The brief
- US startup funded by the Department of Energy to decarbonise ironmaking via hydrogen-based reduction.
- Chalyx plant in Texas produces high-purity steel- and magnet-grade iron for EV motors and specialty applications.
- Series A \$133.65M includes \$65M from DOE's Industrial Decarbonization Program (IBAS).
Technical approach
Hydrogen Blend
Hydrogen and natural gas blend
Uses hydrogen/natural gas mixture as reducing agent, lowering near-term hydrogen cost while cutting emissions.
Single Reactor
Simplified rotating vessel design
Single rotating reactor vessel simpler than multi-stage fluidised beds, reducing capital cost and operational complexity.
High-Purity Output
Steel- and magnet-grade iron
Output refined for steel-grade (EV structural parts) and magnet-grade (EV motor magnets) with ≥99.5% purity.
Texas Location
Natural gas and electricity access
Sited in Texas near natural gas pipelines and electrical infrastructure. Close to Gulf Coast battery plants.
