On-site low-temperature low-pressure ammonia synthesis module
Compact ammonia synthesis system using electride-supported catalyst enabling production at reduced temperature and pressure compared to Haber-Bosch, targeted at distributed or on-demand ammonia supply.
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
High capital and energy intensity of conventional large-scale centralized ammonia plants; high logistics costs and boil-off for transporting ammonia or hydrogen over long distances; barriers to using renewables for ammonia production at smaller scales or remote sites.
Application contexts
- green ammonia production from renewable hydrogen
- on-site fertilizer or chemical feedstock supply
- hydrogen carrier production near demand or renewables
- maritime or industrial e-methane / ammonia fuel chains
Technical principle
Electride catalyst (composite of mayenite-type compound with supported active metal) facilitates ammonia synthesis from N2 and H2 at lower temperature (~200-400°C range implied) and pressure than standard 400-600°C / 20-100 MPa Haber-Bosch, allowing smaller reactor volumes and on-site deployment.
Typical use cases
- Distributed ammonia production at 500 t/y scale integrated with water electrolysis and renewable power for local fertilizer or H2 carrier output.
- Modular units for blue/green ammonia demonstration projects or early commercial on-site supply.
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: target production capacity (t/y) · feedstock (green H2 vs blue) · site constraints (footprint, utilities) · integration requirements (with electrolyzer or existing plant) · desired certification or LCA data
