Incorporating Bioenergy into Sustainable Landscape Designs Workshop

The Bioenergy Technologies Office hosted two workshops on Incorporating Bioenergy into Sustainable Landscape Designs with Oak Ridge and Argonne National Laboratories. The first workshop focused on forestry landscapes and was held in New Bern, NC, from March 4-6, 2014. The second workshop focused on agricultural landscapes and was held in Argonne, IL, from June 24-26, 2014. Landscape design offers a promising means for sustainably increasing bioenergy production while maintaining or enhancing other ecosystem services.

Price Projections of Feedstocks for Biofuels and Biopower in the U.S.

a b s t r a c t
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 Mg1 ($53.00 dry ton1) is needed to procure this supply, while a demand-run simulation

2013 Feedstock Supply and Price Projections and Sensitivity Analysis

Abstract: Farmgate prices (i.e. price delivered roadside ready for loading and transport) for biomass
feedstocks directly infl uence biofuel prices. Using the latest available data, marginal (i.e. price for the
last ton) farmgate prices of $51, $63, and $67 dry ton–1 ($2011) are projected as necessary to provide
21 billion gallons of biofuels from about 250 million dry tons of terrestrial feedstocks in 2022 under
price-run deterministic, demand-run deterministic, and stochastic simulations, respectively. Sources

Climate Risk Management for the U.S. Cellulosic Biofuels Supply Chain

a b s t r a c t
As U.S. energy policy turns to bioenergy, and second-generation biofuels in particular, to
foster energy security and environmental benefits, consideration should be given to the
implications of climate risk for the incipient bioenergy industry. As a case-in-point, we
review evidence from the 2012 U.S. drought, underscoring the risk of extreme weather
events to the agricultural sector in general, and the bioenergy supply chain in particular,
including reductions in feedstock production and higher prices for agricultural

Microalgae Water Use and Costs

Add To Map

A key advantage of using microalgae for biofuel production is the ability of some algal strains to thrive in waters unsuitable for conventional crop irrigation such as saline groundwater or seawater. Nonetheless, the availability of sustainable water supplies will provide significant challenges for scale-up and development of algal biofuels. We conduct a partial techno-economic assessment based on the availability of freshwater, saline groundwater, and seawater for use in open pond algae cultivation systems.

Agricultural Renewable Solid Fuels Data

All provided information is based on the Proximate Analysis testing for solid fuels in accordance with American Society for Testing and Materials(ASTM).

The compiled information should be used only as a general comparative guide for agricultural renewable fuels.

The evaluated agricultural renewable fuel groups include grains, crop residues, fibers, and agricultural processing co-products.

Agricultural products naturally contain variability which is dependent on geographical regions, grain/plant varieties, and seasonal changes.

Progress Toward Evaluating The Sustainability Of Switchgrass As A Bioenergy Crop Using The SWAT Model

Adding bioenergy to the U.S. energy portfolio requires long‐term profitability for bioenergy producers and
long‐term protection of affected ecosystems. In this study, we present steps along the path toward evaluating both sides of
the sustainability equation (production and environmental) for switchgrass (Panicum virgatum) using the Soil and Water
Assessment Tool (SWAT). We modeled production of switchgrass and river flow using SWAT for current landscapes at a
regional scale. To quantify feedstock production, we compared lowland switchgrass yields simulated by SWAT with estimates

Land-Use Change and Bioenergy: Report from the 2009 workshop

The U.S. Department of Energy Biomass Program sponsored the Land-Use Change and Bioenergy workshop in Vonore, Tennessee, from May 11 to May 14, 2009. More than 50 experts from around the world gathered to review the state of the science, identify opportunities for collaboration, and prioritize next steps for the research and data needed to address key issues regarding the land-use effects of bioenergy policies. A key outcome of the workshop was the
identification of research areas that may improve our understanding of land-use change in a bioenergy context.

The land use–climate change–energy nexus

Landscape ecology focuses on the spatial patterns and processes of ecological and human interactions. These patterns and processes are being altered by both changing resource-management practices of humans and changing climate conditions associated, in part, with increases in atmospheric concentrations of greenhouse gases. Dominant resource-extraction and land-management activitiesinvolve energy, and the use of fossil energy is one of the key drivers behind increasing greenhouse gas emissions as well as land-use changes.

Use of SWAT model to evaluate the sustainability of switchgrass production at a national scale

As the US begins to integrate biomass crops and residues into its mix of energy feedstocks, tools are needed to measure the long-term sustainability of these feedstocks. Two aspects of sustainability are long-term potential for profitably producing energy and protection of ecosystems influenced by energy-related activities. The Soil and Water Assessment Tool (SWAT) is an important model used in our efforts to quantify both aspects. To quantify potential feedstock production, we used SWAT to estimate switchgrass yields at a national scale.
