Algae Farm Model
Abstract: This model pathway focuses on process and TEA modeling for the production of algal biomass. The model reflects a hypothetical commercial-scale algae farm, inclusive of operations for cultivation, harvest/dewatering, inoculation, circulation, and storage (downstream conversion to fuels or products is outside the scope of this model). TEA modeling is conducted primarily to: (a) highlight key process/research needs and drivers required to achieve future minimum biomass selling price (MBSP) goals under mature “nth-plant” model projections, and (b) to help prioritize and track research progress under Algae Platform efforts relative to those goals. TEA modeling has been conducted reflecting various phototrophic cultivation
systems, including both open ponds and closed photobioreactors (PBRs). In 2016, NREL published a design report documenting the process, TEA details, and resultant MBSP outputs for several example open pond farm designs, accompanied by a published Excel-based TEA modeling tool of the system; subsequently, in 2019 a technical report was published documenting similar details for PBR system designs.
