Decarbonizing the iron and steel industry by recycling emitted CO₂ into carbon-neutral input gas directly out of waste streams, no carbon capture required.

The Tough Tech problem we are solving

The steel industry depends on fossil fuels to produce syngas for converting iron ore into steel, with no drop-in replacement for existing facilities despite mounting consumer and regulatory pressure to decarbonize billions in high-emission infrastructure.

About our solution

Helix Carbon’s proprietary electrolysis system transforms captured CO₂ from iron furnace waste gas into emissions-free, carbon-neutral syngas using improved catalysts and cost-effective materials. As a drop-in solution for steelmaking, phosgene, and ethane cracking plants, it enables immediate decarbonization of petrochemical facilities, meets surging demand for green steel, and delivers cost-competitive feedstocks in fossil-reliant markets.
