Applications

Where clean iron and steel go.

From AI data centers to jet engines, it starts with clean iron and steel.

HEAT 03

Vision

It's time to leave 1850 behind. Our vision is to reinvent iron and steelmaking for a world that demands more, with fewer constraints on resources, energy, and cost.

HEAT 04

FLEX-HERS™. One furnace. Any ore.

In

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.
