Operation of an industrial-scale growth system was modeled
leveraging literature data for the energy requirements and productivity.
The industrial-scale system was assumed to produce at a
rate of 13 g m2 d1 based on an open raceway pond requiring
2.72 MJ (kg microalgae)1 with a harvest concentration of
0.5 g L1 [29,34,46–48]. In the scaled system the carbon, nitrogen
and phosphorus ratios remain unchanged from the experimental
data. The source of nitrogen is supplied using urea, and the phosphorus is supplied through diammonium phosphate as these
sources represent economically viable nutrient sources with
experimental data supporting microalgae growth on these sources
[50,63]. Carbon dioxide is supplied through co-location with an
industrial point source, such as coal derived flue gas [64].
