The bioenergysite website recently made a list of the latest in biofuel research and development: (1) Algal photobioreactors made of plastic from permeable, "forward-osmosis" membranes: The reactors (developed by the United States National Aeronautics and Space Agency, NASA) are large plastic bags which can be filled with wastewater, which serves as a culture medium for the growth of algae. The algae grow on the wastewater medium, and the cleaned water seeps through the one-way semi-permeable membrane. The algae can then be harvest for further processing into biofuels and other useful materials; (2) Tobacco as biodiesel feedstock: Scientists at the Biotechnology Foundation Laboratories at Thomas Jefferson University have successfully modified a tobacco plant that produces oil in the leaves; the modified plant had 20% higher oil yield compared to the unmodified plant, (3) Cyanobacteria which converts carbon dioixde and sunlight, directly into biofuel isobutanol. The organism, developed by a team at the University of California, Los Angeles (UCLA), uses a "direct route" for fuel conversion. The organism directly produces the biofuel, instead of being "intermediately" processed for biofuel production. The direct-route can substantially reduce the production cost of the biofuel, (4) A strain of E. coli which directly converts simple sugars into biodiesel, alcohol and waxes (plus the enzyme, hemicellulase): This "L9" strain was developed by researchers at the Joint BioEnergy Institute (JBEI) of the United States Department of Energy (US-DOE), (5) A new and more cost-effective cellulase for cellulose ethanol production: Novozymes (an enzyme company) developed "Cellic CTec2" enzymes, could reportedly enable the biofuel industry "to produce cellulosic ethanol at a price below $2 per gallon for the initial commercial-scale plants that are scheduled to be in operation in 2011"..

The collaborative project by partners in Denmark, Sweden and Norway, which may help promote the use of renewable energy sources and sustainable crop production systems, has been initiated. Called the "Cultivation for bioenergy, water preservation and field protection" (BioM), the project will "develop economically and environmentally sustainable large-scale biomass productions for energy purposes, which do not compete with food production". As listed in the Danish AgroTeck website, the four major activities of the project are: (1) Project management, which ensures an effective leadership and communication platform; (2) Cultivation system and documentation of effects on the environment and nature, which focus on optimal cultivation systems for energy crops in large scale systems and mapping and measuring the effects of these; (3) Development of techniques and harvest and storage methods, which focus on optimization of harvest process, biogas yield, upgrading gas for transport use, and recycling nutrients for organic plant production; (4) Organizing, local approval and business development will ensure the long term sustainability of the cultivation systems by demonstration sites and dissemination of the achieved knowledge. The project, which is co-financed by the EU's Kattegat-Skagerak programme, was launched last January 2010, and will run for three years..

Energy Crops and Feedstocks for Biofuels Production

An interdisciplinary research team from the University of Maryland and the Bowie State University has received a four-year grant of US$3.4 million from the National Science Foundation's Plant Genome Research Project, "to work on ways for turning poplar trees into high-yield crops for biofuels including ethanol". A sustainability dimension has been included in the scenario that the hybrid trees would be grown on plantations and harvested without affecting existing woodlands. According to lead researcher Gary Coleman, there are many advantages of a poplar crop over traditional biofuel sources: "Growing trees doesn't eat into farmland, and trees don't require a lot of maintenance during their growth cycle," said Coleman. "A dedicated energy crop like poplar would contribute to the development of a sustainable and renewable energy system". In order for poplar to become an effective biofuel feedstock, its growth cycle needs to speed up and become more efficient; and one of the keys to doing so is to understand how it stores and cycles nitrogen. The research team is looking into the mechanisms of nitrogen cycling, finding ways to increase the rates of the cellular reactions, and identifying genes that play a crucial role in the process. The final objective is to "breed a variety of poplar with a more efficient nitrogen process, optimized for growth and rapid maturity". Genetic aspects of the study has been recently made possible by the availability of the poplar tree's genome sequence..

Scientists from the Agricultural Research Service of the United States Department of Agriculture "are developing new sustainable technologies to convert varieties of hulled and hull-less winter "energy" barley into fuel ethanol". Their efforts are aimed to make barley a major player in bioenergy production, and could also help farmers in some parts of the United States develop a profitable 2-year rotation of winter barley, corn, and soybeans. Barley acts as a cover crop with two benefits:  helps protect soil/nutrients and  prevents migration of fertilizers from crop fields to the Chesapeake Bay. Since winter barley is grown on seasonally fallow land, producing biofuels from winter barley would not interfere with food production. Scientists from the USDA-ARS Plant Science Research Unit are reportedly "just a few years into making crosses between hull-less barley and barley with resistance to Ug99, a stem rust that can inflict crop losses of up to 100 percent". Once robust lines have been developed containing both traits, the breeding of traits to enhance ethanol production will be done..

A research study funded by the Biotechnology and Biological Sciences Research Council (BBSRC, United Kingdom) could lead to the cultivation of bioenergy crops which could be converted to "eco-friendly biofuels". Dr. Paul Dupree (University of Cambridge, United Kingdom) and his team have found three enzymes responsible for the production of all detectable levels of a type of sugar called glucomannan. Using the model plant, Arabidopsis, Dr. Dupree and his team showed that "the quantity of glucomannan can be increased or decreased in the stem with no visible detrimental effects on plant development or cell wall strength"; however, a detrimental effect on seed development was observed. Although the observed increases in fermentable sugar are encouraging, further work may be necessary "to understand how to make substantial improvements in crop species". Dr Dupree says, "We now know that it may be possible to increase glucomannan specifically in harvestable plant organs, such as stems. This could be very beneficial for the production of bioenergy crops where higher proportions of enzyme-accessible fermentable sugars, such as those in glucomannan, could lead to higher yields of fuel. Achieving higher fuel yields from crops will increase the likelihood of sustainable and economic biofuels displacing fossil fuels". The report of research results are published in The Plant journal (URL above)..

A joint press release at the Australian Government website announced that the country's Renewable Energy Target scheme "will be enhanced to provide greater certainty for households, employees and businesses within the renewable energy industry, as we build the low pollution economy of the future". The revised arrangements will reportedly deliver on the Government's 20 percent by 2020 Renewable Energy Target (RET). Beginning January 2010, the existing scheme will include two parts: (1) the Small-scale Renewable Energy Scheme (SRES) and (2) the Large-scale Renewable Energy Target (LRET). "The LRET, will cover large-scale renewable energy projects like wind farms, commercial solar and geothermal, will deliver the vast majority of the 2020 target. This will free these projects from uncertainties that may have been caused by strong demand for small-scale renewable technologies. The SRES will cover small-scale technologies such as solar panels and solar hot water systems and deliver the remainder of the target. It will provide a fixed price of $40 per megawatt hour of electricity produced, providing direct support for households that take action to reduce emissions". The changes are expected (2) to deliver more renewable energy than the original 20 per cent target, (2) to ensure the building of a clean energy future for Australia, and (3) new jobs and investment in both large and small-scale renewable energy projects.
