Compare the problem solved, constraints, readiness, and partnership route on each record.
Small-scale low-temperature low-pressure ammonia synthesis module
Modular ammonia synthesis system using electride catalysts enabling distributed production at reduced temperature and pressure compared to conventional Haber-Bosch process.
High capital cost and logistics barriers of centralized large-scale ammonia plants prevent local production in resource-limited or remote regions; long supply chains increase fertilizer and energy-carrier costs.
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.
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.
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.
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.
Onsite modular ammonia production system (electride catalyst package)
Skid/plant package that produces ammonia at the demand site using electride catalyst modules in the ~500–50,000 t/y class, reducing long-haul NH3 logistics.
Industrial and fertilizer users face shrinking domestic ammonia capacity and volatile import prices; onsite modules produce only the needed volume where hydrogen/nitrogen utilities exist, cutting dedicated transport and storage infrastructure.
Industrial ammonia dissociation unit for H2+N2 atmosphere gas
Electric catalytic ammonia cracker that produces mixed hydrogen-nitrogen atmosphere gas (nominal 3H2+N2) for heat treatment, sintering, and related industrial uses.
Users need a stable reducing/protective atmosphere without bulk hydrogen logistics; cracking liquid or vapor NH3 onsite yields a controllable H2-rich mixed gas with low residual ammonia and low dew point after drying.
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.
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.
Fuel-ammonia-oriented Fe-hydride catalyst commercialization pathway with EPC and catalyst manufacturer partners
Pre-commercial partnership structure linking university catalyst science, startup IP management, EPC engineering, and industrial catalyst manufacturing for mid-to-large fuel-ammonia synthesis applications.
Lab-scale advanced ammonia catalysts often stall before industrial use because IP, process engineering, and catalyst manufacturing sit in different organizations. Fuel-ammonia projects need a clear path from catalyst science to plant-integrable catalyst supply.
AX-gas ammonia dissociator for 75/25 hydrogen-nitrogen mixed gas
Catalytic ammonia dissociator that converts NH3 into a mixed gas of about 75% hydrogen and 25% nitrogen for industrial furnace atmosphere use.
Sites that need a hydrogen-rich reducing atmosphere (or a compact on-site source of H2+N2) can feed handled liquid/gaseous ammonia into a dissociator instead of storing large volumes of bottled hydrogen.
