本論文は、既存の天然ガスベースのアンモニアプラントに再生可能エネルギー由来の水素を部分的に導入するハイブリッド方式の技術経済評価を実施。カリフォルニアのデータに基づくケーススタディにより、太陽光と風力の補完性が水素とアンモニアの均等化コスト低減に有効であることを示し、炭素回収との組み合わせ（ハイブリッドブルーグリーン）への移行経路も提示している。
English
This paper presents a techno-economic assessment of a retrofit hybrid concept for ammonia plants, where renewable hydrogen is integrated into a conventional natural-gas-based process. Using California data, it shows that solar-wind complementarity reduces the levelized cost of hydrogen and ammonia, and outlines a pathway for combining hybrid operation with carbon capture as a transitional strategy.

In the global GX context
This paper provides a practical retrofit strategy for the global ammonia industry, which is a hard-to-abate sector. The hybrid approach, combining fossil and renewable hydrogen with potential carbon capture, offers a transitional pathway relevant to regions like Europe and North America that are implementing carbon pricing and hydrogen strategies.

📄 Abstract（原文）
Industrial ammonia synthesis remains a high-impact decarbonization target due to the combined effect of large production volumes and reliance on CO2-intensive fossil-based hydrogen. Replacing it partially with renewable-based (green) electrolytic hydrogen can minimize direct emissions; however, the intermittency of solar and wind complicates retrofit strategies for existing continuous plants. This paper addresses a techno-economic study centered on a retrofit-oriented hybrid concept: a conventional natural-gas ammonia plant is operated within a pre-defined “hybridization envelope”, where part of the process hydrogen is supplied by a renewable Power-to-Hydrogen subsystem. A steady-state process model (gray/blue baselines) is coupled with an hourly energy dispatch and a sizing optimization of solar/wind park, electrolyzer, battery, and hydrogen storage. A case study based on 2024 California data for renewables and carbon pricing illustrates how hybridization can reduce carbon intensity while ensuring all process constraints are met, and how the optimal renewable mix trades off between overbuild and storage. Results highlight the role of solar-wind complementarity in lowering the levelized cost of hydrogen and, consequently, the levelized cost of ammonia, while leaving a clear pathway for combining hybrid-green operation with carbon capture (hybrid-blue-green) as a transitional strategy.
