Development and Techno-economic Assessment of Algal-based CO2 Capture

该项目的目的是评估利用光合微藻培养物从工业烟道气中有效和具有成本效益的碳捕获和利用（CCU）的潜力。将设计、运行和优化微藻CCU系统，以实现高效的碳捕获。实验数据将用于产生技术经济评估，包括总成本，资本支出和运营支出，所有这些都将用于优化最低成本和最高的碳捕获效率。目前，小球藻已经培养在不同的通气条件下，以提供参考点数据，用于与CO2升高条件下的生长进行比较。实验工作的下一阶段将涉及将藻类培养物暴露于逐渐升高的CO2浓度，直至一系列CO2排放者所看到的浓度。培养物生长的条件将被优化，以实现最高的CO2去除，最佳的生长和最低的成本。将考虑的参数包括：培养基组成，适用于培养的光照制度和使用不同的和新的微藻物种。微藻CCU的TEA模型已经产生，实验数据将用于产生成本分析。将在实验工作的每个阶段进行TEA，以比较每个参数变化及其对系统总体成本的影响，旨在优化系统以实现最低成本和最高的碳捕获效率。

The aim of this project is to evaluate the potential for efficient and cost effective carbon capture and utilisation (CCU) from industrial flue gases using photosynthetic microalgal cultures. A microalgal CCU system will be designed, operated and optimised for efficient carbon capture. Experimental data will be used to produce techno-economic assessments covering total cost, CapEx and OpEx, all of which will be used to optimise for lowest costs and highest carbon capture efficiencies.Currently, Chlorella sp. have been cultivated in different conditions of aeration to give reference point data for comparison with growth under elevated CO2 conditions. The next stage of experimental work will involve exposing the algal cultures to progressively higher concentrations of CO2, up to those seen by a range of CO2 emitters. The conditions under which the cultures are grown will then be optimised for highest CO2 removal, best growth and lowest cost. Parameters which will be considered include: media composition, light regime applied to the culture and the use of different and novel microalgal species.A TEA model for the microalgal CCU has been produced and the experimental data will be used to produce cost-analyses. A TEA will be conducted at each stage of the experimental work to compare each parameter change and the effect it has on the overall cost of the system with the aim of optimising the system for lowest cost and highest carbon capture efficiency.
