. Standing stock: 50 mill ton seaweed (ww) (Steen 2013, HI) . 99% of the biomass is kelp (Laminaria hyperborea and Saccharina latissima)(Gundersen et al. 2011, Niva) . Harvested annually (ww): – 150-180.000 tons kelp Laminaria hyperborean (FMC BioPolymer, Haugesund) – 15.000 tons Ascophyllum nodosum (Algea, Kristiansund)

. The use of algae for solemnly biofuels production is not profitable. . There is the need to develop new technologies able to guarantee a competitive algae-based products. . It is NOT only about cultivation and harvesting…
