ScienceDaily (July 29, 2009) — Using electrolyzed water rather than harsh chemicals could be a more effective and environmentally friendly method in the pretreatment of ethanol waste products to produce an acetone-butanol-ethanol fuel mix, according to research conducted at the University of Illinois.
When ethanol is produced, distiller's dried grain with solubles (DDGS) is a waste product. The DDGS is primarily used as animal feed, but researchers are searching for ways to extract the sugar and ferment it to produce an acetone-butanol-ethanol fuel mix. One obstacle has been in the production phase called pretreatment.

NextGen Biofuels Inc. and Iowa State University will conduct cofiring trials with coal, wood chips and wood pellets at ISU’s coal-fired combined-heat-and-power (CHP) plant, as the school contemplates switching to a biomass-coal blend.
Instead of spending millions on retrofitting, the project is designed to evaluate the efficiency of burning biomass in an existing coal boiler. “We’re trying to demonstrate that you can run wood biomass through a currently operating coal plant,” said Bob Ravlin, president of NextGen. The fuel does, however, need to be tailored to the boiler type, he added. NextGen procured pine wood pellets and wood chips from Rocky Mountain Pellet Company in Colorado for the 3½-month tests, which were supposed to start June 21, but have been postponed because of wet weather and will begin June 28, Ravlin said.

With their extreme versatility and often complicated nature, it isn’t easy for most people to wrap their brain around advanced biofuels, and the definitions in the renewable fuels standard 2 (RFS2) aren’t much help.
When Congress released RFS2, which was signed into law in December 2007 as part of the Energy, Independence & Security Act of 2007, biofuel volume requirements were separated into three categories: advanced biofuels, cellulosic biofuels and biomass-based diesel. An advanced biofuel is defined as a renewable fuel—other than ethanol derived from corn starch—that is derived from renewable biomass and achieves a 50 percent greenhouse gas (GHG) reduction. A cellulosic biofuel is defined as a renewable fuel derived from any cellulose, hemicellulose or lignin that is derived from renewable biomass achieving a 60 percent GHG emission reduction. The potentially perplexing factor is that some cellulosic biofuels won’t meet the 60 percent GHG threshold but will meet the 50 percent threshold, and will therefore count as an advanced biofuel. In addition, though biomass-based diesels are advanced biofuels, the advanced biofuel quantity is reserved for biofuels outside of the cellulosic biofuel and biomass-based diesel subsets, such as sugarcane ethanol.

A few days have now passed since the USDA released its “Regional Roadmap,” outlining a plan to meet the biofuels goals in the Renewable Fuels Standard by 2022.
Industry reaction has been, to date, tepid, to what has been dubbed the “Grasstopia” envisioned in the USDA plan.
First of all — the good news, which is to say generally positive reaction to the idea that the USDA has undertaken a more detailed study of the target at all.
A general criticism is that the plan’s weakness is that it could have been written in 2007, given that it focuses almost exclusively on cellulosic ethanol from energy grasses. Algae as a feedstock, biobutanol or drop-in fuels as products, were left out of the targets – though nearly 75 percent of planned advanced biofuels production is in these forms.

New reports surface almost daily that add to ethanol’s credibility as a fully viable energy alternative. Last week at the International Fuel Ethanol Workshop, POET – the world’s largest ethanol producer – shared the results of an independent lifecycle analysis which concluded that ethanol produced by Project LIBERTY (POET’s first planned cellulosic ethanol plant) will reduce carbon emissions by 111% over gasoline.
This means that POET’s cellulosic ethanol actually results in negative emissions – offsetting more greenhouse gas emissions than it produces. And a new report released by the United States Department of Agriculture (USDA) concludes that current ethanol plants yield “a substantial net energy gain.”

WASHINGTON June 23 (Reuters) - U.S. environmental regulators have delayed decisions on whether to allow higher concentrations of ethanol in gasoline, a blow to ethanol producers who face a glut of supply but a relief to automakers who fear ethanol will harm engine parts.
Ethanol makers and farmers had expected the Environmental Protection Agency to decide in July whether to allow an increase in the blend rate of ethanol in gasoline to 15 percent from 10 percent for cars built after 2001.
Instead the EPA said last week it would not decide until late September whether to allow cars made after 2007 to burn the higher blend [ID:nN17261431] and that decisions on older cars -- the bulk of the U.S. auto fleet -- would come later.

