Despite the many advantages of microalgae, the feasibility of large-scale cultivation requires significant amounts of carbon dioxide (CO₂) to enable high growth rates. A synergistic union typically proposed for the supply of CO₂ is the coupling of algal cultivation with emissions from power plants. This study investigates the sustainability of a novel microalgae platform coupled with coal-based flue gas. The proposed system consists of a novel photobioreactor (PBR) for the production of biomass followed by a two-stage dewatering process. A systems model, which quantifies the CO₂ and energy consumption of the proposed system, was developed, and the minimum biomass selling price (MBSP) was determined by a techno-economic analysis (TEA). TEA results indicate that a facility with the capacity to capture 30% of the emissions from a 1-MW power plant requires a biomass production of 1280 metric ton per year, which when scaled to a nth of kind facility can produce biomass at a MBSP of $2322 per ton. The environmental impact of the proposed facility was determined by a life cycle assessment methodology, and results indicate a carbon capture potential of 1.16 × 10⁴ metric tons of CO₂ equivalent. In addition, an energy analysis indicates a desirable net energy ratio of 0.1, which is lower than conventional PBRs. Discussion focuses on the requirements to reduce biomass production cost, including research investment areas for increasing productivity while decreasing energy requirements.

尽管微藻具有许多优点，但大规模种植的可行性需要大量的二氧化碳（CO ₂）才能实现高生长速率。通常提出的用于供应CO ₂的协同联盟是藻类栽培与发电厂排放物的耦合。这项研究调查了新型微藻类平台与煤基烟气的可持续性。拟议的系统包括用于生产生物质的新型光生物反应器（PBR），然后进行两阶段脱水过程。系统模型，可量化CO ₂开发拟议系统的能耗，并通过技术经济分析（TEA）确定最低生物质销售价格（MBSP）。TEA结果表明，一个具有捕获1兆瓦发电厂30％排放量的能力的设施每年需要产生1280公吨的生物质，如果规模扩大到第n种同类设施，则可以在MBSP上生产生物质每吨$ 2322。拟建设施的环境影响是通过生命周期评估方法确定的，结果表明碳捕集潜力为1.16×10 ⁴公吨CO _2。当量。另外，能量分析表明理想的净能量比为0.1，低于常规的PBR。讨论的重点是降低生物质生产成本的要求，包括研究投资领域，以提高生产率，同时降低能源需求。
