Optimization upstream CO₂ deliverable with downstream algae deliverable in quantity and quality and its impact on...

Algae CO₂ biofixation provides a promising opportunity due to earn carbon credits and valuable end uses. For balancing technology, energy and economy issues in practical utilization, this approach quantitively interprets the contradictions from upstream CO₂ source with a wide range of initial concentration to downstream CO₂ biofixation product including edible algae and algal biomass. The influence of upstream CO₂ deliverable on algal quantity and quality have been assessed, and the influence of CO₂ concentration on CO₂ transport mode choice has been also assessed coupling the transportation distance. In downstream algal fixation, quantitively relationship of algal growth have been established. The assessment discovered that direct energy consumptions complied with logarithmic relationship with specific productivities while both direct energy and indirect energy consumption complied with linear relationship with protein content. According to sensitive uncertainty analysis, initial CO₂ concentration is a critical parameter to influence significantly energy consumption in upstream CO₂ deliverables and algal quality while the contents of protein and specific productivity are the critical sensitive parameters in downstream algae deliverables. Potential modification systems are achieved for significantly reducing energy consumption by improving specific productivity and carbon abundance with low protein content in algae.
