Great River Energy proposes to build a wheat straw biorefinery next to a 99mw combined heat power facility (Sandra will probably describe the project). GRE asked NDSU to conduct feasibility study of collecting wheat stovers.
They pay farmer 10-15 for straw and then 35 to bale and haul, 8x13x100 = 40,000 need million

“Economics of Biofuel Feedstock” Dr. Cole Gustafson April 10, 2012
Corn vs. Biofuel Feedstocks• Economics of Corn Production – Market price – Low cost of production• Feedstock Economics – Contract/Price – Sustainable – Lower GHG – Low Cost – Scaleable
North Dakota Projects• Wheat straw to biofuel• Energy beets• Flair gas to fertilizer• USDA feedstock market standards• Economics of corn stalk harvesting
Energy Beet Plant Design• 20 mgy• Feedstock, 20 miles, 30,000 acres• 70% thermal energy from feedstock• Capital investment $40 million w/ working capital
Energy Beet Industry• Phase I Development – 2009 APUC, $58,245, Initial Feasibility – 2009 REC, $330,000, Burn Test, Yield Trials, Juice Storage, Grower Education,• Phase II – 2011 APUC, $73,317, EPA Advanced Biofuel – 2011 REC, $1,000,000, Frontend Processing, Yield Trials, Juice Storage, Promotion• Phase III – Commercialization
Logistics and Transportation• Wheat straw biorefinery• Is collection economically feasible?
Potential Wheat Straw Supply• 1.16 million tons (bone dry)• 10% moisture• Plant height 34.6”• Combine height 7.6”• Producers are willing to supply• Adequate time to harvest
