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.
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
