Renewable and Sustainable Energy Reviews, 2015, vol. 52, issue C, 1781-1790

Abstract: This review evaluates the work which has been completed to date in the anaerobic digestion of seaweeds. In recent years, there has been significant interest in this area owing to the advent of peak oil and global warming creating insecurities in our reliance on fossil fuels. Seaweed as an energy source has the advantage of not using arable land for production and thus, not contributing to the food versus fuel debate in any significant way. Many macroalgal species have a high growth rate allowing for sustainable harvesting. Various different parameters have been highlighted in this work including macroalgal species, composition, temperature, pretreatments and system design. Ulva is one of the main species of interest at the present time owing to it׳s eutrophic effect creating problematic algal growth on many beaches.
