Abstract The 2011 US Billion‐Ton Update 1 estimates that there are enough agricultural and forest resources to sustainably provide biomass displace approximately 30% of the country's current petroleum consumption. A portion these inaccessible at cost targets with conventional feedstock supply systems because their remoteness or low yields. Reliable analyses projections biofuels production depend on assumptions about system biorefinery capacity, which, in turn, economics, logistics,...
Abstract The 2011 US Billion‐Ton Update estimates that by 2030 there will be enough agricultural and forest resources to sustainably provide at least one billion dry tons of biomass annually, displace approximately 30% the country's current petroleum consumption. A portion these are inaccessible cost targets with conventional feedstock supply systems because their remoteness or low yields. Reliable analyses projections biofuels production depend on assumptions about system biorefinery...
As U.S. energy policy turns to bioenergy, and second-generation biofuels in particular, foster security environmental benefits, consideration should be given the implications of climate risk for incipient bioenergy industry. a case-in-point, we review evidence from 2012 drought, underscoring extreme weather events agricultural sector general, supply chain including reductions feedstock production higher prices commodities biofuels. We also use management framework developed by...
Abstract The use of corn for ethanol production in the United States quintupled between 2001 and 2009, generating concerns that this could lead to conversion forests grasslands around globe, known as indirect land‐use change (iLUC). Estimates iLUC related ‘food versus fuel’ rest on assumption used would come primarily from displacing exports land previously other crops. A number modeling efforts based these assumptions have projected significant increases production. current study tests...
Biofuels are expected to be a major contributor renewable energy in the coming decades under Renewable Fuel Standard (RFS). These fuels have many attractive properties including promotion of independence, rural development, and reduction national carbon emissions. However, several unresolved environmental economic concerns remain. Environmentally, much biomass is come from agricultural expansion and/or intensification, which may greatly affect net impact, economically, lack developed...
Abstract Several crops have recently been identified as potential dedicated bioenergy feedstocks for the production of power, fuels, and bioproducts. Despite being early 1980s, no systematic work has undertaken to characterize spatial distribution their long‐term potentials in United states. Such information is a starting point planners economic modelers, there need this be developed consistent manner variety crops, so that can intercompared support crop selection decisions. As part Sun...
Abstract A socioeconomic model is used to estimate the land‐use implications on U.S. Conservation Reserve Program from potential increases in second‐generation biofuel production. baseline scenario with no production compared a where Renewable Fuels Standard ( RFS 2) volumes are met by 2022. We allow for possibility of converting expiring CRP lands alternative uses such as conventional crops, dedicated or harvesting existing grasses biomass. Results indicate that 2 2‐v) can be primarily crop...
Abstract We evaluate the potential economic availability of willow ( Salix spp.) short‐rotation woody crops in Northeast USA. Based on results from a 20‐year agronomic simulation, USA could potentially provide between 2.1 and 9.7 million dry Mg year −1 , depending farmgate price competition with other energy crops. In diversified biomass energy‐crop scenario, outperforms lignocellulosic planted area production at 91% supply 83% low‐price scenario high‐price also competing 47% 51% area....
Background: This study evaluates the global economic effects of current US RFS2, and potential contribution from advanced biofuels. Results & discussion: Our simulation results suggest that these mandates lead to an increase 0.21% in gross domestic product 2022, including 0.8% USA 0.02% rest world, relative our baseline no-RFS scenario. The incremental contributions biofuels 2022 are estimated at 0.41 0.04% respectively. Conclusion: Although production costs higher than for conventional...
Eucalyptus is a fast-growing tree native to Australia and could be used supply biomass for bioenergy other purposes along the coastal regions of southeastern United States (USA). At farmgate price $66 dry Mg −1 , potential 27 41.3 million year produced on about 1.75 ha in USA. A proposed suite indicators provides practical consistent way measure sustainability particular situation where might grown as feedstock conversion bioenergy. Applying this indicator culture USA basis evaluation...
Abstract Farmgate prices (i.e. price delivered roadside ready for loading and transport) biomass feedstocks directly influence biofuel prices. Using the latest available data, marginal last ton) farmgate of $51, $63, $67 dry ton −1 ($2011) are projected as necessary to provide 21 billion gallons biofuels from about 250 million tons terrestrial in 2022 under price‐run deterministic, demand‐run stochastic simulations, respectively. Sources uncertainty these feedstock supply projections include...
The Billion-ton Reports series has addressed the technical economic potential of supplying additional biomass from farmland and forests.1-3 Underlying each reports supporting scenarios is a assumptions that drive modeled output. have developed over time with support experts industry, academia, government.4 Energy crops not yet reached commodity scale, only exist in commercial production limited number regions, so many key are supported by demonstrations across multiple regions.

Abstract. The U.S. Department of Energy (DOE) has estimated herbaceous biomass availability through simulations with the Policy Analysis System (POLYSYS) agricultural modeling framework. An operational assumption for POLYSYS limited conversion pastureland to perennial grass crops counties east 100th meridian as a proxy precipitation sufficient economically viable yield, but allowed cropland regardless location. Knowledge local conditions raised questions about predicted quantities Texas in...
