FLEX-HERS™ TECHNOLOGY
One furnace.
Any ore.
Hertha Metals™ makes iron and steel from ore in a single step, at more than 20% lower cost than the blast furnace route. Natural gas today, hydrogen tomorrow.
HEAT 01
One platform. Three energy sources.
Flex-HERS™ is our proprietary platform, powered by natural gas, hydrogen and electricity.
It makes steel from any grade of iron ore or waste oxide, in any form, including fines and lumps. Not just costly DRI-grade pellets.
The process is semi-continuous and single-step, with tunable iron and steelmaking in the same furnace.
→ In
Any ore. Fines, lumps, waste oxides.
Low-grade ore and waste oxides become usable feedstock. No pelletizing, no sintering.

>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 04
Low-emission steel now. No stranded assets later.
Flex-HERS™ uses domestic iron ore and natural gas to make low-emission steel today, then switches to clean hydrogen as it becomes available. Same furnace. Nothing to replace.
