Photobioreactor-Based Energy Sources
Abstract Microalgae are a potential candidate as a feedstock for biofuels and bioproducts in addition to remediate flue gas streams and wastewater. On an industrial scale, algae are grown in photobioreactors of which there are currently three styles: open, closed, and algal film. Open photobioreactors have the lowest capital cost, but suffer from lower productivity and contamination issues, while closed photobioreactors have high capital cost, but culture conditions are easier to control. Algal film photobioreactors are still in the developing phase, but show promise in reducing downstream processing costs due to their high algal biomass concentration. Algae are used to produce fuel products such as biodiesel, biocrude, ethanol, and biogas as well as producing high-value-added products. There are challenges with growing algae for fuel products associated with the high capital cost and processing costs of algae. To mitigate the high capital costs, building-integrated photobioreactor is a promising solution since the photobioreactor can serve multiple functions such as dissipating heat and removing CO2 from the flue gas stream. In these applications, closed photobioreactors are the most promising since they have a wide range of configurations and culture control.