The University of Missouri is creating initiatives to help develop biomass market in the state.
Biomass has been in use at the University of Missouri power plant since 2005. The power plant boilers have been cofiring wood waste up to 5 percent with coal in the existing plant boilers, consuming between 5,000 and 6,000 tons of woody biomass this year.
So far, using biomass as an alternative fuel source has had a positive impact on the university campus. Overall, greenhouse gas emissions have been reduced by 7,000 tons per year and the reduction in carbon dioxide emissions is equivalent to planting 28,000 acres of trees. In addition, by sourcing locally grown biomass, the university has reduced diesel fuel consumption by almost 16,000 gallons per year that would have been used to transport coal to the power plant from neighboring Illinois.

In Washington, the USDA released its highly-anticipated “Regional Roadmap to Meeting the Biofuels Goals of the Renewable Fuels Standard by 2022.” In the 21-page document, which can be downloaded via biofuelsdigest.com, the USDA identified dedicated energy crops, primarily switchgrass, as the practical platform for achieving a 20 billion gallons of advanced biofuels production, and discussed the regions in which it believed biofuels feedstock production would be most viable, driving the location of bioenergy facilities.
The USDA projected in its report that the US, in order to meet its 2022 RFS target of 36 billion gallons of renewable fuel, would produce 13.4 billion gallons formed educated energy crops, including perennial grasses, energy cane, and biomass sorghum; 500 million gallons from oilseed crops, 4.3 billion gallons from crop residues (corn stover, straw), 2.8 billion gallons from woody biomass (logging residues only) and 15 billion gallons from corn starch ethanol.

Last month in this column, Biomass Thermal Energy Council Chairman Charlie Niebling outlined the recent progress to raise the profile of biomass heating at the national level. However, on April 29, the industry was confronted with a major challenge. Because of action brought by the Sierra Club and other petitioners, the U.S. EPA proposed new emissions regulations. The proposed regulations would impact existing and new commercial, industrial and institutional boilers burning coal, oil and biomass. BTEC sympathizes with the need to decrease emissions of hazardous air pollutants (HAP) and believes the best way to achieve this is through the application of practical performance testing and maintenance regimes that achieve significant emissions reductions without burdening boiler owners, especially small-scale ones, with onerous compliance costs.

The ethanol by-product known as dried distillers grains, or DDGs, is being fed more often these days to all types of livestock. At first, it was mainly beef and dairy cattle producers that utilized the product, which is rich in protein, fiber and oil. Now more hog producers are using the product, which serves to recapture about one third of the corn that goes into making ethanol for the livestock feed market. Each bushel of grain used in the ethanol-making process produces about 18 pounds of DDGS.
Companies like Novus International are helping to increase the use of DDGs in pork production by researching how much DDGs can be included in hog rations at different ages for proper nutrition. “We’ve increased the inclusion rates of distillers from just a few years ago, somewhere around ten percent, now to 30-40 percent in some diets,” says Brad Lawrence, Technical Manager for the Novus pork business in North America.

...for Biosynthesis of Hydrocarbon Fuels; Engineered E. Coli Produces Long-chain Alkenes
The bacterium Micrococcus luteus harbors a three-gene cluster that encodes for enzymes essential to the synthesis of alkenes. (Image courtesy of the Centers for Disease Control and Prevention.) Click to enlarge.
Researchers with the US Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) have identified a trio of bacterial enzymes that can catalyze key steps in the conversion of plant sugars into hydrocarbon compounds for the production of renewable transportation fuels.
Harry Beller, an environmental microbiologist who directs the Biofuels Pathways department for JBEI’s Fuels Synthesis Division, led a study in which a three-gene cluster from the bacterium Micrococcus luteus was introduced into the bacterium Escherichia coli. The enzymes produced by this trio of genes enabled the E. coli to synthesize from glucose long-chain alkene hydrocarbons, predominantly 27:3 and 29:3 (no. carbon atoms: no. C=C bonds).

Reducing emissions by more than a third by 2030 is compatible with GDP and job growth
Brasilia - infoZine - Brazil could reduce its gross greenhouse gas emissions (GHG) by up to 37 percent between 2010 and 2030, while at the same time maintaining the development goals set out by the government for that period, without negatively affecting growth or jobs, says a new World Bank study of low carbon development scenarios in Brazil. This would be the equivalent of taking all of the world’s cars out of circulation for three years. The study was launched today, in Brazil’s capital Brasilia, during a seminar attended by several ministries and research centers.
“Brazil is one of the leading nations at climate negotiations, it has one of the cleanest energy matrixes and is offering creative and constructive solutions both at the global and national levels, as is demonstrated by our voluntary commitment to reduce emissions by between 36.1% and 38.9% by 2020,” said Izabella Teixeira, Environment Minister. “This study joins a list of others proving Brazil’s potential. However, our 2005 emissions represented barely 6.6% of total global emissions. The developed world is responsible for the largest share, and needs to contribute directly and proportionally to the solution of this problem.”

