spatial variability in site rank is extreme, with very high and low rank sites within 10s of km of each other. Colocation with flue gas sources has a strong influence on site rank, but the most costly resource component varies from site to site. The highest rank sites are located predominantly in Florida and Texas, but most states south of 37°N latitude contain promising locations.

Prospects for the use of macro-algae for fuel in Ireland and the UK: An overview of marine management issues  

Science Journals Connector (OSTI)

Competing demand for land is driving biofuel and bioenergy research in various directions including macro-algae (seaweed). This paper reviews the main issues for the marine environment of cultivating and harvesting UK and Irish seaweed for biofuels/bioenergy, informed by stakeholder interviews. These showed stakeholders were sceptical of an offshore cultivation industry developing but generally considered inshore cultivation possible, while noting various practical obstacles and conditions. Views on expansion of seaweed harvesting were more divided, with research scientists being relatively cautious.

Application of magnesium sulfate and its nanoparticles for enhanced lipid production by mixotrophic cultivation of algae using biodiesel waste  

Science Journals Connector (OSTI)

Abstract CG (Crude glycerol) is one of the major wastes of biodiesel production process. It can be used as a substrate for lipid production by algae and the produced lipid can be recycled as a feedstock for biodiesel production. In order to avoid substrate inhibition, lipid production media are prepared by diluting the CG with distilled water. However, CG contains only a small amount of Mg (57.41 ± 18 ppm) and its concentration is further decreased to around 0.57 ppm during the dilution process. Apart from having a number of roles in algal physiology, Mg is the central atom of chlorophyll. Therefore, MgSO4 was evaluated as a Mg source to supplement the CG based media used for lipid production by Chlorella vulgaris. By supplementing the process with 1 g/L of MgSO4, nearly 185.29 ± 4.53% improvement in lipid production has been achieved. Further, application of MgSO4 nanoparticles was found to improve the lipid production by 118.23 ± 5.67%. Interestingly, unlike MgSO4, its nanoparticles were found to enhance the lipid production at the expense of only a small amount of glycerol. Thus, application of MgSO4 nanoparticles could be a potential strategy for enhanced lipid yield.

Significant Increase in Hydrogen Photoproduction Rates and Yields by Wild-Type Algae is Detected at High Photobioreactor Gas Phase Volume (Fact Sheet)  

SciTech Connect (OSTI)

This NREL Hydrogen and Fuel Cell Technical Highlight describes how hydrogen photoproduction activity in algal cultures can be improved dramatically by increasing the gas-phase to liquid-phase volume ratio of the photobioreactor. NREL, in partnership with subcontractors from the Institute of Basic Biological Problems in Pushchino, Russia, demonstrated that the hydrogen photoproduction rate in algal cultures always decreases exponentially with increasing hydrogen partial pressure above the culture. The inhibitory effect of high hydrogen concentrations in the photobioreactor gas phase on hydrogen photoproduction by algae is significant and comparable to the effect observed with some anaerobic bacteria.

Hydrothermal liquefaction of four brown macro-algae commonly found on the UK coasts: An energetic analysis of the process and comparison with bio-chemical conversion methods  

Science Journals Connector (OSTI)

Abstract Hydrothermal liquefaction (HTL) of four brown macro-algae was used to produce bio-crude and bio-char in an energy favorable way. Bio-crude yields between 9.8 wt% and 17.8 wt% (daf) with \\{HHVs\\} between 32 and 34 MJ/kg and bio-char yields between 10.9 wt% and 18.6 wt% (db) with \\{HHVs\\} between 15.7 and 26.2 MJ/kg were produced. A modification of the energy consumption ratio (ECR) index was attempted in order to include in the formula the calculation of the specific heat capacity of the feedstock used, as well as the increase of the specific heat capacity of water with temperature. A comparison in terms of energy output was made between the products from HTL and products from bio-chemical conversion of macro-algae such as anaerobic digestion (AD) and fermentation. The results indicate that HTL has higher energy output than fermentation and analogue of that from anaerobic digestion (7.91 MJ/kgseaweed and 8.25 MJ/kgseaweed from HTL and AD respectively).

Economic comparison of open pond raceways to photo bio-reactors for profitable production of algae for transportation fuels in the Southwest  

Science Journals Connector (OSTI)

As energy prices climb there is an increasing interest in alternative, renewable energy sources. One possible source of renewable bio-fuel is algae. This research uses a multi-year, Monte Carlo financial feasibility model to estimate the costs of production and chance of economic success for commercial size algal biofuel facilities in the Southwest. Capital and operating costs and productivity information from Davis et al. were used to develop parameters to define and simulate two types of algae production systems; open pond and photo-bioreactor (PBR). The financial feasibility of \\{PBRs\\} is substantially lower than for open ponds. In the base case, average total costs of production for lipids, including financial costs, were $12.73/gal and $31.61/gal for open ponds and PBRs, respectively. The chance of economic success for the base situation was zero for both open ponds and PBRs. The financial feasibility analysis showed that the only way to achieve a 95% probability of economic success in the PBR system was to reduce CAPEX by 80% or more and OPEX by 90% or more. For the open pond system there were several options that could return a 95% or greater chance of economic success, for example, reducing CAPEX by 60% and OPEX by 90%.
