An attractive algal cultivation strategy is to use carbon dioxide emitted from power plants for autotrophic biomass assimilation. Such a carbon capture system with microalgae has the following advantages compared to other carbon sequestration technologies [484]:

— Algal system does not require high purity carbon dioxide.

— Algal system produces biofuels that can be used for electric power generation.

— Some flue gas impurities (nitrogen and sulfur oxides) can be removed as well and be used by algae.

A conceptual diagram for algal production and ADP integrated into a scheme with carbon dioxide mitigation and waste treatment processes is shown in Fig. 21.
