Biomass feedstock nitrogen study compares four grasses; switchgrass is most efficient. A USDOE and USDA study concluded that 50 million U.S. acres of cropland, idle cropland, and cropland pasture could be converted from current uses to the production of perennial grasses, such as switchgrass, from which biomass could be harvested for use as a biofuel feedstock. Economically viable production of a perennial grass monoculture from which substantial quantities of biomass are removed annually is...

THOUSAND OAKS, Calif., Nov. 10 /PRNewswire/ -- Energy crop company Ceres, Inc. announced today that it plans to expand an advanced trait development project to increase biomass yields of several energy grasses by as much as 40% in coming years, while simultaneously decreasing the use of inputs such as nitrogen fertilizers. The project, which was selected by the U.S. Department of Energy (DOE) from among 3,700 renewable energy proposals, will be funded in part by a $5 million advanced...

Using prairie plants to produce bio-energy would help bird populations threatened by the conversion of grasslands to corn, scientists in Michigan said. There are ways to grow biofuel that are more benign, David Flaspohler, an environmental scientist at Michigan Tech, said in the journal BioScience. The demand for ethanol from corn is converting land on a scale not seen since virgin prairies were plowed and huge swaths of the nation's forests were first cut to grow food crops, Flaspohler said...

Scientists in Pennsylvania report that boosting production of crops used to make biofuels could make a difficult task to shrink a vast, oxygen-depleted "dead zone" in the Gulf of Mexico more difficult. The zone, which reached the size of Massachusetts in 2008, forms in summer and threatens marine life and jobs in the region. Their study is scheduled for the Oct. 1 issue of ACS' semi-monthly journal Environmental Science & Technology. Christine Costello and W. Michael Griffin and...

They've been dubbed "grassoline" - second generation biofuels made from inedible plant material, including fast-growing weeds, agricultural waste, sawdust, etc. - and numerous scientific studies have shown them to be prime candidates for replacing gasoline to meet our transportation needs. However, before we can begin to roll down the highways on sustainable, carbon-neutral grassoline, numerous barriers must be overcome, starting with finding ways to break lignocellulosic biomass down into...

Scientists say they are forging ahead in developing replacements for petrochemical fuels that will be cost-competitive and renewable while having a minimal impact on the environment, reports Genetic Engineering & Biotechnology News (GEN). A consensus is emerging that no one technology will reign supreme and that a range of current and novel methodologies will contribute to meeting biofuel needs, according to the June 15 issue of GEN...

Rice University scientists warned that the United States must be careful that the new emphasis on developing biofuels as an alternative to imported oil takes into account potential damage to the nation's water resources."The ongoing, rapid growth in biofuels production could have far-reaching environmental and economic repercussions, and it will likely highlight the interdependence and growing tension between energy and water security," said a report titled "The Water Footprint of Biofuels: A...

President Barack Obama said on Wednesday that the corn-based ethanol industry needs to remain viable until new types of biofuels can be commercialized as quickly as possible, Reuters reported. Obama wrote in a letter to a group of farm-state governors that he is committed to moving as quickly as possible to commercialize an array of emerging cellulosic technologies so that tomorrow's biofuels will be produced from sustainable biomass feedstocks and waste materials rather than corn. Ethanol...

THOUSAND OAKS, Calif., May 20 /PRNewswire/ -- Energy crop company Ceres, Inc. announced today that switchgrass can produce substantially more biomass than previously reported and that average yields often used by academics and policymakers to forecast bioenergy economics and environmental benefits may, in fact, be far too conservative. The company reported that yield results from its nation-wide network of field trials showed that average biomass yields among switchgrass seed varieties...
