Huhnke has been a team leader on several multidisciplinary, multi-institutional projects in converting low-cost biomass into liquid fuel and other value-added products using a gasification-fermentation process. Currently, he supports research in feedstock logistics and thermochemical conversion of biomass. From 2008-2013, Huhnke was the research coordinator on a five-year NSF EPSCoR Research Infrastructure Improvement Plan entitled “Building Oklahoma’s Leadership Role in Cellulosic Bioenergy”. According to Huhnke, “Some members of our society believe that biofuels compete with our petroleum resources. We must provide education to everyone – secondary education students through general public – about the benefits of biofuels and how we can use our biobased resources to develop alternative forms of energy to supplement our fossil fuels while reducing our dependence on foreign oil”.
