Iron-hydride catalyst for low-temperature low-pressure ammonia synthesis
Non-precious-metal iron catalyst system with hydride promoter enabling ammonia synthesis from N2 and H2 at substantially lower temperature and pressure than conventional Haber-Bosch industrial iron catalysts.
AI-assisted directory summary. Technical specifications, performance metrics, readiness and compliance labels are unverified unless individually supported and reviewed. Proposed partnership routes do not establish supplier consent, export eligibility, or willingness to sign an NDA. Confirm claims and test conditions with the linked sources and supplier before procurement or citation.
Problem solved
Conventional Haber-Bosch ammonia synthesis requires high temperature and high pressure (classically hundreds of °C and multi-MPa to tens of MPa), driving energy use, CO2 intensity when powered by fossil heat/compression, and barriers to smaller or renewable-coupled plants. Precious-metal (e.g. Ru) alternative catalysts raise cost and supply-chain concentration risk.
Application contexts
- Fuel ammonia production cost and energy reduction
- Green ammonia from renewable hydrogen
- Potential retrofit or new-build Haber-Bosch catalyst evaluation
- Distributed or mid-scale ammonia synthesis studies
Technical principle
Iron-based catalyst combined with metal hydride (aluminum hydride / hydride-iron inverse structure per Science Tokyo public description) increases electron donation to iron surface sites that cleave N≡N, raising ammonia formation rate at lower T/P. Public MOU text cites demonstrated synthesis under low-temperature low-pressure conditions (e.g. on the order of 100°C and 1 MPa in partner communications); Science Tokyo 2025 release describes inverse-structure hydride-iron formed in situ from Al-treated iron oxide under synthesis conditions and higher volumetric activity versus industrial iron catalyst in lab comparisons.
Typical use cases
- Evaluation of Fe-hydride catalyst lots for ammonia synthesis pilots
- Joint development of low-T/P ammonia process packages with EPC partners
- Non-Ru catalyst option screening for green fuel-ammonia projects
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: target operating temperature and pressure · H2/N2 feed purity and source (green/blue/grey) · desired ammonia productivity (t/d or Nm3/h) · catalyst form factor (pellet/powder/structured) · lifetime and poison constraints · IP licensing vs catalyst supply preference
