Seaweed-into-Biofuel Project Gets Department of Energy Support
by Joanna McWilliams (Colorado State University) A Colorado State University project to grow and harvest ocean macroalgae for biofuel production has received support from the Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E).
ARPA-E has poured over $22 million into their Macroalgae Research Inspiring Novel Energy Resources (MARINER) program, with the aim of establishing the U.S. as a leader in biofuel production. CSU Energy Institute Researcher Jason Quinn’s project was one of 18 recently selected. Quinn is also an assistant professor in the Department of Mechanical Engineering.
The project is led by Pacific Northwest National Lab Research Engineer Michael Huesemann and is initially being awarded $500,000 over the course of one year, but may be considered for further funding.
ARPA-E was created in 2007 under President George W. Bush to fund research in innovative technologies for tackling energy challenges. One such challenge is making biofuels affordable and competitive. Biofuels originate from living matter, such as plants, as opposed to fuels like coal that are created via geologic processes.
A three-mile ocean cable
The ambitious CSU project involves a high-tech, three-mile-long recycled carbon fiber cable adrift in the open ocean. The cable will be automatically seeded and set afloat equipped with buoys and GPS sensors. The ultimate goal is to develop a new, economically sound method for producing and harvesting seaweed for biofuels.

Life-cycle assessments
At all stages, Quinn will conduct techno-economic analysis to gauge the economic feasibility of the project. Quinn will also complete a life-cycle assessment to determine the carbon savings and environmental impact of their method. The team aims to float their macroalgae-harvesting-cable off the coast of Washington within three years. READ MORE
