Greensteel launches world first 100% hydrogen-powered rolling mill
The first-of-its-kind green steel facility is to be located in New South Wales, Australia, and will create a global benchmark for zero-emissions steel production. In a major step for sustainable steel manufacturing, Greensteel Australia has been awarded a contract by global steelmaking technology leader Danieli to build a 600,000-tonne-per-year rolling mill that will be powered entirely by green hydrogen.
The first-of-its-kind green steel facility is to be located in New South Wales, Australia, and will create a global benchmark for zero-emissions steel production. Danieli, an Italian-based metal processer and supplier, will partner with Greensteel Australia to develop the plant and is targeting commencement of operations by late 2026.
“It’s inspiring to partner with Greensteel Australia on this world-first hydrogen-powered rolling mill. Greensteel Australia’s commitment to clean, sustainable steelmaking is leading the industry toward a greener future. We’re thrilled to support their vision with our technology and work together to set a new standard in zero-emission steel production”, said Danieli Group’s CEO, Mr Giacomo Mareschi.
“At Greensteel Australia, we’re proud to partner with Danieli on this groundbreaking project. By using 100% green hydrogen, we’re not just building a new rolling mill, we’re setting a new example for clean steel production. This project shows our commitment to making steel in a way that’s better for the environment and for future generations”, said Green Steel Australia’s President, Mr Mena Ibrahim.
Iron and steel production is essential to economic prosperity and development, but also responsible for 8% of global CO2 emissions. Iron and steel production are considered our most carbon intensive and hard-to-abate industries. According to the International Energy Agency, emissions from steelmaking must be reduced by 50% by 2050 and then continue to fall, if the world is to meet its climate goals.
The mill will feature a reheating furnace powered by 100% green hydrogen, cutting out NOx emissions and effectively eliminating reliance on fossil fuel use. This advanced facility is designed to produce rebar in diameters from 10 to 50 mm and spooled coils from 8 to 32 mm primarily for the Australian construction market.
Under the announced agreement Danieli will offer quality materials, knowledge-sharing, and specialised technology to ensure successful operations through the steelmaking process. Danieli is a company renowned for its expertise in delivering over 500 rolling mills and global innovations in sustainable steel manufacturing.
This advanced facility will integrate Danieli’s sixth-generation horizontal billet welding technology, allowing endless rolling and continuous material flow to 14 housingless rolling stands. Equipped with a quick-change system, this design maximises production efficiency and minimises downtime during size changes. The mill’s six-pass Fast Finishing Block will further enhance performance, rolling smaller sizes at speeds of up to 40 meters per second and feeding both the bar and spooler lines.
In addition to cutting-edge production technology, the mill will be equipped with mechanical and electrical automation, overhead cranes, water treatment systems, compressed air plants, and a fully equipped rollshop. The use of automation will reduce overheads and optimise safety and efficiency.
This landmark project underscores Greensteel Australia and Danieli’s leadership in the global transition to zero-emission industrial practices.
