The Sun Grant Initiative, through funding from the U.S. Department of Transportation (DOT), administers a competitive research program for land-grant universities and their partners. Each of the five Sun Grant Centers manages its own regional competitive grants program to best meet the challenges of bioenergy and biomass research and education needs within their respective regions. Each Center utilizes approximately 75% of their total funding for competitive grant projects. The remaining funds are used internally to build Center capacity.
Department of Transportation Research Grant Awardees
The U.S. Department of Transportation provided funding for the NCRSGC to administer a competitive research program for land grant universities and their partners in the region. This program concluded at the end of 2017. The NCRSGC Center utilized approximately 75 percent of the DOT funds for regional competitively selected awards while approximately 25 percent of the funds were used internally at SDSU to build research capacity.
Working with the Sun Grant Initiative, the DOT Research and Innovative Technology Administration (RITA) organized a team of federal agency specialists to identify the nation’s leading research priorities to be addressed in order to develop renewable bio-based transportation fuels. These national priorities for renewable transportation development included: biofuel feedstock development, biofuels conversion processes, biofuel system analysis, economics, marketing and policy, and environmental impacts. Figure 1 highlights the primary topic area of awards made through this program as well as the funding associated with each.
A project at South Dakota Mines developed models to assist in evaluating biofuel production sustainability from nonfood oilseeds for the Northern Great Plains with respect to farm economics, life cycle impacts and transportation efficiency (Figure 2). These models can also be used to explore future biofuel and/or agricultural opportunities. In addition, undergraduate students on this project developed two easy to use ESRI ArcGIS story maps to describe potential use of oilseeds in the region:
- Farm-gate Life Cycle Assessment of Oilseed Feedstocks for the Northern Great Plains and
- Biodiesel Transportation Network for the Northern Great Plains
Regional oilseed life cycle inventories been made available within the new USDA Ag Data Commons. Availability of this dataset will assist in meeting future renewable fuel and biofuel regulatory requirements and pathway approvals.
A team led by researchers at the University of Minnesota developed a novel and efficient technology called Rapid Microwave Assisted Pyrolysis (rMAP) for transforming biomass into biofuels. This technology was adapted to smaller, distributed systems with the pilotscale processor fitting on the back of modest-sized trailer (Figure 3). Resynergi Inc. a California waste recovery company, is making use of this technology to commercialize a biorefining technology that converts both biomass and waste plastic into oil and gas Resynergi is broadening the range of feedstocks that could be processed by combining the microwave-based technology developed at the University of Minnesota to convert biomass such as waste wood or crop residue into oil with its own modular, microwave-based system to transform unrecycled waste plastic into biodiesel.
At North Dakota State University, a team of researchers is working to develop energy beets, a nonfood crop, as an economical sugar source to produce biofuels and bioproducts. Specifically, they evaluated ways to increase production of raw thick juice and reduce the transportation and storage challenges associate with energy beets (Figure 4). Their research helped identify the best alternatives to do this through frontend processing, storage and fermentation tests as well as computer modeling. Their interdisciplinary partnership contributed to ongoing efforts by the private and public sectors to establish an energy beet biofuels industry in the North Central U.S.