One of the largest ethanol producers in the world has said it has developed a process to produce cellulosic ethanol that has negative emissions.
POET, the company based in Sioux Falls, South Dakota, said its Project LIBERTY has produced a biofuel that actually offsets more greenhouse gas emissions than it generates.
The fuel from POET’s first commercial cellulosic ethanol plant in Scotland, South Dakota, reduced carbon emissions by 111% compared to gasoline.
The results came from an analysis carried out by Air Improvement Resource, Inc., of Novi, Michigan.

A major association representing ethanol manufacturers is furious that the Environmental Protection Agency has delayed making a decision on whether to allow the ethanol content in gasoline to be increased to 15 percent, from 10 percent. But those worried that the increase will damage existing engines applauded the agency’s decision.
The request was made in March 2009 by Growth Energy, an ethanol lobbying group.
Originally a decision by the E.P.A. was expected last December. However, in December the agency said more study was needed and a decision would come in “mid-2010.”

“Lignin is nature’s plastic and any organism that wants to get to the sugars in a plant has to be able to get past this protective barrier,” professor Ming Tien of Penn State.
There’s lignin, lignin everywhere. Next to cellulose, it is the second most abundant organic material on Earth, representing 24-35 percent of softwood weight and 17-25 percent of hardwoods. That’s around 135 billion tons of lignin
Generally, when we use lignin at all, we use it for burning., By and large, it has similar moisture and BTU values as coal (in the 11-12,000 Btu/lb range) with a low ash content. With Central Appalachian coal in the $65/ton range, it’s a low value product at around 3 cents per pound.

In Minnesota, researchers at the University of Minnesota, publishing in the 2010 March-April issue of the Agronomy Journal, have demonstrates that hill slope processes influence biomass productivity. The study focused on seven varying landscape positions to represent a range of topographical features common to the region with varying soil moisture and erosion characteristics. Within each landscape position, a series of woody and herbaceous annual and perennial crops were planted. Crops included alfalfa, corn, willow, cottonwood, poplar, and switchgrass.
Corn grain and stover yield was lowest in flat and depositional areas that retain water for longer periods of time and highest on well drained summit positions. Corn grain yield was not significantly influenced by any of the soil or terrain attributes tested, but corn stover yield was positively influenced by nitrogen, soil darkness profile, and terrain slope.

SDSU researchers studied the impact of integrating production systems that involve ethanol, corn production and cattle. The researchers have a fact sheet that explains their findings.
BROOKINGS, S.D. - South Dakota State University research suggests there's an economic opportunity for corn producers willing to explore integrated production systems that will background beef calves while producing corn to supply ethanol plants.
The numbers based on regional data suggest corn farmers in South Dakota and neighboring states using such integrated production systems can produce 383 gallons of ethanol per acre from their corn crop, as well as backgrounding 760 pounds of beef. The linked production system is also better for soil sustainability and will help the producer's bottom line by saving on fertilizer costs.

The ethanol industry has for years draped itself with the American flag, positioning itself as a cleaner, homegrown alternative to oil. Never has that been more true than today.
With regulators and legislators poised to decide issues that will shape ethanol's future for years to come, the ethanol lobby is increasingly making the scene unfolding in the Gulf of Mexico — with tens of thousands of barrels of crude still flowing daily from BP's deepwater well — a backdrop for the nation's energy debate.

WASHINGTON — The Environmental Protection Agency says it will wait until this fall to decide whether U.S. car engines can handle higher concentrations of ethanol in gasoline.
The agency had been expected to decide by this month whether to increase the maximum blend from 10 to 15 percent.
The EPA said Thursday that initial tests "look good" and should be completed by the end of September. A decision will come after the Energy Department completes the testing of the higher blend on vehicles built after 2007.
ScienceDaily (June 7, 2010) — A new article in the Journal of the American Chemical Society (JACS) describes how nanoparticles formed by very small numbers of silver atoms can protect against the cell damage caused by ethanol.
The study was led by researchers from the University of Barcelona and conducted in conjunction with the Magnetism and Nanotechnology laboratory of the University of Santiago de Compostela.
"The results of the study show that these clusters of small numbers of silver atoms catalyze ethanol oxidation at similar concentrations to those found in the blood of alcoholics and at values of membrane potential and pH that are compatible with those exhibited by mammalian cells," explains Gustavo Egea, a professor with the Department of Cell Biology, Immunology and Neurosciences of the Faculty of Medicine at the UB and an affiliated researcher for the Institute of Nanosciences and Nanotechnology (IN2UB) and the August Pi i Sunyer Miomedical Research Institute (IDIBAPS).

