A novel photobioreactor design for efficient CO2 capture from industrial emissions using cyanobacteria

cyanoccapture的使命是利用光合作用的蓝藻，在工业规模上提供负担得起的碳捕获。这项突破性的技术使“真正的”碳封存技术能够广泛应用于世界各地的发电厂、钢铁和水泥工业等各种排放源。本研究提出的新发现菌株（PCC 11901）能够直接从排放场所吸收二氧化碳，并迅速将其转化为致密的固体物质（生物质），可以以低成本储存或利用。我们的愿景是成为世界上第一个将可扩展的碳捕获技术推向市场的公司，该技术的成本低于每吨二氧化碳50英镑。cyanoccapture处于技术准备水平4级-在实验室阶段验证概念验证；在模拟室外光照条件的pbr中收集了几个月的碳固定测定数据。我们的下一步是在室外系统中使用真实的烟气将其扩展到更大的5m x 5m单元，以进一步验证已证实的概念。cyanoccapture将在奇切斯特的一个农场建立多达四个PBR装置，并评估新的操作流程，以从一个中等规模的排放装置中捕获二氧化碳。每个PBR都是一个全封闭系统：5米× 5米× 0.5米的透明篷布水箱，配有电子和手动控制的气体入口/出口。该系统将培养非转基因蓝藻菌株，选择其快速碳封存潜力。

CyanoCapture's mission is to provide affordable carbon capture on an industrial scale by using photosynthetic cyanobacteria. The breakthrough technology enables 'true' carbon sequestration to become widely accessible to various emission sources such as power plants, steel and cement industries all over the world. The newly discovered strain (PCC 11901) proposed in this study is capable of taking CO2 directly from emission sites and rapidly convert it into a dense solid matter (biomass) that can be stored or utilised at low cost. Our vision is to become the first in the world to bring a scalable carbon capture technology to the market that has a cost below the £50/tonne CO2 mark.CyanoCapture is at Technological Readiness Level 4 - validation of proof-of-concept at the laboratory stage; having collected several months of carbon fixation assay data in PBRs mimicking outdoor light conditions. Our next step is to scale this to a larger 5m x 5m unit in an outdoor system using real flue gas to further validate the proven concept in situ.CyanoCapture will build up to four PBR units and evaluate novel operational processes to capture CO2 from a medium-scale emission unit in a farm in Chichester. Each PBR is a fully enclosed system: 5m x 5m x 0.5m transparent tarpaulin water tanks fitted with a gas inlet/outlet with electronic and manual control. The system will cultivate non-GM cyanobacterial strain, selected for its fast carbon sequestration potential.
