Techno-economic and sustainability assessment
Economic challenges as well as critical success factors have been identified for future seaweed-to-fuel technologies assuming industry scales. The techno-economic assessment, evaluated the technical and economic feasibility of industrial scale production of biofuels from seaweed based on the MacroFuels concept and found that biomass production and the equipment that is required for the automated harvesting results in biomass costs that are, although significantly lower than to date, still one to two orders of magnitude too high for competitive fuel applications only.
If the seaweed-to-biofuel value chain was integrated in a cascading biorefinery concept, in which other compounds are extracted for high value products (i.e. food, feed, cosmetics, pharma- and nutraceuticals, biomaterials etc.) the economic feasibility of seaweed as biomass for biofuels might shift to the positive side. MacroFuels will discuss this with relevant projects that look into seaweed biorefineries during the final project phase and consider results for exploitation and follow-up actions.
