Nippon Steel successfully produced direct-reduced iron from low-grade iron ore using 100% hydrogen in a trial, with cumulative production exceeding 1,000 tonnes during more than 300 hours of continuous operation.
Nippon Steel conducted trial production of direct-reduced iron from low-grade iron ore using 100% hydrogen and announced the initial results. This establishes the feasibility of trial production using a new technology that uses hydrogen as the reducing agent.
Continuous operation exceeded 300 hours, and the company said it used the extended operating period to assess stability and practicality.
Cumulative production in the trials to date has exceeded 1,000 tonnes of direct-reduced iron. Details of specific production conditions and benchmark conditions are limited to the information provided in the article.