MADISON, Wis. - Researchers have taken a major step forward in cracking the genetic secrets that would make it easier and cheaper to convert tons of Midwest biomass into energy. A team at the Great Lakes Bioenergy Research Center (GLBRC) has found a way to identify specific genetic factors that could lead to less expensive biofuel production.
Scientist David Keating of the University of Wisconsin led the team that has figured out a way to "turn off" certain genetic switches, one at a time, to determine a way to produce a bacterium that can turn crop waste into fuel.
"If we disrupt that gene and now the organism can't degrade this material, we know that gene is really important and that's a gene we want to study further."

... Will Reduce GHG Emissions 111% Over Gasoline
Cellulosic ethanol produced by grain ethanol producer POET’s Project LIBERTY (earlier post) first commercial cellulosic ethanol plant will reduce greenhouse gas emissions (GHG) by 111% relative to gasoline, an independent lifecycle analysis (LCA) compiled by Air Improvement Resource, Inc., has found. (I.e., the cellulosic ethanol will offset more greenhouse gas emissions than it produces.)
The reduction is somewhat less than the 130% calculated by the Environmental Protection Agency (EPA) in the RFS2 for the production of cellulosic ethanol from corn stover using a biochemical process. Air Improvement’s estimates of emissions from Project LIBERTY’s fuel and feedstock transport and fuel production (the last being the sum of storage, electricity, chemicals, waste disposal, and biogas production) are slightly higher than the corresponding elements in EPA’s analysis.

EPA study confirms comprehensive climate and energy legislation is affordable, equitable, and effective

Posted June 15, 2010 in Solving Global Warming
The Environmental Protection Agency (EPA) published an analysis today of the economic impact of the American Power Act (APA), released by Senators Kerry and Lieberman mid-May. The study finds that climate protection is very affordable. For a modest investment the APA would anchor a global effort that could dramatically reduce the risk of catastrophic global warming.
The study includes estimates of what it calls “household costs.” I prefer to call these “investment costs,” since we expect benefits from climate protection.
EPA finds that American households would need to invest on average $79 to $146 per year (51 to 95 cents per day) through 2050 for climate protection. At the same time, the results indicate that, on average, median household income will be $4,893 to $6,497 higher than today’s levels.

Environmental Working Group Report Says Taxpayers Seeing Little Benefit From Government Investment in Ethanol

Washington—Between 2005 and 2009, U.S. taxpayers spent a whopping $17 billion to subsidize corn ethanol blends in gasoline.
What did they get in return?
A reduction in overall oil consumption equal to an unimpressive 1.1 mile-per-gallon increase in fleet-wide fuel economy.
Worse, ethanol’s much ballyhooed contribution to reducing America’s dependence on imported oil looks even smaller – the equivalent to a measly six tenths of a mile per gallon fleet-wide.

Digest readers who closely analyze the Advanced Biofuels Tracking Database will have noticed that, commencing in 2012, biobutanol is scheduled to grow rapidly from pilot stage today to more than 500 million gallons in production by 2014. That’s about 60 percent more butanol by 2014 than the entire US biodiesel market today.
Not to mention that biobutanol has become one of the “now” darlings of the DOE — which has been looking for early “wins” from its round of integrated bioenergy facility grants and sees biobutanol as a sector that will gain traction and find financing the fastest.

South Dakota State University research shows a traditional Asian flatbread called chapathi, or chapati, gets a big boost in protein and fiber when fortified with food-grade distillers grains.
SDSU food scientist Padu Krishnan said it is one example of the ways in which distillers dried grains with solubles, or DDGS, can help improve human nutrition worldwide. DDGS is produced as a co-product when processing corn into ethanol, so corn producers from the American Midwest and elsewhere could tap a vast new market if manufacturers begin using it to fortify products in human diets.
Krishnan and his student, Sowmya Arra, worked with Kurt Rosentrater of the USDA Agricultural Research Service’s North Central Agricultural Research Laboratory on the project. In lab studies they found that using DDGS to make up 10 percent of the dough in chapathi, an Asian whole wheat unleavened bread eaten in South Asia and East Africa, boosted the fiber from 2.9 percent to 7.8 percent. Using 20 percent DDGS in the dough increased the fiber to 10.3 percent.

