U.S. bioenergy crop production cost, supply curve, and transportation
cost studies are summarized and compared. Production cost estimates ra
nge from <$22/dry Mg [$20/dry ton (dt)] to more than $110/dry Mg ($100
/dry ton) depending on crop, region, yield and method of analysis. A d
etailed description of an ORNL study is presented as a representative
production cost study. Three national supply curve estimates are compa
red; for a quantity of 110 million dry Mg (100 million dry tons), thes
e studies estimate marginal bioenergy crop prices of $29/dry Mg ($26/d
t) (farmgate), $46/dry Mg ($42/dt) (farmgate), and $55/dry Mg ($50/dt)
(delivered). Three regional supply curve analyses are also discussed.
Bioenergy crop transportation costs estimates range from $5.5/Mg ($5/
dt) and $8/Mg ($7.27/dt) for a haul distance of 40 km (25 miles). The
paper closes with a discussion of analytical needs. (C) 1998 Elsevier
