U.S. Department of Energy

Sun Grant Initiative Competitive Grants Program

From 2008-2017, the Sun Grant Initiative partnered with the U.S. Department of Energy to manage a competitive grants program. The overall goal of this program was to utilize congressionally directed funds to leverage the North Central Regional Sun Grant’s Competitive Grant program at SDSU to address key issues and research gaps related to development of the bio economy. Specific objectives of this program were to:

  • Identify research projects through a Regional Competitive Grants program that were relevant to the sustainable production, harvest, transport, delivery and processing/conversion of cost-competitive, domestically grown biomass.
  • Build local expertise and capacity at the North Central Regional Sun Grant Center at SDSU through an internal selection of key bioenergy research projects.

Of these funds, 75% were allocated to the Regional Competitive Grants Program and 25% were dedicated to building local expertise and strength at SDSU. Three nationwide and two internal competitions were completed. Priority areas for these competitions included:

  • Biomass feedstock logistics including biomass harvesting, handling, transportation, storage and densification;
  • Sustainable biomass feedstock production systems including biomass crop development, production and life-cycle analysis.
  • Biomass production systems that optimize biomass feedstock yield and economic return across a diverse landscape while minimizing negative effects on the environment and food/feed production.
  • Promotion of knowledge-based economic development in science and technology and to advance commercialization of inventions that meet the mission of the Sun Grant Initiative. A total of 33 projects were selected for funding through this program. Primary research topics as well as funding associated with each subject area are shown in Figure 3.

Department of Energy Regional Feedstock Partnership

The Regional Feedstock Partnership was formed in 2008 by the United States Department of Energy and the Sun Grant Initiative to address issues associated with the development of a sustainable and projectable supply of cellulosic feedstocks.

Department of Energy Research Grant Awardee

Although not inclusive, several key impacts from various projects funded through this award are highlighted below.

  • University of Minnesota researchers are developing a web based decision support tool (CE2T—The Crop Enterprise and Environmental Budgeting Tool) to allow a broad set of users to make informed decisions about the economic and environmental value of perennial based biomass crop production on the landscape (Figure 1).

  • A SDSU project created the opportunity for researchers to discover a way to treat soybean meal and dried distillers grains from corn ethanol plants to make a protein-rich fish feed that can fully replace fishmeal in aquaculture diets (Figure 2). This work led to a patented process and a Brookings-based startup company to commercialize the technology - Prairie AquaTech. Prairie AquaTech has grown to 30 employees since its inception and is currently constructing a 300,000 square foot, $60 million commercial facility with plans to hire 35 additional employees once the plant is operational. Prairie AquaTech has the capability to help solve the global problem of high-quality animal feed ingredients, help secure the world’s food supply, and provide a solution to the U.S.’s problem of the largest natural resource trade deficit by starting more aquaculture farms with a locally available feed ingredient.

  • Researchers at Iowa State University partnered with DuPont, New Holland and AGCO in Sun Grant projects to better understand how feedstock densification and storage can improve conversion of corn stover to biofuels. This research in biomass supply chains has provided guidance for AGCO to set goals for biomass machinery design and allowed their machines to operate at peak efficiency throughout the harvest season (Figure 3).

  • SDSU researchers developed a novel plasma activation system to efficiently create nano structured porous bio-char suitable for super capacitors. The plasma activation technology developed through this project has attractive potential for commercialization because plasma activation was completed with only 50 watts of power in five minutes, thus greatly reducing the cost of super capacitors.
  • Purdue University researchers characterized the opportunities and challenges associated with producing a range of perennial bioenergy crops including miscanthus (Figure 4), switchgrass and mixed prairie grasses, across landscapes which are considered marginal. Specifically, they identified those crops that provide the highest yields as well as the greatest theoretical return to producers, the role of fertilization, costs to the environment (through greenhouse gas emission and nitrate leaching) and establishment and transportation costs.
  • Four invention disclosures;
  • Eight patents;
  • More than 30 jobs created; and
  • Training of undergraduate (110), M.S. (39) and Ph.D. (38) students and post-docs (27).
  • More than 100 peer-reviewed publications;
  • Five book chapters;
  • More than 275 presentations to diverse audiences; and
  • Nearly 40 outreach publications.
