The ENERGIRON alliance of Tenova & Danieli is transforming global steelmaking through its hydrogen-ready Zero Reformer direct reduction technology, capable of cutting CO₂ emissions by up to 80%. Major projects include Hyundai Steel's $5.8 billion Louisiana plant, Vulcan Green Steel's 2.5 million metric ton Oman facility, & ArcelorMittal Dofasco's C$1.8 billion ($1.32 billion) Canadian decarbonisation project. The technology's unique in-reactor reforming eliminates the need for an external reformer, reducing plant size, cost, & energy consumption.
