Algae Biofuel – Vermont’s Search for Viable and Cost-Effective Methods
With funding from the US Department of Energy secured by US Senator Patrick Leahy, the Vermont Bioenergy Initiative has supported a number of algae biofuel research projects. This early-stage research and development was undertaken to determine the most viable and cost-effective methods for accessing algae’s commercial potential to produce clean renewable energy while treating wastewater and supplying nutrient-rich feeds and food.
Algae produces more than half of the oxygen on the planet, while consuming vast amounts of heat-trapping carbon dioxide and taking up nutrients like nitrogen and phosphorous to make biomass and energy. The lipids, or oil, that algae produce can be extracted and processed into renewable fuels such as biodiesel. Algae are an excellent source of oil for making biodiesel, which could displace substantial volumes of petro-diesel for heating and transportation. Microalgae reproduce rapidly, and they grow on non-agricultural land, so they do not compete with food, feed, or fiber production.
The keys to commercializing algae for biofuel production include identifying and cultivating native species, optimizing growing conditions in natural and artificial environments and the efficient harvest and oil extraction of algal biomass. At the forefront of this algae biofuel research is Dr. Anju Dahiya, cofounder of General Systems Research, LLC, lead biofuels instructor at the University of Vermont’s Rubenstein School of Environment and Natural Resources, and Vermont Bioenergy algae for biofuel grant recipient. Dr. Dahiya has been searching for high lipid algae strains, and scaling those up to a level that could be available for commercial use, especially for biofuels.
“At GSR Solutions, we are looking at producing algae not just for biofuels, but combining it with waste water treatment and to produce other valued byproducts as well. This is very significant, because this would make algae production cost-effective. This would also help in nutrient recovery,” says Dahiya.
innovative new textbook that provides insight into the potential and current advances and benefits of biofuel
Some of the findings and knowledge afforded by Dr. Dahiya’s research are available in the new introductory textbook, Bioenergy: Biomass to Biofuels, which was edited by Anju Dahiya less than a year ago and represents a compilation of work from an extensive list of well-respected university extension programs, such as The University of Vermont Research Extension, as well as numerous national organizations including the US Department of Energy’s National Renewable Energy Laboratories. Dr. Dahiya will also be using this textbook as the basis for a University of Vermont Bioenergy Course offered for the 2015 fall semester.
