Growing South Dakota: Biorenewable Energy

Biomass Resources Ag residues –Corn stover (4-4.5 tons/acre/year) –Grain straw Energy crops –Grasses (10-20 tons/acre/year) –Woody crops Forestry residues –Thinning & mill residue Refuse fuels –Municipal & industrial

South Dakota Bioenergy Field

2010 Center for Bioprocessing Research and Development (CBRD) Collaboration among; – South Dakota School of Mines and Technology (lead institution) –South Dakota State University South Dakota Agricultural Experiment Station –US Department of Energy National Renewable Energy Laboratory –Industry Partners KL Process Design (Rapid City, VeraSun (Brookings), ICM Inc. (Kansas), ZYMETIS (Maryland)

CBRD Research Focus Biomass pretreatment Microbial conversion Separations Process simulation Life cycle analysis

CBRD Accomplishments Started on July 2006 ($ released January 2007) –Interactions with industry & national laboratory –Establishment of industrial advisory council –Submitting infrastructure grants to DOE –Submitting research grants to DOE, industry, USDA, & SD commodity groups –Research project initiated DUSEL project on “mining extremophiles” for enzymes Pretreatment projects on extrusion based clean fractionation and near critical water hydrolysis Conversion project on high solid bioreactors

1.Enhance America's national energy security 2.Promote diversification and environmental sustainability of America's agriculture. 3.Promote opportunities for biobased economic diversification in America's rural communities. 4.Enhance collaboration between land grant universities and federal agencies (USDA, DOE, DOT) National Initiative led by SDSU

Feedstock Development (fuel for the industry) –grain stover –native grasses (switchgrass & prairie cord grass) Biomass Pretreatment & Conversion –Fermentation –Enzymatic process Sun Grant Initiative at SDSU

Joint research –Colleges of Ag/Bio Sciences and Engineering –Regional academic partners –South Dakota private partners System wide research –field-fuel tank-feedlot-families –Multi-source systems (methane digester, wind, bio-oil,& ethanol) Workforce development –Bioprocessing minor –K-12 educational material Integrated Biorenewable energy program at SDSU

How much ethanol can SD produce from corn stover? (2004 data) 4.15 million acres 130 bu/a million bu corn = 15.1 million tons corn & 15.1 million tons stover (1:1 mass ratio) 45% stover removal (sustains tilth) = 6.8 million tons 680 million gallons ethanol/year produced (100 gal ethanol/ton stover) Plus {1.51 billion gallons ethanol from grain} (2.8 gal/bu grain)

Corn Stover Bales for South Dakota’s Biorenewable energy

Developing a stable & sustainable feedstock supply –2010 Drought Center Feedstock infrastructure Conversion efficiency hurdles Cost-competitiveness Challenges to Biomass Energy* * Addressed through public-private research and education partnerships

1.Effective & timely permitting processes 2.Infrastructure investment roads, rails, water, capital 3.Intergenerational farm transfer 4.Economic competitiveness 5.Workforce development education system, quality of life, vitality of communities Public Policy Issues facing Biorenewable Energy Industry

Adapting technology to grow South Dakota

Stewardship of South Dakota’s natural resources while growing the economy

South Dakota’s future is all about people
