Within the next 10 years, cellulosic ethanol will be an increasingly important source of fuel, given DOE’s commitment to bringing cellulosic ethanol online by 2012 and to increasing its production substantially by 2030.
Clearly challenges lie ahead in determining on what type of land switchgrass and other biomass will be grown, switchgrass would provide the most environmental benefits by displacing these acres of corn, using retired agricultural land, such as CRP, is more likely to be considered in light of corn ethanol policy.
The Department of Energy (DOE) has set the goal of making cellulosic ethanol cost-competitive by 2012, and by 2030, it aims to make biofuels displace 30% of the country’s projected gasoline use (USDOE, 2007).
Some of the primary types of feedstock being considered to meet these goals are crop residues, perennial woody crops, and perennial grasses. Perennial grasses have been a particular focus, with switchgrass receiving the most attention.
