Electride-catalyst low-temperature low-pressure ammonia synthesis
Ammonia synthesis using electride-based catalysts that operate at lower temperature and pressure than conventional Haber-Bosch iron catalysts, enabling smaller modular plants.
Problem solved
Conventional Haber-Bosch economics favor very large centralized plants; lower T/P synthesis reduces vessel and compressor requirements so ammonia can be made onsite at hundreds to tens of thousands of tonnes per year where H2 and N2 (or power for their production) are available.
Application contexts
- Onsite industrial ammonia for chemical feedstock and NOx control
- Distributed fertilizer production near agricultural demand
- Green ammonia linked to renewable hydrogen hubs
- Fuel / hydrogen-carrier demonstration plants
Technical principle
Electride materials (electron anions in a framework derived from work at Tokyo Tech / Hosono group) facilitate N2 activation; company states this yields higher TOF and lower activation energy than conventional catalysts, enabling operation in the ~3–5 MPa / 300–400°C range versus typical high-pressure HB conditions.
Typical use cases
- 500 t/y industrial onsite ammonia package
- Renewable-H2-fed green ammonia pilot at hydrogen parks
- Modular mid-scale plants where transport of liquid NH3 is costly or restricted
