Jeonbuk National University Develops Dual-Chemical Looping for Greener Ammonia Synthesis
Event summary
- Researchers at Jeonbuk National University developed a dual-chemical looping method combining Al2O3 and Fe2O3 for ammonia synthesis, published in Energy Conversion and Management on January 15, 2026.
- The new process improves energy and exergy efficiencies by 8.4% and 19.0% respectively compared to conventional Haber–Bosch methods.
- The method reduces global warming potential by up to 15.85 kg CO₂-equivalent per kilogram of ammonia produced.
- Simulation results confirmed the proposed configuration's robustness and lowest production costs among evaluated cases.
The big picture
Ammonia is critical not just for fertilizers but also as a potential hydrogen carrier and low-carbon fuel. Conventional production via the Haber–Bosch process contributes 1–1.3% of global emissions, making this breakthrough significant for decarbonizing industrial processes. The dual-chemical looping method could reshape the ammonia synthesis market by offering a more sustainable and cost-effective alternative.
What we're watching
- Commercialization Pace
- How quickly the dual-chemical looping technology can be scaled for industrial adoption.
- Competitive Advantage
- Whether the efficiency gains can sustain a market edge over conventional ammonia production methods.
- Regulatory Impact
- The extent to which government policies on carbon emissions will accelerate or hinder deployment.
