Our commitment to sustainability

Our Commitment to Sustainability

DOE’s Biomass Program is committed to developing the resources, technologies, and systems needed for biofuels to grow in a way that enhances the health of our environment and protects our planet. To that end, we are working to…

  • Develop diverse, non-food feedstocks thatrequire little water or fertilizer

  • Foster sustainable forestry practices toenhance forest health

  • Selectively harvest biomass componentswhile leaving adequate soil nutrients

  • Assess life-cycle impacts of major scale-up in biofuels production, from feedstocksto vehicles, addressing:

    • land use and soil health

    • water use

    • air quality issues

    • impacts on greenhouse gas (GHG) emissions

  • Solutions

  • R&D to improve effectiveness and reduce costs of enzymatic conversion

  • R&D on advanced micro-organismsfor fermentation of sugars

  • R&D to improve syngas clean-up and catalyst for alcohol/fuel synthesis

  • Fund loan guarantees, commercial biorefinery demonstrations, and 10% scale validation projects

  • Fundamental feedstock research, enhanced feedstock demonstrations at scale, collection & storage equipment research, development and testing

Future efforts address obstacles to biochemical and thermochemical routes to biofuels, support demonstrations, and resolve infrastructure issues.

Overcoming Barriers to Commercial 2d Generation BIofuels

  • Barriers

  • Enzymatic conversion costs

  • C5 sugars conversion

  • Low Syngas-to-Fuel Yields

  • Commercial-scale integration of process components

  • Inadequate feedstock and distribution infrastructure


Genetic strategies to boost crop yields

Genetic Strategies to Boost Crop Yields

  • Increase feedstock per unit of land by increasing growth rate and photosynthetic efficiency.

  • Increase fuel yield per ton of feedstock through better composition and structure.

  • Enhance disease and pest resistance.

  • Allow germination and growth in cold weather.

  • Use perennial, multi-year crops with efficient nutrient use and reduced fuel input.

  • Permit dense planting and easy harvesting.

  • Deep roots for increased carbon sequestration, drought tolerance and nutrient uptake.

DOE Leverages Partnerships to Achieve Cost Reduction Goals

  • Commercial-Scale Biorefineries (up to $385 million)

    • Six cost-shared, integrated biorefinery demonstration projects to produce130 million gallons of cellulosic ethanol in 5 years using variety of conversion technologies and cellulosic feedstocks

  • 10%-Scale Biorefinery Validation (currently 4 projects up to $114 million)

    • Cost-shared, integrated biorefinery demonstrations using cellulosic feedstocks to produce renewable fuels; one-tenth of commercial scale

    • Four selectees announced last month for total investment of $114 million; more selectees expected by April 2008

  • Ethanologen Solicitation (up to $23 million)

    • Five selected research teams working on microorganisms

  • Enzyme Solicitation (up to $33.8 million)

    • Creating highly effective, inexpensive enzyme systems forcommercial biomass hydrolysis; second phase: cellulase development with cost-sharing industry partners

  • Thermochemical Conversion (up to $7.75 million)

    • Integration of gasification and catalyst development

  • Joint DOE-USDA Solicitation ($18 million)

    • Biomass R&D Initiative

Ghg methodologies task force of global bioenergy partnership gbep

GHG Methodologies Task Force of Global Bioenergy Partnership (GBEP)

  • GHG methodologies taskforce established by GBEP steering committee in May 2007.

  • Desired end result is flexible methodology for policy makers in all countries.

  • First taskforce meeting held October 2007.

  • Second meeting scheduled for March 6-7 2008 and will include solid biomass and liquid biofuels.


Ghg taskforce work plan

GHG Taskforce Work Plan

1. Review existing methodologies;

2. Develop a harmonised approach so GHG lifecycle assessments can be compared on an equivalent basis;

3Encompass the full well-to-wheel lifecycle of transport biofuels;

4Not indicate a preference for any particular existing methodology or feedstock, or to limit parameters; and

5Define parameters and inputs to be considered when conducting a LCA and develop a good practice document.

Results of first gbep ghg meeting

Results of First GBEP GHG Meeting

  • Accomplished review of existing efforts in defining methodologies

  • Reached broad agreement that it is possible to develop common methodology

  • Developed preliminary list of parameters needed for a common methodology in a “checklist”

  • Recognized issues needing further discussion


Development of common checklist

Development of Common Checklist

  • The GHGs to be covered;

  • The effects of direct land use change, both in terms of above and below ground carbon inventories;

  • The effects of the production cycle, including fertilizer production, agricultural inputs and processing energy;

  • Combustion of the finished biofuel and tailpipe emissions; and

  • Corresponding factors to facilitate comparison with the fuel replaced.


Issues needing further discussion

Issues Needing further Discussion

  • Accounting for co-product emissions;

  • Ensuring transparency in default values and parameters used, and assumptions made, in conducting a GHG lifecycle assessment;

  • Whether and how to take account of the effects of indirect land use change;

  • How to take account of future technologies (e.g. cellulosic) in the design of the methodology.
