  1. Biofuels & Water Resources Mini-Retreat Sponsored by: Department of Biosystems Engineering Nebraska Center for Energy Sciences Research Water Resources Research Initiative Biofuels & Water Resources Mini-Retreat

  2. (September 2006) Existing Capacity: 715 million gallons Created by Maribeth Milner Biofuels & Water Resources Mini-Retreat

  3. (2006 Expanded) 6 plants being expanded, Completion expected in 2007 Capacity: +824 = 1539 million gallons Biofuels & Water Resources Mini-Retreat Created by Maribeth Milner

  4. (Dec. 2007) NEW Completion expected in 2007 Source: Ethanol Producer Magazine, December 2006 Capacity: +815 = 2354 million gallons Created by Maribeth Milner Biofuels & Water Resources Mini-Retreat

  5. Annual NE Ethanol Production Capacity and Corn Use *Conversion rate = 2.8 gallons ethanol per bushel †Percent of total corn production in NE: 1.28 (06), 1.31 (08), 1.36 (10) billion bu Biofuels & Water Resources Mini-Retreat

  6. Mini-Retreat Goals • To share information about faculty research projects and interests related to Biofuels and Water Resources • Identify critical research areas for new projects • Kick-start new initiatives and collaborations amongst UNL faculty, scientists at other institutions, and with the private sector • Interdisciplinary to tackle complex issues • Need for both biophysical and socio-economic sciences Biofuels & Water Resources Mini-Retreat

  7. Over time, water use by existing ethanol plants is becoming more efficient. The current average is about 4 gallons of water per gallon of ethanol produced from corn grain. New plants require about 3 gallons H2O per gallon EtOH. D. Keeney. 2006. Water use by ethanol plants. iatp@iatp.org Biofuels & Water Resources Mini-Retreat

  8. (Dec. 2007) 2007 Ethanol Capacity is 70% of NE 2004-06 Avg Corn Production Potential Grain Consumption: 872 million bushels Biofuels & Water Resources Mini-Retreat Created by Maribeth Milner

  9. Even though the ethanol industry will have the capacity to consume 70% of the state's corn grain by next harvest, this will likely highly depend on economics and how far these plants are pushed, since these numbers represent a maximum production level. Significant corn acreage increases in 2007 will boost production by perhaps ~10%. Biofuels & Water Resources Mini-Retreat

  10. A Nebraska Water-Biofuel Perspective • NE has ≈5 million acres of irrigated corn • Requires about 1.6x1012 gallons of water/year, or roughly 1 million gallons per NE citizen • New ethanol plants use about 3 gallons of water per gallon of ethanol produced • NE currently has about 1 billion gallons of annual ethanol production capacity, which requires 3x109 gallons of water, which is <0.2% of water used to irrigate NE corn Biofuels & Water Resources Mini-Retreat
