本レビューは、再生可能エネルギー統合マイクログリッドによる低炭素アンモニア生産の技術経済・環境・運用性能を評価する。LCOAは規模や構成で大きく変動し、1000t/日超の大規模系では条件次第で500USD/tNH3未満も可能。ハイブリッド構成と柔軟運用は水素貯蔵を84〜96%削減し、LCOAを最大22〜30%低減、GWPも約90%削減できる。
English
This review evaluates renewables-integrated microgrid configurations for low-carbon ammonia production across techno-economic, environmental and operational dimensions. Reported LCOA varies widely with scale and configuration; large systems above 1000 t/day can reach below 500 USD/tNH3 under favorable conditions. Hybrid renewables and flexible operation cut hydrogen storage needs by 84–96% and LCOA by up to 22–30%, while reducing global warming potential by ~90% versus conventional production.

📄 Abstract(原文)
Ammonia is a promising hydrogen carrier but its production must transition toward low-carbon pathways. This review evaluates renewables-integrated microgrid configurations for low-carbon ammonia production focusing on techno-economic, environmental and operational performance. Cross-study analysis shows that reported Levelized Cost of Ammonia (LCOA) varies substantially with production scale, renewable configuration and economic assumptions. Large-scale systems above 1000 t/day can achieve LCOA below 500 USD/tNH 3 under favorable conditions although higher values are reported for some locations. Renewable-generation infrastructure contributes approximately 25–62% of LCOA while electrolyzers account for up to 51% in some systems. Hybrid renewable configurations and flexible operation can reduce hydrogen-storage requirements by 84–96% and LCOA by up to 22–30%. Renewable-microgrid-based ammonia can also reduce global warming potential by approximately 90% compared with conventional production. Overall, competitive LCOA requires integrated optimization of renewable generation, electrolyzer capacity, storage, production scale and microgrid operation.
