Ammobia and Lummus to commercialize modular low‑capex ammonia (Haber‑Bosch 2.0)
- Ammobia’s Haber‑Bosch 2.0 runs at lower temperatures and pressures and is modular, enabling retrofit or incremental capacity.
- Ammobia claims capex reductions up to 50% and production cost cuts of 10–30% versus conventional ammonia plants.
- Lummus will add commercialization, reactor/process and thermal expertise and will include Ammobia as the first ammonia technology in its portfolio.
- Market drivers include a projected 58% rise in ammonia production by 2033 and 441 ammonia‑ready or ammonia‑fueled vessels on order or in service as of June 2026.
Partnership and technology
Ammobia will license its low‑capex, modular “Haber‑Bosch 2.0” ammonia synthesis to Lummus Technology for deployment in commercial installations worldwide. The process operates at lower temperatures and pressures than conventional Haber‑Bosch, uses a reengineered synloop, and is designed for standardized, medium‑scale units that can be added incrementally or retrofit existing sites. This technology is the first ammonia offering to join Lummus’ portfolio.
Commercialisation and project delivery
Lummus will provide engineering rigor, project execution, reactor/process and thermal expertise, and performance guarantees intended to make projects bankable and reduce development risk. Ammobia reports capex reductions up to half and total production cost savings of 10–30%. The partners say the design works with any energy source and can be integrated with Lummus’ hydrogen solutions.
Target markets and next steps
The companies will prioritise projects for power generation and maritime fuel, aiming to supply growing demand as ammonia becomes an energy carrier and shipping fuel. Market context cited includes a projected 58% increase in ammonia production by 2033 and 441 ammonia‑ready or ammonia‑fueled vessels as of June 2026. The partners will identify first commercial projects in the coming months.