Forested regions around the world are pursuing biomass as a renewable energy source but a study finds that the carbon footprint from burning biomass can be worse for global warming than coal.
The Manomet Center for Conservation Sciences on Thursday published the findings of a six-month study to measure the greenhouse gas impacts of using biomass, which, in many cases, does not meet claims of being "carbon neutral" over short periods of time.
The report was commissioned by the Massachusetts Department of Energy Resources, which said it will revise its regulations in response. "We can begin the process of refining our renewable energy regulations to provide incentives only for biomass energy that truly reduces our greenhouse gas emissions and protects our forests," said Massachusetts Department of Energy Resources Commissioner Phil Giudice, in a statement.
May 27, 2010 (PhysOrg.com) -- A new University of Illinois at Chicago study of facilities that produce most of the nation's ethanol found that the energy needed to make a gallon of the corn-based fuel decreased on average by about 30 percent within the past decade.
Steffen Mueller, principal research economist at UIC's Energy Resources Center, surveyed the nation's 150 "dry mill" ethanol plants -- the type that produce about 85 percent of the ethanol for energy use -- between November 2009 and January 2010.
The findings may prove useful to state and federal energy policy makers studying the pros and cons of fuels based on their "full life-cycle" -- the total energy needed to create a fuel compared to its energy output, the greenhouse gases emitted during production, the water used in production, and other factors.
"Policy makers rightfully pay attention to life cycle greenhouse gas emissions of fuels," said Mueller. "Biofuel refineries, including corn ethanol plants, are in a rapid innovation phase."

MADISON — A research team at the DOE Great Lakes Bioenergy Research Center (GLBRC) has developed a powerful new tool that promises to unlock the secrets of biomass degradation, a critical step in the development of cost-effective cellulosic biofuels. The details of this method were published online on June 11 in the journal Applied and Environmental Microbiology.
Fulfilling the promise of cellulosic biofuels requires developing efficient strategies to extract sugar molecules in biomass polymers like cellulose. Microorganisms such as bacteria and fungi are capable of converting biomass to simple sugars, but historically have been difficult to study using genetic approaches.
A breakthrough by a team of University of Wisconsin-Madison researchers at the GLBRC has made it possible to perform genetic analysis on Cellvibrio japonicus, a promising bacterium that has long been known to convert biomass to sugars. Using a technique called vector integration, the team has developed a method to generate a mutation in any gene within the organism.
Novozymes, maker of biofuel enzymes, announced the launch of a new enzyme that makes it possible to produce more ethanol from the same amount of corn. The product, Spirizyme Excel, converts more starch in corn, wheat, and other feedstocks into sugars which can be fermented to ethanol, thereby allowing producers to increase yields by more than one percent. Compared to other available solutions, a typical ethanol plant can gain $1 million or more per year using the enzyme, the company said.

DECATUR, Ill. --Archer Daniels Midland Company said Monday it will ask the Environmental Protection Agency to approve ethanol-gasoline blends containing up to 12 percent ethanol for all cars.
The agribusiness company said it still supports a long-term effort to require a 15 percent ethanol blend, but it's unclear if older cars can run efficiently on the stronger 15-percent formula.

More than enough biomass is available surrounding the Charter Street Heating Plant on the University of Wisconsin-Madison campus to provide a supply if the coal plant converts, according to the Wisconsin Bioenergy Initiative. The WBI issued a request for information (RFI) from biomass producers, aggregators, equipment producers and transportation companies, the results of which look promising.

In Pennsylvania, researchers have identified new corn genes that increase the export of carbohydrates from corn leaves and could result in higher yields for biofuels. The two genes that were isolated are controlling the movement of carbon from leaves to other parts of the plant, and thereby control carbohydrate creation.
The researchers, working under a USDA Agriculture and Food Research Initiative, believe that manipulation of the metabolic pathway will give options for increased food or fuel from the plant.
8 June 2010 - The Environmental Protection Agency (EPA) proposed new Boiler Maximum Achievable Control Technology (MACT) standards which would classify biomass boiler units, conventionally considered multi-fuel boilers, as incinerators and would be subject to new emission limits for mercury, hydrogen chloride, particulate matter, carbon monoxide and dioxin. The new proposed ruling is originally part of the Clean Air Act of 1990.
The Biomass Power Association (BPA), a group of 80 plants in 20 states, voiced their concerns during a June 8 teleconference from Washington D.C. BPA President Bob Cleaves said that boilers used by industrial, commercial and institutional facilities use various fuels and the fuels are used to generate various forms of energy such as steam, heat and electricity to be used in manufacturing or the generation of power that is sent to the grid.
If the new rule is enacted, Cleaves believes that 100 percent of boilers in the U.S. will have to do more work emitting less pollutants even though they are currently well controlled. Early estimates have shown that it could cost the biomass industry up to $7 billion to comply with EPA’s new standards.

