Algae for Biofuels

Algae are an excellent source of oil for making biodiesel, which could displace substantial volumes of petrodiesel for heating and transportation. Microalgae reproduce rapidly, and they grow on non-agricultural land, so they don’t compete with food, feed, or fiber production. Algae utilize large amounts of CO2 gas and ‘waste’ nutrients from farm or municipal sources, so it can help to address climate change and wastewater cleanup.

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.

The profiles, publications, and links to the right and image gallery below provide more information on the work being done in Vermont and nationally to advance the commercialization of algae for biofuels and wastewater remediation.

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
Green Mountain Spark set about to demonstrate the feasibility of using photochemistry to create a single system for oil separation from micro-algae and biofuel production from the separated oil. The outcome of this research is an algae fuel processing system prototype capable of producing biofuel more cost effectively and with less energy investment compared to standard oil extraction and transesterification. Successful development of this technology will give microalgae oil biofuel producers a more efficient oil extraction and biofuel conversion process.
