This project aims to develop and apply a new route of lump iron ore pre-reduction with hydrogen or H2-enriched gases for ironmaking to minimise CO2 emission from steel production. The route will be built up on the base of H2 reduction kinetics of iron ore and with novel technologies such as CO2 recycle and H2-heating using hot blast, underpinning the hydrogen economy by addressing the environmental concerns in mineral and steel industries. It is not only significant for low-carbon steel production, but also for better fundamental understanding to develop the future zero-emission iron and steelmaking with hydrogen. The project will be very beneficent because it increases the use of lump iron ore and expends Australian export of iron ores.

该项目旨在开发和应用一种新的块铁矿石预还原氢或富氢气体炼铁路线，以最大限度地减少钢铁生产中的二氧化碳排放。这条路线将建立在铁矿石氢气还原动力学的基础上，并采用二氧化碳回收和热风加热氢气等新技术，通过解决矿产和钢铁行业的环境问题来支持氢经济。发展未来的零排放炼铁和氢气炼钢，不仅对低碳钢的生产具有重要意义，而且有助于更好地从根本上认识这一问题。该项目将非常有利，因为它增加了块铁矿石的使用，并增加了澳大利亚铁矿石的出口。
