Ammonia Power
Low-carbon generation systems based on ammonia-hydrogen co-firing
KHPS Ammonia Power Technology
Ammonia is a carbon-free clean fuel as a hydrogen carrier. KHPS supports the low-carbon transition of existing thermal power plants through ammonia-hydrogen co-firing technology. Ammonia can be easily stored and transported in liquid form, making it a practical alternative until large-scale hydrogen infrastructure is established.
Technology Development Status
1. Ammonia-Hydrogen Co-firing Technology
Ammonia has slow combustion speed and high ignition temperature, which can cause stability issues during single-fuel combustion. We have developed co-firing technology that mixes ammonia and hydrogen in appropriate ratios to improve combustion efficiency and minimize NOx emissions. Currently, we have achieved generation efficiency of over 43% at a 20% ammonia co-firing ratio.
2. Combustion Control System
To address combustion instability depending on ammonia co-firing ratio, we applied real-time combustion state monitoring and adaptive control algorithms. This maintains stable combustion even during load fluctuations.
3. Emission Control Technology
To eliminate unburned ammonia and NOx that may be generated during ammonia combustion, we introduced selective catalytic reduction (SCR) systems and secondary combustion chambers. This maintains emission levels that meet atmospheric environmental standards.
Key Cases
2024 Demonstration Project
We constructed a 10MW-class ammonia-hydrogen co-firing demonstration plant in Dangjin, Chungnam Province, and demonstrated stable operation at a 20% ammonia co-firing ratio. Currently, we are advancing technology with a target of 30% co-firing ratio.
Future Plans
- 2026: Target for commercialization of 30% ammonia co-firing
- 2028: Completion of 50% ammonia co-firing technology development
- 2030: Plan for commercial operation of 100MW-class ammonia co-firing power plant
