Today, carbon-rich fossil fuels, primarily oil, coal and natural gas, provide 85% of the energy consumed in the United States. Fossil fuel use increases CO2 emissions, increasing the concentration of greenhouse gases and raising the risk of global warming. The high energy content of liquid hydrocarbon fuels makes them the preferred energy source for all modes of transportation. In the US alone, transportation consumes around 13.8 million barrels of oil per day and generates over 0.5 gigatons of carbon per year. This has spurred intense research into alternative, non-fossil energy sources. The DOE-funded Joint BioEnergy Institute (JBEI) is a partnership between six leading research institutions (Lawrence Berkeley Lab, Sandia Labs, Lawrence Livermore Lab, UC-Berkeley, UC-Davis, and the Carnegie Institute for Science) that is focused on the production of infrastructure compatible biofuels derived from non-food lignocellulosic biomass.  Biomass is a renewable resource that is potentially carbon-neutral. Plant-derived biomass contains cellulose, which is more difficult to convert to sugars.  The development of cost-effective and energy-efficient processes to transform cellulose and hemicellulose in biomass into fuels is hampered by significant roadblocks, including the lack of specifically developed energy crops, the difficulty in separating biomass components, low activity of enzymes used to hydrolyze polysaccharides, and the inhibitory effect of fuels and processing byproducts on the organisms responsible for producing fuels from monomeric sugars. This presentation will highlight the research efforts underway at JBEI to overcome these obstacles, with a particular focus on the development of an ionic liquid pretreatment technology for the efficient production of monomeric sugars from biomass.




Dr. Blake A. Simmons grew up in Blair, Nebraska, a small town north of Omaha. After leaving the Navy in 1994 with an honorable discharge as a Petty Officer, Second Class, he attended the University of Washington and obtained a B.S. in Chemical Engineering in 1997. He then attended graduate school at Tulane University after receiving a Louisiana Board of Regents Fellowship, and then joined Sandia National Laboratories (Livermore, CA) in 2001 as a Senior Member of the Technical Staff, serving as a member of the Materials Chemistry Department. He was promoted to Manager of the Energy Systems Department in 2006. The primary focus of the department was the development of novel materials-based solutions to meet the nation’s growing energy demands. In 2007, he was one of the principal co-investigators of the Joint BioEnergy Institute (JBEI,, a $125M DOE funded project tasked with the development and realization of next-generation biofuels produced from non-food crops.  He is currently serving as the Vice-President of the Deconstruction Division at JBEI, where he leads a team of 41 researchers working on advanced methods of liberating fermentable sugars from lignocellulosic biomass. He also manages the Biomass Science and Conversion Technology Department at Sandia. He has over 123 publications, book chapters, and patents. His work has been featured in the New York Times, the Wall Street Journal, the San Francisco Chronicle, Fast Company, and the KQED televised science program Quest.
