Moving Forward by Looking Back: Revisit Macroalgae

Large scale biomass production for biofuels from macroalgae in the marine environment was first tried in the late 60's. However, farming offshore posed challenges that resulted in failed culture attempts. Despite these hindrances, the energy conversion thru anaerobic digestion was successful since the composition of macroalgae makes it an ideal feedstock.
For the last 50 years, the technology for mass production of macroalgae has been developed in Asia, specifically, China. It is now considered the single largest product of aquaculture. Macroalgal cultivation has also now spread to Europe and America. One of the main advantages of production of biofuel feedstock offshore is that it does not compete with food production for land or water.
Revisit the idea of the large scale offshore cultivation of macroalgae for biogas production and its feasibility today as a viable source of renewable energy.
