钢铁如何减碳?宝钢PPT:技术路线、低碳产品、实施路径
《宝钢低碳钢铁技术策划及开发》介绍了宝钢股份在实现双碳目标方面的战略规划、技术路线、产品开发和应用情况。以下为主要内容：
1、宝钢股份减碳技术路线
（1）废钢+电炉：以废钢为主要原料，以电力为主要能源，生产钢铁产品，可大幅减少碳排放。宝武集团计划2030年前，扩大电炉钢产量到600万吨以上。
（2）高炉/转炉+废钢：利用现有高炉/转炉设施，通过大量加入废钢、直接还原铁等部分替代铁矿石，实现减碳。
（3）氢基竖炉+电炉：氢基竖炉以氢气替代碳还原剂，将铁矿石还原为铁，并通过使用清洁能源制取绿氢，可能实现钢铁生产的近零碳排放。宝钢湛江钢铁正在建设百万吨级氢基竖炉工程，预计2023年底投产。
（4）富氢碳循环高炉+CCUS：富氢碳循环高炉采用富氢还原剂，预期可实现减碳大于30%。宝钢已在八一钢铁400m3高炉完成二阶段工业试验。

2、宝钢股份绿色低碳产品：宝钢股份已开发多种绿色低碳产品，并建立绿色低碳产品认可体系。产品涵盖汽车钢、电工钢、光伏支架用钢等，满足不同用户的需求。宝钢股份与北京奔驰、日立能源等企业合作，推动绿色钢铁供应链发展。
3、低碳钢铁技术挑战：低碳钢铁技术的成本较高，需要通过技术创新、规模化生产等方式降低成本。绿色钢铁产品质量体系、碳排放核算体系、低碳标准体系等需要进一步完善。
