The economic availability of biomass resources is a critical component in evaluating the commercial viability of biofuels. To evaluate projected farmgate prices and grower payments needed to procure 295 million dry Mg (325 million dry tons) of biomass in the U.S. by 2022, this research employs POLYSYS, an economic model of the U.S. agriculture sector. A price-run simulation suggests that a farmgate price of $58.42 Mg-1 ($53.00 dry ton(-1)) is needed to procure this supply, while a demand-run simulation suggests that prices of $34.56 and $71.61 Mg-1 ($30.00 and $62.00 dry ton(-1)) in are needed in 2012 and 2022, respectively, to procure the same supply, under baseline yield assumptions. Grower payments are reported as farmgate price minus resource-specific harvest costs. (C) 2011 Elsevier Ltd. All rights reserved.
