A University of Tennessee and Oak Ridge National Laboratory team led by governor’s chair Jeremy Smith, is using supercomputing to figure out ways to ease the path of turning vegetation into biofuel.
A huge barrier in converting plant polymers to biofuel lies in removing other biomass polymers that subvert this chemical process. To overcome this hurdle, large-scale computational simulations are picking apart lignin, one of those inhibiting polymers, and its interactions with cellulose and other plant components. The results point toward ways to optimize biofuel production and are helping researchers understand the complex chemistry of plant cell walls.

Smith is leading the charge. He is the UT governor’s chair for molecular biophysics based in the Department of Biochemistry and Cellular and Molecular Biology. He also is director of the UT-ORNL Center for Molecular Biophysics.
Researchers at the UT-ORNL Center for Molecular Biophysics have long used supercomputers to model and study lignin polymers and their interactions with cellulose. More recently they’ve started to include other biomass polymers with the idea of simulating all the chemical components of plant cell walls. They’re now applying simulations again to the task: a hundred-million processor hours on Titan, ORNL’s Cray XK7 supercomputer.

The U.S. Department of Energy Bioenergy Technologies Office (BETO) announced up to $23 million in funding to support research and development (R&D) of domestic chemicals and fuels from biomass and waste resources.
The U.S. DOE has announced its intent to issue funding to support high-impact research and development (R&D) projects in two priority areas: sustainable propane and renewable chemicals and algal system cultivation and preprocessing.
Sens. Sherrod Brown, D-Ohio, and Pete Ricketts, R-Neb., in August introduced the Renewable Chemicals Act, a bill that aims to create a tax credit to support the production of biobased chemicals.
The Chemical Catalysis for Bioenergy Consortium, a consortium of the U.S. DOE’s Bioenergy Technologies Office, has launched an effort that aims to gather community input on the development of new biomass processing facilities.
USDA on March 8 celebrated the second annual National Biobased Products Day, a celebration to raise public awareness of biobased products, their benefits and their contributions to the U.S. economy and rural communities.
