摘要
Microalgae CO<sub>2sub> sequestering facilities might become an industrial reality if microalgae biomass could be produced at cost below $500.00 t<sup>鈭?sup>. We develop a model for estimation of total production costs of microalgae as a function of known production-specific expenses, and incorporate into the model the effects of uncontrollable factors which affect known production-specific expenses. Random fluctuations were intentionally incorporated into the model, consequently into generated cost/technology scenarios, because each and every logically interconnected equipment/operation that is used in design/construction/operation/maintenance of a production process is inevitably subject to random cost/price fluctuations which can neither be eliminated nor a priori controlled. A total of 152 costs/technology scenarios were evaluated to find 44 scenarios in which predicted total production costs of microalgae (PTPCM) was in the range $200-500 t<sup>鈭?sup> ha<sup>鈭?sup> y<sup>鈭?sup>. An additional 24 scenarios were found with PTCPM in the range of $102-200 t<sup>鈭?sup> ha<sup>鈭?sup> y<sup>鈭?sup>. These findings suggest that microalgae CO<sub>2sub> sequestering and the production of commercial compounds from microalgal biomass can be economically viable venture even today when microalgae production technology is still far from its optimum.
