In brief: The US Department of Energy has invested nearly $1.5 million in projects that will help establish large-scale seaweed farms for the purpose of making biofuel. The renewable energy sector is rapidly increasing in the diversity of clean energy sources.

SEAWEED ENERGY

The U.S. Department of Energy is investing in a novel source of future renewable energy in the form of seaweed. That’s right — seaweed energy. The Honolulu Star-Advertiser reports that the DOE is investing nearly $1.5 million in two projects that will help develop seaweed farms and explore harvesting methods.

Seaweed, in all its slimy glory, can be processed into a biofuel that could be used to power our homes and vehicles. The DOE’s Advanced Research Projects Agency-Energy (ARPA-E) program is funding projects across the country to make the large-scale cultivation of seaweed a reality, supporting another alternative to fossil fuel use.

Of the two latest projects funded, $995,978 went to Makai Ocean Engineering of Honolulu to help build an ocean simulating model that the will aid researchers in designing offshore seaweed farms, and $500,000 went to Kampachi Farms of Kailua-Kona to test harvesting methods for seaweed grown on these farms. Kampachi Farms will also develop an offshore seaweed farm.
