“…One of which was NASA's Offshore Membrane Enclosures for Growing Algae (OMEGA) project (Figure 9). This project utilized microalgae grown in semi-permeable membranes to treat wastewater and release clean water back into the ocean (Trent et al, 2012). Additionally, a small-scale study preformed at Cal Poly San Luis Obispo showed the ability of native microalgae to grow in dairy and municipal wastewater as a means to decrease biofuel production costs (Woertz et al, 2009).…”

“…57 Floating algal farming is an emerging nutrient removal/accumulation process from waste streams. This approach may be most appropriate in coastal regions where nutrients are discharged directly to ocean from agriculture activities 58 and thus can be recovered. The salinity gradient between waste streams and seawater has the potential to drive osmosis and help concentrate nutrients and dewater harvested algae.…”

“…Several reports estimated microalgal biofuel productivity using solar irradiance information , but they only analyzed a few locations or considered only land area when determining biofuel potentials. Land‐based open raceway ponds (ORPs) and closed photobioreactors (PBRs) have been the major technologies employed for algal cultivation, but development of water‐based algal culture systems has been reported recently, claiming various advantages over conventional land‐based systems . Thus, it would be worth including the vast ocean area in analysis of maximum microalgal biofuel productivity.…”

Microalgae have long been considered as one of most promising feedstocks with better characteristics for biofuels production over conventional energy crops. There have been a wide range of estimations on the feasibility of microalgal biofuels based on various productivity assumptions and data from different scales. The theoretical maximum algal biofuel productivity, however, can be calculated by the amount of solar irradiance and photosynthetic efficiency (PE), assuming other conditions are within the optimal range. Using the actual surface solar irradiance data around the world and PE of algal culture systems, maximum algal biomass and biofuel productivities were calculated, and feasibility of algal biofuel were assessed with the estimation. The results revealed that biofuel production would not easily meet the economic break‐even point and may not be sustainable at a large‐scale with the current algal biotechnology. Substantial reductions in the production cost, improvements in lipid productivity, recycling of resources, and utilization of non‐conventional resources will be necessary for feasible mass production of algal biofuel. Among the emerging technologies, cultivation of microalgae in the ocean shows great potentials to meet the resource requirements and economic feasibility in algal biofuel production by utilizing various marine resources.
