CCSCOC - novel energy-efficient carbon capture technology for mineralising carbon in molten waste to support heavy industry to reach net-zero

** 需求 ** 钢铁和水泥的二氧化碳排放量占全球排放量的15%。需要包括碳捕获在内的一系列解决方案来使这些难以减少的行业脱碳并过渡到净零。英国政府推出了支持钢铁生产脱碳的政策，包括英国排放交易计划（ETS）和碳捕集与封存基础设施基金。钢铁行业的脱碳努力正在从传统生产技术（BF-BOF）转向替代技术（DRI-EAF）。这对水泥和钢铁行业有两个不利影响：1。降低了高炉矿渣粉（GGBFS）的可用性，而低碳水泥行业依赖矿渣粉作为辅助胶凝材料（SCM），并为钢铁生产商提供可观的收入来源。增加电弧炉（EAF）和不锈钢（SS）炉渣的产量，这些炉渣通常被填埋，制造商需要支付一定的成本。**机会 ** EAF/SS炉渣都是金属碳酸化反应的有效原料，可以隔离CO2，在某些情况下可以被增值并用作有效的SCM。然而，使用这些材料进行规模化碳捕获和SCM生产受到粉碎的高能量成本以及EAF和SS炉渣的不同矿物学的阻碍。两者都阻碍了这种十亿吨级协同方法的部署，以减少两个全球重要行业的碳化。解决方案 **Cocoon开发了一种独特的正在申请专利的工艺，可以捕获钢铁生产过程中产生的二氧化碳排放，并在同一生产过程中产生的熔融废物中将其矿化。这一概念已经得到验证（TRL 3）。现在，我们与利兹大学土木工程学院和材料加工研究所合作，打算将该工艺改进并扩大到工业水平-证明其对下一代钢铁生产中的炉渣的有效性（例如EAF和SS炉渣），这为深度脱碳提供了有利可图的途径，该技术具有十亿吨级二氧化碳去除的潜力-到2031年，Cocoon将获得每年2.74亿英镑的收入机会，其中约50%出口。

**Need**CO2-emissions from steel and cement account for 15% of global emissions. A portfolio of solutions, including carbon capture, is needed to decarbonise these hard-to-abate sectors and transition to net-zero. UKGOV has introduced policies to support the decarbonisation of steel-making , including the UK Emissions Trading Scheme (ETS), and the Carbon Capture and Storage Infrastructure Fund.The steel industry's decarbonisation efforts are shifting from traditional production techniques (BF-BOF) to alternatives (DRI-EAF). This has has two adverse effects on cement and steel industries:1. Reduced availability of ground-granulated blast furnace slag(GGBFS), which the low-carbon cement industry relies on as a supplementary cementitious material(SCM) and appreciable source of revenue for steel producers.2. Increased production of Electric Arc Furnace(EAF) and Stainless Steel(SS) slags, which are typically landfilled, at a cost-to-the-manufacturer.**Opportunity**Both EAF/SS slags are effective feedstocks for metal-carbonation reactions that sequester CO2, and in some instances can be valorised and serve as effective SCMs.However, scaling carbon capture and SCM production with these materials have been held back by high-energy costs of comminution, and varied mineralogy of EAF and SS slags. Both hampering the deployment of this gigatonne-scale synergistic approach to decarbonising two globally important industries.**Solution**Cocoon has developed a unique, patent-pending process that captures CO2-emissions made during steel production, and mineralises them within the molten waste from the same production process. The concept has been proven (TRL3).Now, working with with Leeds University's School of Civil Engineering and the Materials Processing Institute, we intend to refine and scale-up the process to industrial levels - demonstrating its effectiveness against slag from next-generation steel production (e.g. EAF and SS slags), enabling rapid commercialisation post-project.This provides profitable routes for deep-decarbonisation and the technology has the potential for gigatonne-scale CO2 removal - unlocking a £274m/annum revenue opportunity for Cocoon by 2031 with ~50% exports.
