项目摘要

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.

该项目的目的是评估使用光合微藻培养物从工业烟道气中获得有效且具有成本效益的碳捕获和利用率（CCU）的潜力。将设计，操作和优化的微藻CCU系统以有效地捕获碳。实验数据将用于产生涵盖总成本，资本支出和OPEX的技术经济评估，所有这些评估将用于优化最低成本和最高碳捕获效率。已经在曝气的不同条件下培养，以提供参考点数据，以与二氧化碳条件下的生长进行比较。实验工作的下一个阶段将涉及将藻类培养物暴露于逐渐浓度的CO2，直到一系列CO2发射器所看到的二氧化碳。然后，将对培养物的种植条件进行优化，以最高的二氧化碳去除，最佳生长和最低的成本。将考虑的参数包括：培养基组成，应用于培养物以及使用不同和新型的微藻物种。已经生成了微藻CCU的茶模型，并将使用实验数据来生产成本量。在实验工作的每个阶段将进行茶，以比较每个参数更改及其对系统整体成本的影响，以便以最低的成本和最高的碳捕获效率来优化系统。