Forest advocacy groups from three continents are warning that bioenergy poses a threat to forests and forest-dependent peoples, and that IS plans for wood-based bioenergy will worsen a dangerous situation.
Increased support for the burning of wood to produce bioenergy is triggering increased logging and expansion of industrial tree plantations in the USA, Ghana, the Congo, Brazil and West Papua, explains the report, Wood-based Bioenergy: The Green Lie.
The report was released by Global Justice Ecology Project, Global Forest Coalition and Biofuelwatch at the UN climate talks in Bonn, Germany. They claim their call for an immediate end to wood subsidies and incentives for industrial bioenergy is supported by 90 organisations around the world.

Michigan State University and the University of Wisconsin have received $50 million in funding for the Great Lakes Bioenergy Research Center. The Center, a co-hosted facility between the two universities, received the funding from the U.S. DOE. The main goal of the center is to improve second generation biofuel feedstocks for ethanol production, including everything from genetic improvement of the biomass, processing technologies and environmental sustainability.
Spread over a period of five years, a significant portion of the funding has already been used to speed up and bolster this research, said Steven Pueppke, director of MSU’s office of Biobased Technologies. “This additional funding to MSU does have broader ramifications,” said Pueppke. “I do not have exact job numbers, but I know that several hundred direct jobs have been created by the Great Lakes Bioenergy Research Center.” Along with job creation, Pueppke said the funding helps with future biofuels job growth. “The new funding is good, too, in that it attracts bright young scientists into biofuels research. We are happy that this opportunity is at MSU, and we hope that they will make career-long contributions in addressing the nation’s biofuels needs.”

BLACKSBURG — Researchers at Virginia Tech are using science to control unstable components in biomass to develop stable oils that can be readily upgraded to transportation fuels for the first time. Biomass comprises recently living organisms such as wood or waste products.
Converting woody feedstocks – in this case, poplar and pine wood – to liquid fuels usually produces bio-oil that is unstable and acidic, and which cannot be converted to transportation fuel using traditional processing technologies.
According to Foster Agblevor, associate professor of biological systems engineering in the College of Agriculture and Life Sciences, these bio-oils present further problems. The oils become thicker during storage, resulting in a substance that turns to char when heated. These bio-oils are unusable for fuel after only a few months in storage.

A bioenergy technology developed by Australian scientists uses supercharged photosynthesis – the natural process of plants converting sunlight and CO2 into biomass and usable energy – increasing its potential for bioenergy generation.
Executive Director of BioSciences Research at the Department of Primary Industries (DPI) in Victoria, Australia, Professor German Spangenberg, says photosynthetic cells for fructan biosynthesis in popular forage grasses has been reprogrammed, leading to some “remarkable results.”
“By applying this technology to temperate grasses such as perennial ryegrass and tall fescue in glasshouse and field trials, we have shown significantly higher dry matter yields. Recent trials have recorded a doubling of plant biomass double compared to existing varieties,” Professor Spangenberg says.

Biomass facilities have become a more attractive investment than wind and solar technologies, according to the renewable energy sector.
The annual survey of global renewable energy mergers and acquisitions (M&A) by KPMG International indicates that 37% of respondents intend to invest in biomass, while 36% want to invest in solar and 35% in wind energy.
The M&A market increased 145% in deal volume in the first quarter of this year against 2009, with a 63% increase in value. It is expected that many start-up small firms in the renewable energy sector, which have limited finances but have survived the economic recession, may face the prospect of being bought up by another company this year or not surviving due to their frailty.

Scientists urge caution after finding that insects fall into 'ecological trap' by mistaking panels for pools of water
Solar panels could wipe out fragile populations of insects, according to a new study that raises fresh doubts about the ecological impact of some forms of renewable energy.
Scientists have discovered that aquatic insects such as the mayfly can mistake shiny photovoltaic panels for pools of water, which they rely on to reproduce. They urge caution on the increasing use of panels until experts work out how they could affect insects and other creatures that feed on them.

