Industries producing over 25,000 T CO2/year represent ~40% of the total emissions of stationary installations in Europe and are currently subject to a carbon tax at ~€100/T CO2 under the EU Emission Trading Scheme (ETS). These industries are desperately looking for affordable carbon capture technologies to reduce emissions, however, current prominently used direct air capture (DAC) is not commercially feasible at scale.CyanoCapture Ltd., the project lead, is an innovative SME aiming to develop a sustainable and cost-effective solution for point source carbon capture by combining novel photobioreactor processes and a fast-growing cyanobacterium, _Synechococcus_ sp. UTEX 3154 (Syn3154). Photosynthetic cyanobacteria are ubiquitous and account for 30-50% of environmental CO2 fixation. Cyanobacteria are naturally far more efficient than plants at capturing CO2 and hence are excellent candidates for scalable carbon capture. The cyanobacterium Syn3154 is a fast-growing, high biomass accumulating strain with a doubling time of less than 3 hours, with no need for external supplementation of vitamins for its growth -- meaning that it carries the potential to be an excellent candidate to enable mass-scale CO2 removal.The project partner UKBRC at the University of Edinburgh will develop a sustainable method for conversion of cyanobacteria biomass into stable biochar and evaluate applications such as agriculture, construction, sanitation, environmental management etc. that offer not only long-term carbon sequestration, but also additional economic and societal benefits. The proposed breakthrough solution enables affordable CO2 capture and has a strong potential to elevate the UK's position at the forefront of the global Net-Zero transition.

每年产生超过25，000吨二氧化碳的行业占欧洲固定装置总排放量的约40%，目前根据欧盟排放交易计划（ETS），碳税约为100欧元/吨二氧化碳。这些行业正在拼命寻找负担得起的碳捕获技术来减少排放，然而，目前主要使用的直接空气捕获（DAC）在商业上不可行。作为该项目的领导者，是一家创新型中小企业，旨在通过结合新颖的光生物反应器工艺和快速生长的蓝藻_Synechococcus_ sp. UTEX 3154（Syn 3154），为点源碳捕获开发可持续和具有成本效益的解决方案。光合蓝藻是普遍存在的，占30-50%的环境CO2固定。蓝藻在捕获二氧化碳方面自然比植物更有效，因此是可扩展的碳捕获的绝佳候选者。蓝细菌Syn 3154是一种快速生长、高生物量积累的菌株，倍增时间小于3小时，它的生长不需要外部补充维生素--这意味着它有潜力成为一个很好的候选者，规模CO2去除。爱丁堡大学的项目合作伙伴UKBRC将开发一种可持续的方法，将蓝藻生物质转化为稳定的生物炭和评估应用，如农业，建筑，卫生，环境管理等，不仅提供长期的碳固存，而且还提供额外的经济和社会效益。拟议的突破性解决方案能够实现负担得起的二氧化碳捕集，并有很大的潜力提升英国在全球净零过渡的前沿地位。
