Any ore. Fines, lumps, waste oxides.
Through
Natural gas today. Hydrogen tomorrow.
Out
Tunable iron and steel. One step.
>20%
Below blast-furnace cost.
Conventional iron passes through four plants before it’s usable. Ours comes out of one furnace, from any grade of ore, on natural gas instead of metallurgical coal. Fewer plants means less capital and less energy in every ton you buy.
Modeled cost vs. the blast-furnace route
Four plants. One furnace.
HEAT 05
The people at the furnace.
Metallurgists, engineers and operators who have run a continuous furnace in Houston for two years, led by veterans of JSW Steel, AM/NS Calvert, Nucor, Blue Origin and Bechtel.
