钢铁制造商在试验炉中以氢代煤
Steelmaker replaces coal for hydrogen in test furnace
Kallanish（开阑商务信息咨询）获悉，新日铁公司在使用氢气代替煤炭的试验炉中实现43%的二氧化碳减排，提前实现开发目标。
Nippon Steel Corporation has achieved 43% CO2 emission reduction in a test furnace using hydrogen instead of coal, reaching the development goal ahead of schedule, Kallanish learns.
该公司是日本最大的钢铁制造商，自称是世界上第一家在氢基高炉中实现二氧化碳减排40%以上的企业。
The company, Japan’s largest steelmaker, claims that it is the first one in the world to achieve CO2 emission reduction of over 40% in a hydrogen-based blast furnace.
试验炉位于东日本工厂君津地区，内部容积仅为12立方米。2022年实现的二氧化碳减排量为22%，2023年达到33%。
The test furnace is located at the East Nippon Works Kimitsu Area, with an inner volume of just 12 cubic metres. The CO2 reduction result achieved in 2022 was 22%, followed by 33% in 2023.
氢基高炉是该公司为减少炼钢过程中的排放而正在测试的三种工艺之一。其他两种工艺是氢基直接还原铁（DRI）和大型电弧炉炼钢。
Hydrogen-based blast furnace is one of three processes being tested by the company to reduce emissions in steelmaking. The other two are hydrogen-based direct reduced iron (DRI) and high-grade steel production in large-size electric arc furnaces.
新日铁补充道：“新日铁将继续开发可将炼钢过程中的二氧化碳排放量减少50%以上的技术，包括开发扩大技术，并加快在大型高炉中实际应用的努力。”
“Nippon Steel will continue to develop technologies that reduce CO2 emissions from the steelmaking process by more than 50%, including the development of scale-up technology, and accelerate efforts aimed at practical use in large blast furnaces,” Nippon Steel adds.
根据其“2050年碳中和愿景”，该钢铁制造商计划到2030年将二氧化碳排放量比2013年减少30%，并在2050年实现碳中和。
Under its Carbon Neutral Vision 2050, the steelmaker plans to cut CO2 emissions by 30% by 2030 compared to the 2013 baseline, and achieve carbon neutrality in 2050.
大型高炉的减排目标是50%以上。东日本工厂君津地区的2号高炉于去年2月开始安装设备，其规模约为试验炉的400倍。新日铁计划在2026财年进行示范试验。
The carbon reduction target of large blast furnaces is 50% or more. Equipment installation of No.2 BF at the East Nippon Works Kimitsu Area, which is approximately 400 times larger than the test furnace, started in February last year. Nippon Steel plans to conduct demonstration tests in fiscal 2026.
