The Department of Energy will disburse $33.8 Million to support commercial production of cellulosic biofuels, specifically viable enzymes - a key step to enabling bio-based production of clean, renewable biofuels such as cellulosic ethanol. As part of the President's Twenty in Ten Plan, DOE is pursuing a long-term strategy to support increased availability and cost-effective use of renewable and alternative fuels. Twenty in Ten seeks to displace 20 percent of U.S. gasoline usage by 2017 through diversification of clean energy sources and increased vehicle efficiency.
With a minimum 50 percent industry cost-share, this funding will total nearly $68 million to further enzyme commercialization efforts. By harnessing the power of enzymes, which are responsible for many of the biochemical processes in nature, biorefineries can more efficiently use cellulosic (non-food) feedstocks for biofuels production. This funding aims to further reduce costs of enzyme system preparations in process-relevant conditions. Since 2000, DOE enzyme development advancements have yielded thirty-fold cost reductions mainly on enzyme production.
This biofuels effort focuses specifically on systems to hydrolyze and saccharify cellulosic biomass feedstocks. Saccharification enables the biorefining process by breaking down pretreated cellulosic material into more simple sugars, allowing them to be further processed through fermentation and ultimately turned into biofuels such as ethanol. Enzymes developed under this program must prove durable and effective in process-relevant conditions.
