New seaweed cultivation structure may open up ocean floors for energy production

In Norway, Seaweed Energy Solutions has patented the first ever modern structure to enable mass seaweed cultivation on an industrial scale in the world¹s oceans. The structure, known as the Seaweed Carrier, makes a clean break with past seaweed cultivation methods that have all been based on ropes. The Seaweed Carrier is a sheet-like structure that basically copies a very large seaweed plant, moving freely back and forth through the sea from a single mooring on the ocean floor.

The Seaweed Carrier will allow seaweed cultivation to become a possibility in deeper and more exposed waters, opening the way for large scale production that is necessary to make seaweed a viable source of energy. According to SES,  growing seaweed in farms covering an area of just less than 0.05 percent of Europe’s coastal regions would yield a yearly production of 75 million tons of seaweed. This biomass could be converted into an estimated 846 Mgy (3.2 billion litters) of ethanol, about 4.7 percent of the global ethanol production in 2008.
