This study proposes a novel Heat Recovery Multi-Stage Seawater Vacuum Distillation for Electrolytic Water and Ammonia Generation Process (HR-SDEA) that integrates waste heat recovery, multi-stage desalination, and ammonia synthesis for modular offshore green ammonia production. Compared to the baseline SDEA, it reduces external steam reliance by 40%, GHG emissions by 11.58% per ton of ammonia, and non-renewable energy demand by 9.56%. Against traditional coal-to-ammonia, it cuts carbon emissions by 87.68% and energy consumption by 83.89%.

📄 Abstract（原文）
Ammonia, as a strategic hydrogen derivative, enables intercontinental energy trade. However, marine applications lack thermal integration studies under spatial and intermittent constraints. Herein, we propose a novel Heat Recovery Multi‐Stage Seawater Vacuum Distillation for Electrolytic Water and Ammonia Generation Process (HR‐SDEA) that synergistically combines waste heat recovery with multi‐stage seawater desalination and ammonia synthesis. This advanced configuration reduces external steam reliance by 40% through repurposing electrolyzer waste heat compared to Seawater vacuum Distillation for Electrolytic water and Ammonia generation process (SDEA), with a modular design suiting offshore environments. Compared with SDEA, the non‐renewable energy demand (NED) decreases by 9.56% and greenhouse gas (GHG) emissions reduce by 11.58% per ton of ammonia. Particularly, this configuration reduces carbon emissions by 87.68% and energy consumption by 83.89% over traditional coal‐to‐ammonia process (CTA) technologies. Combining thermal optimization and modularity, this work breaks bottlenecks for green H 2 ‐NH 3 chains, enabling viable offshore ammonia.
