Iron and steel is the largest UK manufacturing industry in terms of energy demand and greenhouse gas (GHG) emissions. Currently, more than 6 Mt of steel per year are produced in six blast furnaces at two steelworks with specific energy consumptions of 19 GJ/t of steel and overall direct CO2 emissions of 13 Mt, contributing 25% to GHG emissions from UK manufacturing. Combustion of blast furnace gas (BFG) in the power station causes ~ 50% of CO2 emissions.In BREIN-STORM we propose to convert the BFG from steel mills into valuable products, such as hydrogen and pure carbon dioxide. This will be achieved by combining calcium and chemical looping gas-solid reactions (CaL-CLC). This four-year project comprises four interlinked work packages (WPs):1. WP1 will develop and scale up different multi-functional materials based on calcium oxide as sorbent and copper-oxide oxygen carriers. We will focus on increasing the stability over cycling operation and the sorption capacity of the materials. The produced material will be tested and characterised to examine longevity. The kinetics models will be derived to enable the scale up.2. WP2 will focus on the development and testing of the reactor. We will carry out the experimental demonstration and long-term testing under different reactive conditions in packed and fluidised bed configurations. The experimental results will be used to validate the reactor model. The knowledge gained both from the experimental and numerical activities will be used as guidance for future pilot-scale demonstration of the technology.3. In WP3, the CaL-CLC process will be integrated into the steelworks through a conceptual design. The techno-economic performance of the process will be compared with standard state-of-the-art technologies in the steel sector. The integration of renewables sources will be studied with the aim of designing a first 'green' steelworks plant.4. In WP4, the developed process will be evaluated on environmental impacts as well as social and policy implications.

就能源需求和温室气体排放而言，钢铁是英国最大的制造业。目前，两个钢铁厂的六个高炉每年生产超过600万吨钢，比能耗为19 GJ/吨钢，总直接二氧化碳排放量为1300万吨，占英国制造业温室气体排放量的25%。约50%的CO2排放是由发电厂的高炉煤气（BFG）燃烧产生的。在BREIN-STORM中，我们建议将来自钢铁米尔斯厂的BFG转化为有价值的产品，如氢气和纯二氧化碳。这将通过结合钙和化学循环气固反应（CaL-CLC）来实现。这个为期四年的项目包括四个相互关联的工作包：1. WP 1将开发和扩大基于氧化钙作为吸附剂和氧化铜氧载体的不同多功能材料。我们将专注于提高循环操作的稳定性和材料的吸附能力。生产的材料将进行测试和表征，以检查寿命。将推导动力学模型以实现放大。WP 2将专注于反应堆的开发和测试。我们将在填充床和流化床结构中进行不同反应条件下的实验演示和长期测试。实验结果将用于验证反应器模型。从实验和数值计算活动中获得的知识将用于指导今后的技术试点示范。在WP 3中，CaL-CLC工艺将通过概念设计整合到钢厂中。该工艺的技术经济性能将与钢铁行业的标准最先进技术进行比较。将研究可再生能源的整合，目的是设计第一个“绿色”钢铁厂。在WP 4中，将对开发过程的环境影响以及社会和政策影响进行评估。
