Bruce Miller Agricultural Systems Technology and Education Confessions of an Agriculturist: a biofuel opportunity

What’s your Agricultural Paradigm? Human Food Feed for Livestock Fiber for Clothing Energy Production Sun = 4 to 6 billion years Green plant photosynthesis Photovoltaic cells Petroleum, Coal, Uranium, Natural Gas = ?

Why Biofuels? Rudolph Diesel used peanut oil when developing compression ignition engines. Henry Ford ran first automobiles off of Ethanol “We must learn to synthesize materials for every human need from the things that grow.” - George Washington Carver Society must still rely on agriculture for food, feed, fiber AND …. recognize fuel responsibility as well.

Sustainable Energy Production Demand for food AND fuel projected to double by approximately Energy and food are both vital to our society! So, it appears to be ‘a perfect opportunity’ not a ‘perfect storm’ for agriculture. Agriculture will continue to play a significant role in America’s Energy economy.

Food vs. Fuel? Commodity prices affect food prices???? A 30% increase in corn price at the farm equates to ~1.1% increase in food prices containing corn. (Center for Agriculture & Rural Development – ISU) Historically ethanol price does not track corn price. (Houston Biofuels Cons.) “High energy prices cause higher food prices,…Based on the historical relationship between crude [oil] prices and corn prices, current prices for corn are lower than one would predict,”. (Consumers Federation of America) Gasoline prices would be higher if biofuels not blended with gasoline cents per gallon (Samuel Bodman Secretary of the Energy Dep’t)

USDA Crop Data Corn Acres 1 (millions) Usage (million bu) Feed Ethanol Harvest Low (Dec $/bu) $6.00$2.60$3.40 Soybeans Acres (millions) Usage (million bu) Crush Harvest Low (Nov $/bu) $13.89$5.40$6.75 Wheat Acres (millions) Usage (million bu) Feed Milling Harvest Low (Sep $/bu) $8.02$4.30$3.30 US avg reg Gas $/gal$3.08$2.23$1.41

Let’s talk Ethanol U.S. capacity will approach 7.5 billion gallons by early The 2005 Renewable Fuels Standard sets the target at 36 billion gallons by Cellulosic ethanol production will yield 5x the energy needed to grow, harvest, transport, and convert. Based on ‘near farm’ ethanol production sites. On-farm storage and processing…

Why Corn-based Think chicken vs egg Infrastructure building for near-farm production using other feedstocks High feed value from corn- based byproducts 96%-180% energy content of wet distillers grains compared to corn Because we can….

Biofuel Feedstocks Primary biofuels on commercial scale in U.S. Ethanol (~3% today and 7% projected in 2010) Starch from corn and other grains Biodiesel (transesterfied) Soybeans and animal fats USDA ‘POWER PLANTS’ at U.S. National Arboretum… Corn, Sorghum, Sunflower, Canola, Algae, Castor Bean, Lesquerella, Sugar Cane, Hybrid Poplar, Alfalfa, Cuphea, African Oil Palm, Barley, Sugar Beet, Soybean, Camelina, Peanut, Mustard, Switch Grass, Miscanthus, Jatropha, Babassou Palm

Where will Biofuels come from… Most of the current federal R&D is focused on the ‘next generation’ of biofuels. High emphasis on lignocellulosic Short-rotation, perennial crops; rapid regrowth after harvest with multiple harvest per planting. From a field to biorefinery… Feedstocks will evolve to the most efficient Consumers need to shift their pardigm of sustainable energy and agricultural production
