The U.S. Department of Energy has announced funding for new research centers to accelerate the development of specialty plants and processes for a new generation of biofuels and bioproducts.

The Center for Bioenergy Innovation (CBI), led by Oak Ridge National Laboratory, is one of four bioenergy centers chosen by DOE to advance a new biobased economy with the production of fuels and other products directly from nonfood biomass. The DOE announcement provides a total of $40 million in initial funding for the four centers in fiscal year 2018, with plans for a total five years of funding, a press release said.

The new centers follow the success of predecessor Bioenergy Research Centers established by DOE’s Office of Biological and Environmental Research within DOE’s Office of Science in 2007. The ORNL-led BioEnergy Science Center (BESC), for instance, has demonstrated scientific breakthroughs in its mission to overcome the natural resistance of plants to being broken down and converted into useful bioproducts.

“Our team of leading researchers is excited to use new approaches in biology to address the basic research challenges in developing real-world applications in the future sustainable bioeconomy,” said CBI Chief Executive Officer Gerald Tuskan. Tuskan, an ORNL Corporate Fellow, led the sequencing of the genome of Populus—a fast-growing perennial tree recognized for its potential in biofuels production—as well as the largest study of natural diversity in poplar trees for BESC.

Mohammad A. “Moe” Khaleel has been named associate laboratory director for energy and environmental sciences at the U.S. Department of Energy’s Oak Ridge National Laboratory.

The work that Khaleel will oversee for the Energy and Environmental Sciences Directorate, or EESD, includes biological and environmental research for DOE’s Office of Science and an extensive set of research and development programs supported by DOE’s Office of Energy Efficiency and Renewable Energy, Office of Electricity Delivery, and Energy Reliability and Office of Fossil Energy.

EESD also engages with a broad external community that includes a growing list of industrial partners through the ORNL-managed BioEnergy Science Center, the Manufacturing Demonstration Facility, and the National Transportation Research Center, a press release said.

“Moe brings a rich background as both a researcher and scientific leader,” ORNL Director Thom Mason said. “In his new position, he will oversee activities that translate basic science into applied research and development (R&D), with direct benefits for energy production, transmission, and conservation. ORNL will benefit from his experience and his vision.” [Read more…]

Biofuels pioneer Mascoma LLC and the U.S. Department of Energy’s BioEnergy Science Center have developed a revolutionary strain of yeast that could help significantly accelerate the development of biofuels from nonfood plant matter.

BESC is led by Oak Ridge National Laboratory.

The approach could provide a pathway to eventual expansion of biofuels production beyond the current output limited to ethanol derived from corn.

C5 FUEL, engineered by researchers at Mascoma and BESC, features fermentation and ethanol yields that set a new standard for conversion of biomass sugars from pretreated corn stover—the non-edible portion of corn crops such as the stalk—converting up to 97 percent of the plant sugars into fuel.

The associate laboratory director for Energy and Environmental Sciences at Oak Ridge National Laboratory and two University of Tennessee-ORNL Governor’s Chair researchers are among the newly elected fellows of the American Association for the Advancement of Science.

EES Associate Laboratory Director Martin Keller and Governor’s Chairs Sudarsanam Suresh Babu and Terry Clyde Hazen will receive the highest honor bestowed by members of the AAAS on their peers. AAAS is the world’s largest general scientific society and publisher of the journal Science.

Keller came to ORNL in 2006 from Diversa Corporation, where he held a series of research management positions. He was cited by his AAAS peers for “distinguished contributions to bioenergy science, and for dynamic and inspiring leadership of innovative partnerships to advance the development and deployment of clean energy technologies.” [Read more…]

Researchers seeking to improve production of ethanol from woody crops have a new resource in the form of an extensive molecular map of poplar tree proteins, published by a team from the U.S. Department of Energy’s Oak Ridge National Laboratory.

Populus, a fast-growing perennial tree, holds potential as a bioenergy crop due to its ability to produce large amounts of biomass on non-agricultural land. Now, a study by ORNL scientists with DOE’s BioEnergy Science Center has provided the most comprehensive look to date at poplar’s proteome, the suite of proteins produced by a plant’s cells. The study is featured on the cover of January’s Molecular and Cellular Proteomics.

The identification of key proteins in a group of heat-loving bacteria by researchers at the Department of Energy’s BioEnergy Science Center could help light a fire under next-generation biofuel production.

Scientists have long been on the hunt for cost-effective ways to break down complex plant material such as switchgrass in order to access sugars that are fermented to make biofuels. Conventional processes involve the addition of commercially produced enzymes to break down the cellulose.
