Abstract: This study examines the techno-economic and environmental implications of utilizing green and blue ammonia for Singapore's future power plants. Two approaches are considered: cracking ammonia to produce hydrogen for power generation and directly using ammonia as a fuel. The analysis begins with a conceptual design of an ammonia cracking plant, followed by an economic assessment comparing the levelized costs of ammonia-to‑hydrogen conversion with those of direct ammonia utilization. Finally, the study evaluates greenhouse gas emissions and carbon abatement costs for each approach.
