Evaluate the techno-economic feasibility and production costs of offshore wind-powered green ammonia systems across three distinct global marine sites for 2035 and 2050.
Applied a pseudo-dynamic capacity optimization modeling framework utilizing long-term wind data to account for multidecadal wind variability.
Evaluated three offshore regions: La Guajira (Colombia), the North Sea (Denmark), and the Gulf of Roses (Spain).
Modeled solid oxide electrolysis cell (SOEC) systems coupled with flexible versus inflexible Haber–Bosch loop configurations under future cost and capital expenditure trajectories.
Modeled 2050 levelized costs of ammonia at 436 USD t⁻¹ in the North Sea, 472 USD t⁻¹ in La Guajira, and approximately 720 USD t⁻¹ in the Gulf of Roses.
Flexible and inflexible Haber–Bosch operations integrated with SOEC electrolysis resulted in minor differences in levelized production costs.
Inflexible Haber–Bosch plant operation led to a higher frequency of hot-standby events, indicating an operational trade-off between loop stability and required energy storage capacity.
