DOE to issue funding opportunity for bioenergy technologies; outliers to current multi-year program plan

February 13, 2014

The US Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) intends to issue, on behalf of the Bioenergy Technologies Office (BETO), a Funding Opportunity Announcement (DE-FOA-0000974) entitled “Bioenergy Technologies Incubator”.

BETO’s mission is to engage in R&D and demonstration at increasing scale activities to transform renewable biomass resources into commercially viable, high-performance biofuels, and bioproducts and biopower that enable biofuel production. To accomplish this mission, BETO develops a multi-year program plan (MYPP) to identify the technical challenges and barriers that need to be overcome. These technical challenges and barriers form the basis for BETO to issue funding opportunities announcements (FOAs) for financial assistance awards in these specific areas.

A team of Virginia Tech researchers, led by Dr. Y.H. Percival Zhang, has developed a process to convert xylose—the second-most abundant sugar in plants—into hydrogen with approaching 100% of the theoretical yield. The findings of their study, published in the journal Angewandte Chemie, International Edition, suggest that cell-free biosystems could produce hydrogen from biomass xylose at low cost.

In the process, hydrogen is produced from xylose and water in one reactor containing 13 enzymes, including a novel polyphosphate xylulokinase (XK). The method can be performed using any source of biomass.