West Lafayette, Indiana - Purdue University scientists have improved a strain of yeast that can produce more biofuel from cellulosic plant material by fermenting all five types of the plant's sugars.
Nathan Mosier, an associate professor of agricultural and biological engineering; Miroslav Sedlak, a research assistant professor of agricultural and biological engineering; and Nancy Ho, a research professor of chemical engineering, used genes from a fungus to re-engineer a yeast strain Ho developed at Purdue. The new yeast can ferment the sugar arabinose in addition to the other sugars found in plant material such as corn stalks, straw, switchgrass and other crop residues.
"Natural yeast can ferment three sugars: galactose, manose and glucose," Ho said. "The original Ho yeast added xylose to that, and now the fifth, arabinose, has been added."

CHAMPAIGN, lll. — Researchers at the University of Illinois have developed a new, more accurate method of calculating the change in greenhouse gas emissions that results from changes in land use.
The new approach, described in the journal Global Change Biology, takes into account many factors not included in previous methods, the researchers report.
There is an urgent need to accurately assess whether particular land-use projects will increase or decrease greenhouse gas emissions, said Kristina Anderson-Teixeira, a postdoctoral researcher in the Energy Biosciences Institute at Illinois and lead author of the new study. The greenhouse gas value (GHGV) of a particular site depends on qualities such as the number and size of plants; the ecosystem’s ability to take up or release greenhouse gases over time; and its vulnerability to natural disturbances, such as fire or hurricane damage, she said.

Abstract. Use of biofuels does not reduce emissions from energy combustion but may offset emissions by increasing plant growth or by reducing plant residue or other non-energy emissions. To do so, biofuel production must generate and use `additional carbon', which means carbon that plants would not otherwise absorb or that would be emitted to the atmosphere anyway. When biofuels cause no direct land use change, they use crops that would grow regardless of biofuels so they do not directly absorb additional carbon. All potential greenhouse gas reductions from such biofuels, as well as many potential emission increases, result from indirect effects, including reduced crop consumption, price-induced yield gains and land conversion. If lifecycle analyses ignore indirect effects of biofuels, they therefore cannot properly find greenhouse gas reductions. Uncertainties in estimating indirect emission reductions and increases are largely symmetrical. The failure to distinguish `additional' carbon from carbon already absorbed or withheld from the atmosphere also leads to large overestimates of global bioenergy potential. Reasonable confidence in greenhouse gas reductions requires a precautionary approach to estimating indirect effects that does not rely on any single model. Reductions can be more directly assured, and other adverse indirect effects avoided, by focusing on biofuels from directly additional carbon.

PITTSBURGH (Reuters) – President Barack Obama pledged on Wednesday to find Senate support for a bill to overhaul U.S. energy policy and called for an end to oil company tax breaks in the wake of the Gulf of Mexico spill.
Ethanol has been slowly adopted, helped by various tax credits and incentives that will continue to exist for years to come. That is the upshot of a new study on ethanol and biofuels which provides policy makers with instant feedback about their decisions.
Ethanol and biofuels policies have been analyzed by the Food and Agricultural Policy Research Institute at the University of Missouri to determine the impact of biofuels policy in 10 years, depending upon what was decided. Their analysis keeps today’s basis policies in place, not only the ethanol supports, but also the biodiesel credit that expired in December.
The growth of ethanol soon begins to slow down, but 15 billion gallons will be produced in 2015 when other types of ethanol gain a foothold. Because of the upper limit for corn use in ethanol production, imported sugar begins to see significant use.

Bioenergy companies are increasing, yet securing funding may be challenging for this highly unproven and untested technology
Due to the economic downslide of recent years, finding funding for renewable energy projects is harder than ever. The current trend in the sustainable energy sector involves companies virtually waiting for the right kind of financing to come through for their projects. Whether they end up being funded by the federal government, state grants or bank-financed loans, a lot of environmental-development projects are being put on the back burner until the economy bounces back. For small businesses to get the right financing from banks, the banks also want to see evidence that these bioenergy companies will be successful. But it is hard to prove something like that when the bioenergy revolution is fairly new and hasn’t gained much exposure. In addition, these small businesses don’t have the funds to advertise or really make themselves known. While banks are interested in advanced environmental technologies to some degree, they are also hesitant to invest in a startup venture involving bioenergy—these projects are viewed as being a high risk in the eyes of most banks.

