The Challenge of Replacing Fossil Feedstocks

3 barrels of oil produces the energy equivalent of one human worklife.*

What can replace Fossil Feedstocks? Major Biomass Feedstocks Feedstock Oils Starch Sugar Lignocellulose

Key Chemical Component(s) Plant oils: triglycerides Sugar polymers (polysaccharides) Sucrose, glucose, fructose Lignin, cellulose, hemicellulose

Crop Examples Soybeans, Canola, Sunflowers, Algae Corn, Barley, Grain sorghum Sweet sorghum, sugar beets, sugar cane Wood, crop residues, switchgrass

Some Parting Thoughts • Fossil feedstocks have a huge advantage for liquid fuel & chemicals production • Ultimately fossil feedstocks are finite & cause other problems • Development of alternative sustainable feedstocks takes time and money (think decades and Trillions) • First generation technologies are always flawed • New technologies and products must ultimately be tested and improved in the marketplace, not the laboratory
