Greensteel Australia and global steelmaking technology leader Danieli will work together 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. 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.

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 the 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 NO_x 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 specialized technology to ensure successful operations through the steelmaking process. Danieli has delivered more than 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 maximizes production efficiency and minimizes 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 the advanced 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.
