Goals / Objectives
The objectives of the Biobased Energy Research and Information Exchange Committee are: a.) to exchange information, strengthen partnerships and facilitate the coordination of research and educational efforts relating to renewable and bio-based energy and b) to strengthen partnerships between research and extension professionals, industry partners, end users, government agencies, policy makers and other effected parties. The committee will be open to individuals in any region. The committee will have a multidisciplinary focus encompassing extension and research professions in fields of agronomy and plant science, agricultural and biosystems engineering, agricultural economics and agribusiness, animal and poultry science, environmental science, family and consumer science and other related disciplines to examine the social, scientific, technical and economic issues associated with using biological sources for energy.
Project Methods
1) Create a clearinghouse of bio-based energy information and resources on topics including but not limited to production, harvesting, transportation and storage of bio-based energy feedstocks, conversion technology, infrastructure development and industry evolution and risk factors, end use application, co-product utilization, energy efficiency, environmental and economic impacts, global impacts and other related issues. 2) Coordinate bio-based energy research efforts, pilot and demonstrational projects and regional conferences. This coordinated effort will address a number of topics including biofuel feed stock production, harvesting, storage and transformation, technical efficiency, economic feasibility and economies of scale of bio-based energy production processes, end product and co-product distribution system and infrastructure constraints, regional comparative advantages in bio-based energy production and projections for the long-term structure of the bio-based energy industry, business models for bio-based energy enterprises, projected shift in cropland use, and other related topics. Because the ultimate success of a biobased energy system will depend on its profitability relative to the current carbon based systems, economic feasibility will remain an important focus. 3) Strengthen partnerships between research and extension professionals, industry partners, end users, government agencies, policy makers and other effected parties. 4) Coordinate information on economic incentives and constraints to the development of bio-based energy industries including capital market considerations and intellectual property rights issues. 5) Disseminate existing informational resources to extension professionals to enhance their response capability to issues associated with using biological sources of energy and coordinate the development of additional bio-based energy related extension and educational material. 6) Provide a forum to identify and discuss important issues relating to bioenergy.

Outputs
Target Audience: One of the objectives of the Biobased Energy Research and Information Exchange Committee is to strengthen partnerships between research and extension professionals, industry partners, end users, government agencies, policymakers, and other effected parties. Each of these categories of individuals represents a link in the chain of research, development, and dissemination of the production, information, and policy for biobased energy. Members of the committee have worked to develop and strengthen targeted partnerships through workshops, publications, presentations, and other communications. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? The bootcamps listed above also provided training and professional development opportunities. One of the specific goals of the bootcamps was to provide graduate students working on biofuel projects an open forum to present their work and receive feedback from a number of colleagues from across the nation. How have the results been disseminated to communities of interest? The results of the project have been disseminated to communities of interest in a variety of ways. For the academic community, the members of the team have written journal articles appearing in AgBioForum, Energy Policy, Agronomy Journal, Energy, American Journal of Agricultural Economics, Green, and Biomass and Bioenergy. Written pieces for lay audiences have appeared as working papers, staff reports, and/or policy briefs from the Center for Agricultural and Rural Development. The members of the projects have also been available to reporters for popular press pieces. Dr. Hart led our extension efforts and provided a number of extension presentations on biofuel research around the country. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? The objectives of the Committee have been accomplished via a variety of approaches. Information exchanges and partnership development was the major focus of the "bootcamp" workshops led by Dr. Bushnell during his time on the project. Several paper and grant ideas were started from those workshops. Partnership ties outside of academia were established and/or strengthened during the Advanced Biofuels workshop, led by Dr. Babcock. These efforts continue to pay dividends as follow-up work continues from several of the partnerships established during this project. Dr. Hart led extension efforts on biofuel markets and impacts, development of alternative feedstocks, and biofuel policy. Dr. Babcock continues to serve as one of thirty experts across academia, industry, and governmental institutions to participate in a workgroup to guide the California Air Resources Board, an institution within the California Environmental Protection Agency, as they develop policies for California's Low Carbon Fuel Standard. Dr. Babcock's former center, the Center for Agricultural and Rural Development, continues to work with UNICA, the Brazilian sugarcane industry association, to explore various governmental policies for the U.S. ethanol industry. This research is being used to shape policy debates within the U.S. and Brazil as both countries look to expand biofuel production and trade. Following the conclusion of the Biobased Industry Center's bioenergy bootcamps over the past couple of years, several academic teams, with individuals at various universities, have been assembled to pursue bioenergy and climate change research and outreach grants from USDA and NSF. Some of those collaborations were incorporated into successful grant applications for sustainable bioenergy. Drs. Raman and Hart are part of the CenUSA team, exploring perennial grass development and potential as a bioenergy source. Dr. Babcock serves as the energy policy platform leader for the Iowa NSF EPSCoR program. Dr. Miranowski has served on the National Academies' Biofuels committee for the past several years. The committee has hosted a number of meetings on biofuel issues.