Can biofuels find the path to petroleum parity?
While the technical and cost potential of bio-products to compete with petroleum grows, can they match its giant scale? Mark Bünger explains why massively ramping up output will be the biggest challenge for bioenergy.
Petroleum-based products such as fuels and plastics are vilified for their economic and environmental drawbacks. Businesses, scientists and governments are urgently seeking a reliable supply of affordable fuels and industrial materials, and a reduction in the amount of carbon dioxide entering the atmosphere, and are looking to bio-based products to deliver them.
However, even as they seek to mitigate its drawbacks, they want to match oil's primary benefit – the availability of a large quantity of versatile, valuable material.
To date, most biofuels and biomaterials developers have focused on lab- and demo-scale studies to improve performance and reduce cost so they can compete with petroleum products, and those goals are coming within sight.

In Washington, the Renewable Fuels Association issued a white paper on gasoline and ethanol prices, concluding that “the average American household is saving approximately $200‐400 per year on gasoline because of the inclusion of ethanol in the U.S. fuel supply.” The RFA cites the ethanol blenders tax credit, and the spread between ethanol and gasoline prices as the underlying cause.
Opponents of ethanol have responded that gasoline savings are offset by increases in taxation and the cost of ethanol.

The National Science Foundation (NSF) will provide $2.65 million grant to team Michigan State University (MSU) graduate students with K-12 science teachers from 11 area school districts. This new GK-12 Bioenergy Sustainability Project will fund eight graduate fellowships per year for five years, which is designed to provide classroom support for local teachers while making college students better science communicators. The fellows collaborate with K-12 teachers to design and help supervise student "inquiry activities" exploring ecologically sustainable energy production. A goal of this project is to help future scientists become better at communicating their science, to be able to explain their research results in a popular way to different audiences instead of those absurd terminologies. And a happy byproduct of the NSF grant is that it also benefits local students and teachers, since nationally they are struggling to make K-12 science education more effective.

The objective of this funding is to improve the conversion of nonfood biomass to liquid transportation hydrocarbon fuels via pyrolysis, a process that decomposes biomass using heat in the absence of oxygen to produce a bio-oil that can be upgraded to renewable diesel, gasoline, or jet fuel. This funding opportunity is part of the department’s effort to accelerate development and deployment of sustainable, renewable biofuels that significantly reduce U.S. dependence on foreign oil and lower greenhouse gas emissions.

In Washington, Growth Enegy hailed a study conclusing that ethanol requires 30 percent less energy in production than a decade ago.
“The amount of energy needed to produce a gallon of ethanol has decreased by an average of 30 percent within the past decade, according to a new study by researchers at the University of Illinois at Chicago’s Energy Resources Center. Researchers surveyed the nation’s 150 “dry mill” ethanol plants which produce approximately 85 percent of the nation’s ethanol for energy use and received 90 responses accounting for 66 percent of annual U.S. ethanol production. Survey data found that plants use 28 percent less thermal energy — mostly natural gas, but some coal, biomass and landfill gas — and 32 percent less electricity to turn corn into ethanol. The savings are largely due to the use of more efficient equipment at new plants and energy efficiency retrofits at older facilities.”

Genetic discoveries from a shrub called the burning bush, known for its brilliant red fall foliage, could fire new advances in biofuels and low-calorie food oils, according to Michigan State University scientists.
New low-cost DNA sequencing technology applied to seeds of the species Euonymus alatus – a common ornamental planting – was crucial to identifying the gene responsible for its manufacture of a novel, high-quality oil. But despite its name, the burning bush is not a suitable oil crop.
Yet inserted into the mustard weed – well-known to researchers as Arabidopsis and a cousin to commercial oilseed canola – the burning bush gene encodes an enzyme that produces a substantial yield of unusual compounds called acetyl glycerides, or acTAGs. Related vegetable oils are the basis of the world’s oilseed industry for the food and biofuels markets, but the oil produced by the burning bush enzyme claims unique and valuable characteristics.

26 May 2010 - Bioenergy doesn't have to consume resources--on the contrary, it can save important environmental assets. Brazilian researcher Laércio Couto and his team have proved just that, and for this work he is the first recipient of the World Bioenergy Award.
The World Bioenergy Award was awarded for the first time at the inauguration of the World Bioenergy international conference and trade fair on 25 May in Jönköping, Sweden. Competition was stiff, with 90 nominees from around the world. Seven finalists had been selected from among the nominees. The jury chose Laércio Couto as the winner because thanks to his practically focused research he has proven that it is possible to combine consideration for the environment with energy production.
The basis of his work is the eucalyptus, a species of tree that was introduced to Brazil in 1904. Eucalyptus grows very quickly and soon became a raw material for the forest industry. Laércio Couto became interested in eucalyptus when he was a student, and realised it also has potential for energy production.
